Abstract
The utility model relates to a hollow cylindrical roller bearing, which is characterized in that an outer ring with two retaining sides is arranged; an inner ring with no retaining side is arranged; a retainer is arranged and is formed by a retainer body and a retainer end cover connected with the retainer body on one side in an inserting way; a group of cylindrical rollers is arranged in a single row; and the cylindrical rollers are of hollow structures, each hollow structure is an axially penetrating through hole arranged in the center of the cylindrical roller, and the retainer body and the retainer end cover are combined with the cylindrical rollers through externally penetrating rivets penetrating through the through holes in the cylindrical rollers. The utility model has the advantages that the through quenching performance is ensured, no end surface grinding burn is caused, GCr15 material can be stilled used for rollers with diameter within 60mm, the cost is reduced, the service performance of the bearing is satisfied and the service life is improved.
Description
Technical field
The utility model relates to a kind of roller bearing, particularly a kind of medium-and-large-sized roller bearing.
Background technique
At present, the roller of medium-and-large-sized roller bearing, when diameter surpasses 30mm, from technical standpoint, must use the processing of GCr15SiMn Bearing Steel, otherwise, roller the hardness inequality will occur when quenching, defectives such as soft spots, the mechanical property of roller on whole cross section is mutually far short of what is expected, and the life-span reduces greatly.But in fact, in order to control cost, a lot of bearing enterprises for the roller of diameter below 45mm, all use the GCr15 material to do, therefore, the roller hardness lack of homogeneity, wear resistance is lower, and working life is short; Simultaneously, during the grinding roller end face, because grinding face is excessive, grinding heat distributes, and causes large-area burns, has had a strong impact on the working life of roller yet.
The model utility content
The utility model is for avoiding above-mentioned existing in prior technology deficiency, a kind of hollow cylindrical roller bearing is provided, guarantee the through hardening performance, do not cause the face grinding burn, for diameter at 60mm with interior roller, still use the GCr15 material, when reducing cost, satisfy the usability of bearing, improve the life-span.
The utility model technical solution problem adopts following technological scheme:
The utility model hollow cylindrical roller bearing, its structural feature are to be provided with:
An outer ring that has two ribs;
One with the inner ring of rib;
A retainer is made of the retainer body and a side retainer end cap of mutual grafting; Be the single-row one group of cylindrical roller that is provided with; Described cylindrical roller is a hollow-core construction, and described hollow-core construction is at the center of cylindrical roller the through hole that axially runs through to be set, and described retainer body and retainer end cap are to run through through hole in the cylindrical roller and cylindrical roller combination by wearing rivet outward.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model cylindrical roller is set to have the structural type of axial hole, the existence of axial hole has effectively guaranteed the whole through hardening of roller, hardness uniformity, the mechanical property unanimity of entire cross section, avoid the grinding burn of end face, effectively improved roller working life.
2, the utility model reduces cost greatly because therefore the whole through hardening of roller energy still can adopt the GCr15 material.
3, wearing rivet outside the utility model adopts between retainer body, retainer end cap and cylindrical roller makes up, therefore can shorten and be used on the retainer body forming the length that the retainer body of pegging graft carries rivet with the retainer end cap, reduce the friction between cylindrical roller and the retainer, improve the bearing running accuracy.

Number in the figure: 1 outer ring, 2 inner rings, 4 cylindrical rollers, 4a through hole, 6a retainer body, 6b retainer end cap, 6c carry rivet, 5 rivets.
Embodiment
Structure setting referring to Fig. 1 present embodiment comprises:
An outer ring 1 (shown in Figure 2) that has two ribs; One with the inner ring 2 of rib; A retainer is by the retainer body 6a (shown in Fig. 4 a, Fig. 4 b) and a side retainer end cap 6b (Fig. 5) formation of mutual grafting; Be the single-row one group of cylindrical roller 4 that is provided with; Cylindrical roller 4 is hollow-core construction (shown in Figure 3), hollow-core construction is that the through hole 4a that axially runs through is set at the center of cylindrical roller 4, and retainer body 6a and retainer end cap 6b make up by wearing through hole 4a and the cylindrical roller 4 that rivet 5 runs through in the cylindrical roller 4 outward.
Cylindrical roller in the present embodiment is set to hollow-core construction, and therefore circle is annotated roller and can be adopted the GCr15 made, and division center makes its whole through hardening that can guarantee cylindrical roller, hardness uniformity, the mechanical property unanimity of entire cross section.Also eliminate the sonims at roller material center simultaneously, improved the working life of roller.
Compare and prior art, the rivet 6c that carries on the retainer body 6a that is used in the present embodiment pegging graft with retainer end cap 6b can shorten relatively, guarantees that mutual positioning instant therebetween can.
