Abstract

The utility model relates to the technical field of bearings, in particular to a single-row cylindrical roller bearing. The single-row cylindrical roller bearing comprises a bearing outer ring, a bearing inner ring and a rolling needle, wherein a holder is arranged between the bearing outer ring and the bearing inner ring; the rolling needle is movably embedded into the holder; circular rolling paths are arranged on the bearing outer ring and the bearing inner ring; two arc grooves which a lubricating oil can be inserted into are formed in a rolling path of the bearing inner ring; and a stopping groove is formed in the outer surface of the bearing outer ring. The single-row cylindrical roller bearing is simple in structure and reasonable in design; the holder made of brass and the bearing outer ring, the bearing inner ring and the rolling needle which are made of high carbon chromium bearing steel are adopted, and the single-row cylindrical roller bearing is abrasion-resistant and long in service life.

Description

Single row roller bearing

Technical field

The utility model relates to technical field of bearings, especially a kind of single row roller 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 single row roller bearing, there is bearing outer ring, bearing inner race and needle roller, between described bearing outer ring and bearing inner race, be provided with retainer, the movable retainer that embeds of needle roller, on bearing outer ring and bearing inner race, be equipped with ring raceway, raceway on described bearing inner race is provided with two arc grooves that can inject lubricant oil, and described bearing outer ring outer surface is provided with locking groove.

Further, described bearing outer ring, bearing inner race and needle roller material are high-carbon-chromium bearing steel, and described retainer is brass retainer.

The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, and bearing outer ring, bearing inner race and needle roller that the retainer that employing brass is made and high-carbon-chromium bearing steel are made are 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. bearing outer rings in figure, 2. bearing inner race, 3. retainer, 4. needle roller, 11. locking grooves, 21. arc 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.

Single row roller bearing as shown in Figure 1, there is bearing outer ring 1, bearing inner race 2 and needle roller 4, between bearing outer ring 1 and bearing inner race 2, be provided with retainer 3, the movable retainer 3 that embeds of needle roller 4, on bearing outer ring 1 and bearing inner race 3, be equipped with ring raceway, raceway on bearing inner race 2 is provided with two arc grooves 21 that can inject lubricant oil, and bearing outer ring 1 outer surface is provided with locking groove 11; Retainer 3 is brass retainer.

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.
