Problems solved by technology
[0002] The hydraulic planetary reducer is used to connect between the prime mover and the working machine or the actuator, mainly to match the speed and transmit the torque. The brake is built-in and installed between the hydraulic motor and the planetary reducer. The heat dissipation performance of this structure is poor , the heat cannot be dissipated in time when braking, which will easily cause aging or even damage to the components. When the brake fails and the brake pads are replaced, the hydraulic motor needs to be disassembled together. It is very inconvenient to repair and replace parts.

The invention discloses a hydraulic drive planetary gear with an externally-mounted brake. The hydraulic drive planetary gear comprises a planetary gear body and a hydraulic motor, the hydraulic motor and the planetary gear body are vertically arranged, a driving shaft of the hydraulic motor penetrates the planetary gear body to extend out from the other end, and the driving shaft extends out of the other end of the planetary gear body to be provided with a brake wheel. The hydraulic drive planetary gear with the externally-mounted brake has the beneficial effects that the brake wheel and the hydraulic motor are coaxially installed on the two sides of the planetary gear body, so that the radiating performance of the brake hydraulic drive planetary gear with the externally-mounted brake is greatly improved; and meanwhile, the hydraulic drive planetary gear has the beneficial effects that the brake can be conveniently replaced and detected.
Description
technical field [0001] The invention relates to a reducer, in particular to a hydraulic planetary reducer. Background technique [0002] The hydraulic planetary reducer is used to connect between the prime mover and the working machine or the actuator, mainly to match the speed and transmit the torque. The brake is built-in and installed between the hydraulic motor and the planetary reducer. The heat dissipation performance of this structure is poor , The heat cannot be dissipated in time during braking, which can easily cause aging or even damage of parts. When the brake breaks down and the brake pads need to be disassembled together, it is very inconvenient to overhaul and replace parts. Contents of the invention [0003] The purpose of the present invention is to provide an external brake hydraulically driven planetary reducer. [0004] The technical solution of the present invention is an external braking hydraulically driven planetary reducer, including a planetary r...
