How to install the motor bearing?

Jiaxing bearings are widely used in motor industry, motor bearing installed or not, good or bad will directly affect the accuracy, bearing life and performance. Therefore, we should fully study the installation of the bearings, so how to properly installed? Jiaxing bearing group to lead everybody to learn together. one Force fit tight fit bearing inner ring and the shaft, the outer ring and bearing hole is a loose fit, press the bearing to be pressed on the shaft are available, and then put the shaft together with the bearing load bearing hole, when pressed on the bearing inner ring end face, cushion the assembling casing made of a soft metal materials ( 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. two Heated by heating the bearing or bearing seat, the use of 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 bearing, the bearing before hot charging type or separable bearing ring into the fuel tank 80 - uniform heat 100 ℃, and then loaded on the shaft, as soon as possible out of the oil to prevent inner ring after cooling end face and shoulder joint is not tight, bearing axial fastening again after cooling. 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. Motor bearing installed correctly is the premise and guarantee for normal operation of the bearing users should refer to the installation method, operating under the professional technical guidance. Jiaxing bearing group sales co. , LTD is in province set up a marketing center of jiaxing bearing group, a professional engineers, technical guidance, to provide customers free bearing design selection, fundamentally solve the difficulty selection, welcome your inquiry, we will serve you wholeheartedly.
