The adjustment of TIMKEN bearings

Timken bearing adjustment, unlike other circular aperture to the bearings, single row angular contact ball timken bearings and tapered roller bearing internal clearance, only in a bearing for another bearing adjustment can be established. Usually these bearings pairing is back to back or face to face, one of the bearing ring for axial displacement, until the selected clearance or preload is reached. The choice of clearance or preload, depends on the layout of bearing performance and the requirement of operation condition. Details about the bearing preload, see 'bearing preload control' section. Therefore, the following Suggestions only involves the angular contact ball bearings and tapered roller bearings bearing internal clearance adjustment layout. When installation should achieve the appropriate clearance value, according to the working load and temperature of bearing condition to determine. According to the size and layout of the bearing, shaft and bearing box manufacturing materials, and the distance between two bearings, the initial clearance when installation in the actual operation may be smaller or bigger. Inside and outside the circle, for example, the temperature difference of thermal expansion will cause the operation of the middle gap narrowed, initial clearance must be quite big, so to avoid timken bearing deformation and its adverse consequences. Due to angular contact ball bearings and tapered roller bearing radial and axial internal clearance there is a definite relationship between, so, you only need to specify a numeric value. Usually specify the axial internal clearance. Can then be generated by the following methods from zero clearance status of the specified value: loosen or tighten the nut on the shaft rod or body part of screw shaft hole, or between a bearing ring and its bearing insert calibration of gasket or gasket. Used to adjust the clearance with clearance measurement set practical method, depending on the amount of the number of bearings to install. For example, there is a kind of method is to use in a dial indicator on the wheel hub, check the wheel hub bearing set the layout of the axial clearance. It is important that the adjustment of tapered roller timken bearings and measure the clearance, rotating shaft or the bearing box to each in a different direction for weeks, to ensure that the ball end with the guide flange on the inner ring with the proper contact. If improperly contact measurement result is not accurate, can not achieve the desired adjustment purpose. 【 The bearing network]
