introduction: bearing[bearing:bearing(“Bearing”,Japanese person“Axial receptor”)It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said,When other parts move relative to each other on the shaft,A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The speed of the bearing is mainly limited by the temperature rise caused by friction heat inside the bearing,When the speed exceeds a certain limit,Bearings will not continue to rotate due to burns, etc。 The limit speed of the bearing refers to the limit value that does not produce friction heat that causes burns and can be continuously rotated。 therefore,shaft
