4.- PULLEYS, GEARS AND BELTS

Rotary motion is one of the most common types of motion in machines because it is the movement created by motors..
Rotary transmision mechanims transfer these motions from the driver shaft to the driven shaft.

In this viedo you can learn the main concepts of these types of mechanims.





ACTIVITIES

1.- Calculate the output speed of a friction wheel transmission system if the first wheel has a diameter os 10 cm, rotates ar 10 rpm and the transmission ratio is 5. Idicate whether the mechanism is a speed reducer and if the second wheel is bigger or smaller.

2.- Study the gear train in the figure. Calculate the output speed of transmission system, given that wheel A rotates at 600 rpm. The number of teeth on each wheel is idicatated in the figure.
