Abstract
The utility model discloses a component for positioning of a bearing, which is convenient to mount and reliable in positioning. The utility model adopts the technical scheme that the component for positioning of the bearing comprises a pre-tightened bolt, a stepped shaft, a left check ring, an oscillating bearing, a right check ring and a structural body which are assembled sequentially from left to right, wherein a small amount of interference fit is formed between the right check ring and the structural body.
Description
Technical field
The utility model relates to a kind of bearing unit, relates in particular to the assembly that bearing is carried out to axially locating.
Background technique
At the heavy engineering machinery industry, the heavy-duty bearing at mill type cylinder two ends limits because of assembly space, and often there is larger gap in its axially locating.
The model utility content
The purpose of this utility model is to address the above problem, and a kind of bearing positioning component is provided, and it is easy for installation, and location is reliable.
The technical solution of the utility model is: the utility model has disclosed a kind of bearing positioning component, comprise the pretension bolt, multidiameter shaft, left side back-up ring, joint shaft bearing, right side back-up ring, the structure that from left to right assemble successively, wherein between right side back-up ring and structure, have a small amount of interference fit.
According to an embodiment of bearing positioning component of the present utility model, the left side back-up ring is positioned at the chamfering position at the ladder place of multidiameter shaft.
According to an embodiment of bearing positioning component of the present utility model, reserved a small amount of gap between multidiameter shaft and structure.
The utility model contrast prior art has following beneficial effect: scheme of the present utility model is to adopt the shaft shoulder of assembling type baffle ring and multidiameter shaft to carry out the axially locating bearing, compared to prior art, following beneficial effect is arranged: 1) the back-up ring assembling is simple; 2) can control more accurately the axially locating of bearing, even the pretightening force of bolt can be passed to bearing inner race, effectively prevent the bearing axial float.
The accompanying drawing explanation
Fig. 1 shows the structure of the preferred embodiment of bearing positioning component of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 shows the structure of the preferred embodiment of bearing positioning component of the present utility model.Refer to Fig. 1, the bearing positioning component of the present embodiment comprises from left to right pretension bolt 1, multidiameter shaft 2, left side back-up ring 3, joint shaft bearing 4, right side back-up ring 5, the structure 6 of assembling successively, wherein between right side back-up ring 5 and structure 6, has a small amount of interference fit.Left side back-up ring 3 is positioned at the chamfering position at the ladder place of multidiameter shaft 2, can eliminate like this impact that multidiameter shaft 2 ladder place chamferings are brought machining, assembling.Reserved a small amount of gap between multidiameter shaft 2 and structure 6, treat bolt tightening after gap will eliminate.
Adopt the bearing positioning component of said structure can be so that the back-up ring assembling is simple, and can control more accurately the axially locating of bearing, even the pretightening force of bolt can be passed to bearing inner race, effectively prevent the bearing axial float.
Above-described embodiment is to provide to those of ordinary skills and realizes and use of the present utility model; those of ordinary skills can be in the situation that do not break away from invention thought of the present utility model; above-described embodiment is made to various modifications or variation; thereby protection domain of the present utility model do not limit by above-described embodiment, and it should be the maximum magnitude that meets the inventive features that claims mention.
