Formula for Transverse Backlash
Formula for Transverse Backlash
(OP)
What is the formula to determine transverse backlash in helical gears?
I have an old paper but I can't read it and I can't find the formula on the internet.
So far I have: Bt=Bn/cos(pressure ang)
However, I believe I am missing one other variable.

RE: Formula for Transverse Backlash
Bt=Bn/(cos(alpha)*cos(beta))
Br=Bn/(2* sin(alpha)*cos(beta))
Where Bt = circumferential backlash
Br = radial backlash (just for info)
Bn = normal backlash
alpha = operating transverse pressure angle
beta = Base helix angle
Hope that helps
