Does the type of bearing have an impact on shaft play?
Thread Content
For example, when angular contact bearings are arranged in pairs, it seems that there is no shaft play
It is impossible to achieve complete absence of axial play; bearings that provide axial positioning, whether they are sliding thrust bearings or deep groove ball bearings, as well as angular contact ball bearings used in pairs and tapered roller bearings, all must have some axial clearance, otherwise the equipment cannot operate.
Select the bearings based on the type and design of the pump; as long as the correct bearing model is chosen, the shaft play has no relation to the bearings. It is related to the clearance with the balance disk, the back clearance of the impeller, etc.
There must be bearing clearance; otherwise, the bearing will overheat during operation and may burn out
This is the view from the third floor; the axial displacement of the bearings can be adjusted, and it should be done properly during maintenance!
The thrust clearance of angular contact bearings is something different from the bearing clearance
Well, that’s probably right. The explanation on Baidu is that shaft play refers to the amount of axial movement of the inner ring of a bearing relative to its outer ring
This is the clearance; after installing the two angular contact bearings, they should be able to rotate relative to each other properly, otherwise adjustments are needed
The choice of bearings is determined by the structure of the equipment. In operating equipment, there is always some shaft play, and due to differences in equipment design and industrial applications, the amount of shaft play permitted varies, which in turn determines the type of bearings that should be used.
