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. |
