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 relates to a spiral gear machining mechanism capable of quickly radiating heat, which is used for machining a blank (85). The spiral gear machining mechanism capable of quickly radiating heat comprises a base (3), a rotatable internal threaded piece (1), an external threaded piece (2) and a cylindrical workpiece bearing piece (8), wherein the rotatable internal threaded piece (1) comprises an upper cylindrical portion (11) and a lower chamber portion (12), the lower chamber portion (12) is connected with the base (3) through a bearing device 13) in a circumferentially rotatable and axial fixed manner, the external threaded piece (2) is cylindrical, external threads are arranged on the external circumferential surface of the external threaded piece (2) and are jointed with internal threads in the upper cylindrical portion (11), and a cavity (31) is formed in the base (3), the cavity (31) has a top wall (32) and a driving motor (4) is installed in the 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...
