Overview of deep groove ball bearings
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 loads, but when the radial clearance of the bearing is increased, it has certain performance of angular contact ball bearings and can bear radial and axial combined loads. 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 types of deep groove ball bearings with the same size, this kind of bearings have small friction coefficient and high limit speed. But not resistant to impact, not suitable for bearing heavy loads.
Deep groove ball bearings installed on the shaft, in the axial clearance range of the bearing, can limit the axial displacement of the shaft or the shell in two directions, so it can be used for axial positioning in both directions. In addition, this kind of bearing also has a certain self-aligning ability, when it is tilted 2 '~ 10' relative to the shell hole, it can still work normally, but it has a certain influence on the bearing life.
The first installation method of deep groove ball bearing
Pressing fit: Bearing inner ring and shaft tight fit, outer ring and bearing hole is a loose fit, press the bearing to be pressed on the shaft are available, and then put the shaft together with the bearing load bearing hole, when pressed on the bearing inner ring end face, cushion the assembling casing made of a soft metal material (copper or mild steel), bearing outer ring and bearing hole tight fit, inner ring and the shaft is a loose fit, The bearing can be pressed into the bearing seat hole first, then the outer diameter of the assembly sleeve should be slightly smaller than the diameter of the seat hole. If the bearing ring is closely matched with the shaft and the seat hole, the inner ring and the outer ring should be pressed into the shaft and the seat hole at the same time, and the structure of the assembly sleeve should be able to hold the end face of the inner and outer ring of the bearing at the same time.
The second installation method of deep groove ball bearing
Heating fit: by heating the bearing or bearing seat, the use of thermal expansion to change the tight fit into loose fit installation method. It is a common and labor-saving installation method. This method is suitable for the installation of bearings with large interference. Before hot loading, the rings of bearings or separable bearings are put into the oil tank and heated evenly at 80-100℃, and then removed from the oil and installed on the shaft as soon as possible. In order to prevent the inner ring end face and shaft shoulder from fitting tightly after cooling, the bearings can be tightened axial after cooling. When the outer ring of the bearing is closely matched with the bearing seat made of light metal, the heating method of the bearing seat is adopted to avoid the abrasion of the mating surface. Heating tank with bearing and should be at a certain distance from the bottom of a mesh, or hanging hooks in the bearings, bearing on the bottom, in case of heavy impurities into the bearing or uneven heating, the fuel tank must have a thermometer, strictly control the oil temperature shall not exceed 100 ℃, in order to prevent the tempering effect, reduce the hardness of the ring.
