Please see Page 165 for more details.② The backlash values shown in the table are the theoretical values for the backlash in the normal direction of a pair of identical gears in mesh.③ These gears produce axial thrust forces. See Page 167 for more details.④ Right handed and left handed helical gears in the same module are designed to mesh as a pair, but SH gears are not interchangeable with KHG type helical gears.*Above is for illustration purposes only and differs from actual tooth forms.
