Cone roller bearing mounting structure

Abstract

The invention discloses an installation structure of a conical roller bearing, comprising a base body plate which is provided with a shaft hole, a shaft which is passed through the shaft hole, a bearing base which is fixedly arranged on the base body plate, and the conical roller bearing which is arranged in the bearing base. The inner ring of the conical roller bearing is fixedly installed on the shaft, and the small end face of the inner ring is rightly relative to the bearing base. The outer ring of the conical roller bearing and the bearing base are assembled in method of transition fit or interference fit, a top cover is arranged in the bearing base, a threaded hole is opened on the end face of the bearing base, a first screw is engaged with the inner portion of the threaded hole andis pressed on the top cover to tightly press the top cover with the large end face of the outer ring of the conical roller bearing, and the bearing clearance can be regulated through rotating the first screw, which can avoid the problem that the clearance between the inner ring and the outer ring of the bearing is over larger or smaller.

Description

technical field [0001] The invention relates to a mounting structure of a tapered roller bearing. Background technique [0002] In the prior art, the tapered roller bearing is installed in the bearing seat, and the distance between the outer end surface of the bearing and the end surface of the bearing seat is generally measured, and then the distance is used as the depth dimension of the bearing seat. The seat is tight, which can keep the minimum gap between the inner ring and the outer ring of the bearing all the time, so as to ensure the normal operation of the bearing. However, due to large errors in the measurement process, especially the size difference of the bearing under lubricated and non-lubricated conditions, the above-mentioned solution is likely to cause the clearance of the bearing to be too large or too small. If the bearing clearance is too large, the shaft will easily jump and vibrate during operation; if the bearing clearance is too small, the shaft will ...

Problems solved by technology

However, due to large errors in the measurement process, especially the size difference of the bearing under lubricated and non-lubricated conditions, the above-mentioned scheme is likely to cause the clearance of the bearing to be too large or too small

If the bearing clearance is too large, the shaft will easily jump and vibrate during operation; if the bearing clearance is too small, the shaft will easily be stuck after thermal expansion, resulting in equipment damage
