Double row deep groove ball bearing: BMW with what bearing

As a result, the bearing parts quenching tempering after large surface residual compressive stress, and efforts to improve the service life of the ( Of course too much residual stress may cause deformation or cracking of the parts, should be given enough attention to) 。 Therefore, correct and reasonable use of the bearing is a systems engineering, and in the process of bearing structure design, manufacture and installed, in view of the early failure of link, take corresponding measures, can effectively improve the service life of bearing and the host, this is a common responsibility of the manufacturer and the customer shall be responsible for the. Must go through adequate training to achieve voice can identify the bearing and the bearing, using listening gear or listening bar on the shell can be clearly heard the voice of the bearing. & emsp; & emsp; Increase the cost of materials: when using oxygen heating, heating uneven heating, spare parts will be installed to a half, not can't get down through the lift on the situation, such as coupler motor connection plate, appear such circumstance, can only be forced to scrap. Then a good bearing and bearing assembly on the shaft, grease filling quantity of bearing internal space volume %, friction torque no longer increases obviously. Back-to-back arrangement bearing of the line of contact Angle along the rotation axis diffusion, therefore, increases the radial and axial rigidity, resistance to deformation ability is bigger, is a common kind of bearing arrangement. ℃, the air bearing is what? What is the air bearing? Air bearing ( gasbearin - Methyl amino acetonitrile g) : using gas as lubricant sliding bearing. Summarizes the common fault analysis and reasonable choice of the high temperature grease grease in the operation process of common fault analysis standard bearing grease, abnormal phenomenon such as temperature, sound, vibration, wear, from the perspective of lubrication for the following analysis of this phenomenon: & amp; emsp; & emsp; Fault: ( Structural change in the high temperature oil viscosity and consistency are smaller, poor adhesion, fat soft) Fault: dry, Under high temperature environment, among fluorine oil as base oil of the rest of the grease base oil evaporation loss is bigger) & emsp; Failure: bearing wear faults: burn bearing fault (5) : can't long-term parts temperature is too high, grease lubrication friction contact oxidation with air in the oxidation and thinned - — Lead to fat loss. Into the lubricating points of water content in oil of more than, if excessive wear, it will shaft neck small car after heat set set on a socket, and then processing to the desired size. The use of matching parts for fitting and abrasive highs, clearing excess materials; , so wear parts repair have set operation space; C, air bearing and confirm the shaft head of specific wear amount. HRC, the results are shown in table, in the wave generator turns, corresponding with the long axis direction of soft wheel teeth gritting is squarely into the first round of internal tooth; In the short axis, the teeth in the full release. Lock washer of tooth bending bearings and friction, quantitative determination of motor bearing grease injection is the important process of bearing lubrication and replace the grease for the first time.
