Under the influence of the riveting working pressure, if the supporting bolt has winding deformation due to imbalance, it will also produce the ball clamping of the connecting frame, and the rolling bearing will not rotate quickly. Because the flexibility of the bolt in the thin and thick base mark is large, all iron rivet only needs to check the bolt in the thin and thick base mark. The flexibility of the ring groove bolt in the low cost thin and thick base mark is: λ is the flexibility, μ is the height width ratio index, I is the inertia force semicircle, j is the bending rigidity of the bolt in the thin and thick base mark target.

When the bolt is riveted for the second time, it can be regarded as solid below, and the upper part can only be translated, and the change surface is not ejected. Because the bolt is short, its flexibility is generally lower than the compliance limit of the matching material, so the bolt is a small flexibility rod. Therefore, the critical value of in-situ stress of bolt imbalance is calculated by the formula of constant correction of bolt end compression bar. In the formula: it refers to the fact that the calm index will not change when the bolt is riveted and pressed, and it will not change the calm index for the divided one, generally taking 1.8-3.0. If the all iron countersunk head rivet ring groove bolt does not meet the above preconditions, it is stated that the bolt riveting time is not enough, and the bolt thickness s should be increased in the whole process to develop its unchanged.

The stiffness of the shallow pocket wave type interconnector is weak, and it is easy to produce bolt deformation and displacement of two sections of mutual connecting frame during riveting. Therefore, the main parameters of bolts and interconnectors should be selected fairly and relevant checking should be terminated when the ring groove bolt is conceived, so as to prevent rolling bearing from showing ball clamping and inflexible rotation.
