Description

Technical Field

[0002] In the field of mechanical transmission, it is a common technical means to use a clutch device to separate two meshing gears to temporarily cut off power transmission. During the short process of cutting off power transmission, the rotation speed of the driven shaft can be changed by allowing the driving gear to mesh with the driven gear of different diameters again, thereby achieving the purpose of acceleration or deceleration. This technology is widely used in machine tools used for production and processing to control the speed of the equipment output end to meet different production needs.

[0003] The clutch device used in the mechanical transmission structure in the prior art usually makes the drive shaft reach the target speed through several levels of speed change, and the drive shaft can usually only transmit power to one shaft, and there is less space for external expansion.
