Abstract

Wear is the main failure form of the gear transmission interface, runs through the whole life cycle of gear service, and the distributed error of the tooth surface due to the introduced assembly error will make the actual meshing state of the tooth surface different from the ideal meshing state, thus affecting the tooth surface wear trajectory and state. Therefore, considering the coupling relationship between assembly error and tooth surface contact analysis, the variation laws of the wear amount of the gear transmission interface of the variable hyperbolic circular-arc-tooth-trace cylindrical gear were studied under the consideration of assembly error in this article. Based on the tooth surface contact analysis method and Hertz contact theory, the transient linear load, the combined radius of curvature, the length axis and short axis of the contact ellipse, and the instantaneous sliding velocity were calculated. Through revising the calculation method of adhesive wear of variable hyperbolic circular-arc-tooth-trace cylindrical gears, the correlations between the tooth surface wear amount and gear parameters of variable hyperbolic circular-arc-tooth-trace cylindrical gears under different assembly errors were analyzed. The results show that the maximum wear occurs at the root of the tooth, and the wear at the indexing circle approaches zero, whether it is standard installation or non-standard installation. The vertical axial error and horizontal axial error have little effect on the wear, while the center distance error will aggravate the wear. The proposed method comprehensively considers the influence of assembly error and gear parameters on tooth surface wear, and this method can provide a theoretical reference for the design and analysis of anti-wear, wear reduction, and life extension of variable hyperbolic circular-arc-tooth-trace cylindrical gear tooth surface.

考虑装配误差理论的可变双曲圆弧齿痕圆柱齿轮传动装置磨损特性分析

磨损是齿轮传动界面的主要失效形式，贯穿于齿轮服务的整个生命周期，由于引入装配误差而产生的齿面分布误差会使齿面实际啮合状态与理想啮合状态不同，从而影响齿面磨损轨迹和状态。因此，考虑装配误差与齿面接触分析之间的耦合关系，本文研究了考虑装配误差的变双曲圆弧齿线圆柱齿轮传动界面磨损量的变化规律。基于齿面接触分析方法和Hertz接触理论，计算了瞬态线载荷、接触椭圆的组合曲率半径、接触椭圆的长轴和短轴以及瞬时滑动速度。通过对变双曲圆弧齿线圆柱齿轮黏着磨损计算方法的修正，分析了不同装配误差下变双曲圆弧齿线圆柱齿轮齿面磨损量与齿轮参数的相关性。结果表明:无论是标准安装还是非标准安装，最大磨损发生在齿根处，分度圈处的磨损接近于零;垂直轴向误差和水平轴向误差对磨损影响不大，而中心距误差会加剧磨损。该方法综合考虑了装配误差和齿轮参数对齿面磨损的影响，可为变双曲圆弧齿线圆柱齿轮齿面抗磨、减磨和延长寿命的设计和分析提供理论参考。

期刊介绍： The Journal of Engineering Tribology publishes high-quality, peer-reviewed papers from academia and industry worldwide on the engineering science associated with tribology and its applications. "I am proud to say that I have been part of the tribology research community for almost 20 years. That community has always seemed to me to be highly active, progressive, and closely knit. The conferences are well attended and are characterised by a warmth and friendliness that transcends national boundaries. I see Part J as being an important part of that community, giving us an outlet to publish and promote our scholarly activities. I very much look forward to my term of office as editor of your Journal. I hope you will continue to submit papers, help out with reviewing, and most importantly to read and talk about the work you will find there."
