近年来，超出国内伞齿轮机床加工范围（41600mm）的也形加工越来越多。如何在现有的条件下顺利加工出大型伞齿轮齿形，探索出切实可行的工艺方法以满足市场的需要势在必行。1措施大型伞齿轮的齿形加工可采用两种工艺方案：（l依模床上简易加工方法；（2）在插齿机上配合动力头
In recent years, more than domestic bevel gear machine processing range (41600mm) is also shaped processing more and more. How to smooth out the large bevel gear tooth shape under the existing conditions and explore practical process methods to meet the needs of the market is imperative. 1 measure large bevel gear tooth profile processing can be used two kinds of process options: (l by simple bed processing method; (2) gear shaper with the power head
