Installation method of deep groove ball bearing

Deep groove ball bearing installation method: a press fit: the bearing inner ring and shaft which is tightly matched with the outer ring and bearing seat hole is a loose fit, can press the bearing pressure mounted on the shaft, and the shaft together with the bearing load in the bearing hole, press in the bearing inner ring end face assembly sleeve a soft pad made of metal material (copper or steel), the bearing outer ring and bearing seat hole is tightly matched with the inner ring and shaft is a loose fit, the bearing can be pressed into the bearing hole, then the assembly sleeve diameter should be slightly smaller than the diameter of the hole. If the bearing ring with the shaft and hole seat is a tight fit, installation of interior ring and the outer ring and pressed into the shaft and hole structure, the assembly sleeve should be able to face tight and bearing inner and outer rings.

Deep groove ball bearing installation method: two with heating by heating the bearings or bearing seat, the expansion will close fit into the installation method of loose fitting using heat. Is a commonly used method for installation and labor-saving. This method is suitable for a large amount of surplus bearing installation, hot charging before the bearing or separable bearing rings into the tank uniform heating of 80-100 DEG C, then removed from the oil as soon as possible fitted to the shaft, to prevent cooling after the end face of the inner ring and shaft shoulder joint is not tight, the bearing cooling can be fastened. The axial bearing outer ring and light metal bearing tight fit, the bearing seat heating and hot charging method, can avoid mating surface by abrasion. With oil tank heating bearings, from the bottom at a certain distance should be a mesh, or with a hook hanging bearing, bearing can not be put on the bottom, to prevent the heavy impurities into the bearing or uneven heating, the tank must be strictly control the temperature thermometer, shall not exceed 100 degrees, to prevent the occurrence of the tempering effect, make the ring hardness decreased.
