A driving device with the function of buffering energy consumption

Abstract

The invention provides a driving device with an energy consumption buffering function. The driving device comprises a high-speed-level part, an energy-consumption buffering part and a low-speed-level part which are connected with one another. A motor M1 is sequentially connected with a first gear pair, a second gear pair, a one-way transmission mechanism, a first NGW planet gear train in series to form the high-speed-level part. A third gear pair, a spring mechanism, a fourth gear pair, an NGW planet differential gear train and a damper form the energy-consumption buffering part. A second NGW planet gear train and a fifth gear pair form the low-speed-level part. The driving device has the speed reducing function with the low speed level in positive transmission (from the motor to the tail end) and has the speed increasing function with the low speed level in negative transmission (from the tail end to the spring mechanism). The driving device has the low-rotating-speed and large-torque output function, the overload protection function, the negative transmission clamping function and the negative transmission energy consumption buffering function and has the advantages of being small in size, light and high in efficiency and reliability.

Description

technical field [0001] The invention relates to a driving device, in particular to a driving device with the function of buffering energy consumption. Background technique [0002] my country's manned spaceflight project is divided into three steps: out-of-vehicle activities, rendezvous and docking, and space stations. The third step is to establish a long-term in-orbit space station. Due to the problem of transportation capacity, large long-term on-orbit space stations need to complete on-orbit components, and the assembly process is completed by space robotic arms; in addition, during the orbital operation of space stations, a large number of extravehicular activities need to be completed, most of which need to be completed by robotic arms . According to the control mode, space manipulators are divided into: closed-loop control manipulators and open-loop control manipulators, among which the closed-loop control manipulators mainly include Canadian manipulators, ESA manipu...
