Abstract

The invention discloses a high-performance multiple-blade hydraulic motor which comprises a casing, a rotor, vanes, seal strips, oil distribution cones and cushion blocks, wherein the rotor is arranged in the center; the casing is arranged at the external part; the oil distribution cones are arranged in the hollow circular-truncated-cone surfaces at the two ends of the rotor; the vanes are arranged in hollow circular rings at the opposite angles of the casing and also arranged in the grooves of the rotor, and form angles together with the rotor; one plane of each vane is fitted with the circular-truncated-cone side surface of the corresponding oil distribution cone; the seal strips are arranged between the rotor and the vanes, one side of the plane of each seal strip is fitted with the rotor, and one side of the circular-truncated-cone-surface of each seal strip is fitted with the circular-truncated-cone surface E1 of the corresponding vane; the cushion blocks are arranged in the hollow circular rings at the opposite angles of the casing, and gaps formed by the casing, the vanes, the rotor and the seal strips are just filled up with the cushion blocks. All sealed parts adopt face seal; the vane type hydraulic motor is small in size, large in torque, high in efficiency and specific power, compact in structure, easier to process, lower in cost and long in service life.

Description

technical field [0001] The invention relates to a hydraulic 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 ...
