Description of the Related Art In a conventional centrifugal casting machine, as shown in FIGS. 2 and 3, for example, a centrifugal casting mold body 1 rotating around an axis moves in and out of the centrifugal casting mold, thereby moving a gutter 2 into a centrifugal casting mold. It is formed to be inserted into and removed from the body 1. This gutter 2 is for supplying molten metal 3 into the inside of the centrifugal casting mold body 1. The centrifugal casting mold body 1 is rotatably supported by a pair of rotation support devices 4 and 5. A flange 6 having a triangular cross section is annularly provided along the circumferential direction at a suitable position on the outer periphery of the centrifugal casting mold body 1. This flange 6 is held between a pair of conical rollers 7.8 arranged in front and behind in the axial direction of the centrifugal casting mold body 1, and a predetermined distance in the axial direction is provided between the roller 7.8 and the flange 6. A gap A is provided. This gap A is for allowing the centrifugal casting mold body 1 to expand in the axial direction. Roller 7.8 is flange 6
The flange 6 is allowed to rotate around the axis of the centrifugal casting mold body 1 by rotating around the axis of the support shaft 9 while in contact with the flange 6 . As a result, the load in the thrust direction of the centrifugal casting mold body 1 is stopped by the rollers 7.8 via the flange 6.

の加重をベアリングケース２７に受は止められている。This gutter 22 is for supplying molten metal 23 into the inside of the centrifugal casting mold body 21. This centrifugal casting mold body 21 is rotatably supported at the circumferential side by a pair of rotation support devices 24 and 25 provided at front and rear positions in the axial direction of the centrifugal casting mold body 21, and re-rotation support is provided. In the devices 24 and 25, the radial load applied by the rotation of the centrifugal casting mold body 21 is received by the bearing case 27 via the bearing 2B. Further, the inner ring 28 of the bearing 26 and the centrifugally cast mold body 22 are fixed by the collar 28 and the bearing nut 30 so that there is no play in the axial direction. In one rotation support device 24, the bearing outer ring 31 and the bearing case 27 are fixed by a bearing case lid 32 so that there is no play. As a result, the centrifugal casting mold body 21 is latched to one of the rotational support devices 24 in the axial direction, and the load in the axial direction is prevented from being received by the bearing case 27.

容される。When pouring the molten metal 23 into the centrifugal casting mold body 21, the gutter 22 is inserted into the centrifugal casting mold body 21 by moving the centrifugal casting mold body 21 in the axial direction while rotating, and the molten metal 23 is poured from the gutter 22. The gutter 22 is pulled out from the centrifugal casting mold 21 by retracting the centrifugal casting mold 21 while pouring the molten metal. During this time, the rotation support devices 24 and 25 stop the bearing case 27 from receiving the radial load applied by the rotation of the centrifugal casting mold body 21 via the bearing 26. Since there is no play between the bearing outer ring 31 and the bearing case 27 in one rotation support device 24, the centrifugal casting mold body 21 is locked in the axial direction, and the load in the axial direction, that is, in the thrust direction, is applied to the bearing case. Uke is stopped by 27. Therefore, there is no need to provide a separate means for receiving load in the thrust direction. In the other rotary support device 25, the gap B allows the centrifugal casting mold body 21 to expand in the axial direction.
