Description

Technical Field

[0001] The utility model belongs to the technical field of bearings, and more specifically, particularly relates to a locking structure of a tapered roller bearing. Background Art

[0002] Tapered roller bearings are separable bearings. Both the inner and outer rings of the bearings have tapered raceways. This type of bearing is divided into single-row, double-row and four-row tapered roller bearings according to the number of rows of rollers installed. Single-row tapered roller bearings can withstand radial loads and unidirectional axial loads. When the bearing is subjected to radial loads, an axial force component will be generated, so another bearing that can withstand the axial force in the opposite direction is needed to balance it.

[0003] Based on the above, in the existing single-row paired tapered roller bearing structure, the connection between the inner shaft and the outer shaft is too loose, which reduces the applicability of the bearing. Utility Model Content

The utility model can not only solve the problem of too large gap between the inner shaft and the outer shaft, but also improve the applicability of the bearing.

At the same time, the annular convex ring is fitted and rotatably installed in the annular groove holes.

Locking screw holes are provided in the annular slots of the first outer shaft and the second outer shaft, and the locking screw hole array is provided with six groups. At the same time, locking bolts are fixedly installed inside the locking screw holes.
