LEARNING EXPERIENCE Décimo C
We decided to apply the gear assembly mechanic principle in the construction of a windmill.
How gears work? A gear is a kind of wheel which is serrated
The gear let to the machine to produce movement
In the movement that each gear do we can observe how each tooth is engaging and another disengaging
Also the size of each gear would affect the speed between the input and output. The first one is the one with the movement and the second one is the one that “drives” it.
Does the size affects?
The bigger the gear
The smaller the gear
the slower the system’s speed would be
the faster the system would move
Types of gears On the Basis of Arrangement of Shafts of
On the Basis of the Types of Gearing
On the Basis of the Position of Teeth on the Gear. Straight
NonIntersecting and NonParallel
Rack and Pinion
THE MODEL WE BASED ON
HOW IT ENDED LOOKING UP
Our robot was made with LEGO pieces. It was conformed for five gears (four in vertical and one in horizontal) that were hold by nine large pieces and three sticks. This was made with the purpose of function as a windmill. EDISON was programmed with a simple sequence were it just have to do a SINGLE DRIVE for 60 second, and then, it will stop.
DOES IT WORKS?
This work is a combination of the knowledge of machines and mechanisms applied on EDISON.
