The selection of bearing bearing profile

The choice of bearing bearing ( 轴承) Summary of choice: using rolling bearing all kinds of machinery, equipment, 设备) Market performance has become increasingly strict, such as for bearing the required conditions ( 挑剑) , performance is also increasingly diversified. Thin wall bearing manufacturer for bearing low friction torque, high rigidity, good rotation accuracy, using the small diameter steel ball. The use of hollow shaft, ensure the lightweight and wiring of the space. Thin wall type bearing has realized the extremely thin cross section of the bearing, also has realized the product miniaturization, lightweight. The diversity of products extends its application scope. Such as cross section thin-walled bearing thin wall bearing ring can be a deep groove ball bearings ( C) At four o 'clock, contact bearing ( X) , angular contact ball bearings ( E) 。 Provide more various design in different series. Series depends on the size of the cross section. The ball and matching series. Deep groove ball bearings can support two-way axial load and radial load. In order to from a large number of structure, size, selection, 选择) The most suitable bearing, need from various angles, angle) Research. When choosing bearing, generally, considered as a shafting bearing arrangement, installation, remove the difficulty level of, bearing, size allowed by the space and marketability of bearing, roughly defines the structure of the bearing. Secondly, a comparative study using bearing a variety of mechanical design life ( 一生) And bearing all sorts of different endurance limit, decided to bearing size. When choosing bearing, tend to be only consider the fatigue life of bearing, by lubrication ( lubrication) Fat ageing grease occurring in the course of life, wear, noise, Db ( dB) ) Also need to fully research. Furthermore, according to different purposes, it is necessary to select precision, clearance, cage structure, grease, etc. , as a special design of the bearing. However, choosing bearing no certain order, rules, consideration should be given priority is to bearing the required conditions, performance, most related matters, especially the actual.
