一、概述无铰型斜轴式轴向柱塞泵(简称斜轴泵),在工程机械中显示出多方面的优越性,因而得到广泛的应用。如煤炭工业部门,使用国外引进元件,在工况极端恶劣的条件下,效果显著。而煤炭是我国第一能源,仅从这一工业部门看,这种液压动力元件就有着广阔的发展前途。近年来,国外斜轴泵在技术性能、结构形式、产品类型等方面,都有令人注目的提高与 I. Overview Non-hinged inclined axis axial piston pump (referred to as oblique axis pump), in construction machinery showed many advantages, which has been widely used. Such as the coal industry sector, the use of imported components, under extremely harsh conditions conditions, the effect is remarkable. The coal is China’s first energy, only from the industrial sector, this hydraulic power components have a broad development prospects. In recent years, foreign oblique axis pump in terms of technical performance, structure, product type, etc., have remarkable improvement and
