Abstract
The present invention relates to a kind of retainer clinching methods.The major part part of the major part part of pin and the T-shape hole of retainer is interference fitted, microcephaly's portion gap cooperation in the T-shape hole of pin bar part and retainer；The anti-rivet abjection structure that a circle bends inwards is processed around the T-shape hole of retainer.A kind of new retainer clinching method using the present invention may be such that the intensity of retainer is greatly improved, so as to extend the service life of bearing.
Description
Technical field
The invention belongs to technical field of bearings, and in particular to a kind of new retainer clinching method.
Background technology
Oil plays the role of very important in national economy, and in recent years, petroleum machinery has also welcome rapid development, than
Such as pumping unit, Pulp pump, slush pump, drilling platforms.Wherein, cylinder roller bearing will be used, is well imagined, such operating mode
Must be severe, vibration, noise are above other industry bearing, therefore, it is necessary to be redesigned to adapt to bearing arrangement
Such operating mode.
According to investigations, such operating mode bearing damage form is mostly the fracture of retainer riveting portion, because in the case where vibrating occasion, is protected
Frame is held to stand in the breach.Therefore, it is necessary to the riveting method of retainer is further studied.
During assembling, pin needs to be coordinated through the beam of retainer and the cylindrical hole of roller, is rotated with guide rolls, because
This part of this retainer is most weak during the work time.
The content of the invention
The present invention provides a kind of new retainer riveting method to solve bearing retainer caulking part during work
The problem of dividing easy fracture.
The present invention is that technical solution is to provide a kind of new retainer riveting method used by solving its technical problem, will
The major part part in the major part part of pin and the T-shape hole of retainer is interference fitted, " T " of pin bar part and retainer
Microcephaly's portion gap cooperation of type hole；The inside bending structure of a circle is processed around the T-shape hole of retainer to prevent riveting
Nail abjection.
A kind of new retainer clinching method using the present invention may be such that the intensity of retainer is greatly improved, from
And extend the service life of bearing.
Description of the drawings
Fig. 1 is a kind of cylinder roller bearing retainer structure diagram with new riveting method.
Fig. 2 is pin and the partial enlarged view of retainer riveting.
Fig. 3 deviates from structure diagram for the anti-pin in T-shape hole.
2nd, rolling element, 1, pin, 3, integrated cage, 1-1, pin major part part, 1-2, pin shank.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated.
It is a kind of cylinder roller bearing retainer structure diagram with new riveting method as shown in Figure 1.Including one
Frame 3 and rolling element 2.During installation, pin 1 is coordinated through retainer 3 and the cylindrical hole of rolling element 2, rolling element 2 to be guided to revolve
Turn, therefore this part of retainer 3 is most weak during the work time.
The concrete mode of riveting is as shown in Fig. 2, by the major part part 1-1 of pin 1 and the major part in the T-shape hole of retainer 3
Part is interference fitted, and such shock resistance will improve.The small head of pin shank 1-2 parts and the T-shape hole of retainer 3
Subdivided gap coordinates.Pin during installation is gently put into T-shape hole, is pressed pin 1 as in T-shape hole with forcing press.
After pin 1 is installed, add as shown in figure 3, the instruments such as cross chisel can be used around the T-shape hole of retainer 3
Work goes out the anti-rivet abjection structure that a circle bends inwards, so as to which retainer 3 be locked.
A kind of new retainer clinching method using the present invention may be such that the intensity of retainer is greatly improved, from
And extend the service life of bearing.
