Description

Technical field [0001] The invention relates to the field of gear processing, in particular to the processing of helical gears. Background technique [0002] Helical gears have the advantages of good meshing, smooth transmission and low noise. Moreover, its large degree of coincidence reduces the load of each pair of gears and improves the carrying capacity of the gears. And the minimum number of teeth that do not produce undercut is small. Because its meshing surface is small-large-small, meshing is stable, impact is small, and noise is low; therefore, it has a large load-bearing capacity, can improve the life and stability of the gear, and is small. Helical gear transmission is composed of two helical gears meshing together. The purpose is to transfer the movement between two phase-shifted axes in space. However, the manufacture of helical gears is troublesome, and it is difficult to guarantee the accuracy of the processed cogging. [0003] In particular, in some specific ap...
