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.

Embodiment Construction

[0027] figure 1 a and figure 1 b shows the shape of the blade 3 and the sealing strip 4 of the present invention. The blade 3 is approximately semicircular, and has two identical pieces, wherein A1 and B1 are parallel planes, and the width of the blade 3 is the same as Figure 4 b The width of the hollow ring of shell 1 is equal, C1 is the cylinder whose center is O1 and the radius of E4 is the same as that of the cylinder of shell 1, D1 is the spherical surface whose center is O1 and the radius of C2 of the ball table of rotor 2 is the same, E1 is the cylinder Surface, the E1 cylindrical surface takes the symmetry axis passing through the center of the sphere O1 as the central axis, and takes O1K1 as the radius.

[0028] There are four identical sealing strips 4, one of which has a cylindrical surface with a radius equal to that of the blade 3 cylindrical surface E1 on the upper side, and a plane on the lower side, and the vertical distance between the spherical center O1 ...

Abstract

The invention discloses a spherical hydraulic motor, which comprises a casing, a rotor, two blades, four sealing strips, two oil distribution cones and two cushion blocks. all the sealing places of the motor are surface sealing, and the motor has the advantages of large displacement, high pressure and efficiency, large specific power, compact structure, easy machining, lower cost and long service life.

Description

technical field [0001] The invention relates to a hydraulic motor, in particular to an overall scheme design of a novel high-performance vane type hydraulic motor. Background technique [0002] The structure of the existing vane hydraulic motor is that the rotor is eccentrically placed in the cylinder body, and the radial direction of the vane is placed in the rotor at a certain angle with the radius of the rotor. 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 inevitably leads to large v...
