SKF thrust ball bearing installation method and matters needing attention

SKF thrust ball bearing and shaft with transition fit, seat and the bearing holes with the general for the clearance fit, the center axis of the two-way SKF thrust ball bearing ring should be fixed on the shaft, in order to prevent the relative to the axis of rotation. SKF thrust ball bearing installation method, usually is the situation of the axis of rotation, so the inner ring cooperate for win cooperate with shaft, with the bearing outer ring and bearing chamber for clearance fit. Installing a SKF thrust ball bearing, shaft washer shall be checked and verticality of shaft centerline. Method is to fix the dial gauge box shell end face, make the table touch the top of the head of the ring raceway on bearing axle bearing, and observe the dial gauge pointer, if the pointer deflection, axial circle and not vertical shaft centerline. Box shell hole deep, also can use extended dial gauge head test. SKF thrust ball bearing is installed correctly, the seat can automatically adapt to roller rolling, to ensure that the rolling elements located at the top and bottom ring raceway. If installed backwards, bearing not only don't work properly, and the matching surface will badly worn. Due to axial ring and seat and the difference is not obvious, the assembly should be extra careful, do not make a mistake. In addition, the seat of SKF thrust ball bearing and the bearing hole there should also be between 0. 2 - 0. 5 mm clearance to compensate parts processing, installation error caused by inaccurate, when the bearing ring during operation center offset, the clearance can be adjusted to ensure the automatic, the avoidance of friction, make its normal operation. Otherwise, will cause bearing severe damage. Plane SKF thrust ball bearing in the assembly mainly bear axial load, its wide application. Although SKF thrust ball bearing installation operation is simple, but it is still common errors occur when maintenance, tight ring of the bearing and loose ring installation position is not correct, the results lose bearing, shaft neck quickly wear. Tight ring of inner ring and shaft neck as transition fit, when the shaft rotates driven tight ring, and end face friction with stationary parts, under the axial force ( 外汇) , there will be friction torque is greater than the inner diameter with resistance moment, locking ring and shaft mating surface forced rotation, intensifying journal wear. Therefore, SKF thrust ball bearing when installation should pay attention to the following points. ( 1) Distinguish tight ring of bearing and loose ring ( According to the bearing inner diameter size, aperture is 0. 1 to 0. 5毫米) 。 ( 2) The static distinguish institutions. ( The parts movement does not occur, is mainly refers to assembly) 。 ( 3) In any case, bearing rings should always be on stationary on the face of.
