Jiaxing bearing group co. , LTD. : the axial preload method

【 Jiaxing bearing group co. , LTD. ) Jiaxing bearing group sales co. , LTD. , is the spot sales center of jiaxing bearing factory, specializing in HRB bearings, application in production design and related machinery has a wealth of technical experience, today we are together and our experts to study the method of axial preload. Axial preload method: axial preload method in general can be divided into two locating preloaded and constant pressure preload. In positioning preloaded, can be adjusted through sleeve or the size of the gasket, obtain proper preload; Can also be a tuning by measurement or control starting friction torque suitable pre-tightening; Can also be used directly in advance amount adjusted the preload double bearings in pairs to achieve the purpose of the pre-tightening, generally do not need to users adjust any right now, all in all, by the bearing axial preload, when using its relative position will not change. Constant pressure preload is to use such as spiral spring, disc springs for bearing pre-tightening appropriate methods. Preloaded spring rigidity is much lower than the stiffness of bearing, so the relative positions of constant pressure preload bearing in use will have change, but the preloaded were roughly the same amount. Positioning of preloaded with constant pressure preload is as follows: ( 1) Located in equals the quantity of preloaded, preloaded bigger effect on the bearing stiffness increases, and positioning when the preloaded stiffness change influence on bearing load are much smaller. ( 2) Positioning preloaded in use, due to the difference in temperature between shaft and bearing axial length difference, the difference in temperature between inside and outside the circle caused by radial expansion volume and the displacement caused by load, the influence of prestressing quantity will make changes; In use, and the constant pressure preload preload changes can be neglected.
