Operating conditions Operating conditions Intended use The gearbox is exclusively designed and manufactured to be used as part of a drive unit to drive a conveyor or plow.

It reduces the speed and transmits the torque of a fixed electric motor to the drive shaft of the conveyor or of the plow drive.

When combined with additional equipment, the gearbox can be used to couple or clamp the conveyor chain.

Permissible equipment for this are: – Hydraulic or pneumatic chain tensioner as a tail-end drive on the gearbox connection assembly, if the drive connection assembly has been prepared for this.

– Fixing brake (arresting brake) Use the gearbox only as intended.

Unauthorized use includes: coupling or tensioning the conveyor chain using the conveyor drives or the plow drives.

Caterpillar does not accept any liability for any damage resulting from any such unauthorized use.

Ambient conditions Suitable measures must be taken by the operator to combat explosion hazards due to firedamp or the ignition of dust which might occur in a mine (see prEN 1710).

These include: adequate and consistent ventilation furrow spraying system/water spraying system If the mine gas concentration in the free cross section of the consistently ventilated areas of the face exceeds a certain percentage of the lower explosion limit (LEL) as defined in the respective national laws, the M2 equipment has to be switched off.

It may be switched on again by authorized persons only.

The atmosphere in the mine should be monitored at hazardous points to allow the power supply of all devices to be switched off, except those which are relevant for safety and suitable for use in explosive atmospheres.

The M2 equipment has to be stopped at once and secured against being switched on again if firedamp protection facilities are found to be damaged.

Paying careful attention to the points in this chapter will also help you to simplify your day-to-day work.

Storage

Caterpillar Global Mining Europe GmbH, Lünen 2012

E

Storing the equipment corrosion protection

Components coated with temporary anticorrosive are protected for around six months.

avoid direct exposure to sunlight

Protect the equipment against direct exposure to sunlight.

Only store the electrical equipment, electronic components, replacement parts made out of rubber or plastic such as seals and hoses as well as hydraulic fluids in closed rooms at 15 ºC to 25 ºC.

moisture and dirt

Protect all parts of the equipment stored outdoors against moisture and dirt, e.g. using tarpaulins.

The mounting surfaces of hydraulic components must be protected against corrosion and sealed with blind plates. Protect the hydraulic plug connectors and the connectors of the electrical cables with the caps and plugs supplied.

short term storage

long term storage

During short-term storage (approx. 4 weeks) of equipment outdoors, but at temperatures above freezing, electrical components need not be removed. Such components must be particularly protected against excessive temperatures, dirt and moisture.

During long-term storage (more than 4 weeks), the equipment must not be stored outdoors. It must be stored in a dry, well ventilated room.

After a storage period of approx. two years, a random sample inspection must be performed to determine whether the measures taken and the method of storage has prevented damage.

The inspection can be carried out by DBT on request.

natural ageing

Even with proper storage, seals and hoses are subject to natural ageing. A storage period of approx. two years is therefore quoted as an indicative value for these parts.

Important!

Ensure when storing that any new supplies are stored separately from existing stocks in such a way that on removal, old stocks are always taken first.

frost protection for the oil cooler

Doc. no.: 9145 010 000 BA 00

Before storing gearboxes with oil coolers at ambient temperatures below the freezing point, flush out the oil cooler with antifreeze.

EM015401-0 (EN-US)

Storage Gearbox preservation When the gearbox is to be stored for a long period, its interior must be specially preserved. Preserving only especially corrosion-sensitive, bright exterior surfaces such as shaft extensions, flanges, etc. is insufficient.

We recommend the following preservative: TECTYL 511-M by VALVOLINE The following steps must be carried out to preserve the interior of the gearbox: The gear oil must be completely drained, even small pools and drops of oil residue must be avoided because they hinder anticorrosives. The gearbox may need to be swivelled or turned to the side.

Remove the breather plug so that it is not adversely affected by the preservative.

Allow the gearbox to run for at least 15 min without load so that it becomes thoroughly coated.

Drain the preservative as thoroughly as possible. Do not allow small pools of liquid to form in the process.

Vent the gearbox thoroughly for at least 24 hours with the inspection hole cover open as the preservative contains a solvent (petroleum spirit) that must be allowed to evaporate.

Danger!

Solvent flashpoint (petroleum spirit) 40 ºC according to DIN 51 755. Hazard class A II according to VbF (Ordinance for flammable liquids) The flammable solvent is heavier than air. The opening should be if possible at the bottom on the lower side so that the solvent evaporate out of the bottom. The gearbox may need to be swivelled or turned to the side.

After receiving the anticorrosion treatment mentioned above, the gearbox can be stored underneath a roof without additional packaging for nine months.

It should be stored so that vents and other openings are covered to prevent water from penetrating the interior of the gearbox.

The measures to prevent the water from penetrating should not adversely affect the inner ventilation of the gearbox.

Preserved gearboxes must be marked with information on the anticorrosive, date of preservation and storage period.

Bright exterior flanges such as shaft extensions, flanges, etc. should be coated with a non-slippery wax film or wax tape.

When the gearbox is started up, the preservative in the gear oil dissolve. It can remain in the gearbox until the next oil change without adversely affecting the ability of the oil to lubricate.

3.4

Gearbox K-10 / K-10.1

Caterpillar Global Mining Europe GmbH, Lünen 2012

Caution!

The operating temperature of the preservative must be at least 18 ºC to 20 ºC. Observe VALVOLINE's instructions

E

Then completely fill the gearbox with preservative. The required quantity equals the volume of the interior of the gearbox (see section “General technical data”). The yield 35 to 45 m2/l.

EM015401-0 (EN-US)

Transport Preservatives must be removed from the breather plug before start up if required. Gasoline, paraffin, diesel oil, wax remover or basic media can be used to do this.

Filters that are part of the gear oil circuit must be monitored regularly for the first months after commissioning.

Transport Load units; dimensions and weights It is imperative that you observe the transport sheets. They include information on: Dimensions Weight Lifting points and Centers of gravity.

Caterpillar Global Mining Europe GmbH, Lünen 2012

E

Where technically possible, the load units have suitable lifting points for transport and erection.

Warning!

Use only load handling devices complying with the technical and legal regulations for transporting loads.

You could be seriously injured or even killed by falling loads.

Use only suitable load handling devices.

Transport of equipment at temperatures between -21 ºC and -40 ºC is only permissible when certain measures were taken to meet these conditions at the design and manufacturing stages. Nevertheless, the individual parts and devices of this equipment must not be subjected to sudden impact loads at such low temperatures and may only be loaded statically or quasi-statically.

During transport of this equipment with floor conveying devices at such low temperatures, measures must also be taken to ensure that the parts and devices are not subjected to sudden impact loads.

At very low temperatures and on poor roads, the transport vehicle speed must therefore be limited to max. 25 km/h for truck transport.

frost protection for the oil cooler

Before transporting gearboxes with oil coolers at ambient temperatures below the freezing point, flush out the oil cooler with antifreeze.

electrical and electronic components

Electrical and electronic components must be removed for overseas transport or prolonged storage outdoors, unless these components or the complete equipment is protected against harmful environmental influences by suitable packaging.

The electrical cables remain in the equipment. They must be carefully protected against transport damage and soiling of the connections.

Gearbox installation Electric motors Flange position “W” For e-motors, flange position “W” describes the distance from the motor flange to the shaft collar. For the drive connection assembly, it is the distance from the contact surface of the protection cover (motor side) to the contact surface of the elastic coupling.

Caution!

If the flange position “W” at the electric motor is larger than at the drive connection, the motor shaft and gearbox drive shaft bearings will be strained. This can result in damage to the gearbox and the electric motor!

Flange position “W” on e-motor

Pay particular attention to the following instructions before installing the e-motor: The exact flange position “W” of the electric motor must be measured before installation.

If the flange position “W” of the electric motor is larger than that of the drive connection assembly, one component of the drive connection assembly (e.g. hub of the flexible coupling) must be shortened accordingly.

The connecting pieces have to be installed using the mounting and pulling-off device.

Installing the electric motor Clean the shaft of the E-motor and apply molybdenum disulfide.

Pull the motor side coupling half of the plug-in coupling (coupling hub) onto the motor shaft. Flange the e-motor onto the protection cover and guide the coupling hub into the rubber tappet of the coupling flange. Make sure that the flange connection fits firmly and is centered perfectly.

Caution!

Blows to the motor shaft and gearbox shaft will damage the shaft bearings. Therefore always use a mounting and pullingoff device for installation and removal of the connecting pieces.

Please make sure you observe the instructions in the E-motor's separate operating manual.

Caution!

Only install electric motors with performance specifications (torque, speed) permissible for the gearbox (see Chapter 6 “Technical data”).

If you prefer to install electric motors other than those approved by us, please contact our service department in advance.

Caution!

Be sure to observe the relevant instructions on starting up in the separate operating manuals of the complete conveyor installation.

Errors during start-up can result in serious machine damage and thus high repair costs.

Carefully read all the operating manuals on the conveyor installation!

Before start-up The following work has to be performed on the gearbox before beginning with the actual start-up: checking the oil level

Caterpillar Global Mining Europe GmbH, Lünen 2012

E

In any case, before starting up the gearbox you have to control the oil level of the gearbox! The gearbox is supplied without oil filling!

The K-10 gearbox has two oil chambers. The oil chambers ”main gearbox” and ”input shaft bearing assembly” must be filled with oil separately.

The K-10.1 gearbox has one oil chamber.

Remove the oil dipstick and fill oil into the respective bore. Make sure that the magnetic rod and the screw plug have been fitted and tightened.

Caution!

The oil levels required depend on the inclination of the gearbox. A plate attached to the gearbox indicates the corresponding oil level mark for the various angles of inclination (see ”Oil levels and oil capacities” in section ”Technical data”).

Fill oil into the respective oil chamber until the oil dipstick reading gives the applicable oil level.

Too little oil is detrimental to the lubrication of the gears and rolling contact bearings. Too much oil results in large losses due to splashing, to oil foam formation and increased heat generation. inspection of the gearbox Check to make sure that the K-10 gearbox has the two breather plugs fitted ( ”main gearbox” and ”input shaft bearing assembly” oil chambers). The K-10.1 gearbox has one breather plug.

Gearbox maintenance Changing the oil The oil of a new or completely rebuilt gearbox must be changed for the first time after 300 operating hours. After this, the gearbox should be thoroughly cleaned and filled with fresh oil after every 2,000 operating hours - but at least semi-annually.

Important!

The oil must be changed when the gearbox is at operating temperature so that the warm, thin oil can wash away the oil sludge more effectively.

Oil is drained via the screw plug bore. Its location is illustrated in Chapter 6, section “Main dimensions”.

A premature oil change is required if: The level of contamination has reached the value of 0.1% foreign parts.

Determine the neutralization number according DIN 51 558 water content according to DIN 51 582 percentage of foreign substances according to DIN 51 592 sulfate ash according to DIN 51 575

Lubricating the gearbox The labyrinth channels on the shearing head and on the chain sprocket (dependent on type gearbox) must be lubricated daily with grease A1 (see Chapter 6, section “Lubricating greases and pastes”). Press grease into the lubricating nipples until fresh grease emerges at the sealing gap.

The location of the lubrication nipple is illustrated in Chapter 6, section “Main dimensions and connections “.

Checking the breather plug On a weekly basis check that the breather plug is functioning properly and replace if necessary.

Remove the breather plug at operating temperature. If air escapes, the breather plug is defective and has to be replaced.

Notice!

Replace a defective breather plug with a new filter only. Do not try to clean the old filter.

Used breather plugs may not be reused. Dispose of them in an environmentally-friendly manner.

Technical description Technical description Gearbox K-10 is intended to be installed on the drive frame with a separate shaft. The output shaft can alternatively be equipped with internal toothing N 190 or with a splined shaft W 160.

The K-10.1 gearbox is equipped with a splined shaft W 160.

The motor and the gearbox are connected by a flexible shaft coupling or by a fluid coupling with flexible shaft coupling. design

The gearbox consists of a bevel gear input stage and two spur gear stages. The housing is divided into two.

The gearbox can be used in a right-handed or left-handed version simply by relocating the dipsticks and the breather plugs.

lubrication

The gears and roller bearings are lubricated by oiling. There is a second separate oil chamber in the area of the drive shaft bearings.

This enables perfect lubrication when the gearbox is on an incline especially when the drive shaft is elevated. Both oil chambers are equipped with a dipstick and a breather plug.

Caterpillar Global Mining Europe GmbH, Lünen 2012

E

Defined oil levels must be complied with depending on the inclination of the gearbox. A sign on the gearbox or the table in section “Oil levels and oil quantities” specifies the oil level mark line that applies to the respective inclined position.

The K-10 gearbox has got two oil chambers and accordingly two oil dipsticks.

The K-10.1 gearbox has one oil chamber and one oil dipstick. In order to ensure proper lubrication the maximum permissible angles of inclination must not be exceeded.

Caution!

In order to ensure proper lubrication the maximum permissible angles of inclination for the gearbox K-10.1 of ± 5° must not be exceeded. lubricating nipple

Labyrinth channels on the shearing head and on the chain sprocket have to be lubricated via lubricating nipples.

cooling

The gearbox may be operated without oil cooler upto a drive output of 160 kW. For drive outputs of >160 KW, any heat generated must be dissipated by an oil cooler (see Fig. 17).

water cooling

Notice!

The gearbox can overheat and can be badly damaged if the continuous power exceeds 160 kW. Therefore, for continuous power more than 160 kW a water cooling is necessary.

The cooling water input temperature of 25 ºC must not be exceeded. The quantity of cooling water is approx. 5 l/min. The cooler is protected against overpressure by a pressure relief valve set to 30 bar.

Permissible media Gear oil requirements Choosing the correct gear oil and carefully monitoring lubrication are important prerequisites for trouble-free operation. These factors also contribute to prolonging the service life of the gearbox.

Load-bearing capacity For mechanically testing gear oil according to DIN 51354, sudden changes in the upper wear profiles in all 12 power levels are not permitted in the GRC normal test A/8, 3/90 and the GRC special test A/16, 6/120. This means that the critical power level must be above 12.

In addition, the “specific change in weight” of the test gears ms (specific wear) may not exceed 0.27 mg/kWh. Ageing resistance The gear oil must possess outstanding “thermostability” and “ageing resistance” for the oil changing interval after 2000 hours of operation.

The greases listed in the same table can be mixed. Other products may only be used if the supplier can guarantee that they are equivalent. Differently composed lubricating greases must not be mixed as this may change the consistency, i.e. the mixture can become thinner so that the lubrication effect is not sufficient.

It may also be dangerous to use lubricating greases that have the same saponification base but different origins. When in doubt, the manufacturer of the lubricating grease to be used should be contacted to confirm the compatibility of the grease in question.
