Abstract

The invention discloses a coaxial planetary transmission multi-gear variable speed transmission mechanism. It has one input terminal and one output terminal. It comprises an input shaft, clutches, a brake, an output shaft, and a planetary transmission mechanism composed of a sun gear, a planetary gear, a planetary frame and a gear ring. There are multiple clutches corresponding to a plurality of gears. Each clutch is connected to an independent planetary transmission mechanism. The sun gears, input shafts and output shafts of a plurality of planetary transmission mechanisms are arranged on the same axis. The input shafts are connected to the primary sun gears of the planetary transmission mechanisms in different gears via the clutches. The primary sun gear of each planetary transmission mechanism is connected to the brake I. The last stage planetary frame of the planetary transmission mechanism is connected to the gear ring through the last stage planetary gear. The last stage planetary frame is connected to the gear II, and the gear ring is connected to the input shaft. The mechanism not only can realize the multi gear shifts of the coaxial planetary transmission, but also can realize different transmissions which have very different gear transmission ratios. Moreover, the speed will not become too high along with the driving gear and will not affect the normal driving.

Description

Technical field [0001] The invention relates to the field of speed reducers, in particular to a coaxial planetary transmission multi-speed speed change transmission mechanism. Background technique [0002] Planetary transmission is widely used in many fields. At present, there is no coaxial multi-stage planetary transmission mechanism on the market, and it is necessary to realize the shift of the planetary mechanism, especially the gear shift of the multi-speed, large transmission ratio reducer. Shift transmission mechanism that affects normal driving. Summary of the invention [0003] The purpose of the present invention is to solve the above-mentioned technical problems and provide a coaxial planetary transmission multi-speed transmission mechanism, which can not only realize the multi-speed transmission of the coaxial planetary transmission, but also realize the difference in the transmission ratio of different gears. Different transmission, and the speed of the driven gear wi...
