Question

The interface or undercutting in involute gears can be avoided by

A.

Varying the centre distance by changing pressure angle

B.

Using modified involute or composite system

C.

Using modified involute or composite system

D.

All options are correct

Answer ( Option D)

All options are correct

Solution

If contact portions of tooth profiles of meshing gears are not involute, then the gears do not execute conjugate action that is why the output gear will not have constant angular velocity. This is called interference.

Interference can be avoided by :

1. Increasing slightly the center distance between the meshing gears or by using profile shifted gears.

2.Using a pinion with longer than the standard addendum and the mating gear with shorter than the standard addendum.

3.By increasing pressure angle.

4.By increasing the number of teeth on gears.

Hence, the correct option is (D).
