Abstract

The utility model relates to an anti-deviation bearing, which comprises an outer ring, an inner ring and a roller, wherein the roller is arranged in a chute between the outer ring and the inner ring, and the width of the inner ring is more than three times larger than that of the outer ring. The anti-deviation bearing can be used for effectively fixing various mechanical rotary shafts, and compared with an ordinary bearing, the anti-deviation bearing can make the rotary shaft and the outer ring of the bearing keep excellent concentricity.

Description

Anti-deviation bearing

Affiliated technical field

The utility model relates to the mechanical fitting field, especially, is a kind of bearing.

Background technique

At mechanical field, bearing is various driven off by shaft basic accessories, mainly is divided into sliding bearing and rolling bearing.And present bearing includes inner ring, outer ring, rolling bearing also comprises the roller structure between the Internal and external cycle, wherein, inner ring and rotating shaft are fixed, and outer ring and pedestal are fixed, because the constraint that the outer ring must be subjected to being fixed in the cartridge housing on the pedestal, therefore, its width is unsuitable excessive, and inner ring is pressed close to rotating shaft, so its width institute is restricted less.

For present bearing, the width of its inner ring and outer ring is basic identical, shown in Figure of description 1, in a rolling bearing, comprise outer ring 1, inner ring 2, ball 3, wherein outer ring 1 width equals inner ring 2 width, the width that is inner ring 2 and outer ring 1 is all smaller, and when fixed rotating shaft, inner ring 2 is less with the coating surface of rotating shaft, then inner ring 2 is less with the coaxality of rotating shaft, and the coaxality of inner ring 2 and outer ring 1 also is subjected to the restriction of technology, therefore, and in the rotating shaft rotation process, coaxiality deviation will occur, thereby accelerate the wearing and tearing of machinery.

Summary of the invention

At the problems referred to above, the purpose of this utility model is to provide a kind of anti-deviation bearing, and this anti-deviation bearing not only can carry out effectively fixing to all kinds of mechanical rotating shafts, and with respect to plain bearing, can make rotating shaft and bearing outer ring keep fabulous coaxality.

The technological scheme that its technical problem that solves the utility model adopts is: this anti-deviation bearing comprises outer ring, inner ring, roller, and described roller is located in the chute between described outer ring and the inner ring, and the width of described inner ring is at more than three times of described outer ring.

As preferably, described roller is a steel ball.

As preferably, described inner ring is symmetrical arranged about described outer ring.

The beneficial effects of the utility model are: for plain bearing, have bigger surface of contact between the inner ring of this anti-deviation bearing and the rotating shaft, thereby make rotating shaft and inner ring keep highly coaxial, thereby make rotating shaft and bearing outer ring keep coaxality preferably.

Description of drawings

Fig. 1 is the structural representation of common rolling bearing.

Fig. 2 is the structural representation of this anti-deviation bearing.

Embodiment

In embodiment illustrated in fig. 2, this anti-deviation bearing comprises outer ring 11, inner ring 22, roller 33, and described roller 33 is located in the chute between described outer ring 11 and the inner ring 22, and the width of described inner ring 22 is at more than three times of described outer ring 11.

Above-mentioned anti-deviation bearing, described roller 33 is a steel ball.

Above-mentioned anti-deviation bearing, described inner ring 22 is symmetrical arranged about described outer ring 11.

For plain bearing, have bigger surface of contact between the inner ring 22 of above-mentioned anti-deviation bearing and the rotating shaft, thereby make rotating shaft and inner ring 22 keep highly coaxial, thereby make rotating shaft and bearing outer ring 11 keep coaxality preferably.
