Question 56
PINAT2 marksNeeds review
A custom pinion, with a width equal to 10 times the module, has 20 full depth teeth and a pressure angle of 20° is being designed. It should transmit a torque of 95 N-m to a corresponding spur gear.
Considering the safe bending stress to be 180 MPa and form factor to be 0.32, the module of the pinion is _____ mm (rounded off to one decimal place).
Note: The Lewis equation gives the tangential force as
, where
is the safe bending stress,
the width,
the form factor, and
the module.Log in to check the answer
