摘要

达芬奇(1452-1519 年)的笔记本是文艺复兴时期技术信息的独特来源。这些笔记本包含大量摩擦学主题的参考文献,包括基于轴上滚动元件(圆盘、圆锥和扇形轴承)或自由滚动球、圆锥或滚子的轴承设计。本文基于莱昂纳多的所有手稿,首次对这些材料及其背景进行了全面研究。虽然他的一些轴承设计(如使用扇形轴承支撑钟)显然是基于已有的技术,但他对这些设计背后的原理有着深刻的理解,并在进一步开发这些设计时表现出了非凡的创造力。然而,在某些情况下,这些研发存在固有缺陷,或由于其他原因而完全不切实际。虽然滚子轴承的发明早于莱昂纳多的作品,但在轴向轴承中使用自由滚动球的概念似乎源自莱昂纳多。

Leonardo da Vinci's studies of rolling-element, disc and sector bearings
The notebooks of Leonardo da Vinci (1452–1519) represent a unique source of information on Renaissance technology. They contain numerous references to tribological topics, including designs for bearings based either on rolling elements on axles (disc, cone, and sector bearings) or on freely rolling balls, cones or rollers. This paper provides the first comprehensive study of this material and its context, based on all of Leonardo's surviving manuscripts. While some of his bearing designs (such as the use of sector bearings to support bells) were clearly based on pre-existing technology, he showed a deep understanding of the principles behind them and remarkable ingenuity in developing them further. In some cases, however, these developments suffered from intrinsic defects or were completely impractical for other reasons. Although roller bearings pre-dated the work of Leonardo, the concept of using freely rolling balls in axial bearings appears to have originated with him.

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." Professor Rob Dwyer-Joyce, Sheffield University, UK This journal is a member of the Committee on Publication Ethics (COPE).
