Other installation method of deep groove ball bearing

Heating fit. By heating bearing, using thermal expansion will fit into a loose fit installation method, which is a kind of common and energy saving. This method is suitable for interference quantity larger the installation of the bearings. The bearing before hot charging type or separable bearing ring into the fuel tank even heat 80-100 ℃, and 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, axial bearing cool can be tighten. Bearing outer ring and light metal bearing seat tight fit, by heating the hot charging method of the bearing, which can avoid the mating surface scratch. Heating tank with bearing should be at a certain distance from the bottom of a mesh, 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 controlling the oil temperature so that it should not exceed 100 , in order to prevent the tempering effect, reducing the hardness of the ring.
