Problems solved by technology

However, the manufacture of helical gears is cumbersome, and it is difficult to ensure the accuracy of the shape and position of the processed tooth grooves
[0003] In particular, in some specific application areas, such as soft materials (such as plastics) processing, traditional metal processing methods will be difficult to meet the requirements of reducing costs and improving processing speed and accuracy

Abstract

A spiral gear machining mechanism driven by a motor is used for machining blanks (85). The spiral gear machining mechanism comprises a base (3), a rotary internally threaded piece (1), an externally threaded piece (2) and a cylindrical workpiece bearing piece (8). The rotary internally threaded piece (1) comprises an upper cylinder portion (11) and a lower cavity portion (12). The lower cavity portion (12) can rotate relative to the base (3) in the circumferential direction through a bearing device (13) and can be fixedly connected with the base (3) in the axial direction. The externally threaded piece (2) is cylindrical, and external threads located on the circumferential face of the outer circle of the externally threaded piece (2) are in joint with internal threads located in the upper cylinder portion (11). A drive motor (4) is arranged in the lower cavity portion (12) and located on the upper side of the base (3) and connected with the lower end of a first shaft (5).

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...
