The difference between sliding bearing and rolling bearing lubrication and maintenance methods

Sliding bearing (sliding bearing), bearing in sliding conflict operations. Bearing smooth operation, reliable, no noise. In the composite bearing body fluid lubrication, lubricating oil is separated by a sliding look without the risk of direct touch touch, but also can greatly reduce the loss and the appearance of conflict of wear, the film also has a certain vibration absorption ability. But starting a conflict greater resistance. Bearing part of the shaft is called the journal, and the journal fit the part called bush. In order to improve the nature of conflict bush bearing red appearance and on the inside of the outer casting antifriction bearing bush called the data layer. Bearings and bearing liner materials collectively known as the sliding bearing material. Common sliding bearing materials bearing alloy (also known as white metal or babbitt), cast iron, copper and aluminum alloy, powder metallurgy materials, plastics, rubber, hardwood and carbon - graphite, polytetrafluoroethylene (PTFE ), modified POM (POM), and the like. Bearing in low-speed applications are generally heavy working conditions or the protection and conservation of filling oil difficult job site.
The slide-axis and the axis of the conflict between the seat becomes tumbling conflict, thereby reducing conflict lost a fine mechanical components, called rolling bearing (rolling bearing). Rolling bearings generally by the outer ring, the inner ring, rolling body and the holding structure into. During the effect of the inner ring rotates together with the shaft fit combined with the shaft and the bearing outer ring effect is like a complex, supportive effect, roll cage body by means of a uniform spread of the rolling bodies between the inner ring and the outer ring its shape and size and the number of direct impact on the use of performance and life of rolling bearings, make the roll cage body spread evenly, preventing the falling body roll, guide roll rotational lubrication effect.
Rolling bearings facilitate the use of protection, reliable operation, good starting performance, at moderate speeds higher carrying capacity. Comparison with the sliding bearings, radial rolling bearing large size, to poor damping, high-speed, low life, a larger movement. The rolling bearing radial bearings (primary support radial forces) generally consists of an inner ring, an outer ring, rolling body and the body roll cage four points constitute. Together with the inner sleeve and the shaft is rotated in the journal, the outer ring mounted in the housing bore. The inner periphery of the inner ring and the outer ring on the outer periphery formed with a raceway. When the inner and outer rings relative roll, namely roll body including the outer ring raceway rolling, they are separated from the cage to prevent conflict with each other. Thrust bearing live ring and a tight circle divided into two parts. Tight circle with the sleeve tight, live ring bearing in the bearing housing. Rings and roll bodies are generally selected high strength, good wear resistance of rolling bearing steel production, the appearance of hardness after quenching should reach HRC60 ~ 65. Cages are mostly made of mild steel stamping, you can also use copper alloy folder cloth bakelite or plastic production.
Rolling and plain bearings first appearance of differences in the structure, rolling bearings rely roll body roll to support the roll axis, so part of it is a touch point, the more body roll, nine more touch points; sliding bearings rely on the smooth surface to support the roll axis, so part of it is touching a surface. Second method is not the same movement, the movement method of rolling bearings are rolling; a sliding movement of the sliding bearing, so the conflict situation also completely different.
