Structural characteristics of tapered roller bearing

The type of tapered roller bearings is 30000, tapered roller bearings are separable bearings. Generally, one hundred percent can be used interchangeably between the outer ring and the inner components of the tapered roller bearing in the range of dimensions involved in the tolerance of the GB/T307.1-94 rolling bearing centripetal bearing.
The angle of the outer ring and the diameter of the raceway are standardized with the same size. It is not allowed to change at the time of design and manufacture. The outer ring and inner components of the tapered roller bearing can be exchanged all over the world.
Tapered roller bearings are mainly used to bear radial load combined with radial load. Compared with angular contact ball bearings, the bearing capacity is high and the limit speed is low. Tapered roller bearings can withstand axial loads in one direction, which can restrict the axial displacement of the shaft or shell in one direction.

Conical roller bearing bearing joint load

Tapered roller bearings are separable bearings, bearing inner and outer rings have conical raceway. According to the number of rollers, the bearings are divided into single row, double row and four row tapered roller bearings. Single row tapered roller bearings can withstand radial loads and uniaxial axial loads. When the bearing is subjected to radial load, an axial component will be generated, so it is necessary to balance the bearing when another bearing that can bear the reverse axial force is needed.
Tapered roller bearings refer to radial thrust bearings with rolling bodies as tapered rollers. There are two kinds of small cone angle and big cone angle. The small cone angle is mainly subjected to radial and axial joint loads based on radial load, which is often used in double use, reverse installation, internal and external seats can be installed separately, and the radial and axial clearance can be adjusted in the installation and use. The big cone angle is mainly subjected to axial and radial joint loads mainly with axial load, which is generally not used alone to bear pure axis. The load can be used as a pair of configurations (relatively installed at the same name) to withstand pure radial load.

Installation method of deep groove ball bearing

Deep groove ball bearing installation method 1: pressure entry coordination: bearing inner ring and shaft tight fit, when the outer ring and bearing seat holes are loosely matched, the bearing first is loaded on the shaft with the press, then the shaft together with the bearing is loaded into the bearing seat hole, the assembly sleeve is made of a soft metal material on the face of the inner ring of the bearing. (copper or soft steel), the bearing outer ring is tightly matched with the bearing seat hole. When the inner ring is loosely matched with the shaft, the bearing can be pressed into the hole of the bearing seat. The outer diameter of the assembly sleeve should be slightly smaller than the diameter of the seat. If the bearing ring is tightly matched with the shaft and the seat hole, the installation room and the outer ring should be pressed into the shaft and the seat hole at the same time. The supporting pipe structure should be able to simultaneously tighten the bearing inner ring and outer ring end face.
Deep groove ball bearing installation method two: heating coordination: by heating the bearing or bearing seat, using thermal expansion to transform the tight fit into a loose fitting method. It is a common and labor-saving installation method. This method is suitable for the installation of large interference bearing, and the bearing or detachable bearing rings are put into the tank before hot loading. Heating 80-100 centigrade, then removed from the oil to the shaft as soon as possible, in order to prevent the inner end of the inner ring and the shaft shoulder close after cooling, the bearing can be tightened again after cooling. When the bearing outer ring is tightly matched with the bearing seat made of light metal, the hot loading method of the heating bearing seat can be used to avoid the abrasion of the matching surface. When heating bearings in the tank, there should be a grid at a distance from the bottom of the box, or the bearing is hung with a hook. The bearing can not be placed on the bottom of the box to prevent the impurity from entering the bearing or the uneven heating. The thermometer must have a thermometer in the tank, and the temperature of the oil must not exceed 100 degrees, in order to prevent the tempering effect and make the ring. The hardness is reduced.

Working principle and characteristic of deep groove ball bearing

Working principle
Deep groove ball bearings mainly bear radial load, and can also bear radial load and axial load. When it only bears radial load, the contact angle is zero. When the deep groove ball bearing has large radial clearance, it has the performance of angular contact bearing, which can bear large axial load. The friction coefficient of deep groove ball bearing is very small and the ultimate speed is very high.
Bearing characteristics
Deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple and easy to use. It is mainly used to bear radial load, but when the bearing radial clearance is increased, it has the performance of a certain angular contact ball bearing, which can bear the joint load of the diameter and the axial direction. When the speed is high and the thrust ball bearing is not suitable, it can also be used to bear pure axial load. Compared with other bearings of the same size as deep groove ball bearings, this type of bearing has small friction coefficient and high limit speed. But it is not resistant to impact and is not suitable for heavy load. [2]
After the deep groove ball bearing is mounted on the axis, the axial displacement in the two directions of the shaft or shell can be restricted within the axial clearance range of the bearing, so the axial orientation can be made in the direction of the axial direction. In addition, this kind of bearing has a certain ability to adjust the heart. When it is 2 '~ 10' relative to the shell hole, it can still work normally, but it has a certain effect on the bearing life.
