Description

Tapered roller bearing outer ring extrusion tool

Technical Field

The utility model belongs to bearing inner race extrusion instrument field, concretely relates to tapered roller bearing inner race extrusion instrument.

Background

The tapered roller bearing belongs to a separated bearing, and the inner ring and the outer ring of the bearing are both provided with tapered roller paths. The bearing is divided into single-row, double-row and four-row tapered roller bearings according to the number of rows of rollers. The single-row tapered roller bearing can bear radial load and single-direction axial load. When the bearing bears radial load, an axial component is generated, so that another bearing capable of bearing opposite axial force is needed for balancing, and the capability of the single-row tapered roller bearing for bearing the axial load depends on the contact angle, namely the angle of the outer ring raceway, wherein the larger the angle is, the larger the axial load capability is. The most used of the tapered roller bearings is the single row tapered roller bearing. In the front wheel hub of the car, a small-sized double-row tapered roller bearing is used. Four-row tapered roller bearings are used in heavy machinery such as large cold and hot rolling mills.

The existing conical roller bearing outer ring extrusion tool is uneven in bearing outer ring stress, large in impact force, not suitable for replacing a mark gasket and poor in using effect, and therefore the conical roller bearing outer ring extrusion tool is provided.
