Prolong the service life of TIMKEN bearing installation from the beginning

The stand or fall of TIMKEN bearing installed or not, will influence the accuracy, bearing life and performance. Therefore, please fully study the installation of the bearings that carried out in accordance with the operating standards including the following items, please TIMKEN bearing installation. 1, clean the TIMKEN bearings and related parts, ( To have grease lubrication of the bearing and oil seal or dust cover on both sides, seal bearing without cleaning before installation. ) 2, check the size of the related parts and finish 3, installation method of TIMKEN bearing installation should be according to the bearing structure, size and cooperate with properties of bearing parts, pressure should be directly in the tight fit on the ring width, shall not be passed on roller pressure, bearing installation commonly adopt the following methods: a. Force fit TIMKEN bearing inner ring and shaft tight fit, outer ring and bearing hole is a loose fit, can press the TIMKEN bearing to be pressed on the shaft, then put the shaft together with the TIMKEN bearing load bearing hole, when pressed on the TIMKEN bearing inner ring end face, cushion the assembling casing made of a soft metal materials ( Copper or mild steel) 。 TIMKEN bearing outer ring and bearing hole tight fit, inner ring and the shaft is a loose fit, TIMKEN bearings can be pressed into the bearing hole first, then assembling casing diameter should be slightly less than the diameter of a hole. If the TIMKEN 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。 Heating with heating by TIMKEN 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 TIMKEN bearing installation, the TIMKEN 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. TIMKEN bearing outer ring and light metal TIMKEN bearing seat tight fit, by heating the hot charging method of the bearing, can avoid the mating surface scratch. Tank heating TIMKEN bearings, due at a certain distance from the bottom of a mesh, or hanging hooks in the bearing, TIMKEN bearing cannot be on the bottom, in case of heavy impurities into the TIMKEN bearings 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 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 TIMKEN bearing is easy to install, two-way bearing axial spring should be fixed on the shaft, in order to prevent the relative to the axis of rotation. TIMKEN bearing installation method, usually is the situation of the axis of rotation, so the inner ring cooperate for win cooperate with shaft, with the TIMKEN bearing outer ring and bearing chamber for clearance fit.
