Description

technical field

[0001] The invention relates to the field of gear processing, in particular to the processing of helical gears. Background technique

[0002] The helical gear has the advantages of good meshing, stable transmission and low noise. Moreover, the overlapping ratio is large, which reduces the load of each pair of gears and improves the bearing capacity of the gears. And the minimum number of teeth without undercutting is small. Because the meshing surface is small-large-small, the meshing is smooth, the impact is small, and the noise is low; therefore, it has a large load-carrying capacity, which can improve the life and stability of the gear; and it is small in size. The helical gear transmission is composed of two helical gears meshing together. The purpose is to transmit the movement between two phases of space. However, the manufacture of helical gears is cumbersome, and it is difficult to guarantee the shape and position accuracy of the processed tooth g...
