Installation Method Of Deep Groove Ball Bearing
- Aug 01, 2017 -

Deep groove ball Bearing installation method One: the pressure into the match: the bearing inner ring and the shaft to make tight, the outer ring and the bearing seat hole is more loose, the available press presses the bearing first pressure on the shaft, and then the shaft together with the bearing bore in the bearing seat hole, when pressed in the bearing inner ring end face, cushion a soft metal material to do the assembly casing (copper or soft steel), bearing outer ring with the bearing seat hole tight match, the inner circle and the shaft are loose with the work, may the bearing first presses into the bearing seat hole, Then the outer diameter of the assembly sleeve should be slightly smaller than the diameter of the seat hole. If the bearing rings are tightly matched with the shaft and the seat hole, the internal ring and the outer ring shall be pressed into the shaft and the seat hole simultaneously, and the structure of the casing should be able to simultaneously fasten the bearing inner ring

Method for installation of deep groove ball Bearings II: Heating fit: By heating the bearing or bearing seat, Using thermal expansion to transform the tight fit into the installation method of loose fit. It is a common and labor-saving installation method. This method is suitable for the installation of large-scale bearings, before the hot-loaded bearing or separable bearing ring into the fuel tank evenly heated 80-100 ℃, and then removed from the oil as soon as possible to the shaft, in order to prevent cooling after the inner ring end and shaft shoulder is not tight, after the bearings are cooled, the axial fastening can be carried out again. When the bearing outer ring and the light metal bearing seat are tightly matched, the heat-loading method of the heating bearing seat can be used to avoid the abrasion of the mating surface. When you use the tank to heat the bearing, there should be a grid at a certain distance from the bottom of the box. Or with hooks hanging bearing, bearing can not be placed on the bottom of the box, in case of sinking impurities into the bearing or uneven heating, the tank must have a thermometer, strict control of oil temperature should not exceed 100 ℃ to prevent the tempering effect, so that the hardness of the ring.
