Abstract
The utility model discloses a hollow cylindrical roller comprising a roller body, wherein the roller body is of a hollow cylindrical structure; a plurality of annular arc grooves are formed on the outer surface of the roller body; a plurality of oil holes are uniformly formed in the annular arc grooves in a circumference direction; the oil holes are communicated with an inner hole of the roller body. The hollow cylindrical roller disclosed by the utility model, through the cylindrical roller which is in the form of a hollow structure, guarantees integral through hardening of the roller because of existence of roller inner hole, keeps consistent and uniform hardness and consistent mechanical performance of entire cross section; the hollow cylindrical roller avoids grinding burn of end face and the service life of the roller can be effectively prolonged.
Description
Technical field
The utility model belongs to technical field of bearings, relates in particular to a kind of hollow cylindrical roller.
Background technique
Along with industrial development, increasing bearing is used in various machinery, roller is indispensable component in machinery, the roller of current medium-and-large-sized roller bearing, when diameter surpasses 30mm, because common roller is solid construction, roller tend when quenching occurs that hardness is uneven, the defects such as soft spots, the mechanical property of roller on whole section of diameter is mutually far short of what is expected, and the life-span reduces greatly; In addition, between existing cylindrical roller and retainer, be sliding contact friction, due to retainer, its inner lubricant oil easily flows out, thereby causes lubricated insufficient.
Summary of the invention
In order to solve the problems of the prior art, the object that the utility model is adopted is to provide a kind of hollow cylindrical roller.
In order to realize foregoing invention object, the utility model adopts technological scheme as described below:
A kind of hollow cylindrical roller, comprise roller body, roller body is hollow cylindrical, offers some annular arc grooves on the outer surface of roller body, along the circumferential direction uniformly in annular arc groove be provided with some oilholes, oilhole is connected with the endoporus of roller body.
Owing to adopting technique scheme, the utlity model has following superiority:
1, the utility model cylindrical roller is set to hollow-core construction form, the existence of roller endoporus has effectively guaranteed the whole through hardening of roller, hardness uniformity, and the mechanical property of whole cross section is consistent, avoid the grinding burn of end face, effectively improved roller working life.
2, by annular arc groove is set at roller surface, and oilhole is set in groove, when lubricant oil is more sufficient, flows in groove and by oilhole, enter in the endoporus of roller, can play and stop that lubricant oil slips away and store the dual functions of lubricant oil.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-roller body; 2-annular arc groove; 3-oilhole.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, a kind of hollow cylindrical roller, comprises roller body 1, roller body 1 is hollow cylindrical, on the outer surface of roller body, offer annular arc groove 2, along the circumferential direction uniformly in annular arc groove be provided with some oilholes 3, oilhole is connected with the endoporus of roller body.
Claims (1)
1. a hollow cylindrical roller, comprise roller body (1), roller body is hollow cylindrical, it is characterized in that: on the outer surface of roller body, offer annular arc groove (2), uniform some oilholes (3) that are provided with along the circumferential direction in annular arc groove, oilhole is connected with the endoporus of roller body.
