Abstract

A spiral gear machining mechanism capable of flexibly limiting vertical motion is used for machining a blank (85) and comprises a base (3), a rotatable internal thread part (1), an external thread part (2) and a cylindrical workpiece bearing part (8). The rotatable internal thread part (1) comprises an upper cylinder part (11) and a lower chamber part (12), the lower chamber part (12) is connected with the base (3) through a bearing device (13) in the mode that the lower chamber part (12) can be rotated in the circumferential direction and fixed in the axial direction, the external thread part (2) is cylindrical, an external thread is arranged on the outer circumferential face of the external thread part (2) and connected with an internal thread in the upper cylinder part (11), a cavity (31) is formed in the base (3) and provided with 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...
