Abstract

The invention relates to the technical field of mechanical transmission, in particular to a multistage speed changing device. The multistage speed changing device comprises a power input shaft, a middle transmission body and a power output shaft, wherein a driving stepped gear is arranged on the power input shaft, a driven stepped gear matched with the driving stepped gear is arranged on the power output shaft, and one driving gear in the driving stepped gear is in meshing transmission with one corresponding driven gear in the driven stepped gear through the middle transmission body. The middle transmission body comprises a transmission shaft capable of radially moving, wherein a transmission gear is fixedly connected onto the transmission shaft, and the axes of the power input shaft, the transmission shaft and the power output shaft are parallel. The multistage speed changing device is simple in structure, stable in transmission and convenient to control.

Description

technical field

[0001] The invention relates to the technical field of mechanical transmission, in particular to a multi-stage transmission mechanism. Background technique

[0002] At present, various gear transmission mechanisms and devices generally use gears to move along their axial direction to realize the meshing and separation of gears, so as to realize the adjustment of different transmission ratios. The gear transmission device with the above structure has the defects of complicated structure, inconvenient operation, large volume and high cost.

[0003] The multi-stage transmission mechanism can also adopt a planetary gear structure. Most planetary gear structures use the actuator to make the planetary gears in different meshing states to obtain different transmission ratios. The structure of the planetary gears used to achieve the above purpose needs to be multi- Composed of a planetary row and many shift actuators, the structure of the transmission mechanis...
