    摘要:

    以低速大扭矩水壓馬達(dá)支承軸轉(zhuǎn)子副為研究對(duì)象，在確定的水壓馬達(dá)初始參數(shù)下,，基于力平衡方程及流量方程,，建立了功率損失,、靜態(tài)和動(dòng)態(tài)的數(shù)學(xué)模型,；以總功率損失,、承載能力,、靜剛度,、轉(zhuǎn)子徑向速度和位移等作為支承軸轉(zhuǎn)子副的性能指標(biāo),，分析了水膜厚度對(duì)支承軸轉(zhuǎn)子副性能的影響。研究表明：增大水膜厚度,，支承軸的功率損失增加,，轉(zhuǎn)子的靜剛度降低，水壓馬達(dá)的容積效率降低,，轉(zhuǎn)子的徑向速度和位移增加,，但承載能力不受其影響。因此,，減小水膜厚度,，可提高水壓馬達(dá)的容積效率和支承軸轉(zhuǎn)子副的靜、動(dòng)態(tài)性能,。

    Abstract:

    The aim of this paper was to find an appropriate water film thickness to improve the volumetric efficiency of water hydraulic motor and the static and dynamic characteristics of the supporting shaft rotor pair. Based on the equilibrium equation and the flow equation, the mathematical models of the power loss, the static characteristics and the dynamic characteristics were established. The total power loss, the bearing capacity, the static stiffness, the radial velocity and the displacement of rotor could be the performance indexes of the supporting shaft rotor pair. Different size of the water film thickness had different performance indexes. So the influence of the water film thickness on the supporting shaft rotor pair was analyzed in detail. The research showed that when the water film thickness was increased, the power loss, the radial velocity and the displacement of rotor were increased, the static stiffness and the volumetric efficiency were reduced, but the bearing capacity kept constant. 
