The introduction of rolling mill bearing

Rolling mill bearing ( 轴承) Usually only used to bear radial load, compared with the same size deep groove ball bearings, have bigger radial load capacity, speed limit ( 转速) Close to deep groove ball bearings, but with this type of bearing hole of shaft, shell processing the demand is higher, allow the axis of the inner ring and outer ring axis inclination is small ( 2° - 4° ） , two axis tilted as beyond the limits, roller and ring raceway contact ( 条件) Will deteriorate, seriously affect the bearing load capacity, reduce the use of the bearing ( 使用) Life ( 一生) 。 Thin wall bearing manufacturer for bearing low friction torque, high rigidity, good rotation accuracy, using the small diameter steel ball. The use of hollow shaft, ensure the lightweight and wiring of the space. Thin wall type bearing has realized the extremely thin cross section of the bearing, also has realized the product miniaturization, lightweight. The diversity of products extends its application scope. So if need these bearings are installed in the axial load effect under the host components ( 装配单元) , only use other types of bearing at the same time under the premise of to bear axial load, just can use. Generally described bearing ( 轴承) For the rolling bearing ( 球滚子轴承) 。 Rolling bearing is running between the shaft and the shaft seat sliding friction into rolling friction, thereby reducing friction loss ( 损失) A kind of precision, precise) The machinery ( 机械) Components. Generally by the outer ring, rolling bearing inner ring, rolling element and cage. Rolling bearings use ( 使用) Convenient maintenance, reliable, starting performance ( 兴能) Well, carrying capacity is higher under the moderate speed. Compared with sliding bearing, roller bearing radial size is larger, vibration reduction ability is poorer, high-speed life ( 一生) Low, noise is larger. The centripetal bearing of rolling bearing ( Mainly bear radial force) Usually consists of inner ring and outer ring, rolling body and rolling body cage of four parts. Thin wall bearing manufacturer for bearing low friction torque, high rigidity, good rotation accuracy, using the small diameter steel ball. The use of hollow shaft, ensure the lightweight and wiring of the space. Thin wall type bearing has realized the extremely thin cross section of the bearing, also has realized the product miniaturization, lightweight. The diversity of products extends its application scope. Inner ring tight set on the shaft neck and with axis rotation ( 旋转) , 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 the cage, avoid rubbing against each other. Thrust bearing ( 轴承) Ring and the living circle. Ring and shaft sleeve, living circle bearing on the bearing seat. Ring and rolling body usually adopt intensity ( 强度) High, good abrasion resistance rolling bearing steel manufacturing, quenching ( 崔huǒ) After the surface hardness should reach HRC60 ~ 65. Maintains a multi-purpose made from mild steel stamping, also can use copper alloy fabric bakelite or plastic ( Structure: synthetic resin, plasticizer, stabilizer, pigment) Such as manufacturing.
