Problems solved by technology

However, due to the existence of gaps in the above two distribution structures, and with the wear and tear of the moving pair, the gap will gradually increase, so the increase of its working pressure is limited.
The check valve distribution has good sealing performance and can be used in radial piston hydraulic pumps to achieve high pressure and ultra-high pressure. However, since ordinary check valves only allow one-way flow, they cannot be used for radial piston hydraulic motors. Flow distribution, this type of radial piston hydraulic device can only work in the pump state

Abstract

The invention discloses a hydraulic control one-way valve flow distribution radial plunger hydraulic device controlled by a rotating shaft. The hydraulic control one-way valve flow distribution radial plunger hydraulic device comprises a shell, a plurality of plunger assemblies, a main shaft, the rotating shaft, first hydraulic control one-way valves and second hydraulic control one-way valves, wherein the number of the first hydraulic control one-way valves and the number of the second hydraulic control one-way valves are the same as that of the plunger assemblies, and the first hydraulic control one-way valves and the second hydraulic control one-way valves are in one-to-one correspondence with the plunger assemblies. The radial plunger hydraulic device is compact in structure, simple in transmission, capable of stably working under the high-pressure working condition and small in leakage amount. Meanwhile, external hydraulic source control is not needed, and oil connection is easy and convenient. The oil distribution pressure of the rotating shaft can be adjusted by a liquid resistor. Supporting is reliable, and work is stable. The main shaft and the rotating shaft are reliably supported and are not easy to deform, so that the shafts rotate more stably. A flow distribution pair is less in friction, working is stable, and the service life is long.

Description

technical field [0001] The invention relates to a hydraulic control one-way valve flow distribution radial plunger hydraulic device controlled by a rotating shaft. Background technique [0002] Radial plunger hydraulic devices, such as hydraulic motors and hydraulic pumps, have the characteristics of low speed and high torque, and are widely used in injection molding machines, construction machinery and other fields. The radial piston hydraulic pump is a type of hydraulic power device used to provide oil with a certain pressure for the hydraulic system. Radial piston hydraulic motor is a common hydraulic actuator used to drive the working mechanism to rotate at a certain speed. The output power of a hydraulic pump or hydraulic motor depends on its working pressure and flow rate. The higher the working pressure, the greater its output power, and it can drive a larger load. [0003] The flow distribution methods adopted by the existing radial plunger hydraulic devices mainly...
