Question

For the same pitch, which of the following statement is true?

(a) Cycloidal gears are stronger than involute gears

(b) Involute gears are stronger than cycloidal gears

(c) Both cycloidal and Involute gears have equal strength

(d) Cycloidal gears are stronger for lower pitch only

This question was addressed to me in exam.

The query is from Interference topic in chapter Toothed Gearing & Gear Trains of Machine Kinematics

Answer 1

Correct choice is (a) Cycloidal gears are stronger than involute gears

The explanation is: Cycloidal teeth have wider flanks, as a consequence the cycloidal gears are stronger than the involute gears, provided the pitch is the same. That is why cycloidal gears are used for cast teeth.
