Problems solved by technology

Among them, frequency conversion speed regulation is electronic speed regulation, which has high environmental requirements, and the cost is relatively high in high-power (MW level) transmission systems. Liquid couple speed regulation is hydraulic speed regulation, permanent magnet speed regulation and planetary gear speed regulation. Similar, both belong to transmission system speed regulation, hydraulic speed regulation and permanent magnet speed regulation are stepless speed regulation systems, but there is slip loss, planetary gear speed regulation is stepped speed regulation, and the speed regulation range is limited

Abstract

The invention discloses a high-power energy-saving speed adjustment system for a three-endpoint cylindrical planetary gear. The speed adjustment system comprises a driving end system (1), a three-endpoint cylindrical planetary gear system (2) and an output end system (3); and the driving end system (1) is connected with the output end system (3) through the three-endpoint cylindrical planetary gear system (2). According to the speed adjustment system, with adoption of the structure, the working state of an auxiliary input end system is adjusted, so that the torque of an outer differential gearis adjusted, and the energy output of a load system is adjusted; a stepless speed adjustment mechanism which is free of slip loss and is located on a transmission system is provided by the aid of thestructure; the acceleration adjustment purpose is achieved, and deceleration adjustment and overload operation capability of the system can also be realized in particular cases; the load quick-braking function can be realized; and the alternate function in the breakdown state of a driving motor can also be realized.
