DIN tolerances for fine spur gear of module < 1 mm?
Hi everybody, As you know, DIN 3961 gives tolerances for gear of module>=1. It refers to DIN 58405 for fine gears of module<1. But, as I know, DIN 58405 has been withdrawn!! So: 1-For fine gear of module < 1; which DIN standard is applicable? 2-For gear of module>=1, both DIN 58405 and DIN 3961...- sabaa

problem with maximum tooth thickness suggested by AGMA 2002?
Thanks to gearcutter and tbuelna. The other data of gears are center distance: a=(Zp+Zg)*m/2=95.25(-0.01 to +0.01) tip diameters: do_p=Zp*m+2*m=51(-.02 to -0.05) , do_p=145.5(-.02 to -0.05) root diameter (in theory, not checked): df_p=Zp*m-2.5*m=44.25, df_G=138.75 So the theoretical clearance of...- sabaa

problem with maximum tooth thickness suggested by AGMA 2002?
Hi everybody! I have a problem with maximum tooth thickness suggested by AGMA 2002. As a practical experience, I determined maximum tooth thickness of a pair of gear using that standard. Unexpectedly, after fabrication, many of gear meshing had interference and didn't rotate properly. However...- sabaa
