Description

technical field [0001] The invention relates to the technical field of hydraulic machinery, in particular to a hydraulic machinery based on the principle of cam transmission. Background technique [0002] Hydraulic machinery is equipment and tools that can work through fluids. In this type of equipment, hydraulic oil is transmitted to the actuator in the equipment at high pressure through a hydraulic pump, and the hydraulic pump is driven by an engine or an electric motor. Various hydraulic control valves control the hydraulic oil to obtain the required pressure or flow, and the hydraulic components are connected through hydraulic pipes. The liquid is pressed from the oil inlet side to the oil discharge side of the pump. When the vane pump rotor rotates, under the action of centrifugal force and pressure oil, the tip of the vane is close to the inner surface of the stator. In this way, the working volume formed by the two blades and the inner surface of the rotor and the st...

AI Technical Summary

Problems solved by technology

[0003] The existing hydraulic vane motor adopts a spring structure to make the vane close to the stator to start work. It has inherent shortcomings brought about by this structure. There is sliding friction between the rotor vane and the stator, and the friction loss on the surface of the stator is large, which affects product performance and service life. Moreover, when the spring is used for a long time, it is easy to cause metal fatigue and fail. The failure of the spring will cause poor reliability and reduce the oil delivery capacity of the hydraulic vane motor. At the same time, due to the limited space in the stator, in order to ensure the performance of the hydraulic vane motor , the thickness of the blade is very limited, and the blade is often deformed under the action of high-pressure fluid, which leads to a decrease in product efficiency and increases product maintenance costs

[0004] In order to solve the above problems, the inventor provides a hydraulic machine based on the principle of cam transmission, which is equipped with stator rotating oil suction and oil discharge, can accept high working intensity, will not deform, works reliably, and avoids work efficiency caused by blade deformation Reduce the rolling friction between the roller and the stator, change the sliding friction to rolling friction, reduce friction, reduce friction loss, increase the service life of the product, remove the spring to control the sliding rotation of the blade and the stator, the structure is simpler and more stable, The advantages of increasing the reliability of work and avoiding hydraulic oil delivery problems due to spring failure
