Study on minimum oil film thickness distribution in sliding bearing of an internal combustion engine 內(nèi)燃機(jī)滑動軸承最小油膜厚度分布狀態(tài)的研究
The experimental equipment based on theoretical analysis and simulation was set up hi order to measure the oil film thickness of the ball friction coupling and the slipper coupling based on hydrostatic support 在理論分析和仿真結(jié)果的基礎(chǔ)上,設(shè)計出測量球鉸副和滑靴副油膜厚度的實驗臺。
On the other hand , the quasi - dynamic method has advantages in calculational efficiency . ( 2 ) the minimum oil film thickness and oil film stiffness characteristics of ball bearings are studied by the elastohydrodynamic lubrication theory ( 2 )基于彈流潤滑理論,研究了滾動軸承的最小油膜厚度和油膜剛度特性,分析了不同載荷參數(shù)對它們的影響規(guī)律。
3 ) based on the analysis result of equal contact stress curve and the theory of elasto - hydrodynamic lubrication , the expression of the oil film thickness between roller ( or ball ) and orbit are calculated . the simulation result proved that the thickness of oil film is enough for bearing and lubricating ( 3 )基于等接觸應(yīng)力曲線的求解結(jié)果和彈性流體動力潤滑理論,求得滾動體和軌道曲線間的油膜厚度表達(dá)式,并通過仿真分析論證了馬達(dá)正常工作時這種油膜能滿足承載能力和潤滑的需要。
