Abstract
The utility model relates to a riveting bearing retainer. The riveting bearing retainer comprises a semi-closed retainer (1) and an end cover (2), wherein one end of the semi-closed retainer is a closed end, the other end of the semi-closed retainer is an open end, two end surfaces of the semi-closed retainer in the axial direction respectively have a plurality of pocket holes, the aperture of each pocket hole is already determined, a cylindrical rivet head (1.1) is arranged between two adjacent pocket holes on the open end, the aperture and the length of each cylindrical rivet head are identical, the cylindrical rivet heads have identical central diameter, the end cover with the outer diameter, inner diameter and width being identical to that of the closed end is in butt joint to the open end of the semi-closed retainer through an end cover hole in the closed end, the end cover is connected with the semi-closed retainer through the riveting between a rivet ring (3) and the cylindrical rivet head, and since the cylindrical rivet heads are regular in shape, the riveting current of an electric riveting machine is easy to control, the cylindrical rivet heads are uniformly stressed, the semi-closed retainer hardly deforms, and the structural strength of the riveting bearing retainer can be improved.
Description
Technical field
The utility model belongs to technical field of bearings, refers more particularly to a kind of riveted type retainer.
?
Background technique
Roller bearing is more with the structure type of retainer, to internal diameter greater than 150mm and require at a high speed or turn round stably that bearing adopts solid cage more, solid cage is a car manufacture-yellow copper cage, the brass retainer mostly is opens two halves formula structure, the side's of employing rivet is implemented riveted joint, because the out-of-shape and the riveted electric current of square rivet are wayward, rivet be heated inequality or cause retainer burnt distortion even cracking in the side's of causing has had a strong impact on the up-to-standard rate of bearing assembling.
?
Summary of the invention
For addressing the above problem, the utility model has designed a kind of riveted type retainer, and the problem that has existed when having solved square rivet has improved the up-to-standard rate of roller bearing assembling.
For achieving the above object, the utility model adopts following technological scheme:
A kind of riveted type retainer, comprise semiclosed retainer and end cap, one end of semiclosed retainer is a closed end and the other end is the open end, in even several pocket holes that is furnished with of the axial both ends of the surface of semiclosed retainer, the aperture in several pocket holes is fixed, between the pocket hole of described open end and pocket hole, be provided with cylindrical die, the external diameter of these cylindrical dies is with identical length etc. and have identical central diameter, with described closed end external diameter, the end cap that internal diameter and width equate is docked at the described open end of semiclosed retainer by the ending cover hole that disposes it on, by the riveting ring and the riveted joint of cylindrical die end cap is connected with semiclosed retainer again.
Described ending cover hole is divided into die hole and annular groove, the internal diameter in described die hole and the external diameter of cylindrical die coupling, these described die holes have identical central diameter and mate with the central diameter of cylindrical die, the external diameter of the width of described annular groove 〉=riveting ring, the thickness coupling of the degree of depth of described annular groove and riveting ring.
Owing to adopt technological scheme as mentioned above, the utility model produces following beneficial effect:
1, the utility model does not change the basic structure size of cylinder roller bearing retainer, and the problem that has existed when having solved square rivet has improved the up-to-standard rate of roller bearing assembling.
2, owing to the shape comparison rule of cylindrical die, the riveted electric current of electric riveting machine is easy to control, and cylindrical die is stressed evenly to make semiclosed retainer not yielding, has improved the structural strength of riveted type retainer.

Embodiment
The utility model is a kind of riveted type retainer, comprise semiclosed retainer 1 and end cap 2, one end of semiclosed retainer 1 is a closed end and the other end is the open end, in even several pocket holes that is furnished with of the axial both ends of the surface of semiclosed retainer 1, the aperture in several pocket holes is fixed, and the basic parameter of semiclosed retainer is identical with the basic parameter of former retainer.
In conjunction with Fig. 1-5, the utility model is provided with cylindrical die 1.1 between the pocket hole of described open end and pocket hole, the external diameter of these cylindrical dies 1.1 is with identical length etc. and have identical central diameter, the end cap 2 that equates with described closed end external diameter, internal diameter and width is docked at the described open end of semiclosed retainer 1 by the ending cover hole of configuration on it, by the riveting ring 3 and the riveted joint of cylindrical die 1.1 end cap 2 is connected with semiclosed retainer 1 again.
Described ending cover hole is divided into die hole and annular groove 2.1, the internal diameter in described die hole and the external diameter of cylindrical die 1.1 coupling, these described die holes have identical central diameter and mate with the central diameter of cylindrical die 1.1, the external diameter of the width of annular groove 2.1 〉=riveting ring 3, the thickness coupling of the degree of depth of annular groove 2.1 and riveting ring 3.
Retainer riveting when dress with after-frame with, the gear-shaping retainer, the opening that earlier semiclosed retainer 1 is kept flat and makes described open end up, alignd with the cylindrical die 1.1 of semiclosed retainer 1 in several described die holes of end cap 2 again and pack into, the annular groove 2.1 of end cap 2 also makes the end cap 2 and the described open end of semiclosed maintenance stand 1 be close to up, riveting ring 3 is riveted on the close-coupled that can realize end cap 2 and semiclosed retainer 1 on the cylindrical die 1.1 with electric riveting machine then, and the shape comparison rule of cylindrical die 1.1, the riveted electric current of electric riveting machine is easy to control, cylindrical die 1.1 is stressed evenly, make semiclosed retainer 1 not yielding, improved the structural strength of riveted type retainer.
