FUNDAMENTALS of Design Topic 10 Bearings

Аннотация

The evolution of technology is heavily dependant upon matching observations with needs. Did the idea for a rolling element bearing come from someone noticing a rock rolling down a hill, or from someone falling after stepping on a round log that rolled out from beneath them? Bearings are machine elements that allow components to move with respect to each other. Bearings are used to support large skyscrapers to allow them to move during earthquakes, and bearings enable the finest of watches to tick away happily. Without bearings, everything would grind to a halt, including people, whose joints are comprised of sliding contact bearings!
