る。Hereinafter, the non-separable cross roller bearing 1 shown in FIG.
0 will be described. First, after the rollers 41 are arranged around the inner ring 31, the first and second rings 23 and 24 are fitted to the outside of the inner ring 31. Then, the pin portion 83 of the rivet 8 is pushed into the rivet hole 24 a formed in the second ring 24. At this time, the non-fastened portion 83a of the pin portion 83 and the rivet hole 24a are fitted without looseness by the interference, and a slight gap is formed between the fastened portion 83b and the rivet hole 23a. Is done. Next, the front end of the fastening portion 83b of the rivet 81 is swaged by electric heating and pressure to fasten the two rings 23 and 24, thereby forming the outer ring 21.
Is completed, and at the same time, rollers 41 are provided between the outer ring 21 and the inner ring 31.
Is held. When the tip of the fastening portion 83b of the rivet 81 is swaged, an axial compressive force acts on the fastening portion 83b. However, since the non-fastened portion 83a of the pin portion 83 is provided with an interference margin, the non-fastened portion 83a is not deformed. On the other hand, since a gap is formed on the fastening portion 83b side of the pin portion 83, there is a possibility that some deformation occurs in the fastening portion 83b, but a gap is formed over the entire length of both rivet holes. The rivet 81 is less likely to buckle since the length of the gap is about し て of that in the conventional case, and a sufficient crimping load is obtained when the two rings 23 and 24 are fastened. Can be. here,
The reason why a gap is provided on the side of the fastening portion 83b is that both rings 2
This is to allow the first ring 23 of one of the rings 3 and 24 to move and align and fix the first ring 23 at mutually optimal positions.

Instead of having an interference between the rivet and the rivet, it is conceivable to prevent the buckling by increasing the entire pin portion of the rivet, but in this case, the inner diameter of the rivet hole is increased by increasing the diameter of the pin portion. Also have to be large. On the other hand, in the case of the above-described embodiment, the inner diameter of the rivet holes 23a and 24a can be the same as the conventional one, and there is no possibility that the rated load of the bearing is sacrificed. Further, instead of providing a margin between the non-fastened portion 83a and the rivet hole 24a, it is conceivable to fasten the two rings 23, 24 with bolts and nuts, but the number of steps increases. on the other hand,
In the case of the above embodiment, the rivet 81 is inserted into the rivet hole 23.
It is only necessary to perform riveting through the holes a and 24a, and the productivity of the bearing can be increased.
