Problems solved by technology

However, there is no braking part in any of the existing models. If this inner curve radial piston hydraulic motor is applied to machinery, an additional braking structure is required, and the brake is used separately from the inner curve radial piston hydraulic motor. and installation, high cost, inconvenient installation and operation

Embodiment Construction

[0019] The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.

[0020] like figure 1 shown, is the first embodiment of the present invention.

[0021] A shell-rotating inner-curve radial piston hydraulic motor, comprising a casing composed of a front cover 1, a stator 2 and a rear cover 3, the front cover 1 and the rear cover 3 are fixed on the front and rear ends of the stator 2, and the front cover 1. The stator 2 and the rear cover 3 are fixed together by a plurality of screws 18.

[0022] The casing is installed with an oil passage shaft 4, a rotor 5 and an oil distribution plate 6, the rotor 5 is fixed on the oil passage shaft 4, the inner hole of the rotor 5 is connected to the oil passage shaft 4 through splines, and the front end of the oil passage shaft 4 is set. There is a lock nut 17 for axially limiting the rotor 5 . A plurality of radially arranged plunger holes 51 are arranged on the peri...

Abstract

The invention relates to a shell turn type inner-curve radial plunger hydraulic motor, which comprises a machine casing composed of a front cover, a stator and a rear cover. The machine casing is provided with an oil through shaft, a rotor and an oil distribution disc. The shell turn type inner-curve radial plunger hydraulic motor is characterized in that the oil distribution disc is sleeved on the oil through shaft and fixed with an inner scapula of the rear cover, a fixed brake seat is fixed on the periphery of the oil through shaft, the machine casing can rotate around the axis relative to the oil through shaft, and a plurality of dynamic friction sheets and a plurality of static friction sheets which are arranged at mutual intervals and in an overlaying mode are sleeved on the periphery of the fixed brake seat. A plunger is further arranged in the rear cover and sleeved on the fixed brake seat and can glide in the axial direction, a spring enabling the plunger to keep the mutual tight compression between the dynamic friction sheets and the static friction sheets is further arranged in the rear cover, a sealed oil cavity is formed between the plunger and fixed brake seat, and the fixed brake seat is provided with an oil hole communicated with the oil. The shell turn type inner-curve radial plunger hydraulic motor is provided with a brake structure organically combined with the hydraulic motor, thereby being compact and reasonable in structure.

Description

technical field [0001] The invention relates to a shell-turning inner-curve radial piston hydraulic motor. Background technique [0002] The inner curve radial piston hydraulic motor is mostly shaft-rotating, that is, the cylinder body is relatively fixed, and the transmission shaft rotates relative to the cylinder body to output torque and speed. Its structure includes a cylinder body formed by a cover plate, a rear cover, a stator and a front cover. , the front cover and the rear cover are fixed on the front and rear ends of the stator, the transmission shaft and the distribution shaft are installed in the cavity of the cylinder block, the front part of the transmission shaft is supported on the front cover through two rolling bearings arranged at the front and rear, and the distribution shaft is installed in the In the rear cover, the front end of the transmission shaft extends out of the front cover to output torque and rotational speed. The transmission shaft is also eq...
