Description

Technical Field

[0001] The utility model relates to the technical field of tooth clutches, in particular to a tooth clutch. Background Art

[0002] As a common component of mechanical transmission, the tooth clutch can complete the task of power cutting and transmission when there is a speed difference between the active and passive ends. The clutch is used in the clutch of the main drive shaft of the hot stamping plate roller.

[0003] The tooth clutch is easy to disassemble and use, and has the effect of reducing axial stress on the main drive shaft during operation. The conventional angle of the clutch is 40 degrees. After testing, 30 degrees and 20 degrees are more suitable for the use of equipment in different occasions. The tooth clutch used in the prior art will produce a large impact between the teeth of the two end faces when engaged, which is easy to cause tooth surface wear or even tooth root breakage and fall off. Therefore, the engagement can only be completed when the relative speed difference is very small and the transmitted torque is not high, which restricts its scope of use. Utility Model Content

A plurality of limit grooves 11 are provided on the inner plate surface of the telescopic plate 10, and bolts are threadedly connected to the surface of the outer plate of the telescopic plate 10.

[0031] The outer surface of the driven column 9 is provided with a plurality of docking grooves.

[0032] In the utility model, the working steps of the device are as follows:

The passive semi-clutch 5 drives the active semi-clutch 2 to rotate through the engaging teeth 4. When it is necessary to adjust the length of the driven column 9, the bolt is first disengaged from the inside of the limiting groove 11 to the outside, and then the driven column 9 is pulled through the telescopic plate 10. The driven column 9 drives the connecting column 8 to slide outward, thereby adjusting the length of the driven column 9.
