Abstract
The utility model discloses a novel cylindrical roller bearing, including outer lane, inner circle, holder and cylindrical roller, cylindrical roller is hollow cylinder, and cylindrical roller connects on the holder through its inside hollow pin who wears to establish, and has seted up on hollow pin's the middle part lateral wall rather than the communicating inlet port of inner chamber, having seted up a plurality of annular grooves on cylindrical roller's surface, having followed the circumferencial direction equipartition and be provided with a plurality of oil outlets in the annular groove, the oil outlet is linked together with cylindrical roller's hole. The utility model discloses set up the form into hollow structure with cylindrical roller, the whole through hardening of roller has effectively been guaranteed in the existence of roller hole, the even unanimity of hardness, and the mechanical properties of whole cross section is unanimous, has avoided the grinding burn of terminal surface, has effectively improved roller life.
Description
Technical field
The utility model belongs to technical field of bearings, particularly relates to a kind of novel roller bearing.
Background technique
Along with industrial development, increasing bearing is used in various machinery, roller is then indispensable component in machinery, the roller of current medium-and-large-sized roller bearing, when diameter is more than 30mm, because usual 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, be sliding contact friction between existing cylindrical roller and retainer, due to retainer, the lubricant oil of its inside easily flows out, thus causes lubrication 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 novel roller bearing.
In order to realize foregoing invention object, the utility model adopts technological scheme as described below:
A kind of novel roller bearing, comprise outer ring, inner ring, retainer and cylindrical roller, described cylindrical roller is hollow cylindrical, and the hollow bearing pin that cylindrical roller is worn by its inside is connected on retainer, and the middle part sidewall of hollow bearing pin offers the oil inlet hole communicated with its inner chamber; The outer surface of cylindrical roller offers some annular grooves, along the circumferential direction uniformly in annular groove is provided with some oil outlets, oil outlet is connected with the endoporus of cylindrical roller.
Further, the two-port of described hollow bearing pin is all covered with end cap.
Further, described oil inlet hole is circumferentially uniform is arranged on the outer surface of hollow bearing pin.
Owing to adopting technique scheme, the utility model has following superiority:
1, cylindrical roller is set to hollow-core construction form by the utility model, the existence of roller endoporus effectively ensure that the overall through hardening of roller, hardness uniformity, and the mechanical property of whole cross section is consistent, avoid the grinding burn of end face, effectively improve roller working life.
2, by injecting lubricant oil in hollow bearing pin, flow into cylindrical roller inside by oil inlet hole, lubricate entering into Bearing inner by oil outlet, it is efficient, convenient to lubricate, and effectively can play and extend bearing whole service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of cylindrical roller;
Fig. 3 is the structural representation of hollow bearing pin;
In figure: 1, outer ring; 2, inner ring; 3, retainer; 4, cylindrical roller; 4.1, annular groove; 4.2, oil outlet; 5, hollow bearing pin; 5.1 oil inlet hole.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As Figure 1-3, a kind of novel roller bearing, comprise outer ring 1, inner ring 2, retainer 3 and cylindrical roller 4, described cylindrical roller 4 is hollow cylindrical, the hollow bearing pin 5 that cylindrical roller 4 is worn by its inside is connected on retainer 3, and the middle part sidewall of hollow bearing pin 5 offers the oil inlet hole 5.1 communicated with its inner chamber; The outer surface of cylindrical roller offers some annular grooves 4.1, along the circumferential direction uniformly in annular groove 4.1 is provided with some oil outlets 4.2, oil outlet 4.2 is connected with the endoporus of cylindrical roller 4.
The two-port of described hollow bearing pin 5 is all covered with end cap.
Described oil inlet hole 5.1 is circumferentially on the uniform outer surface being arranged on hollow bearing pin 5.
The utility model is when needs lubricate, end cap on hollow bearing pin Single port is taken down, then internally lubricant oil is injected, the oil inlet hole of lubricant oil on hollow bearing pin flow into cylindrical roller inside, and flowing in annular groove by the oil outlet on cylindrical roller, along with relatively rotating of inside and outside circle and roller, and then play the effect of lubricating bearings inside; In addition, annular groove also can play the effect temporarily storing lubricant oil, prevents lubricant oil from directly flowing out and causing waste.
Claims (3)
1. a novel roller bearing, comprise outer ring, inner ring, retainer and cylindrical roller, it is characterized in that: described cylindrical roller is hollow cylindrical, the hollow bearing pin that cylindrical roller is worn by its inside is connected on retainer, and the middle part sidewall of hollow bearing pin offers the oil inlet hole communicated with its inner chamber; The outer surface of cylindrical roller offers some annular grooves, along the circumferential direction uniformly in annular groove is provided with some oil outlets, oil outlet is connected with the endoporus of cylindrical roller.
2. novel roller bearing according to claim 1, is characterized in that: the two-port of described hollow bearing pin is all covered with end cap.
