3, bearing installation method should be installed in accordance with the nature of the bearing structure, size and bearing member may be bearing pressure should be directly added to the tight fit of the ferrule end face may not pass through the rolling pressure, bearing installation generally use the following method : A, press-fit bearing inner ring and the shaft is a tight fit, the outer ring of the bearing hole is relatively loose fit, can be pressed to press the bearings on the shaft bearings with seal engraving machine, and then along the shaft along with bearing Load bearing hole. When the pressure mounted on the inner end surface of the bearing pad, a soft metal material of the mounting sleeve "copper or soft steel." The inner diameter of the sleeve assembly should be slightly larger than the journal diameter, outer diameter should be slightly smaller than the diameter of the bearing inner wall, in order to avoid pressure in the cage. Bearing outer ring and the bearing hole cutters bearing tight fit V grooved belt apron 6005, when 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 slightly less than the diameter of the housing bore. If the bearing ring and the housing bore and shaft are a tight fit when installing inner and outer rings to be pressed into the shaft and housing bore, the assembly casing shall be constructed simultaneously pressing the bearing inner and outer end faces thrust comprehensive and shaft bearings with thrust bearing is usually installed with the transition, with the race and the bearing hole is generally clearance fit, so the bearing is easier to install, two-way thrust bearing spring should be fixed to the shaft axis, to prevent relative rotation of the shaft. Bearing installation method, under normal circumstances is the case of the rotation axis of the majority, and therefore with the axis of the inner ring and had to win with, with the bearing outer ring and bearing housing clearance fit. Fourth, check the bearing installation of five, adding high-speed precision angular contact ball bearing installation lubricants: High-speed precision angular contact ball bearings, high-speed rotation of occasions mainly used to carry lighter 7002 / P4 7005 / P4, it requires precision bearings High speed, low vibration and low temperature rise limited life. Often high-speed spindle bearing installed in pairs, the inner surface grinding machine spindle speed key component parts. The main technical indicators: 1. Bearing precision index: more than GB / 307.1-94 P4 level precision 2. High-speed performance: dmN value of 1.3 ~ 1.8x 106 / min 3. life (average):> 1500 h high-speed precision angular contact ball bearing life of a great relationship with the installation, 7002 / P4 7005 / P4, Shun GF bearing Electrical (certified), provided by the Shenzhen City, Guangdong Development Bearings Electrical Co., Ltd..
