< / , -: - ! / , -. For bearings that require transmission accuracy, such as spindle bearings, there are often requirements for preload force. Because these bearings can only achieve nominal accuracy under reasonable preload. For example, the main spindle of a lathe usually has radial thrust roller bearings at the front and back. After assembly, the nuts at both ends need to be pre-tightened to meet the spindle runout requirements.
< / , -: - ! / , -Generally, the preload force is a parameter provided by the bearing factory. However, in the actual assembly process, it is not possible to well measure whether the preload force meets the requirements. Traditionally, assembly workers often install based on experience.
< / , -: - ! / , -In some structures, the method of pre-measurement of the preload deformation can be used. For example, for a radial thrust bearing, the preload force is. We can put the outer ring of the bearing down, put it on the platform, and then apply force on the inner ring. Measure the change in height difference between the inner and outer rings before and after applying force, which can generally be measured using a lever dial indicator. After obtaining the deformation, design a gasket in the preloading structure. The height difference of the gasket is exactly the change before and after preloading. In this way, it is ensured that the preload amount remains unchanged after the nut is tightened. Change the previous assembly method of relying on workers' manual strength to assemble integrated bearings
