Abstract
The invention discloses a needle roller bearing with non-driven retainers and an opening on an outer ring, aiming to provide a needle roller bearing with non-driven retainers and an opening on an outer ring with simple structure and convenient processing and mounting. The needle roller bearing comprises the outer ring, wherein the outer ring is internally provided with circumferentially distributed needle rollers; the needle rollers are mutually isolated by the retainers; and one end face of the outer ring is provided with a flange. The needle roller bearing is characterized in that the other end face of the outer ring is an opening; and the width A of the retainers is larger than the width B of the inner shield of the outer ring. In the invention, even if the needle rollers rotate, the retainers cannot be driven; in addition, the flange is only on one end face of the outer ring, while the flange of the other end face does not need to be made, thus hemming process which is more complicated and has difficultly guaranteed quality is omitted, and consumed materials are also less than before.
Description
Technical field
The present invention relates to needle bearing, relate in particular to the needle bearing of the not driven and outer ring opening of a kind of retainer.
Background technique
Needle bearing is a kind of part commonly used in the mechanical rotation.Traditional needle bearing is normally loaded onto needle roller and retainer in the outer ring that punching press pull and stretch or Vehicle Processing are made, and then an end crimping forms the two ends rib, with moving axially of restriction needle roller and retainer.But can not fundamentally solve moving axially of needle roller and retainer like this, can make on the contrary retainer with needle roller driven in produce friction with rib, cause bearing noise excessive, the life-span descends.
The content of invention
The present invention has overcome the shortcoming that exists in the prior art, provides a kind of simple in structure, and processing, retainer easy for installation is not driven and the needle bearing of outer ring opening.
In order to solve the problems of the technologies described above, the present invention is achieved by the following scheme: it includes the outer ring, the needle roller of circumferential arrangement is installed in the outer ring, needle roller be held the frame space from, an end face in the outer ring is provided with rib, the other end that it is characterized in that the outer ring is an opening, and the width A of retainer is greater than the width B of working as in the outer ring.Described retainer is made of plastics, and described plastics are Reinforced Nylon.The circumferential groove of system row is shaped on the positioning ring that matches with groove on the retainer in the end face outer ring of opening.
The needle bearing of the not driven and outer ring opening of the retainer of making according to such scheme, though needle roller and retainer are not axially being located with respect to the outer ring, but, the back retainer exceeds outer ring open end certain size because being installed, in actual use, the needle bearing end face of the overwhelming majority is to be blocked and compressed by axial part or packing ring, so retainer is axially compacted under the effect of external force, even the needle roller rotation can not take place driven yet.Present in addition rib only at an end face of outer ring, needn't make by the rib of other end, can save " crimping " operation together that technology more complicated, quality are difficult for guaranteeing like this, with material also than original saving.
Description of drawings
Fig. 1 is the needle bearing plan view of the not driven and outer ring opening of retainer;
Fig. 2 is that retainer needle bearing not driven and the outer ring opening assembles schematic representation;
Fig. 3 is the needle bearing stereogram of the not driven and outer ring opening of retainer.
Among the figure: 1, outer ring; 2, needle roller; 3, retainer; 4, rib; 5, opening; 6, groove; 7, positioning ring.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 to Fig. 3 is the needle bearing structural representation of the not driven and outer ring opening of retainer.It includes outer ring 1 as seen from the figure, the needle roller 2 of circumferential arrangement is installed in outer ring 1, needle roller 2 be held frame 3 spaces from, 1 end face is provided with rib 4 in the outer ring, and the other end of outer ring 1 is an opening 5, and the width A of retainer 3 is greater than the width B of working as in the outer ring 1.Described retainer 3 is made of plastics, and described plastics are Reinforced Nylon.In the end face outer ring 1 of opening 5, be shaped on circumferential groove 6, be shaped on the positioning ring 7 that matches with groove 6 on the retainer 3.
After use installing, retainer 3 exceeds the certain size in outer ring 1, and the distance C (being B-A) that exceeds according to the size of needle bearing is 0.1～0.5mm usually.
Claims (4)
1. the needle bearing of the not driven and outer ring opening of a retainer, include the outer ring, the needle roller of circumferential arrangement is installed in the outer ring, needle roller be held the frame space from, an end face in the outer ring is provided with rib, the other end that it is characterized in that the outer ring is an opening, and the width A of retainer is greater than the width B of working as in the outer ring.
2. the needle bearing of the not driven and outer ring opening of retainer according to claim 1 is characterized in that described retainer is made of plastics.
3. the needle bearing of the not driven and outer ring opening of retainer according to claim 2 is characterized in that described plastics are Reinforced Nylon.
4. according to claim 1 or 2 or 3 described retainers are not driven and the needle bearing of outer ring opening, it is characterized in that in the end face outer ring of opening, being shaped on circumferential groove, be shaped on the positioning ring that matches with groove on the retainer.
