Description
Technical field
The invention belongs to technical field of bearings, more particularly to a kind of thin-walled of the sliding bearing of supporting rod rotor is split
Formula bearing shell.
Background technology
Bearing shell is the part of sliding bearing contact axle journal, is generally made of wear-resistant materials such as bronze, antifriction alloys, special
In the case of, it can be made of timber, plastics or rubber.Split bushing includes top bearing shell and lower bearing, between bearing shell and axle journal
Oil film is formed to maintain the bearing between axle journal and bearing shell and lubrication, while bearing shell needs progress axial and circumferential can in bearing block
By positioning, circumferentially retention Hp or passes through positioning pin or limit screw generally by bearing shell outer wall and realizes, on the one hand,
If processing retention Hp or pin hole, bearing shell need to execute punching press or extruding so that the dimensional stability of bearing shell it is difficult to ensure that, for
Thin-wall bearing shell is not easy to processing limit screw slot；On the other hand, for split bushing, it is also necessary to which additional cooperation makes bearing shell
It is reliably fixed in bearing block, it is troublesome in poeration.
