Abstract

The utility model relates to a tapered roller bearing with an aligning ring, comprising an outer ring (2), an inner ring (3) and tapered rollers (5). The utility model is characterized in that the aligning ring (1) is sleeved on and matched with the outside of the outer ring (2) and can rotate relatively to the outer ring (2). The utility model integrates the advantages of both aligning roller bearing and the tapered roller bearing, enables automatic bearing aligning and the pure rotation of a rotating body, effectively reduces the bearing installation error and the deformation caused by big change of the bearing working temperature, reduces the power loss caused by the sliding friction and increases the service life of the bearing.

Description

The tapered roller bearing that has self-aligning ring

Technical field

The utility model relates to a kind of tapered roller bearing that has self-aligning ring.

Background technique

Tapered roller bearing commonly used, mainly bear based on radially radially, axial connected load, and bearing capacity is big.Usually tapered roller bearing is the separable type structure, outer ring, inner ring assembly can be installed respectively, and double-row conical bearing, adjust bearing clearance or pretightening force by the spacer ring between inner ring or outer ring, outer ring raceway bus, roller bus, inner ring raceway bus elongation line meet at a bit, can realize pure rolling in theory, reduce the power loss that friction causes.And selfaligning roller bearing bearing capacity height, resistance to shock is good, and can compensate because the concentricity that the distortion of installation and axle causes.

Existing tapered roller bearing does not possess the aligning function usually, so can't compensate because the concentricity that the distortion of installation and axle causes causes wearing and tearing easily.

The model utility content

The purpose of this utility model provides a kind of easy installation and removal, can compensate because the tapered roller bearing that has self-aligning ring of the concentricity that the distortion of installation and axle causes.

The technical solution adopted in the utility model is:

A kind of tapered roller bearing that has self-aligning ring comprises outer ring, inner ring and tapered roller, and its specialization is, thereby also is with a self-aligning ring that matches and can rotate to it with this outer ring in the outside, described outer ring.

Wherein said outer ring outer surface and self-aligning ring internal surface are arcuate surface.

Wherein said outer ring outer surface and self-aligning ring internal surface are spherical surface.

Retainer wherein also is installed.

Cone spacer wherein also is installed.

The utility model combines aligning roller and the structural advantage of tapered roller bearing, a kind of bearing self-aligning and rolling element pure rolling have been solved, solved the distortion that Bearing Installation error and bearing working temperature variation cause more greatly effectively, reduced power, improved bearing life because of the sliding friction loss.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model background technique;

Accompanying drawing 2 is a structural representation of the present utility model.

Embodiment

Come the utility model is described in further detail below in conjunction with accompanying drawing:

Be illustrated in figure 1 as the structural representation of existing conventional tapered roller bearing, the tapered roller bearing of this kind structure does not possess the function of self-aligning in use, easily because alignment error and bearing deformation cause wearing and tearing.

As shown in Figure 2, also be with a self-aligning ring 1 that matches with this outer ring 2 in the outside of bearing outer ring 2, thereby outer ring 2 and self-aligning ring 1 can be relatively rotated, specifically be that outer ring 2 outer surfaces and self-aligning ring 1 internal surface are spherical surface, and can control and relatively rotate the required frictional force that overcomes by adjusting the gap between outer ring 2 and the self-aligning ring 1 and the coefficient of sliding friction.

Compare with existing conventional tapered roller bearing, the utility model in the outer ring 2 outside suits one self-aligning ring 1, because can be within the specific limits between outer ring 2 and the self-aligning ring 1, relatively rotate under the certain condition, thereby realized bearing self-aligning in use.

Clearly, in the utility model the outer ring 2 of indication and self-aligning ring 1 can relatively rotate be meant outer ring 2 can relative self-aligning ring 1 left or turn right moving (with reference to direction shown in the figure 2), perhaps self-aligning ring 1 relatively outer ring 2 left or turn right moving (with reference to direction shown in the figure 2), and outer ring 2 relatively self-aligning ring 1 rotate as circumferencial direction and the technical problems to be solved in the utility model has nothing to do.
