Single row single bearing knowledge the first lecture

Single row single bearing knowledge the first lecture: 1. Single row deep groove ball bearing is the most common type of rolling bearing. They use are very common. The inner ring and outer ring of the rolling channel slot has a circular arc. Radius is larger than the ball. In addition to the radial load, can also be applied axial load. In any direction. Due to its low torque, spherical roller bearing is very suitable for high. Speed and low power consumption is required. In addition to the open bearing, these bearings are usually equipped with steel plate or rubber seals. On one side or both sides, lubricating grease. In addition, sometimes use buckle. The periphery. As to the cage, steel is the most common. 2. Single row deep groove ball bearing internal channel of the magnetic bearing deep groove bearings bearing slightly than shallow. Since the outer ring is only one side shoulder, outer ring can be removed. It is often good for installation. In general, duplex duplex USES two such bearings. Magnetic bearing is a kind of 4 to 20 mm diameter small bearings, mainly used for small bearings. Magneto, gyroscope, instruments and other commonly used copper alloy stamping cage. Magnetic bearing in this type of independent bearing can bear radial load and axial load. Direction. 15° ,25度; ,30度; 40度; Four kinds of contact Angle are available. The larger the contact Angle, the axial bearing capacity is higher. However, for high speed operation, the smaller the contact Angle. Give priority to. Usually, the two bearings for duplex, and the gap between them. Must be properly adjusted. But, for the high contact Angle of precision bearing, usually using pressure steel cage. Less than 30 & deg; Cage, nylon resin is often used. 3. Angular contact ball bearing the combination of the two radial bearings called duplex. Usually, they are formed with Angle. Contact ball bearing or tapered roller bearing. Possible combinations including face to face, one of the outer face ( DF type) , back to back, The DB) , or both in the same direction (positive Type DT) 。 DF and DB double bearing can bear radial load and axial load. Any direction loading. Type when DT is used, there is a direction of axial load is very strong, it is necessary to impose equal load on each bearing conditions
