摘要/Abstract

摘要： 在滚动轴承动力学理论基础上，建立了双列圆锥滚子轴承非线性动力学微分方程及其摩擦功耗数学模型，采用精细积分法和预估-校正Adams-Bashforth-Moulton多步法相结合的方法进行求解，分析了轴承不同工况参数、结构参数及工艺参数对轴承摩擦功耗的影响。研究结果表明：轴承摩擦功耗随倾覆力矩及转速的增加先缓慢增加然后近似线性增加，转速对轴承摩擦功耗的影响比较明显，在满足使用要求下应尽量选取低转速；侧向载荷比的增加使“压紧侧”轴承摩擦功耗增加，“放松侧”减小，两侧摩擦功耗差值增加；轴承摩擦功耗随大挡边倾角的增加而增加，随滚子球基面半径的增加而减小；滚子波纹度为奇数阶次时，轴承摩擦功耗随波纹度幅值的增加呈先升高后降低的趋势；偶数阶次时，轴承摩擦功耗随波纹度幅值的增加而增加。

Abstract: Based on the dynamic theory of rolling bearings, the nonlinear dynamic equations and friction power consumption mathematical models are established for double-row tapered roller bearings. Fine integral method and predict-correct Adams-Bashforth-Moulton multi-step method are used to solve the equations. The influences of different working conditons, structural parameters and process parameters on bearing friction power consumption are analyzed. The results show that the friction power consumption increases slowly and then linearly increases with the rise in capsized moment and rotating speed. The rotating speed has an obvious effect on friction power consumption, and a lower speed should be selected as much as possible under the premise of meeting the operating requirements. The increase in lateral load ratio makes the friction power consumption of impacted side increase and the friction power consumption of unfixed side decrease. The difference of friction power consumptions of the two sides increases. The bearing friction power consumption increases with the rise in big rim angle, and decreases with the increase in curvature radius of roller end surface. For the odd waviness orders of rollers, the friction power consumption of bearing firstly increases and then decreases with the increase in the waviness amplitude; for the even orders, the friction power consumption of bearing increases with the rise of the waviness amplitude.
