How to judge the stability of rivet riveting

If the strut type rivet is bent and deformed due to instability under the action of the riveting pressure, the cage may be clipped and the bearing may not be rotated. Since the flexibility of the rivet bending in the thickness direction is large, it is only necessary to check the stability of the rivet in the thickness direction. The flexibility of the ring groove rivet bending in the thickness direction with less degree of use is: λ is the flexibility, μ is the height coefficient, i is the radius of inertia, and J is the moment of inertia of the rivet in the thickness direction.

When the rivet is riveted again, it can be seen that its lower end is fixed, and the upper end can only be rotated without rotating. Since the rivet is short, the flexibility is generally less than the flexibility of the corresponding material limit, so the rivet is a small flexible rod, so the critical stress of the rivet instability is the formula for the rivet stability check.

In the formula: the actual stability safety factor when riveting the rivet is the specified stability safety factor, generally taking 1.8-3.0, the working stress of the rivet. Ring groove rivets If the calculation results do not meet the above conditions, the stability of the rivet riveting is insufficient, and the stability of the rivet thickness S should be increased.

In the riveting, the rivet deformation and the misalignment of the two halves are easy to occur. Therefore, the parameters of the rivet and the cage should be reasonably selected during the design of the ring groove rivet, and the relevant check calculation should be carried out to avoid the phenomenon that the bearing ball and the rotation are inflexible.
