For the double reduction gear if the input speed is 1920 rpm

For the double reduction gear, if the input speed is 1920 rpm in clockwise direction, what is the output speed?

Solution

Inorder to calculate the output speed, we should know the number of teeth of the gear train.

If w know the teeth then the output speed can be calculated as

Assume there are 5 gears with an idler,

N5 = (T4/T5) X ( T3/T4) X ( T1/T2) X N1
