The grinding principle of conical involute gears on NC conical wheel gear grinding machine

The greatest possibility of the conical involute gear is in place of bevel gears. The key point, however, is to develop finishing process of conical involute gears which have a comparatively large cone angle and helix angle. In the study, based on the analysis of generating the gear by generating rack, first the grinding principle of conical involute gears is NC conical wheel gear grinding machine is studied. Second, the calculation formulas for machine tool adjustment parameters are deducted and a set of grinding method suitable for conical involve gears is presented. Finally, grinding test and tooth bearing tests are performed. Measurement of the tooth surface verifies that in good agreement with the theoretical ones. This fact proves that this processing method has the applicability.
