Problems solved by technology
[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, such as At present, the gear shifting devices on ships, vehicles and other transportation machinery all use the above-mentioned gear shifting device. The above-mentioned device has the defects of complex structure, inconvenient operation, large volume and high cost.
[0003]Multi-stage transmission mechanism can also adopt planetary gear structure, most planetary gear structures use actuators to make planetary gears in different meshing states to obtain different transmission ratios, The structure of the planetary gear used to achieve the above purpose needs to be composed of multiple planetary rows and numerous shift actuators, which makes the structure of the transmission mechanism complicated and requires high technical requirements for manufacturing and maintenance. This is the deficiency of the existing technology.
