Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] Such as figure 1As shown, a high-torque vane hydraulic motor includes a motor housing 1. The inner wall of the motor housing 1 forms a motor inner cavity 36 with a protruding petal-shaped structure in cross section. The oil inlet 2 and the oil outlet 3, the motor inner cavity 36 has a motor shaft 4, the motor shaft 4 is generally arranged along the central axis of the motor inner cavity 36 and the two ends of the motor housing 1 are rotatably worn, the motor shaft 4. The part located in the inner cavity 36 of the motor is fixedly provided with a rotor 5. The rotor 5 is cylindrical and ha...

Abstract

The invention discloses a large-torque vane type hydraulic motor which comprises a motor shell, a sealed motor inner cavity is formed by the motor shell and a side cover together, the section of the motor inner cavity comprises a circular main body and gradually-changed outwards-protruding parts which are evenly distributed along the circumference of the circular main body and communicated with the circular main body, and the motor inner cavity is further provided with an oil inlet and an oil outlet. A motor shaft is arranged in the motor inner cavity and arranged on the motor shell in a penetrating mode, a rotor is fixedly arranged on the portion, located in the motor inner cavity, of the motor shaft, evenly-distributed blades are arranged on the outer surface of the rotor, and the blades make closed contact with the inner wall of the motor shell to divide the portion, between the rotor and the inner wall of the motor, of the motor inner cavity into independent cavities. The blades are arranged in pairs through the linkage mechanism, each blade is connected to the rotor in a telescopic mode, and when the rotor rotates, one blade arranged in pairs moves in the radial direction and can drive the other blade to move in the radial direction. The internal friction force is small, and the torque and the rotating speed of the motor can be improved under the condition that the use cost is not increased.

Description

technical field [0001] The invention relates to the field of hydraulic motors, in particular to a high-torque vane hydraulic motor. Background technique [0002] The speed of the hydraulic motor is positively related to the flow of hydraulic oil, and the torque is related to the pressure of the hydraulic oil. When the pressure and flow of the hydraulic oil are constant, the torque and speed are usually also determined. Different application scenarios have different requirements for hydraulic motors. Unchanged torque and speed will inevitably produce more waste. [0003] The vane hydraulic motor is small in size, small in moment of inertia, and sensitive in action. It is generally used in occasions with high speed, small torque and sensitive action requirements. Since the blades are always in contact with the inner wall of the stator when rotating, the blades are usually designed to be very thin in order to reduce friction, and in order to obtain a higher speed, that is, to ...
