摘要

齿轮齿间的摩擦是造成齿轮传动能量损失的重要原因。负载、速度和摩擦系数 (µ) 等因素在决定齿轮摩擦损耗程度方面起着至关重要的作用。摩擦系数(µ)是一个复杂的函数,受各种摩擦学参数的影响,包括滚动和滑动速度、齿接触区的法向载荷、油温和接触表面粗糙度。为了分析设计和运行参数对摩擦系数的影响,我们采用了一种综合统计参数方法,将数值方法和统计方法相结合。研究采用了实验设计方法,从数值上检验了各种摩擦学因素对摩擦系数的影响。这种方法有助于确定对变量 µ 有重大影响的主要效应和关键因素。随后,将计算模型得出的结果与包括实验和理论方法在内的已有研究结果进行了比较。所提出的方法是了解主要摩擦学因素与摩擦系数之间关系和相关性的有力工具。通过采用这种方法,可以确定优化的摩擦学参数。这些信息对于改进齿轮系统的设计和运行非常有价值,可以减少摩擦造成的能量损失,提高整体效率。

Utilizing design of experiments techniques to determine the optimal coefficient of friction in spur gears
The friction occurring between the teeth of gears is a significant contributor to energy loss in gear drives. Factors like the load, speed, and coefficient of friction (µ) play a crucial role in determining the extent of frictional losses in gears. The coefficient of friction (µ) is a complex function influenced by various tribological parameters, including rolling, and sliding velocities, normal load at the tooth contact zone, oil temperature, and contact surface roughness. To analyze the impact of design and operating parameters on the coefficient of friction, a comprehensive statistical parametric approach was employed, combining numerical and statistical methods. The study employed a design of experiments methodology to numerically examine the impact of various tribological factors on the coefficient of friction. This methodology facilitated the identification of primary effects and crucial factors that have a significant impact on the variable µ. The findings derived from the computational models were subsequently compared with the discoveries of pre-existing investigations that includes both experimental and theoretical approaches. The proposed method represents a powerful tool for understanding the relationship and correlation between major tribological factors and the coefficient of friction. By employing this approach, it becomes possible to identify optimized tribological parameters. This information is valuable in improving the design and operation of gear systems, with the aim of reducing energy loss due to friction and enhancing overall efficiency.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
