High-performance vane hydraulic motor

Abstract

The invention discloses a high-performance vane hydraulic motor. The high-performance vane hydraulic motor comprises a housing, rotors and vanes, the rotors are covered with the housing, the housing is in a hemispheric shape, a lap of circular ring K1 is arranged on the end face of the housing in an inward extending mode, the vanes are mounted on locating grooves, sliding grooves corresponding tothe locating grooves in an one-to-one mode are formed in the rotors, the vanes on the locating grooves are further arranged on the sliding grooves in a sliding mode and are sealed through sealing elements, the outer ends of the vanes are mounted on sliding shoes, the sliding shoes abut against the side face of the circular ring K1, a containing cavity is formed among every two adjacent vanes, thesurface of a circular groove, the inner wall of the housing and the side wall of the circular ring K1, oil ports are formed in the rotors and are the same as the containing cavities in number, one oilport communicates with the corresponding containing cavity, the two ends of the rotors are connected with oil distribution blocks, a convex circular ring J1 is arranged on the outer wall of the housing, the convex circular ring J1 is arranged in a guide groove of a guide block, and the axis of the rotors and the axis of the housing do not coincide. The volume of a high-pressure oil driving chamber is increased or decreased periodically, thus the rotors are driven to rotate, and power output is realized.

Description

Technical field [0001] The invention relates to a multi-blade motor, in particular to a high-performance blade hydraulic motor. Background technique [0002] The existing vane-type hydraulic motor structure is that a rotor is eccentrically placed in the cylinder body, and the vanes are placed in the rotor radially or at a certain angle to the rotor radius. During operation, the vanes are thrown out under the action of spring or oil pressure, and the cylinder body Form a sealed cavity. This type of vane type hydraulic motor is sealed by a contact line between the vane and the cylinder block, so the sealing performance is poor, the output torque is low, and the blades and the rotor and the cylinder block generate a lot of friction during rotation, resulting in the vane Type hydraulic motor has fast overall wear, short life and low efficiency. In addition, in order to ensure that the blades can safely enter and exit the rotor during rotation, the rotor must have a considerable dia...

AI Technical Summary

Problems solved by technology

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
