CN203532538U - Bearing with tight installation - Google Patents

Abstract

The utility model discloses a bearing with tight installation. The bearing comprises an inner ring, a steel ball assembly and an outer ring, wherein the steel ball assembly is arranged between the inner ring and the outer ring; a plurality of reinforcing ribs are uniformly arranged inside the inner ring and outside the outer ring; the reinforcing ribs are 0.01mm-0.1mm high; three or more reinforcing ribs are uniformly distributed; the reinforcing ribs on the inner ring are the same in height; the reinforcing ribs on the outer ring are the same in height. The bearing with the tight installation has the beneficial effects that the bearing is simple in structure; the reinforcing ribs are respectively arranged inside the inner ring and outside the outer ring of the bearing, so that the connections between the bearing and a bearing base, and between the bearing and a rotation shaft are tight, and no loosing phenomenon exists; furthermore, the requirement on the machining precision of the rotation shaft and the bearing base is reduced, the machining efficiency of the rotation shaft and the bearing base can be improved, the cost is reduced, and the practicability is high.

Description

A kind of installation is bearing closely

Technical field

The utility model belongs to field of bearings, relates in particular to a kind of installation bearing closely.

Background technique

It is all to adopt interference fit that existing bearing is installed; but when installing, often there will be the situation that bearing saddle bore is slightly large or rotating shaft diameter is less than normal; making like this bearing to skid even comes off; affect the normal work of bearing; encountering the solution that this situation is traditional is that bearing support or rotating shaft are directly scrapped to processing, has caused a large amount of wastes of material.

Model utility content

The purpose of this utility model is the deficiency for above-mentioned technology, and a kind of bearing that increases bearing installation tightness that has is provided.

To achieve these goals, the utility model is that the technological scheme that its technical problem of solution is taked is:

Installation is a bearing closely, comprises interior ring, steel ball assembly and outer shroud, and steel ball assembly is located between interior ring and outer shroud, in described interior ring inside and outer shroud outside, is equipped with many stiffening ribs, and the height of described stiffening rib is 0.01mm-0.1mm.

Further, described stiffening rib is more than three or three, and is uniformly distributed.

Further, each stiffening rib on described interior ring is contour, and each stiffening rib on outer shroud is contour.

The beneficial effects of the utility model are: the utility model interior ring inside and outer shroud outside at bearing simple in structure all arranges stiffening rib, make to be connected between bearing and bearing support and rotating shaft tightr, there will not be relaxation phenomenon, and the requirement on machining accuracy of rotating shaft and bearing support is reduced, improve the work efficiency of rotating shaft and bearing support, reduce costs, practical.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

A kind of installation is as shown in Figure 1 bearing closely, comprise interior ring 1, steel ball assembly 2 and outer shroud 3, steel ball assembly 2 is located between interior ring 1 and outer shroud 2, it should be noted that, in described interior ring 1 inside and outer shroud 2 outsides, be equipped with many stiffening ribs 4, the height of described stiffening rib 4 is 0.01mm-0.1mm.

Further it should be noted that described stiffening rib 4 is more than three or three, and be uniformly distributed.

Further it should be noted that each stiffening rib 4 on described interior ring 1 is contour, each stiffening rib 4 on outer shroud 2 is contour.

The utility model interior ring inside and outer shroud outside at bearing simple in structure all arranges stiffening rib, make to be connected between bearing and bearing support and rotating shaft tightr, there will not be relaxation phenomenon, and the requirement on machining accuracy of rotating shaft and bearing support is reduced, improve the work efficiency of rotating shaft and bearing support, reduce costs, practical.

More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope, those ordinary skill in the art's simple change and replacement are all within protection domain of the present utility model.

Claims (3)

1. one kind bearing is closely installed, comprise interior ring, steel ball assembly and outer shroud, steel ball assembly is located between interior ring and outer shroud, it is characterized in that: in described interior ring inside and outer shroud outside, be equipped with many stiffening ribs, the height of described stiffening rib is 0.01mm-0.1mm.

2. a kind of installation according to claim 1 bearing closely, is characterized in that: described stiffening rib is more than three or three, and is uniformly distributed.
