Bearing heating installation, this time you must pay attention to!

Rolling bearing heating heating with ( The installation of cylindrical hole bearing) By heating bearing or bearing seat, by using thermal expansion will fit into a loose fit installation method, installation method is a kind of common and energy saving. This method is suitable for interference quantity larger the installation of the bearings. Bearing heating temperature to interference for the bearing size, about the bearing before oil bath heating hot charging type or separable bearing ring uniform heating to 80 ~ 100 ℃ (in the tank Generally, bearing heated to higher than the required temperature 20 ℃ ~ 30 ℃, so that the operation process of inner ring not prematurely cooling) , do not heat the bearing more than 120 ℃, 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, after the bearing cooling axial fastening, in case the clearance between inner ring and shoulder. 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. With heating tank bearing and application in at a certain distance from the bottom of a mesh ( As shown in figure 2 7) , or hanging hooks in the bearing, bearing cannot be on the bottom, to prevent precipitation 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 of the bearings effect, reduce the hardness of the ring. Induction heating in addition to hot oil methods for hot charging, you can also use electromagnetic induction heating device for heating. The method using the electromagnetic induction principle, after electrify, under the effect of electromagnetic induction, the current to be heating body ( Bearing) , the heat generated by the bearing its own resistance. Therefore, electromagnetic induction heating method in terms of relative oil heating method has a lot of advantages: short heating time, heating uniformity, can timing and constant temperature, clean and no pollution, high efficiency, simple operation and fast.
