Abstract
The utility model provides a kind of needle bearing, including outer ring, inner ring and the multiple needle rollers being arranged between the outer ring and inner ring, the width of the outer ring is more than the width of the inner ring, the side of outer ring is provided with plastics baffle ring, the other side of the outer ring is provided with ring-shaped groove, is provided on the inner ring and the matched annular protrusion of the ring-shaped groove.The utility model has the advantages that：Due to the equal rib of inside and outside ball, needle roller is in closed state, and product is integrated, and will not be fallen apart.
Description
Technical field
The utility model belongs to technical field of bearings, and in particular to a kind of needle bearing.
Background technology
Currently, needle bearing has generally comprised outer ring, inner ring, needle roller and retainer, needle roller is installed on retainer, and right
It should be between outer ring and inner ring, since existing retainer is both ends all structures with rib, so that needle roller
Axial length is relatively small, so that the bearing capacity of bearing is also relatively small.
Utility model content
The technical problems to be solved in the utility model is how to provide a kind of needle bearing, it is intended to solve above-mentioned technology and ask
Topic.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of needle bearing, including outer ring, inner ring and the multiple needle rollers being arranged between the outer ring and inner ring, it is described
The width of outer ring is more than the width of the inner ring, and the side of outer ring is provided with plastics baffle ring, and the other side of the outer ring is provided with
Ring-shaped groove is provided with and the matched annular protrusion of the ring-shaped groove on the inner ring.
Further, it is provided with annular groove on the inner ring.
Further, the needle roller is arranged in the chamber that annular groove and outer ring inner wall are formed.
Further, it is provided with annular groove on the outer ring, solid lubricating material is provided in the annular groove.
Further, the cross section undulate of the annular groove.
Further, the solid lubricating material is graphite.
Compared with prior art, the utility model has the advantages that：Due to the equal rib of inside and outside ball, needle roller is in
Closed state, product are integrated, and will not be fallen apart.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of needle bearing of the utility model；
Wherein：
1, outer ring；2, inner ring；3, needle roller；4, plastics baffle ring；5, solid lubricating material；11, ring-shaped groove；12, annular groove；
21, annular protrusion；22, annular groove.
Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
As shown in Figure 1, the utility model provides a kind of needle bearing, including outer ring 1, inner ring 2 and setting described
Multiple needle rollers 3 between outer ring 1 and inner ring 2, the width of the outer ring 1 are more than the width of the inner ring 2, and the side of outer ring 1 is set
It is equipped with plastics baffle ring 4, the other side of the outer ring 1 is provided with ring-shaped groove 11, is provided on the inner ring 2 and the annular ditch
11 matched annular protrusion 21 of slot.
Annular groove 22 is provided on the inner ring 2, the setting of the needle roller 3 is formed in annular groove 22 and 1 inner wall of outer ring
Chamber in.
It is provided with annular groove 12 on the outer ring 1, solid lubricating material 5 is provided in the annular groove 12.The annular groove 12
Cross section undulate.The solid lubricating material 5 be graphite so that needle roller rotation when can self-lubricating, greatly reduce
The friction of ball and inner ring and outer ring prolongs the service life so that needle roller is more smooth when rotating.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.
