Technical Field

[0001] The utility model relates to the technical field of tapered roller bearing fixtures, in particular to a tooling fixture for the inner ring of a tapered roller bearing. Background Art

[0002] Tapered roller bearings are separable bearings, and 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. The structure of the tapered roller bearing itself is divided into four parts: outer ring, cage, tapered roller and inner ring, and a mounting groove is provided in the middle of the outer side surface of the inner ring structure.
