Ball and Roller Bearings

Rolling bearings have extremely important and wide ranging uses in modern technology. From high speed transport to bridges, from miniature instruments to machinery moving heavy loads, rolling bearings play a vital part. This book presents information which will be essential to designers and to other people concerned with rolling bearings. Classification of bearings is discussed in terms of shape, use and size. Materials having suitable properties for the manufacture of rolling bearings are described. Problems associated with the working performance of rolling bearings, such as lubrication, stress, etc., are looked into. The classical experimental work of Hertz, mathematically relating vital factors involved when loads are applied to spherical objects, is described. This leads on to Stribeck's and Goodman's work on the running characteristics of rolling bearings; and that of Palmgren on fatigue and hence safety. The published data are vast, as is reflected by the bibliography, but this text concentrates on those factors which are of direct value to the designer and technical businessman. Worked examples are given to relate data to practical design problems and, where possible, results are compared with standard lists. Contents: 1. Rolling Bearings 2. Bearing Types 3.
