Problems with spur gears and max addendum

  • #1

Homework Statement


Consider a gear set with the following attributes:


• A pinion base radius of 11mm
• A centre distance of 73mm
• A pressure angle of 24 degrees
• A module of 5.8mm
What is the maximum addendum radius (mm) that the pinion can have to avoid interference?



Homework Equations



ramax=√rb2+c2*sin(θ)2

ramax= maximum noninterfering addendum circle radius of pinion gear
rb= base circle radius of the same member
c= center distance
θ=pressure angle


The Attempt at a Solution


ramax=√rb2+c2*sin(θ)2
ramax=√0.0112+0.0732*sin(24)2
ramax= 0.0316mm

So that is the answer that I got but I was not sure if you need to use the module for anything or whether it is just extra info
cheers
