Compound Gear Train
When a series of gears are connected in such a way that two or more gears rotate about an axis with the same angular velocity, it is known as compound gear train.
Reverted Gear Train
If the axes of the first and last wheel of a gear coincide it is called reverted gear train. Such arrangement is used in clocks and in simple lathe, where ‘back gear’ is used to give slow speed to the chuck.
Epicyclic Gear Train
- When there exists a relative motion of axes in a gear train, it is called an epicyclic gear train. Thus in an epicyclic train, the axis of at least one of the gears also moves relative to the frame.
- If arm ‘a’ is fixed. Turn ‘s’ through x revolutions in the clockwise direction. Assuming clockwise motion of a wheel as positive and counter clockwise motion as negative. Revolution made by ‘a’ = 0; Revolution made by ‘s’ = x
