英文摘要：

A method of tooth grinding for double crowned face gear with helical pinion machined by using grinding disk was studied in order to manufacture highly precise hardened face gear with helical pinion and obtain parabolic transmission errors and improve meshing performances. The surface of grinding disk with mismatched involute was designed ; the generation theory of helical face gear abraded by grinding disk is analyzed, deducing the tooth surface equation of double crowned face gear with helical pinion based on the generation theory, the grinding disk with mis- match involute and modification of the grinder movement. A tooth surface calculation and contact analysis example of double crowned face gear with helical pinion was represented and the results show that the maximum error of the theoretical tooth surface of face gear is 5.98 ~ 10 -4/zm, the grinding and crowning method is feasible and the para- bolic transmission is obtained, avoiding edge contact and approving m
