Floating swash plate follower ball hinge conical plunger variable pump/motor rotation assembly

Abstract

The present invention disclosed a floating diagonal disk hinge hinge hinge hinge pump / motor rotation component, including floating diagonal and cone plunged rotation components.The front -end ball head and the rotating ball nest of the cone plunger are hinged. The back end only has the spherical area area and the pillar wall of the cylinder body.The principle of force solves the problem of friction and wear caused by the huge side force and torque caused by the traditional fixed oblique disk -type axial plunger pump.The inner plate of the floating diagonal disk is fixed with the rotating plate. The rotating disc is driven by the hinge of the cone -shaped plunger ball. Due to the support of the bottom roller and the side roller, the rotation disc and the inner disc renewal movement, so that the rotation and inner discs will turn around, thereby the rotation movement, thereby the rotation movement.The sliding movement of the original sliding boots and the sliding boots and the sliding boots and the slash plate converted into the rolling movement between the side roller and the bottom roller, which achieved the purpose of reducing the loss of the sub -friction power loss of heavy -duty skate boots.

Description

technical field [0001] The invention relates to the technical field of fluid transmission and control, and is applicable to a swash plate axial piston pump / motor, in particular to a floating swash plate follower ball hinge joint conical plunger variable displacement pump / motor rotary assembly. Background technique [0002] Due to its structural characteristics, the swash plate axial piston pump / motor is resistant to high pressure and can realize various variable functions, especially the displacement of the pump / motor can be easily controlled and adjusted, so that the output power of the pump / motor and the load Therefore, it has become the trump card component in hydraulic transmission technology. It has been widely used as the most important core power / executive component in hydraulic transmission system. It is a direct reflection of the development level and scientific and technological strength of a country's hydraulic component manufacturing. In the swash plate axial pis...

Problems solved by technology

The long-term technical means to improve the anti-friction and anti-wear performance of the swash plate axial piston pump / motor plunger pair and the sliding shoe pair is based on the optimization design of the lubricating support structure, the surface modification of the friction interface and the surface microscopic modification technology, and has achieved Some important technological advances have not completely solved the problem. The friction and wear of the plunger pair and the sliding shoe pair and the failure of lubrication are still the most important technical problems restricting the performance of the swash plate axial piston pump / motor. Because the plunger The frictional power loss between the pair and the sliding shoe pair is large, resulting in low efficiency of the swash plate axial piston pump / motor under small displacement conditions, which adversely affects the overall transmission efficiency of the pump control transmission system
