What are the structures of journal bearings, rolling bearings or plain bearings?
As far as I know, there seems to be no uniform standard in our country at the moment. So I'm sorry, but I still can't provide you with the organization chart. Supplement:Disclaimer: my previous answer was mixed and invalid!!! Totally agree with the frozen answer!!!Today's journal bearings are mostly used in the field of automobile technology.
The general structure is as follows: one hole, one shaft, clearance fit, the hole is tile, and the shaft is neck. Because the sliding bearing, there are strict requirements, high lubrication, so between the tile and the strength for high pressure hydraulic lubrication, the shaft does not contact the process of turning the shaft neck quickly, as far as possible to achieve zero wear in the ideal. Sarah's testimonials:
The structure of journal bearing is similar to that of deep groove bearing. Most of the applications are radial load bearing, and the shaft is often very short, and even the inner ring is directly connected with the inner ring of the bearing. Some outer ring in accordance with the shape of the machine tool rail surface. The name of the journal bearing probably comes from this!
