CN201437819U - Novel cylindrical roller bearing - Google Patents

Abstract

The utility model discloses a novel cylindrical roller bearing with high running accuracy, large load bearing and long service life, which is suitable for stretching and can combine a die and a common bearing into one and comprises an outer ring provided with double ribs, an inner ring without rib, a retainer and a group of cylindrical rollers. The novel cylindrical roller bearing is characterized in that the middle part of the outer surface of the outer ring is processed to be a hemispheric concave slot to replace the generally-used die slot, so that the bearing and the die are prevented from being installed again, thereby eliminating errors, improving the accuracy and prolonging the service life.

Description

Novel roller bearing

Technical field

The utility model relates to component of machine, particularly a kind of novel roller bearing.

Background technique

At present the bearing means of cable stretching usefulness is that plain bearing adds mould and realizes that its precision is lower, and bearing capacity is little, and working life is short.

The model utility content

In order to overcome the deficiencies in the prior art, the utility model provides a kind of being applicable to stretch and the running accuracy height, mould and plain bearing are united two into one, the novel roller bearing that carrying is big, the life-span is long, the outer ring that comprises the two ribs of band, the inner ring of no rib, a retainer and one group of cylindrical roller, its structural feature is that the outer surface middle part of outer ring is processed as the hemisphere face concave groove, replace the general mold slots of using, thereby reduced the secondary installing of bearing and mould, and reduced error, improved precision and working life.

Owing to adopted above technological scheme, the utlity model has following beneficial effect: existing roller bearing is combined with the mould type groove improved running accuracy, bearing capacity, the life-span is long and easy to use.

Description of drawings

Fig. 1 is a structural representation of the present utility model

In the drawings: 1-outer ring, 2-inner ring, 3-solid cage, one group of cylindrical roller of 4-

Embodiment

As shown in Figure 1, a kind of novel roller bearing that the utility model provides, comprise outer ring 1, inner ring 2, solid cage 3 and one group of cylindrical roller 4, its structural feature is that the outer surface middle part of outer ring is processed as the hemisphere face concave groove, replace the general mold slots of using, thereby reduced the secondary installing of bearing and mould, and reduced error, improved precision and working life.

It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.

Claims (1)

1. a novel roller bearing comprises outer ring, inner ring, solid cage and one group of cylindrical roller, it is characterized in that: the outer surface middle part of outer ring is processed as the hemisphere face concave groove.
