Thrust ball bearing running track installation method

When the TIMKEN bearing rotation, thrust ball bearing inner ring and outer ring raceway surface with rolling body is rolling contact, as the dark side, thus orbit trajectory are attached to the raceway surface does not belong to abnormal, the change can be learned that load conditions, so when remove the bearing, please keep close attention and observation on the surface of the raceway. The installation of thrust ball bearing is correct, affects the precision, life and performance. Therefore, design and assembly department for the installation of the bearing be fully studied. Hope to work in accordance with the standards for installation. Operation standard project usually is as follows: ( 1) , clean bearings and bearing components (associated 2) And check the size of the interrelated parts and finish machining condition ( 3) , installation, 4) Good, installation, check after the bearing ( 5) , supply lubricant before the installation, open the TIMKEN bearing packing. General grease lubrication, cleaning, not directly fill grease. Lubricating oil, ordinary also don't have to be clean, but, instrument using or high speed bearings, etc. , to be washed with clean oil, remove rust inhibitor) on the bearing. Remove the rust inhibitor of bearing, easy to rust, so can not be placed in the air. To have the bearing grease sealed, can not directly use cleaning. TIMKEN bearing installation method, because the bearing structure, cooperate, conditions vary, in general, as more as the axis of rotation, so the inner circle need interference fit. Cylindrical hole bearing, multi-purpose press pressure into, or multi-purpose hot charging method. Taper hole, installed directly on the taper shaft, or use the socket installation. When installed on the shell, clearance fit more commonly, outer ring have surplus quantity, usually use the pressure into the press and or have shrink fit method of cooling after installation. Use dry ice as coolant, shrink fit installation, the moisture in the air condenses on the surface of bearing. So, need a good rust prevention measures. If you look closely at orbit, will know that only bear radial load, bear the axial load of big, inherit the torque load, or extreme rigid in bearing box is not equal. Can check if the bearing with accidents such as whether the load and the installation error of kingdoms, TIMKEN bearing damage and be investigated as a reason for clues.
