jxkj deep groove ball bearing installation methods -币游国际app

method one: force fit: and shaft tight fit, outer ring and bearing hole is a loose fit, available press the bearing pressure equipment in the shaft first, and then, axis along with the deep groove ball bearing, insulation 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 hole first, then assembling casing diameter should be slightly less than the diameter of a hole. if the bearing ring and shaft and hole is a tight fit, install indoor ring and outer ring to pressure into the shaft and hole, at the same time assembling casing structure should be able to at the same time, so the bearing inner ring and outer ring end face.

method two: heating cooperates: or bearing seat, by heat using thermal expansion will fit into a loose fit method of installation. installation method is a kind of common and energy saving. this method is suitable for interference quantity larger the , the bearing before hot charging type or separable bearing ring into the fuel tank even heat 80-100 ℃, and then loaded on the shaft, as soon as possible out of the oil to prevent inner ring after cooling end face and the shoulder joint is not tight, to axial bearing cooling can then tighten. bearing outer ring and light metal bearing seat tight fit, by heating the hot charging method of the bearing, can avoid the mating surface scratch. 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, 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.
