Abstract
The invention provides a semicircular needle roller bearing which is provided with an external ring and a retaining frame, wherein the external ring and the retaining frame are in an ohm shape, and the external ring is arranged on the periphery of the retaining frame, a plurality of needle roller installing holes are formed in the retaining frame, and a plurality of concave grooves are correspondingly arranged on the external ring; the needle roller installing holes in the retaining frame and the concave grooves on the external ring form a space, and needle rollers are arranged in the space; all components above are connected to form a semicircular open type structure; and steps are respectively arranged at two ends of the needle rollers.
Description
Technical field
The present invention relates to bearing, relate in particular to and a kind ofly can convert rotation to translation, minimizing need be done the semicircle needle bearing of surface friction drag between two component of relative translation.Belong to mechanical industry.
Background technique
Existing rolling bearing all is the enclosed construction of circular ring type.Usually comprise from inside to outside: parts such as inner ring, retainer, outer ring and needle roller, wherein, outer ring and inner ring carry out transition fit respectively between bearing support and rotating shaft; Needle roller is located between the Internal and external cycle; Simultaneously, needle roller and inner ring and outer ring form rolling pair respectively, and retainer is located between inner ring and the outer ring; Neither participate in mechanical motion and also do not fix, just play the effect of needle roller at interval.Since adopt transition fit usually between inner ring, outer ring and the part that it links to each other separately, therefore, the dismounting inconvenience.And because existing rolling bearing is the ring enclosed construction, the rolling part can not contact with other part with the fixing part of bearing inner race again.Therefore, it is merely able to rotate, if need do relative translation, then need carry out specialized designs to bearing support; And the rolling part all need process the special step or the shaft shoulder, the processing relative complex.
Summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that existing technology exists, and a kind of semicircle needle bearing is provided, and it can be converted into translation with rotation smoothly, has reduced frictional force; Its Open architecture has made things convenient for dismounting.
The objective of the invention is to realize by following technological scheme:
A kind of semicircle needle bearing is provided with outer ring, retainer, it is characterized in that: this outer ring, retainer are Ω shape; The outer ring is located at the periphery of retainer; Wherein, retainer is provided with several needle roller mounting holes, and the outer ring of corresponding position is provided with several grooves; The needle roller mounting hole of retainer is installed needle roller with being located in the formed space of groove on the outer ring, through the above-mentioned semicircle Open architecture that connects and composes.
Said needle roller two ends respectively are provided with a step.
Beneficial effect of the present invention: the present invention is owing to adopt technique scheme, and it can be converted into translation with rotation smoothly, has reduced frictional force; Its Open architecture has made things convenient for dismounting, and owing to there is not the transition fit surface of contact, has reduced the difficulty of machining.
Description of drawings:
Fig. 1 is an overall structure schematic representation of the present invention.
Fig. 2 is a needle roller mounting structure schematic representation of the present invention.
Main label declaration among the figure:
1. outer ring, 2. retainer, 3. needle roller, 4. mounting hole, 5. outer ring mounting hole.
Embodiment
Like Fig. 1, shown in Figure 2, the present invention is provided with outer ring 1, retainer 2; Outer ring 1, retainer 2 are Ω shape, and wherein, outer ring 1 is located at the periphery of retainer 2; The two ends of retainer 2 are provided with mounting hole 4, and the two ends of outer ring 1 are provided with outer ring mounting hole 5, and retainer 2 adopts bolt connecting mode and outer ring 1 to fix; Retainer 2 is provided with several needle roller mounting holes, and the outer ring 1 of corresponding position is provided with several grooves, and installation needle roller 3 in the space that the needle roller mounting hole of retainer 2 and the groove that is located on the outer ring 1 form is through the above-mentioned semicircle Open architecture that connects and composes.Above-mentioned needle roller 3 two ends respectively are provided with a step.
Advantage of the present invention: the present invention is owing to adopt semicircle Open architecture; Cancelled bearing inner race,, rotational parts has directly been contacted with needle roller 3 through retainer 2 is fixing with outer ring 1; Simultaneously, rotational parts beyond bearing parcel district can with other plane contact.
The above; It only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technological scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. a semicircle needle bearing is provided with outer ring, retainer, it is characterized in that: this outer ring, retainer are Ω shape; The outer ring is located at the periphery of retainer; Wherein, retainer is provided with several needle roller mounting holes, and the outer ring of corresponding position is provided with several grooves; The needle roller mounting hole of retainer is installed needle roller with being located in the formed space of groove on the outer ring, through the above-mentioned semicircle Open architecture that connects and composes.
2. semicircle needle bearing according to claim 1 is characterized in that: said needle roller two ends respectively are provided with a step.
