機能を発揮できなかつた。
In the former case, since the synthetic resin is swellable, water impregnates the bearing body 2 and swells, causing the inner surface of the bearing body to wave and change its shape, reducing the bearing clearance, and in the worst case. In this case, the bearing body hugged the shaft and was easily damaged. Therefore, in order to avoid the shape and size of the bearing body caused by this swelling, it is possible to increase the gap between the bearing body or loosen the fit between the bearing body and the bearing housing, but this will reduce the bearing rigidity. The bearing function could not be fully demonstrated.

を用いることはできないし、回転軸の振動が生じ
た時にその振動による衝撃力を緩和できない問題
点があつた。 In the latter case, the pad-shaped bearing is constructed such that the small circumferential gap between the side surface of the pawl and the opposing edge of the pad-shaped bearing is eliminated and radial movement is no longer prevented. Since the movement of the shaft in the circumferential direction is prevented, it is not possible to use a swellable sliding material with good sliding properties, and there is also the problem that when vibration of the rotating shaft occurs, the impact force caused by the vibration cannot be alleviated. It was hot.

軸受を提供することにある。 The purpose of the present invention is to make it possible to release dimensional changes due to swelling of a bearing body made of a swellable sliding material, and to enable movement of the bearing body in the circumferential direction and axial direction even when the bearing body is lubricated. To provide a journal bearing capable of alleviating impact force even when vibration of a rotating shaft occurs.

ある。 FIGS. 1 and 2 show an embodiment of the journal bearing of the present invention. In these figures, a rotating shaft 1 is composed of four pad-shaped bearing bodies 2 installed in a bearing housing 3. It is supported by a bearing. The end surfaces of this pad-shaped bearing body 2 are configured to come into contact with the end surfaces of claws 5 that are integrally constructed with the cover 4 provided at both ends of the bearing housing 4. Further, as shown in the figure, a circumferential gap G 1 and axial gaps G 2 , G 3 are provided, and even if the pad-shaped bearing body 2 swells in size due to swelling, the above-mentioned gaps G 1 , G 3 are provided. 2 and G3 so that they can move freely. Therefore, since no abnormal deformation occurs in the bearing body 2, stable bearing function can be maintained at all times, and reliability is extremely high. Further, even if vibration occurs in the shaft, the bearing body can be deformed within the clearance, so that the impact force applied to the bearing body can be alleviated. Further, in this embodiment, the case where the shaft 1 rotates counterclockwise is shown, but when the shaft 1 rotates clockwise, the pawl 5
The pad-shaped bearing body 2 moves so as to touch the opposite surface of the bearing body, and reversible operation is possible. Further, by moving the cover 5 in the circumferential direction, the position of the pad-shaped bearing body 2 can be easily changed, and assembly and disassembly are also easy. Furthermore, it is economical because it is only necessary to replace the pad-shaped bearing body 2 in which the abnormality has occurred.
