Description

Technical Field

[0001] The utility model relates to the technical field of tapered roller bearing processing, in particular to a device for grinding the outer side 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 bear radial loads and unidirectional axial loads. When the bearing bears radial loads, an axial force component will be generated, so another bearing that can withstand the axial force in the opposite direction is required to balance it. Existing bearings need to be polished before use;
