Abstract

The utility model discloses a bearing retainer which comprises a retainer main body integrally formed by a lintel and a bottom cover and an end cover connected with the retainer main body. A screw for fixing the end cover is positioned at the upper end of the lintel, and the screw is inserted into a connection through hole of the end cover and in thread connection with a corresponding nut. Due to the fact that the screw integrated with the lintel is positioned at the upper end of the lintel, processing process is simplified. The screw is made of lintel materials, so that the connection strength with the end cover is greatly increased compared with a rivet.

Description

Retainer

Technical field

The utility model relates to a kind of retainer, particularly a kind of retainer of being convenient to process.

Background technique

Fig. 1 has shown a kind of existing solid bearing cage, this solid bearing cage is comprised of end cap 3, body and rivet 6, space in the retainer is called fenestra 2, in order to lay and to guide rolling element, attachment portion between the fenestra is called lintel 1, it also plays the effect that increases retainer intensity except connecting two fenestras.Lintel 1 is made of one with bottom 5, is called body.During assembling, rivet is inserted in the rivet hole of end cap and body, then rivet and gland and the body of retainer can be linked together.

Above-mentioned solid bearing cage has following shortcoming:

1, difficulty of processing is large.This structure retainer is because the existence of rivet and rivet hole can only be adopted machining production, and master operation is Vehicle Processing, so be called again car retainer processed.Need to adopt spun casting to become pipe, then can be shaped through ten multi-step process, technique is very complicated.

2, stock utilization is low.Employing machining is produced, and stock utilization is less than 20%, and a large amount of valuable Cuprum alloys is become smear metal and slatterns, and processing cost is increased greatly.

3, part performance is low.Owing to adopted cast blank, its tissue defects that its mechanical property is affected, and because of the existence of sand holes and pore, be easy to cause parts scrap.In addition, size-constrained because of rivet, the end cap of retainer and the join strength of body are affected.

4, usability and the life-span of bearing have been reduced.The existence of rivet has increased the thickness of lintel, has tied up the useful space of retainer fenestra, the diameter of rolling element is reduced or quantity reduces, thus bearing capacity and the rating life of having reduced bearing.

Summary of the invention

The utility model proposes a kind of retainer of being convenient to process for the problem of above-mentioned prior art.

A kind of retainer of the present utility model comprises: the retainer body that is consisted of by lintel and bottom one, and the end cap that connects described retainer body, wherein:

The upper end of described lintel has the screw rod that is used for fixing described end cap; And

Described screw rod inserts in the connecting through hole of described end cap, and connects with corresponding nut thread.

Preferably, the connecting through hole of described end cap comprises passing first through hole and the second through hole that is used for settling described nut of described screw rod.

Preferably, the diameter of described the second through hole is greater than the diameter of the first through hole.

Preferably, described screw rod extends upwardly extension from the lintel main body, and its material is identical with the lintel main material.

With respect to prior art, the utlity model has following technique effect:

1, in the lintel upper end screw rod integrally formed with lintel is set, simplified processing technology;

2, because screw rod adopts identical material manufacturing with lintel, and screw strength is guaranteed, thereby can increase the join strength with end cap;

3, because retainer has saved original special-purpose rivet, can reduce the thickness of lintel, save the useful space, the diameter of rolling element or quantity are increased, thus bearing capacity and the rating life that can improve bearing.

Below in conjunction with accompanying drawing the utility model is elaborated.

Description of drawings

Fig. 1 is existing solid bearing retainer structure schematic representation;

Fig. 2 is the schematic representation of retainer of the present utility model;

Fig. 3 is the structural representation of a lintel shown in Figure 2.

Embodiment

Fig. 1 has shown the structure of retainer of the present utility model, as shown in Figure 1, comprising:

The retainer body that is consisted of by lintel 1 and bottom 5 one, and the end cap 3 that connects described retainer body.

Fig. 2 has shown the beam structure of crossing of the present utility model, and as shown in Figure 2, lintel 1 upper end has the screw rod 4 that is used for fixing end cap 3, and screw rod 4 is inserted in the connecting through hole of end cap 3, and is threaded with corresponding nut 7.

The second through hole that the connecting through hole of end cap 3 comprises passing the first through hole of described screw rod 4 and is used for settling nut 7.The diameter of the second through hole should be greater than the diameter of the first through hole.

Screw rod 4 of the present utility model extends upwardly extension from lintel 1 main body, and its material is identical with the lintel main material.Because screw rod 4 adopts the material of lintel 1, the material than making rivet can increase its join strength greatly.

Because lintel of the present utility model upper end arranges the screw rod integrally formed with lintel, thereby has simplified processing technology;

Because the utility model screw rod adopts identical material manufacturing with lintel, screw strength is guaranteed, and can increase the join strength with end cap;

Because model utility has saved the special-purpose rivet of original retainer, can reduce the thickness of lintel, saved the useful space, the diameter of rolling element or quantity are increased, thus bearing capacity and the rating life that can improve bearing.

Although above the utility model is had been described in detail, the utility model is not limited to this, and those skilled in the art of the present technique can carry out various modifications according to principle of the present utility model.Therefore, all modifications of doing according to the utility model principle all should be understood to fall into protection domain of the present utility model.

Claims
