Design and Implementation of Oil Supply Mode in Liquid Lubrication Based on Harmonic Principle

Abstract

Abstract:

An oil-supply system in liquid lubrication system was designed based on harmonic principle. The basic structure and oil- supply mechanism were analyzed. The elastomer was one of the main parts. The deformation and particle vibration of the elastomer were as the key factors for oil supplying. The theoretical modes were founded on deformation curve and particle vibration trail of the elastomer. The elastomeric deformation was calculated and analyzed utilizing the finite element software.And the simulation analysis was done for the oil flowing from storage chamber to friction surfaces. The calculation results show that: the radial (bending) deformation of elastomer is emerged under the working load; and the particle vibration is occurred along the radial and circumference directions; the deformation and vibration make the oil flow to friction surfaces from the oil cavity through holes. So the oil supply mode in view of the harmonic principle can be achieved. The effectiveness of this oil supply mode was verified.

Key words: space, liquid lubrication, harmonic principle, oil supply mode, elastomer

摘要：

设计了基于谐波原理的液体润滑供油系统，分析了其基本结构和供油机理。建立了弹性体的变形曲线理论模型和弹性体质点的振动模型；利用有限元软件对弹性体变形进行了计算和分析，对储油腔内润滑油向摩擦表面的供应进行了仿真计算。计算结果表明：工作载荷作用下，弹性体沿径向发生变形，弹性体质点产生振动，质点的振动使储油腔内的润滑油经连通油孔流向摩擦表面，实现了基于谐波原理的润滑油供应，验证了所设计的供油方式的有效性。
