Why is it so important that you need to know when calculate a bevel gear two (2) different numbers of gear teeth are to be know?

(4 marks)

3 b. Find the indexing on the crank handle to turn an angular displacement of XXXXXXXXXX

See below at end of paper sample solution how to work out question 3b.

To calculate the angular displacement by using:

(i) converting this to a continued fraction and

(8 marks)

(ii) Tabular method to use for displacement.

3a). For a bevel gear all the calculations are based on the number of teeth in the pinion and the gear. The shaft angle, reference cone angles are calculated based on the number of tooths as given below,
Let and be pinion and gear tooth numbers, shaft angle, and reference cone angle and , then:
Generally, a shaft angle is 90 degrees for most cases. Which is called “bevel gear in right...
