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

The invention provides a spiral gear machining mechanism with a workpiece bearing shaft provided with two annular protrusions. The spiral gear machining mechanism is used for machining a blank (85) and comprises a base (3), a rotary inner thread piece (1), an outer thread piece (2) and the cylindrical workpiece bearing shaft (8). The rotary inner thread piece (1) comprises an upper cylinder portion (11) and a lower cavity portion (12). The lower cavity portion (12) is connected with the base (3) through a bearing device (13) in a peripherally rotating and axially fixed mode. The outer thread piece (2) is cylindrical. The outer peripheral surface of the outer thread piece (2) is provided with outer threads jointed with inner threads in the upper cylinder portion (11). The base (3) is internally provided with a cavity (31), and the cavity (31) is provided with a top wall (32).

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...
