Abstract

A thrust self-aligning roller bearing for crusher comprises an outer ring (1) and an inner ring (2), wherein the outer ring (1) is sleeved outside the inner ring (2). The thrust self-aligning roller bearing is characterized by further comprising a rolling body (3) and a retainer (4), and the rolling body (3) is installed in a gap between the inner ring (1) and the outer ring (2), and is separated from the inner ring (1) and the outer ring (2) through the retainer (4). The thrust self-aligning roller bearing has the beneficial effects that a sliding bearing on the conical crushing head part of a crusher is changed into the thrust self-aligning roller bearing, the bearing friction is reduced, the rotating speed of the bearing is increased, and the work efficiency of the crusher is improved.

Description

A kind of thrust force aligning roller bearing for cracking machine

Technical field

The utility model relates to the mechanical industry technical field, relates in particular to a sharp thrust force aligning roller bearing for cracking machine.

Background technique

International economy development at present rapidly, and is more and more to the disintegrator demand both at home and abroad, and also more and more higher to the requirement of disintegrator calculifragous efficiency, existing disintegrator can't satisfy the requirement of efficient a large amount of rubbles, must improve.As shown in Figure 1, the sliding bearing of the existing broken head part of disintegrator circular cone, mainly form by outer ring 1a and inner ring 2a, relative movement between outer ring 1a and the inner ring 2a is to slide, the design bearing of this kind structure makes the bearing rotating speed of the broken head part of disintegrator circular cone can not improve, and calculifragous efficiency is low, therefore, need carry out Transform Type design to this type of sliding bearing.

The model utility content

The purpose of this utility model provides a kind of thrust force aligning roller bearing for cracking machine, reduces pivot friction, improves the bearing rotating speed, improves the working efficiency of disintegrator.

In order to achieve the above object, the technical solution of the utility model is as follows:

A kind of thrust force aligning roller bearing for cracking machine comprises outer ring, inner ring, and the outer ring is enclosed within outside the inner ring, it is characterized in that, also comprises rolling element and retainer, and rolling element is packed in the slit of inner ring and outer ring, isolates by retainer and inner ring, outer ring.

The beneficial effects of the utility model are: the sliding bearing of the broken head part of disintegrator circular cone is changed into self-aligning thrust roller bearing, reduce pivot friction, improve the bearing rotating speed, improve the working efficiency of disintegrator.

Description of drawings

Fig. 1 is the structural representation of existing disintegrator with sliding bearing.

Fig. 2 is the structural representation of the utility model thrust force aligning roller bearing for cracking machine.

Among the figure: 1a, outer ring, 2a, inner ring, 1, the outer ring, 2, inner ring, 3, rolling element, 4, retainer.

Embodiment

Below in conjunction with accompanying drawing the utility model is done description in further detail:

As shown in Figure 1, thrust force aligning roller bearing for cracking machine of the present utility model comprises outer ring 1, inner ring 2, rolling element 3 sharp retainers 4, and outer ring 1 is enclosed within outside the inner ring 2, rolling element 3 is packed in the slit of inner ring 1 and outer ring 2, isolates by retainer 4 and inner ring 1, outer ring 2.

The utility model is that the sliding bearing of the broken head part of disintegrator circular cone is changed into self-aligning thrust roller bearing, between the outer ring 1 of bearing and inner ring 2, increase the retainer 4 of rolling element 3 and separation roller, relative movement between outer ring 1 and the inner ring 2 is changed into rolling motion by slip, improve the bearing rotating speed, and then improve the calculifragous efficiency of disintegrator.Inner ring 2, rolling element 3 and retainer 4 are combined into indissociable assembly, realize the raceway motion as one and outer ring 1.

Claims

1, a kind of thrust force aligning roller bearing for cracking machine, comprise outer ring (1), inner ring (2), outer ring (1) is enclosed within outside the inner ring (2), it is characterized in that, also comprise rolling element (3) and retainer (4), rolling element (3) is packed in the slit of inner ring (1) and outer ring (2), isolates by retainer (4) and inner ring (1), outer ring (2).
