Abstract

The invention discloses a spiral gear processing mechanism with an adjustable processing speed. The spiral gear processing mechanism is used when a blank (85) is processed, and comprises a base (3), a rotatable internal thread element (1), an external thread element (2) and a cylindrical work-piece bearing element (8), wherein the rotatable internal thread element (1) comprises an upper cylinder section (11) and a lower chamber section (12); the lower chamber section (12) and the base (3) can circumferentially rotate and axially fixedly connected through a bearing device (13); the external thread element (2) is in a cylindrical shape; external threads are arranged at the outer circumference surface and are jointed with internal threads in the upper cylinder section (11); a hollow cavity (31) is formed in the base (3), and is provided with a top wall (32); a drive motor (4) is arranged in the hollow cavity (31).

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...
