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
