Abstract

The invention provides a hydraulic motor and a pressure regulating device. The hydraulic motor comprises a motor shell, a rotating shaft, a brake shell, a pre-tightening spring cavity, a brake device rear cover and an elastic pressure assembly, wherein a motor liquid inlet and a motor liquid return opening are formed in the motor shell, the rotating shaft penetrates through the motor shell and can rotate relative to the motor shell, a friction plate is fixedly arranged on the rotating shaft, the brake shell is fixed to the rear end of the motor shell and provided with a brake cavity, the rear end of the rotating shaft is inserted into the brake cavity, the friction plate is located in the brake cavity, the pre-tightening spring cavity is fixed to the rear end of the brake shell and provided with a hydraulic medium cavity, a brake device liquid inlet communicating with the hydraulic medium cavity is formed in the pre-tightening spring cavity, the brake device rear cover is fixed at the rear end of the pre-tightening spring cavity, and the elastic pressure assembly is arranged in the hydraulic medium cavity and used for pressing the friction plate so as to enable the rotating shaft to stop rotating. The hydraulic motor is good and stable in braking effect.

Description

technical field [0001] The invention relates to the field of hydraulic technology, in particular to a hydraulic motor and a pressure regulating device. Background technique [0002] At present, the high water-based hydraulic motor is the core component of the rotary operating machinery in the coal mining face (such as the traveling mechanism of the mobile support, lifting equipment, and the return column winch, etc.), which converts hydraulic energy into mechanical energy. However, for safety and work needs, not only the high water-based hydraulic motor is required to have a power output function, but also a corresponding braking device needs to be installed in the transmission system. Since a separate braking device needs to be set in the transmission system, the transmission system is complicated and the corresponding reliability is reduced; various brakes are installed on the load, which also causes complex mechanism and unchanged operation. The inventors of the present ...
