Abstract

The invention provides an innercurve multiple-action radial plunger type hydraulic motor, wherein, the plunger holes of a rotator are connected with rollers, a sliding bearing, a plunger and elastic retaining rings; the elastic retaining rings are evenly distributed with claw elbows in a circumference direction; two ends of the outer surface of the rotator are provided with a groove respectively; two end surfaces of the rotator are provided with notches which are communicated with the plunger holes and have the same number as the plunger holes; the elastic retaining rings are clamped in the two grooves on the outer surface of the rotator; the claw elbows on the elastic retaining rings are in clearance fit with the two end surfaces of the roller in each plunger hole; and the rollers are clamped in the middle of two claw elbows. Each elastic retaining ring is of an integral structure, thus the ring does not need to be assembled in each plunger hole independently; and only two elastic retaining rings are clamped in the grooves on the rotator so as to limit the rollers in all the plunger holes to axially move, thereby leading even stress on the rollers, enabling a hydraulic energy conversion part to work stably, improving the mechanical efficiency and the reliability of the hydraulic motor, and prolonging the service life of the hydraulic motor.

Description

technical field [0001] The invention relates to a hydraulic motor, in particular to an inner curve multi-action radial plunger hydraulic motor. Background technique [0002] In order to limit the movement of the roller along its own axis in the inner curve multi-action radial plunger hydraulic motor, the traditional method needs to install stoppers at both ends of the roller. The method of installing the stopper is on each plunger hole Process the groove matching the stopper, and then fix it on the rotor with screws. Using this method, although the movement of the rollers along the axis can be effectively restricted, the groove of the fixed stopper needs to be processed on the plunger hole, which affects the machining accuracy of the plunger hole, and the processing accuracy of the groove and the stopper is also very high. , Low production efficiency. In addition, due to the high-speed operation of the hydraulic motor, in order to prevent loosening, it needs to be bonded w...
