Rounding IKO bearing installation of the key steps in detail

Often use IKO bearing friends all know that the stand or fall of rolling bearing installed or not, will influence the accuracy, bearing life and performance. Therefore, please fully study the installation of the bearings that please follow the steps including the following items for bearing installation. ( A) Grease lubrication, cleaning bearings and related parts for bearing and oil seal or on both sides of the dust cover, seal bearing without cleaning before installation. ( 2) , check the size and finishing of the parts ( 3) , installation method of bearing installation should be according to the bearing structure, size and cooperate with properties of IKO bearing parts, pressure should be directly in the tight fit on the ring width, shall not be passed on roller pressure, rolling bearing installation commonly adopt the following methods: A. 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) , the inner diameter of the casing assembly should be slightly larger than the diameter of a journal, outside diameter than the bearing inner ring guard slightly smaller, in order to avoid pressure in keeping the frame. Rolling 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 IKO 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. B。 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 IKO bearing installation, 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. Rolling 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. C。 The installation of the cone bearing cone hole can be directly installed in a shaft with taper bearing neck, or load set set of the cone, and the withdrawal of the tightness of cooperate, IKO bearing radial clearance reduction is available to measure, therefore, before installation should be measured rolling bearing radial clearance, the installation process should often measure the clearance in order to meet the need of clearance reduction is, commonly used while installing lock nut installation, also can adopt the method of heating installation. D。 The installation of the thrust bearing thrust bearing of the matching of the thorough and axis is commonly transition fit, seat and the bearing holes with the general for the clearance fit, so the IKO bearing is easy to install, two-way thrust bearing axial spring should be fixed on the shaft, in order to prevent the relative to the axis of rotation. Bearing installation method, usually is the situation of the axis of rotation, so the inner ring cooperate for win cooperate with shaft, rolling bearing outer ring and bearing chamber for clearance fit.
