必要強度を付与していたが、これでは成形材料が
多く必要となる欠点があり、しかも十分な強度を
とることがむずかしかつた。 Conventionally, the wall thickness of the boss portion was increased to provide the necessary strength to this portion, but this had the disadvantage that a large amount of molding material was required, and moreover, it was difficult to obtain sufficient strength.
また上記軸受装置は十分な軸封機能を必要とす
る。 Further, the above-mentioned bearing device requires a sufficient shaft sealing function.
本考案は上記のことにかんがみてなされたもの

提供しようとするものである。 The present invention was developed in view of the above-mentioned problems, and it is possible to support a water pump case made of plastic even with a relatively thin wall thickness, and to reduce the processing required for the case. Another object of the present invention is to provide a bearing device having a sufficient shaft sealing function.

なつている。 The auxiliary cylinder 9 is made of substantially the same material as the outer cylinder 8, for example, a steel pipe, and is integrally fixed to the boss portion 2a by being embedded therein. Further, this auxiliary cylinder 9 extends over the entire length of the boss portion 2a in the axial direction, and therefore has a length that surrounds the outer cylinder 8 and the mechanical seal 10.

図ることができる。 As described above, the bearing device according to the present invention includes a drive shaft 4 of a water pump 1 to which an impeller 5 is fixed to one end.
an outer cylinder 8 made of a high-strength material that supports the outer cylinder 8 via a rolling member; an auxiliary cylinder 9 made of a high-strength material that fits and supports the outer cylinder 8 and is longer than the outer cylinder 8; A mechanical seal 10 is interposed between the impeller 5, a rotary ring 13 is fixed to the drive shaft 4 in a liquid-tight manner, and a fixed ring 12 is fitted to the inner surface of the auxiliary cylinder 9 in a liquid-tight manner. Since the auxiliary cylinder 9 is embedded and fixed to the boss portion 2a of the case 2 of the water pump 1 made of a low-strength material over its entire length, the load acting on the outer cylinder 8 from the drive shaft 4 is as follows. It is directly supported by the auxiliary cylinder 9 made of high-strength material, and is not directly applied to the boss 2a of the case 2, but is applied to the inner peripheral surface of the boss 2a of the case 2 through the entire outer peripheral surface of the auxiliary cylinder 9. Although the case 2 is made of a material with low strength such as plastic or aluminum alloy, it has sufficient strength and the wall thickness of the boss portion 2a is relatively small. It can be made thinner, the amount of molding material can be reduced, and material costs can be reduced.

る。 Furthermore, according to the present invention, even if a large force acts on the impeller 5 and, by extension, the drive shaft 4 and the drive shaft 4 moves relative to the case 2, the drive shaft 4 and the auxiliary cylinder 9 are integrally formed. The rotary ring 13 and stationary ring 12 of the mechanical seal 10 attached to the drive shaft 4 and the auxiliary cylinder 9 also move integrally, so that the sliding surfaces of the two wheels 13 and 12 are always maintained in a normal state. Therefore, the surface pressure on the sliding surface of the mechanical seal 10 is stabilized regardless of changes in the force acting on the drive shaft 4, and good sealing performance can be obtained.
