Abstract
The utility model discloses an improved structure of a cage end cover with a rivet entity, comprising an end cover and rivet holes (2) distributed in a circle along the end cover (1). The lower part of the rivet hole (2) is matched suitably with the section shape of the rivet of the cage body; the section size of the middle part is enlarged; the upper part of the rivet hole (2) adopts the structure of material containing chamber whose section size is larger than the section size of the middle part of the rivet hole. The upper part of the rivet hole on the end cover adopts the structure of material containing chamber, and thus the requirement of the subsequent riveting operation is reduced without influence on riveting strength or appearance of the riveted joint, ensuring that the joint riveted is lower that the upper end surface of the rivet hole. The utility model which has the advantages of high joint strength and beautiful appearance is convenient for riveting.
Description
Affiliated technical field
The utility model belongs to the retainer technical field, and what relate generally to is a kind of improvement structure that carries rivet solid bearing cage end cap.
Background technique
The known rivet solid bearing cage that carries is compared with special-purpose rivet retainer, carries the rivet retainer its mechanical property and riveted joint performance are improved greatly.But since its end cap on rivet also with the retainer body on rivet basic identical, so just make that the joint material after riveting partly is positioned at the top of end cap, not only out-of-shape is difficult to form riveted joint shape attractive in appearance, and its anti-shear ability and riveting intensity remain further to be improved.For this reason, " carrying the retainer end cover structure of rivet " that the inventor has applied for, by changing the sectional shape on end cap rivet hole top, increase the volume of rivet hole, thereby when riveted joint, rivet produces plastic deformation and is full of in it, and forms wedge-shaped structure, improved its anti-shear ability and riveting intensity, and the riveted joint beautiful shape.But this structure is had relatively high expectations to follow-up riveting process, be that rivet size dimension on the retainer body must be accurately, and make the size of rivet impossible identical because of machining error in the actual processing, part rivet joint after causing riveting still exceeds the end cap end face, influence its outward appearance and usability, so also need adopt the polishing working procedure processing, increase manufacturing procedure.
Summary of the invention
The purpose of this utility model promptly produces thus, proposes a kind of improvement structure that carries rivet solid bearing cage end cap, further improves its assembly performance, usability and performance attractive in appearance, reduces the requirement to follow-up riveting step.
For achieving the above object, the technological scheme that the utility model is taked is: carry on the architecture basics of rivet solid bearing cage existing, to be designed to along the rivet hole bottom of end cap circle distribution to join with the sectional shape of retainer body rivet kiss, the sectional dimension at middle part enlarges, top is the material-holding chamber structure, the sectional dimension of this material-holding chamber is greater than the sectional dimension at middle part.
The utility model design is unique.Because it is the material-holding chamber structure with the rivet hole upper design on the end cap, like this, under the prerequisite that does not influence riveting intensity and riveted joint beautiful shape, reduced requirement to follow-up riveting step, guarantee that the joint after the riveted joint does not exceed the upper-end surface of rivet hole, have the joint strength height, be convenient to rivet, the characteristics of beautiful shape.

Embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As Fig. 1 in conjunction with shown in Figure 2, present embodiment is to carry on the architecture basics of rivet solid bearing cage existing, will along the rivet hole 2 bottom section shaped design of end cap 1 circle distribution for the retainer body on the rivet shape kissing join, the sectional dimension at middle part enlarges, top is the material-holding chamber structure.The cross section chi shape at its middle part can be: as shown in Figure 5, sectional dimension enlarges gradually from bottom to top, and makes overbank, and its gradient is 8-16 °; As shown in Figure 6, it is on the basis of Fig. 5, makes straight flange in the bottom of transition zone, and the rivet shape kissing on its sectional shape and the retainer body is joined; As shown in Figure 7, it is on the basis of Fig. 6, has designed straight section again on the top of transition zone; As shown in Figure 8, its to be that inclined-plane with Fig. 5 excessively becomes convex globoidal excessive; As shown in Figure 9, its to be that inclined-plane with Fig. 5 excessively becomes concave arc surface excessive; As shown in figure 10, it is excessive that it is that inclined-plane with Fig. 5 excessively becomes step, and the rivet shape kissing on the sectional shape of its underpart straight section and the retainer body is joined.The size of the material-holding chamber on top is greater than the sectional dimension at rivet hole middle part and the sectional dimension of riveting machine riveted head, like this when riveted joint, the riveted head of riveting machine can stretch into the material-holding chamber of rivet hole and realize riveted joint, makes rivet joint area complete filling after the riveted joint in the middle part or material-holding chamber of rivet hole.The sectional shape of material-holding chamber can be circle, ellipse, rectangle etc.For ease of processing, adjacent material-holding chamber can be designed to connectivity structure, thereby form annular groove 3 structures (as shown in Figure 3-4) on end cap top, the width of this annular groove 3 is greater than the respective width of rivet hole.During assembling, end cap is fastened on the rivet 4 that retainer body 5 carries by its rivet hole, and riveted joint back rivet produces plastic deformation and is full of rivet hole and forms riveted joint structure (shown in Figure 11～15).Because the setting of material-holding chamber, the joint of rivet can not exceed the end face of end cap, and its assembly performance, usability and performance attractive in appearance are further enhanced.
