る。[0005] As described above, each trunnion 51 has:
A bearing device 6 having a plurality of rollers is used. When transmitting a rotating torque from one rotating shaft 1 to the other rotating shaft, a cross shaft from one yoke 2 via a bearing case 62 is used. 5, a load acts on the two trunnions 51, and the other two trunnions 51 of the cross shaft 5
A load acts on the other yoke 4 via the second yoke 4. In this case, in each of the trunnions 51, the bending displacement amount (bending amount) at the distal end becomes large. Therefore, the rollers 63a at the base end side, the rollers 63b at the center part, and the rollers 63 at the distal end side of the trunnion 51.
There is a difference between c and the applied load. Therefore, as shown in FIG. 6, the loads applied to the rollers at the base end and the tip end of the trunnion 51 are made equal, that is,
The diameters (d 1 , d 2 , c 3) of these rollers 63 a, 63 b, 63 c are such that gaps c 1 , c 2 corresponding to the amount of bending displacement of 1 are generated.
d 2, d 3) were made different to Yuniba - monkeys joint has been proposed (Kokoku No. 3-1531). Although the actual difference between the roller diameters is small, the difference between the roller diameters is exaggerated in FIG. 6 so as to be clearly understood for the sake of explanation.

Will not be mistaken. That is, when these rollers 11a, 11b, and 11c are set up and arranged, the difference in length between these rollers 11a, 11b, and 11c becomes apparent to the operator at a glance. Therefore, between the trunnion 51 and the bearing case 62, the rollers 11
When a, 11b, and 11c are incorporated, the rollers 11a disposed on the base end side of the trunnion 51, the rollers 11b disposed on the intermediate part, and the rollers 11c disposed on the distal end side of the trunnion 51 are not mistaken. It is possible to incorporate the components accurately without any complication.

なる。The universal joint bearing device of the present invention is constructed as described above. Next, the displacement of the trunnion 51 during the transmission of the rotational torque and the clearance between the trunnion 51 and 11a, 11b, 11c are determined. Will be described. FIG. 3A is a partial sectional view of the universal joint bearing device of the present invention in a state where no load is applied to the trunnion 51 of the cross shaft 5. In this state, the rollers 11 arranged at the intermediate portion of the trunnion 51
There are slight gaps c 1 and c 2 between the roller 11 c and the trunnion 51 disposed between the b and the trunnion 51 and between the roller 11 c and the trunnion 51. When transmitting the rotation torque from one rotation shaft to the other rotation shaft, the deflection amount increases at the tip end of the trunnion 51. However, the base end roller 11a, the intermediate portion roller 11b, and the tip end roller 11c. Since the diameters of the trunnions 51 are different from those of the trunnions 51, the gaps between the rollers 11a, 11b, 11c and the trunnions 51 are made to gradually increase at the tip end side, as shown in FIG. Contact according to the amount of bending. Even if a load is applied to the trunnion 51 during transmission of the rotational torque in this way, the gap between the rollers 11a, 11b, 11c and the trunnion 51 is a gap corresponding to the amount of bending, so that the rollers 11a, 11b, 11c Means that a uniform load is applied.

Workability is improved. In addition, since a complicated process of imprinting a stamp on each of a large number of rollers is not required, man-hours can be reduced. Further, the load applied to each roller of the trunnion and the bearing during transmission of the rotational torque becomes uniform, so that the life of the bearing is prolonged.
