浮杯原理及其在液压系统中的应用研究

Floating-cup Principle and Its Application Research in the Hydraulic System

浮杯原理是继斜盘式和斜轴式之后一种新的轴向柱塞概念,将现有泵原理的优点结合在了一起。最显著特征是结构镜像对称设计以及柱塞固接在转子上,且每个活塞对应一个独立的杯状缸筒,它可以沿旋转斜盘面自由浮动。浮杯泵具有结构紧凑、质量小、泄漏小、受力平衡、力矩损失小、波动小、噪声小、效率高、生产成本低等优点。浮杯原理将被广泛应用在液压定量和变量泵、液压变压器和液压马达等方面。该文针对浮杯泵的研发现状、结构特点、优点等方面进行了详细的分析和梳理,对浮杯原理在定量/变量泵、液压变压器、液压马达的应用发展状况进行了介绍。该文将为浮杯泵的进一步研发及浮杯原理更广泛应用提供参考。

The floating cup principle is a new axial piston concept,combining the advantages from the slipper-type and bent-axis principle.Most striking is the mirrored design of the new concept.Besides,the pistons are rigidly connected to the rotor and each piston has its own separate cuplike cylinder.These ‘cups＇ are floating on and supported by a barrel plate.A floating cup pump has such advantages as a compact structure,low-weight,small leakage,force balance,small torque loss and fluctuation,low noise,high efficiency and low production cost.The floating cup principle is widely applied in hydraulic constant and variable displacement pump,hydraulic motor and hydraulic transformer,etc.This paper focuses on the detailed analysis of floating cup pump,including the present research and development,structure characteristics and advantages.It also describes the application of floating cup principle in constant and variable pump,hydraulic motor,hydraulic transformer.This paper will provide the reference for the further development of floating cup pump and more application of the floating cup principle.
