Variable speed winding planetary reducer

Abstract

The invention relates to a variable speed winding planetary reducer. The variable speed winding planetary reducer comprises at least one input shaft, a fixing flange, an output gear ring, a first-stage planetary frame, a first-stage planetary gear, a first-stage sun gear, a second-stage planetary frame, a second-stage sun gear, a second-stage planetary gear, an end cover and a connecting rod; splines and half or complete teeth are arranged at the upper end and the middle part of the connecting rod; the length of the splines and half or complete teeth is equal to the axial moving distance of the connecting rod; the connecting rod is in connection fitting with the input shaft, the first-stage sun gear and the second-stage sun gear; the first-stage planetary gear engages with the output gear ring; the second-stage sun gear is engages with the second-stage planetary gear; the second-stage planetary gear engages with the output gear ring; the second-stage planetary frame is fixedly matched with the first-stage sun gear. The variable speed winding planetary reducer is compact in structure; the connecting rod can axially inwards or outwards move; the rate can be automatically adjusted, so as to change the rated output torque and rotating speed of the reducer.

Description

technical field [0001] The invention relates to a speed reducer, in particular to a variable speed winch planetary speed reducer. Background technique [0002] The reducer generally uses the motor, motor and other high-speed running power as input, and the gear with a small number of teeth on the input end of the reducer meshes with the gear with a large number of teeth on the output end to achieve the purpose of deceleration. The reducer is between the prime mover and the working machine or the actuator. It plays the role of matching speed and transmitting torque. The reducer is a relatively precise machine that can reduce the speed and increase the torque. The planetary reducer is a mechanism that uses the speed conversion of the planetary gear train to convert the speed of the input motor into the required output speed and obtain a larger output torque. In addition to rotating on their own rotating shafts, their rotating shafts also rotate with the planet carrier around ...

But the planetary reducer can only transmit one speed ratio

The traditional planetary reducer requires multiple speed ratios. When reducing speed, it needs to set up multiple reducers. The structure is heavy, the cost is high, and the speed ratio cannot be adjusted by itself.

In addition, in the planetary reducer of the prior art, when the power input to the input end of the reducer is stopped, the reduction mechanism will still operate under the action of the output load and inertia, resulting in malfunction of the mechanism, and even endangering the safety of the device and personal safety
