16680号公報でもみられる。 Various vibration isolating devices have been devised in the past, but
In recent years, coil springs have been developed in which a spherical body is fitted into a spherical seat provided in the vibration system, a hanging rod is passed through the center of the spherical body, and a coil spring is interposed between the lower end of the hanging rod and the lower surface of the spherical body. In addition to the spring action of the spherical body and the sliding action between the spherical body and the spherical seat, vibrations can be absorbed by the sliding action between the hanging rod insertion hole provided in the spherical body and the hanging rod. Kosho 56-
This can also be seen in Publication No. 16680.
本考案はこのようなもので、吊棒と球面体の挿

れている。 This will be explained below based on the figures. 1 is an outer tank in which a washing/dehydration tank 3 having rotary blades 2 is installed;
A motor 4 and a bearing case 5 are attached to the outer bottom surface, and the outer tank 1 (vibration system) is suspended from a plurality of hanging rods 7 suspended from the top of the machine frame 6 in a vibration-proof manner. There is.

２間にコイルスプリング１７が介在されている。 A support fitting 9 having a hemispherical spherical seat 8 is fixed to the lower side of the outer tank 1. A spherical body 10 made of an elastic body made of rubber is fitted into the spherical seat 8. A cylindrical portion 11 whose outer diameter decreases as it goes downward from the center of the lower surface of this spherical body 10 is integrally provided vertically. A spring receiver 1 whose upper end abuts the lower surface of the spherical body 10 is provided on the outer periphery of the cylindrical portion 11.
2 are fitted. The hanging rod 7 is passed through insertion holes 13 and 14 provided at the center of the bottom of the spring receiver 12, the cylindrical portion 11, and the center of the spherical body 10.
A washer 15 and a spring receiver washer 16 are fitted to the lower end of the hanging rod 7, and the washer 16 and the spring receiver 1
A coil spring 17 is interposed between the two.

いる。 Therefore, the load of the outer tank 1 is transmitted to the coil spring 17 via the spherical seat 8 and the spherical body 10, and when the coil spring 17 is compressed, the reaction force is transmitted to the spherical body 10 via the spring receiver 12, and the spherical body 10 is compressed.
Since the outer diameter of the cylindrical portion 11 of 0 becomes smaller as it moves downward as described above, a horizontal force is generated in the pressure that the spherical body 10 receives, which causes the inner diameter of the insertion hole 14 to decrease, and the spherical seat 8 The inner diameter of the insertion hole 14 is also reduced by the horizontal component of the reaction force exerted on the spherical body 10, and it comes into strong contact with the suspension rod 7, and as the outer tank vibrates, the insertion hole 14 and the suspension rod 7 are in strong contact with each other. The rod 7 slides, and this sliding contributes to the absorption of vibrations. Of course, the spring action of the spring 17 and the sliding motion between the spherical body 10 and the spherical seat 8 also contribute to the absorption of vibrations.

うにするため吊棒７と接する環状リツプ２０が一
体に突設されている。 A cylindrical body 18 surrounding the hanging rod 7 is integrally protruded from the upper part of the spherical body 10, and the inside of this cylindrical body 18 is filled with grease. In other words, the inside 19 of this cylinder 18 is
It serves as a pocket for storing grease. An annular lip 20 is integrally provided on the upper part of the inner circumferential wall of the cylindrical body 18 to make contact with the hanging rod 7 in order to prevent the grease inside from escaping.
従つて吊棒７と挿通孔１４との摺動部分２１に
はこのポケツト１９よりグリスが常に供給され、
この摺動を円滑にしてこの部分の耐久性を向上さ
せている。 Therefore, the sliding portion 21 between the hanging rod 7 and the insertion hole 14 is constantly supplied with grease from this pocket 19.
This sliding motion is made smoother to improve the durability of this part.

分に自然と供給されて有利である。 As described above, according to the present invention, the cylindrical body 18 that serves as a grease reservoir is integrally provided on the spherical body, and the grease therein is constantly transferred to the sliding part between the hanging rod 7 and the insertion hole 14 of the spherical body. Since the sliding portion is supplied with the sliding portion, it is possible to make the sliding movement smooth, maintain good vibration damping performance, and improve the durability of the sliding portion. Since the grease reservoir is integrally provided on the spherical body, there is no need for any separate parts, which reduces costs.Since the grease reservoir is located at the top, grease is naturally supplied to the sliding parts below, which is advantageous. be.
