Multiple-blade hydraulic motor with high performance

Abstract

The invention discloses a multiple-blade hydraulic motor with high performance. The multiple-blade hydraulic motor with high performance comprises a shell body, a rotor, blades and sliding shoes; theshell body covers the outer part of the rotor and is in a hemisphere shape, a circular ring K1 extends inwards from the end face of the shell body, and the circular ring K1 penetrates through the center of a sphere of the shell body; at least three sliding grooves are formed in the rotor and are uniformly distributed in the circumferential direction, the blades are slidably arranged in the slidinggrooves, the outer ends of the blades are installed on the sliding shoes, and the sliding shoes abut against the side surface of the circular ring K1; a containing cavity is formed among the adjacenttwo blades, the surface of the rotor, the inner wall of the shell body and the side wall of the circular ring K1; the axis of the rotor and the axis of the shell body are not coincident; and the volume of a cavity chamber is driven by high pressure oil to be increased and decreased periodically, and thus the rotor is driven to rotate, and the output of power is achieved.

Description

technical field [0001] The invention relates to a multi-vane motor, in particular to a high-performance multi-vane hydraulic motor. Background technique [0002] The structure of the existing vane hydraulic motor is that the rotor is eccentrically placed in the oil cylinder body, and the blades are placed in the rotor radially or at a certain angle with the rotor radius. Form a sealed cavity. This form of vane hydraulic motor is sealed by a contact line between the vane and the cylinder body, so the sealing performance is poor, the output torque is low, and there is a lot of friction between the vane, the rotor and the cylinder during rotation, resulting in the blade The overall wear of the hydraulic motor is fast, the life is short, and the efficiency is low. In addition, in order to ensure that the blades can safely enter and exit the rotor during rotation, the rotor must have a considerable diameter, which is bound to be large in size and low in specific power. Although...

This form of vane hydraulic motor is sealed by a contact line between the vane and the cylinder body, so the sealing performance is poor, the output torque is low, and there is a lot of friction between the vane, the rotor and the cylinder during rotation, resulting in the blade The overall wear of the hydraulic motor is fast, the life is short, and the efficiency is low

In addition, in order to ensure that the blades can safely enter and exit the rotor during rotation, the rotor must have a considerable diameter, which is bound to be large in size and low in specific power. Although there are double-blade hydraulic motors, since there are only two blades, the output torque fluctuates greatly , the output torque is also undersized
