Method for adjusting clearance of four-single-raceway outer ring four-row tapered roller bearing

Abstract

The invention relates to a method for adjusting a clearance of a four-single-raceway outer ring four-row tapered roller bearing. The method comprises the following steps: step I, preparing before the adjustment, and marking on end surfaces of ferrules and outer-diameter surfaces of all space rings by utilizing an electric pen according to letters shown by a clearance adjustment specification pattern; step II, locating an inner ring positioning end surface which is assembled on the lower part on a horizontal position before the measurement; step III, adjusting the axial clearance of the bearing by adopting a way of arranging outer space rings, and determining the width C1C1 of a first outer space ring and the width of second outer space rings B1B1 and D1D1 according to the letter marker shown in the step I. When the width of the first outer space ring is determined, the bearing only needs to be overturned for one time, when the width of the second outer spacer ring is determined, the bearing does not need to be overturned, and the width of the second outer spacer ring can be directly measured, so that the measurement error can be reduced, the accuracy in measurement can be improved, great convenience in operation can be realized, and the measurement can be carried out only by utilizing six cushion blocks under the situation without platforms.

Description

technical field [0001] The invention relates to a bearing clearance adjustment method in the bearing manufacturing technology, in particular to a four-row tapered roller bearing clearance adjustment method with four single-raceway outer rings, one double-raceway inner ring and two single-raceway inner rings. Background technique [0002] The traditional four-row tapered roller bearing clearance measurement method requires the bearing to be turned over at least 4 times. The more the number of turns, the greater the measurement error and poor operability; this measurement method requires a larger platform , when the user questions the bearing clearance and requires staff to check the clearance on site, generally there is no platform on site, so on-site measurement cannot be carried out. Therefore, the scope of application of this method is small, and the measurement has certain limitations. ; At the same time, there are certain difficulties in the manufacture and verification ...
