What are the characteristics of rolling bearing and sliding bearing match?

Sliding bearing ( slidingbearing) Work under sliding friction bearings. Sliding bearing work stable and reliable, no noise. Under the condition of the liquid is smooth, smooth appearance is sliding oil separately without direct contact, still can greatly reduce the wear of friction loss and appearance of oil membrane also has a certain vibration absorbing ability. But starting frictional resistance is bigger. Shaft is locally referred to as the journal bearing, and shaft neck matching parts called bush. In order to improve the friction properties of bearing bush appearance in its appearance cast anti-friction material layer is called the bearing bush. Bearing and the bearing bush data collectively known as the sliding bearing. The commonly used sliding bearing has a bearing alloy ( Also called babbit or white metal) , wear resistant cast iron, copper and aluminum alloy, powder metallurgy materials, plastics, rubber, hardwood and carbon - Graphite, ptfe ( PTFE） , modified polyformaldehyde ( POM） , etc. Sliding bearing ordinary application places under the condition of low speed and heavy loading conditions, or the maintenance of remaining oil and charging smooth hard operating area. Rolling bearings will run between shaft and shaft seat sliding friction into rolling friction, thereby reducing friction losses of an elaborate machinery components, called rolling bearing ( rollingbearing) 。 Rolling bearing by the outer ring, inner ring, rolling body and adhere to the frame. The inner ring is used together with suitable merger and axis rotation, outer ring is used to match the bearing seat, a support role, rolling body is with the aid of a stick to frame an average will spread between inner ring and outer ring, roller its appearance size and number directly affects the using performance and life of rolling bearings, adhere to the average spread frame can make the roller, avoid rolling body is shattered and guide roller rotation smooth effect. The rolling bearing and sliding bearing compare to what are the characteristics? Rolling bearing using maintenance lunch, work reliable, starting performance is good, in the medium to high under the weight. Compared with sliding bearing, roller bearing radial size is larger, vibration reduction ability is poorer, high speed when life is low, the sound is bigger. The centripetal bearing of rolling bearing ( Mainly accept radial force) Usually consists of inner ring and outer ring, rolling body and rolling body frame 4 local composition. Inner ring tight set on the shaft neck and with shaft rotation, outer ring is installed in the bearing hole. Within the peripheral and outer ring, ring week all have a race. When the relative rotation on inner and outer, namely, outer ring rolling on the rolling roller, they are separated by insist on frame, prevent rub against each other. Thrust bearing ring and two local living circle. Ring and shaft sleeve, living circle bearing on the bearing seat. Ring and rolling body usually adopt high strength, good abrasion resistance of rolling bearing steel manufacture, the appearance after quenching hardness should reach HRC60 ~ 65. Adhere to the multi-purpose made from mild steel stamping, also can use copper alloy fabric bakelite and plastic manufacturing. Rolling bearing and sliding bearing first appearance on the structure, the difference between a rolling bearing is supported by the rotation of the roller axis of rotation, so the contact area is a point, the more rolling body, nine more contact point; Sliding bearing is to rely on a smooth surface to support the axis of rotation, so the contact area is a plane. Followed by movement in different ways, the movement of the rolling bearing way is rolling; Sliding bearing is sliding movement way, so there are complete different friction on the situation.
