Abstract
The utility model relates to a needle bearing which comprises roller paths, wherein a plurality of roller needles are axially distributed on the roller paths around axes of the roller needles , the roller needles are mutually separated by a trapezoid retainer, flanges used for fixation are arranged on two sides of each roller needle, and gaps are reserved between the roller needles and the roller paths. The roller needles of the needle bearing are mutually separated by the trapezoid retainer, so that the service life of the bearing is prolonged greatly.
Description
Technical field
The utility model relates to a kind of needle bearing.
Background technique
Common needle bearing cage mostly is yi word pattern structure, unavoidable generation deviation, the working life of greatly reducing bearing between needle roller after long-time use.
Model utility content
The technical problems to be solved in the utility model is: for solving the problem of above-mentioned existence, provide a kind of needle bearing, solve low problem of plain bearing life-span.
The utility model solves the technological scheme that its technical problem adopts: a kind of needle bearing, comprise raceway, on raceway around centerline axis to being distributed with a plurality of needle rollers, between needle roller, by trapezoidal retainer, mutually separate, needle roller both sides are provided with for fixing rib, between needle roller and raceway, leave gap.
Raceway outer surface edge adopts fillet to process.
The beneficial effects of the utility model are, between roller bearing needle of the present utility model, by trapezoidal retainer, mutually separate, thus the working life of greatly improving bearing.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. raceways in figure, 2. needle roller, 3. retainer, 4. rib.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
A kind of needle bearing as shown in Figure 1, comprises raceway 1, on raceway 1 around centerline axis to being distributed with two needle rollers 2, between needle roller 2, mutually separate by trapezoidal retainer 3, needle roller 2 both sides are provided with for fixing rib 4, between needle roller 2 and raceway 1, leave gap.
Raceway 1 outer surface edge adopts fillet to process.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this model utility technological thought, carry out various change and modification completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to claim scope.
