Structure and characteristics of spherical roller bearing

wallpapers Products 2021-08-23
The spherical roller bearing is composed of an outer ring with a spherical raceway, a double raceway inner ring, one or two cages and a group of spherical rollers. Since the center of the outer ring spherical raceway is consistent with the center of the bearing, it has spherical performance, and can automatically adjust the inclspherical roller bearingtion or shaft deflection caused by the angular error between the shaft and the bearing seat.
Structure and characteristics of spherical roller bearing
Spherical roller bearings are divided into cylindrical holes and tapered holes. The taper of the tapered hole is 1:12, and the spherical roller bearing with descendant number k is 1:30, and the spherical roller bearing with descendant number K30 is 1:30. The inner hole is a bearing with a conical hole, which can be directly installed on the conical shaft. When the bearing is matched with the conical shaft, the radial clearance of the bearing can be adjusted by moving the inner ring along the axial direction; Or use an adapter sleeve or a removal sleeve to install the cylindrical shaft.
According to whether the inner ring has ribs and the use of the cage, it can be divided into C type and Ca type. There is no rib on the inner ring of the C-type bearing and there is a stamped steel plate cage. CA type-bearing inner ring has ribs on both sides and adopts a solid cage made of the automobile. For convenient and simple lubrication, the spherical roller bearing can be provided with lubrication holes and lubrication grooves, and the outer ring is provided with lubrication grooves and three lubrication holes. The last code is W33. Spherical roller bearing can bear a large radial load and bidirectional axial load. It is especially suitable for load-bearing load or impact vibration load. However, the allowable working speed of spherical roller bearing is relatively low.
Axial clearance procedure for installing spherical roller bearings
The installation axial clearance of spherical roller bearing can be adjusted by adjusting nut, adjusting gasket on the journal, thread in bearing seat hole or pre tightening spring. The size of the axial clearance is related to the arrangement of bearing installation and the distance between bearing and shaft and bearing seat materials, which can be determined according to working conditions. The spherical roller bearing has a high load and high speed. The effect of temperature rise must be considered. The axial clearance must be adjusted. The temperature rise caused by the reduction of clearance should be estimated, that is, the axial clearance should be adjusted appropriately, which is a little large. For low-speed bearings and bearings with bearing vibration, they shall be installed without clearance or with preload. Its purpose is to make the roller and raceway of spherical roller bearing have good contact and uniform load distribution, so as to prevent the roller and raceway from being damaged by vibration and impact. After adjustment, check the axial clearance with a dial indicator.
