angular contact ball bearing installation instructions company 双列角接触球轴承|3056轴承-pg电子官方网站

    angular contact ball bearings installed good or bad, will affect the accuracy of the life and performance of the bearing. so, please install the full study bearing that follow the operating standards, including the following items be included bearing installation.
     1, cleaning bearings and related parts (already greased bearings and seals before a bilateral or shield, seal bearing installation without washing.)
     2. check the size and finishing the relevant parts
     3, angular contact ball bearing installation method should be installed in accordance with the nature of the bearing structure, size and bearing components may be, the pressure should be directly added to the ferrule end face of a tight fit too, shall pass through the rolling pressure, bearing installation generally use the following method:
     a. the press-fit
     bearing inner ring and the shaft so that a tight fit, the outer ring and the bearing bore is relatively loose fit, can press the bearings would be pressed onto the shaft, and the shaft together with the bearing together with the load bearing hole, when the pressure mounted the end face of the bearing inner ring, a soft metal material of the pad assembly of the sleeve (copper or mild steel).
     angular contact ball bearing outer ring and housing bore a tight fit, while the inner ring and the shaft is relatively loose fit, the bearing can be pressed into the bearing hole, then assemble the outer diameter of the sleeve should be slightly smaller than the diameter of the housing bore.
     if the bearing rings and the shaft and the housing bore is a tight fit, the outer ring is installed to the indoor coil and simultaneously pressed into the shaft and the housing bore, the assembly structure of the casing should be able to simultaneously charge the end face of the bearing inner ring and the outer ring tightly.
     b. heating tie
     by heating the angular contact ball bearings or bearing, the use of thermal expansion will tight fit into a song with the installation method. is a common and effortless installation method. this method is suitable for a large amount of interference bearing installation, pre-heat loading of the bearings or separable bearing rings into the tank uniform heating 80-100 ℃, then remove from the oil loaded onto the shaft as soon as possible, in order to after cooling to prevent the inner face and shoulder fit is not tight, you can then tighten the rear bearing axial cooling. when the bearing outer race and light metal tight fit, using heat bearing thermal loading method to avoid mating surface by abrasion.
     when the tank is heated with angular contact ball bearings, at a certain distance from the bottom of the gate should network, or with a hook hanging bearings, can not be put on the bottom to prevent heavy impurities entering the bearing or uneven heating, the tank must be a thermometer, a strict control of the oil temperature must not exceed 100 ℃, in order to prevent tempering effect, reduces the hardness of the ferrule.
