Considering the friction loss of graphite copper sleeve, the smaller the friction coefficient of bearing material, the better. Graphite has the wear coefficient of excellent steel sleeve lubricated bearing. So, what should be paid attention to when installing graphite copper sleeve?
From the structure point of view, graphite is a solid material, which can be lubricated without oil, reduce the graphite inlaid lubrication, and reduce the lubrication system of bearings, so as to reduce the failure rate. Graphite has high chemical stability.
Distinguish the tight ring and loose ring of the bearing, and judge according to the inner diameter of the bearing, and the hole diameter difference is 0.1-0.3mm.
The static parts of the mechanism, that is, the parts that do not move, mainly refer to the assembly. In any case, the loose ring of the bearing should always rest on the end face of the stationary part.
Graphite copper sleeve is cheap and versatile. If metal is used as bearing, according to the situation of graphite bronze bearing, it is necessary to operate at high temperature. It is obvious that ordinary materials are not good. Materials with high temperature strength still need to be customized. The price is not several times, tens of times or hundreds of times. First of all, the materials are not easy to find.
