Description

A self-aligning roller bearing with a high load-bearing pillar welded cage

technical field

The utility model belongs to the field of bearing manufacture, in particular to a self-aligning roller bearing with a high load-bearing pillar type welded cage.

Background technique

In the past, spherical roller bearings generally used car-made solid cages. In terms of product design and process, the strength of the cage must be considered, that is, the cage pocket beam width must be greater than a certain value, so it is different from bearings that use pillar welded cages. In contrast, the number of rollers is less, and the rated load is correspondingly much lower.

Utility model content

The purpose of the utility model is to provide a high load-bearing pillar type welded cage spherical roller bearing, the number of rollers of this kind of bearing is increased, and the rated load is increased.

The technical solutions adopted are:

A spherical roller bearing with a high-load-bearing pillar welded cage, which is mainly assembled from an inner ring, an outer ring, two cages, two sets of rolling elements and a pillar, is characterized in that:

The two cages are respectively installed between the inner ring and the outer ring, and the two sets of rolling elements are respectively installed in the raceway formed by the outer ring and the inner ring. The cage is provided with a large washer and a small washer. Pass through the pillar holes of the two groups of rolling elements respectively, the threaded end of the pillar is threadedly connected with the large washer, the small washer at the groove end of the pillar is welded and fixed, and the gap between the pillar hole of the rolling element and the pillar is 4-5mm.

In the design, the number of rolling elements depends on the average clearance of the rolling elements, and the clearance is determined by the gap between the pillar holes of the rolling elements and the pillars. Generally, 4~5mm is selected, and the gap between adjacent rolling elements is generally guaranteed not to be stuck. The rolling elements are enough, so the number of rolling elements in this design is about 10% higher than that of the same car-made solid cage, and the corresponding load is about 5% higher.

Its advantages are:

The utility model overcomes the problem of the strength of the cage, that is, the beam width of the pocket hole of the cage, the number of rollers increases, the rated load increases, the bearing capacity is high, and the centering performance is good, and there is no need to redesign the mold of the cage, which saves costs. The service life of the bearing is improved, while the process is reduced, the manufacturing cost is low, and the rotation flexibility of the bearing is improved.
