6.Assembly of the Motor

[1]Precautions for the assembly of the motor

Read the following precautions carefully prior to start assembling the motor.

1. When starting the assembly operation, be sure to wear safety shoes and other protective gear. 2. When assembling the motor, use the specified tools. 3. In order to prevent injuries during the disassembly work, prepare a stable workbench that is about waist height, and perform the disassembly on the workbench. 4. The motor is comprised of precision components. As such, any attachment of foreign matter must be avoided. Assemble the motor in a dust-free room to prevent the components from becoming contaminated with soil or dust. 5. The motor is comprised of precision components. Any denting or damaging of its surface must be avoided.

While handling motor components in the assembly process, be fully attentive not to dent or damage them. 6. Be sure to repair all damage detected in the disassembly process. Prepare all replacement parts needed beforehand, and then start assembling. 7. Remove metal chips and foreign matter from all parts and check that all parts are free from burrs and indentations before starting the assembling procedure. When detecting burrs or indentations, provide remedies by using a whetstone. 8. In the assembling procedure, apply clean hydraulic oil on respective sliding sections and rolling sections prior to the assembly work. 9. Fully degrease sections where a screw lock agent and liquid packing are applied and remove water prior to the assembly work. 10.Replace O-rings, backup rings and other sealing parts with new ones. 11.In the assembling procedure, take care not to allow O-rings and backup rings to be damaged. When assembling O-rings and backup rings, apply a small amount of grease before assembling. 12.When assembling, it is helpful to use vaseline, grease, etc., to prevent fall of parts involved. 13.Tighten bolts up to the torque specifications shown in Table 4 in Chapter 5, section 2 in the respective joins. Control tightening torque using a torque wrench. 14.After completing the assembly, stop all ports in order to block dust intrusion into the inside of the motor.

[2]Assembling procedure

Follow the procedure below to assemble the motor, observing the precautions given in section 1.

1.)Assembly of reduction gear section 1.)Assembling the floating seal (2) onto the flange (1-1)

Check the following points for the floating seal (2), and then assemble the floating seal (2) onto the flange (1-1), using a floating seal assembly jig.

Confirmation:

a.Check that the mounting surface of the floating seal (2) on the flange (1-1) is free from soil or dust. b.Fully degrease the mounting surface of the floating seal (2) on the flange (1-1). c.Check that the surface of the O-ring of the floating seal (2) is free from soil or dust. d.Fully degrease the surface of the O-ring of the floating seal (2).

2.)Assembly of the angular bearing (3) onto the housing (4)

Press fit the angular bearing (3) onto the housing (4), using a press-fit jig and a press.

3.)Assembly of the angular bearing (2) onto the housing (4)

Check the following points for the floating seal (2), and then assemble the floating seal (2) onto the housing (4), using a floating seal assembly jig.

Confirmation:

a.Check that the mounting surface of the floating seal (2) on the housing (4) is free from soil or dust. b.Fully degrease the mounting surface of the floating seal (2) on the housing (4). c.Check that the surface of the O-ring of the floating seal (2) is free from soil or dust. d.Fully degrease the surface of the O-ring of the floating seal (2).
