Abstract
The utility model relates to the technical field of bearings, in particular to a bearing provided with two rows of needle rollers arranged in parallel. The bearing provided with the double rows of the needle rollers is provided with a retainer made of cold-rolled carbon sheet steel and needle rollers made of high carbon chromium bearing steel, wherein the double rows of the needle rollers are embedded into the retainer in parallel; a plane concaving to the center of the bearing is arranged between every two adjacent needle rollers on the retainer; and annular grooves for accommodating seal rings are formed in two ends of an inner ring of the retainer. The bearing provided with the double rows of the needle rollers is simple in structure and reasonable in design; and the retainer made of the cold-rolled carbon sheet steel and the needle rollers made of the high carbon chromium bearing steel are adopted, so that the bearing is wear-resistant and long in service life.
Description
Technical field
The utility model relates to technical field of bearings, the bearing that especially a kind of two row's needle rollers are arranged side by side.
Background technique
Needle bearing (needle bearing) is the roller bearing with cylindrical roller, its diameter relatively, and not only carefully but also long, this roller is called needle roller to roller.Although there is less cross section, bearing still has higher load-bearing ability, needle bearing is equipped with thin and long roller, therefore radial structure is compact, when its internal diameter size is identical with other types of bearings with load-carrying ability, external diameter is minimum, is specially adapted to the radially restricted supporting result of installation dimension, therefore, needle bearing application is more and more extensive.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide a kind of simple in structure, the bearing of long service life.
The utility model solves the technological scheme that its technical problem adopts: a kind of duplex needle bearing, there is the needle roller that retainer that cold rolling carbon sheet plate makes and high-carbon-chromium bearing steel are made, double needle roller arranged side by side embeds in retainer, described retainer is provided with to the plane of bearing center of circle depression between adjacent two needle rollers, and retainer inner ring two ends are provided with the annular groove of placing seal ring.
Further, described retainer is provided with two depression planes.
Further, described retainer outward edge is fillet.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, and the needle roller that adopts retainer that cold rolling carbon sheet plate makes and high-carbon-chromium bearing steel to make is wear-resisting, long service life.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. retainers in figure, 2. needle roller, 11. annular grooves.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
Duplex needle bearing as shown in Figure 1, there is the needle roller 2 that retainer 1 that cold rolling carbon sheet plate makes and high-carbon-chromium bearing steel are made, double needle roller arranged side by side 2 embeds in retainer 1, and retainer 1 is provided with to the plane of bearing center of circle depression between adjacent two needle rollers 2; Retainer 1 is provided with two depression planes, and retainer 1 outward edge is fillet, and retainer 1 inner ring two ends are provided with the annular groove 11 of placing seal ring.
Above-mentioned mode of execution is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
