Abstract
The utility model relates to a fastened rivet for riveting the ball bearing holder of a centripetal ball, belonging to the field of the mechanical technology. The nail rod of the fastened rivet is divided into two parts of a fastening rod and a loosening rod; the fastening rod is positioned at the upper end of the loosening rod, and is connected with a screw cap; the diameter of the fastening rod is larger than that of the loosening rod, and a transition chamfer angle is arranged between the fastening rod and the loosening rod. The ball-bearing is assembled by the fastened rivet with high production efficiency, decreased labor intensity and improved bearing assembly accuracy.
Description
The utility model relates to the rivet that the retainer riveted of radial ball bearing is used, and belongs to field of mechanical technique.
The existing bearing rivet is loose rivet, and the nail bar identical with diameter by the head of a nail constitutes, and the diameter of nail bar during assembling, causes the retainer dislocation less than retainer rivet aperture easily, influences the riveted precision, causes the flexibility of revolution of bearing poor, and noise is big.Existing rivet only is adapted to the manual operations assembling, inefficiency, and labor intensity is big.
The purpose of this utility model is exactly the deficiency that will overcome existing bearing rivet, and a kind of tight rivet of bearing of reducing nail bar is provided.
The purpose of this utility model is achieved in that the tight rivet of bearing is to improve to form on the basis of existing straight-bar type pine rivet, it is characterized in that following closely bar and be provided with tight bar and loose bar, the upper end that tight bar is positioned at loose bar is connected with the head of a nail, tight shank diameter is greater than loose shank diameter, tight bar and retainer hole interference fit, tight pole length is more than or equal to the thickness of retainer ring, and tight bar and loose bar connecting place are provided with the transition chamfering.
The utility model is simple and reasonable for structure, and is easy to manufacture, easy to use, is applicable to that mechanization, automation bearing assembly line use, and enhances productivity, and reduces labor strength, improves the bearing assembly precision, and the excellent popularization using value is arranged.
Accompanying drawing is a structural representation of the present utility model, 1 head of a nail, 2 tight bars, 3 loose bars, 4 transition chamferings among the figure.
Narrate an embodiment of the present utility model below in conjunction with accompanying drawing.
The nail bar of the tight rivet of bearing is established tight bar and loose bar, and the upper end that tight bar is positioned at loose bar is connected with the head of a nail, and tightly shank diameter is greater than loose shank diameter, tightly bar and retainer hole interference fit.Tight pole length is more than or equal to the thickness of retainer ring, and the transition chamfering is adopted in tight bar and loose bar joint, and loose rod end is also established chamfering.
