Abstract
The utility model relates to the technical field of bearings, in particular to a lubricating type bearing provided with double rows of needle rollers. The bearing is provided with a retainer made of cold-rolled carbon sheet steel and the 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 oil injection holes are formed in the planes. The lubricating type bearing provided with the double rows of the needle rollers is simple in structure and reasonable in design; 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; and the oil injection holes are formed, so that the lubricating property is good.
Description
Technical field
The utility model relates to technical field of bearings, especially a kind of lubricating type duplex needle bearing.
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 lubricating type 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 described plane is provided with oil hole.
Further, described retainer is provided with two depression planes.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, the needle roller that adopts retainer that cold rolling carbon sheet plate makes and high-carbon-chromium bearing steel to make, and wear-resisting, long service life, is provided with oil hole, and greasy property is good.
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. oil holes.
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.
Lubricating type 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, retainer 1 is provided with to the plane of bearing center of circle depression between adjacent two needle rollers 2, and plane is provided with oil hole 11; Retainer 1 is provided with two depression planes
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.
Claims (2)
