Abstract
The invention relates to a thrust spherical roller bearing used in a crusher. The bearing comprises an outer ring (1) and an inner ring (2), the outer ring (1) is sheathed outside the inner ring (2); and the bearing is characterized by further comprising rolling elements (3) and a retainer (4), the rolling elements (3) are filled in a slit formed by the inner ring (2) and the outer ring (1), and separated from the inner ring (2) and the outer ring (1) by the retainer (4). The thrust spherical roller bearing has the beneficial effects of replacing a sliding bearing at a conical head broken part of the crusher with the thrust spherical roller bearing, reducing the bearing friction, accelerating the rotation speed of the bearing, and improving the operating efficiency of the crusher.
Description
Technical field
The present invention and mechanical industry technical field relate in particular to 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.
Summary of the invention
The purpose of this invention is to provide a kind of thrust force aligning roller bearing for cracking machine, reduce pivot friction, improve the bearing rotating speed, improve the working efficiency of disintegrator.
In order to achieve the above object, technological scheme of the present invention is as follows:
Thrust force aligning roller bearing for cracking machine comprises outer ring, inner ring, and the outer ring is enclosed within outside the inner ring, 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.Relative movement between outer ring and the inner ring is a rolling motion, and inner ring, rolling element and retainer are combined into indissociable assembly and realize rolling in the outer ring.
The invention has the beneficial effects as follows: 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 thrust force aligning roller bearing for cracking machine of the present invention.
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 present invention is done description in further detail:
As shown in Figure 1, the present invention includes outer ring 1, inner ring 2, rolling element 3 and retainer 4, outer ring 1 is enclosed within outside the inner ring 2, and rolling element 3 is packed in the slit of inner ring 2 and outer ring 1, isolates by retainer 4 and inner ring 2, outer ring 1.
The present invention changes into self-aligning thrust roller bearing with the sliding bearing of the broken head part of disintegrator circular cone, 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)
1, thrust force aligning roller bearing for cracking machine, comprise outer ring (1), inner ring (2), rolling element (3) and retainer (4), it is characterized in that, rolling element (3) is packed in the slit of inner ring (2) and outer ring (1), isolate by retainer (4) and inner ring (2), outer ring (1), relative movement between outer ring (1) and the inner ring (2) is a rolling motion, and inner ring (2), rolling element (3) and retainer (4) are combined into indissociable assembly and outer ring (1) realizes rolling.
