When the rotation when TIMKEN bearings, thrust ball bearing inner ring and outer ring raceway surface due to rolling is rolling contact, and thus for the dark side of the running track, running track attached to the roller surface are not unusual, this change load conditions can be learned, so when the time dismantling the bearing, please pay attention and observe strict raceway running track.
Thrust ball bearings are correctly installed, which will affect accuracy, longevity, performance. Therefore, the design and installation of the bearing assembly department to adequately studied. Hope to be installed in accordance with operating standards. Operating standards of the project is generally as follows:
(1), cleaning bearings and related components
(2), check the connected components of size and finishing of
(3), the installation
(4), check the bearings installed
(5), the supply of lubricant
Before installation in the soon to open TIMKEN bearings packed. General grease lubrication, not clean, grease filled directly. Lubricating oil, general do not have to wash, but the instrument used or high-speed bearings, etc.,
Washed clean of oil to use, remove the rust coating on the bearing agent. Remove the rust bearings rust easily, so you can not put the air. Bearing grease that had been enclosed, can not wash directly.
TIMKEN bearing installation method, due to the bearing structure, with the condition varies, generally, the more axis rotation, so the inner ring needs interference fit. Cylindrical bore bearing, multi-press push, or fitted with a thermal method. Cone of the occasion, directly mounted on taper shaft, or sleeve installation.
Installed in the shell, usually with more clearance, the outer ring had a surplus quantity, usually pressed into the press, or have installed cooling shrink fit method. With dry ice as coolant, shrink with the installation of the occasion, the air in the water will condense on the surface of the bearing. Therefore, the need for adequate corrosion protection.
If you look at the trajectory, then the burden will be that only the radial load to bear large axial load, under a moment load, or the bearing housing on the extreme rigidity inequality. You can check whether the bearing loads and with the unexpected installation error whether the country and so on, and become a loss of accountability for TIMKEN bearing clues to the cause.
