The invention discloses a multifunctional hollow shaft plunger hydraulic motor. The oil cavity, the oil distribution disc, the wedge surface output rolling ring and the cylinder body are sleeved on the peripheral surface of the hollow shaft; the oil distribution disc abuts against the oil cavity and the cylinder body in a sealed mode. A plurality of plunger type cylinders parallel to the axis direction of the hollow shaft are evenly distributed in the cylinder body in the circumferential direction at intervals, a plunger is installed in each plunger type cylinder, one end of each plunger is located in the corresponding plunger type cylinder, and the other end of each plunger extends out of the corresponding plunger type cylinder and abuts against the wedge face output rolling ring. The power density of the hollow shaft motor is effectively increased, the high-power-density hollow shaft output mode is achieved, the thrust output by the plunger can be changed by adjusting the output pressure of the hydraulic pump, and therefore the rotating speed and torque of the hollow shaft are controlled, and the hollow shaft motor is wide in application, small in size, light in weight and low in noise.
Description
technical field [0001] The invention relates to a plunger motor, in particular to a hollow shaft hydraulic motor with multiple plunger hydraulic effects. Background technique [0002] Hollow shaft motors, that is, the output shaft is a hollow metal tube, are widely used, such as water pumps, ventilation equipment, booster equipment, small hydroelectric generators, propellers, etc., which can reduce volume, weight, and noise. At present, the hollow motor mainly adopts the working method of the stator rotor of the traditional motor for driving and output. Compared with the hydraulic system, there are still problems such as low power density, low energy conversion efficiency, large volume, and difficulty in waterproofing. [0003] Traditional hydraulic plunger motors are generally divided into oblique shaft type and swash plate type, which use hydraulic oil to act on the end face of the plunger or piston to make the plunger or piston reciprocate, and then move the plunger throu...
