摘要

研究了弧齿圆柱齿轮在注射润滑过程中的润滑状态。根据啮合原理，建立了圆弧齿圆柱齿轮的数学模型。采用计算流体动力学(CFD)模型，分析了不同注射方式和注射条件下弧齿圆柱齿轮的润滑特性。得到了齿轮啮合区油体积分数的变化规律。对比两种油喷射方式在进网润滑中的应用，当螺距线速度与注射速度之比小于1.5倍时，采用凹面喷射方式获得最佳润滑效果，当螺距线速度与注射速度之比大于1.5倍时，采用凸面喷射方式获得最佳润滑效果。结果表明，在注入润滑油时，齿形对润滑有显著影响。

Lubrication characteristic of tooth surface on arc tooth cylindrical gears

This article studies the lubrication state of the arc tooth cylindrical gears during injection lubrication. The mathematical model of arc tooth cylindrical gears are established based on meshing principle. The lubrication characteristics of arc tooth cylindrical gears under different injection methods and conditions are analysed by using computational fluid dynamics (CFD) model. The variation law of oil volume fraction in the gear-meshing zone is obtained. Comparing the two oil jet methods in into mesh lubrication, when the ratio of the pitch line velocity to the injection velocity is less than 1.5 times, the best lubrication is gained through the concave surface injection method, when the ratio of the pitch line velocity to the injection velocity is more than 1.5 times, the best lubrication is gained through the convex surface injection method. It shows that the tooth shape has significant influence on lubrication when the lubricating oil is injected.

期刊介绍： Lubrication Science is devoted to high-quality research which notably advances fundamental and applied aspects of the science and technology related to lubrication. It publishes research articles, short communications and reviews which demonstrate novelty and cutting edge science in the field, aiming to become a key specialised venue for communicating advances in lubrication research and development. Lubrication is a diverse discipline ranging from lubrication concepts in industrial and automotive engineering, solid-state and gas lubrication, micro & nanolubrication phenomena, to lubrication in biological systems. To investigate these areas the scope of the journal encourages fundamental and application-based studies on: Synthesis, chemistry and the broader development of high-performing and environmentally adapted lubricants and additives. State of the art analytical tools and characterisation of lubricants, lubricated surfaces and interfaces. Solid lubricants, self-lubricating coatings and composites, lubricating nanoparticles. Gas lubrication. Extreme-conditions lubrication. Green-lubrication technology and lubricants. Tribochemistry and tribocorrosion of environment- and lubricant-interface interactions. Modelling of lubrication mechanisms and interface phenomena on different scales: from atomic and molecular to mezzo and structural. Modelling hydrodynamic and thin film lubrication. All lubrication related aspects of nanotribology. Surface-lubricant interface interactions and phenomena: wetting, adhesion and adsorption. Bio-lubrication, bio-lubricants and lubricated biological systems. Other novel and cutting-edge aspects of lubrication in all lubrication regimes.
