High-performance multi-blade motor

Abstract

The invention discloses a high-performance multi-blade motor. The high-performance multi-blade motor comprises a shell, a rotor, blades and a sliding shoe; the shell covers the outer part of the rotor, and a circle of circular ring K1 is arranged in the middle of the inner wall of the shell in the direction of the sphere center; an annular groove is formed in the middle of the side wall of the rotor, at least three left sliding grooves which are uniformly distributed in the circumferential direction are formed in the left side surface of the annular groove, and the right side surface of the annular groove is provided with right sliding grooves which are the same as the left sliding grooves and correspond to the left sliding grooves in a one-to-one correspondence mode; the blades are arranged on the left sliding grooves and the right sliding grooves in a sliding mode, the circular ring K1 is clamped between blades of the left sliding grooves and the right sliding grooves, the outer endsof the blades are mounted on the sliding shoe, and the sliding shoe is connected to the side surface of the circular ring K1 in an abutting mode; a containing cavity is formed among the two adjacentblades, the surface of the annular groove, the inner wall of the shell and the side wall of the circular ring K1; and the axis of the rotor and the axis of the shell do not coincide. According to high-pressure oil drives the volume of the containing cavity to enlarge and reduce periodically, so that the rotor are drive to rotate, and therefore the power output is realized.

Description

technical field [0001] The invention relates to a multi-blade motor, in particular to a high-performance multi-blade 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 there a...

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
