A high-performance high-torque multi-blade motor

Abstract

The invention discloses a high-performance and large-torque multi-blade motor. The high-performance and large-torque multi-blade motor comprises a shell body, a rotor and blades, a round of ring K1 extends in the center of the inner wall of the shell body to the direction of center of a ball, and at least three first positioning grooves are evenly formed in the inner wall of the shell body in thecircumferential direction. A second positioning groove is formed in the ring K1, and the blades are arranged on the first positioning grooves and the second positioning groove at the same time. The second positioning groove divides the ring K1 into a plurality of partition plates, a ring groove is formed in the center of the rotor side wall, left sliding grooves corresponding to the first positioning grooves one by one are formed in the left side surface of the ring groove, right sliding grooves corresponding to the first positioning grooves one by one are formed in the right side surface of the ring groove, the two ends of the blades are separately placed on the left sliding grooves and the right sliding grooves in an accommodating mode. An accommodating cavity is formed between the adjacent two blades, the surface of the ring groove and the inner wall of the shell body, each partition plate is arranged in each accommodating cavity, and the partition plates divide the accommodating cavities into left accommodating cavities and right accommodating cavities. The volume of the accommodating cavities is driven by high pressure oil to increase and decrease periodically, so that the rotor is driven to rotate, and the output of power is realized.

Description

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

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
