Rolling-element bearings in China: From ancient times to the 20th century

Lie SUN,Ang LI

Frontiers of Mechanical Engineering 2016, Volume 11, Issue 1, Pages 33-43 doi: 10.1007/s11465-016-0373-2

Abstract:

The development of rolling-element bearings in China has spanned a long period.bearings in China by dividing it into four stages according to the various characteristics of the bearingsThe first stage represents the origin of rolling bearings in China, which remains controversial becauseAnother type of spherical thrust bearings with rolling elements, which is a key component of a traditionalbearings as replacement for traditional sliding bearings.

Outline of Strip Rolling Technological Control Theory

Zhang Jinzhi

Strategic Study of CAE 2001, Volume 3, Issue 4, Pages 46-55

Abstract:

Classical rolling theory, which is based on the law of the lowest resistance,the condition of constantvolume and the condition of equal flow per second,has formed a fairly integrated rolling applied technologyThis system reflects only the static law of rolling process,so it is necessary to control dynamic rollingtheory, classical rolling theory based on mechanics took the lead before the establishment of springA new theory system, which is based on fundamental rolling technology control theory, is set up.
