Description

[Detailed Description of the Invention] (1) Technical Field of the Invention The present invention relates to a dish-shaped spring mounting structure that is easy to handle and mount, and is used for intervening and pressing a device made of a soft material.

(2) Conventional technology and problems Disc springs generally have a large load capacity despite a small amount of displacement (compression), so they are widely used as buffer members, preload members, etc. in advanced equipment. .

Conventionally, in most cases, the structure for mounting the disc spring at these locations was directly interposed between the constituent members, and therefore, a careful structure was required to prevent positional deviation between planes. Otherwise, for example, if a cylindrical communication device is housed in a cylindrical pressure-resistant case and the device is supported in the axial direction by interposing a disk spring between both end face plates of the case, the disk spring is There is the disadvantage that the power and signal cables that move in the radial direction and pass through the disk spring may be damaged at the edges of the disk spring. It becomes even more troublesome when a plurality of disk springs are mounted at a plurality of locations or in series. Furthermore, if the mating surface is made of a softer material than the material of the disc spring, this surface will be damaged.

(3) Purpose of the invention In view of the above-mentioned conventional problems, the purpose of the invention is to provide a disk-shaped spring mounting structure that is easy to handle and mount, and is press-fitted into equipment made of soft materials. It is.

(4) Structure of the invention In order to achieve the above object, the main structure of the invention is to provide a dish-shaped spring assembly for press-supporting a device, which includes a dish-shaped spring and a dish-shaped spring assembly. It consists of a first annular receiving fitting having a recessed part on the inside and a second annular receiving fitting having a stepped part on the inside, which abut on both surfaces in the axial direction, and the outer diameter of the disk-shaped spring is equal to the inner diameter of the recess of the first receiving fitting. and the inner diameter of the disc-shaped spring forms a gap with the outer diameter of the stepped portion of the second receiving fitting, respectively, so that the first and second receiving fittings can be moved in the axial direction and in the radial direction. This is a disc-shaped spring mounting structure characterized by being engaged with.

(5) Embodiments of the invention Hereinafter, embodiments of the invention will be specifically described with reference to the drawings.

FIG. 1 is a side sectional view showing one embodiment of a disc-shaped spring mounting structure according to the present invention. In the same figure, it consists of annular first and second receiving fittings 2 and 3 that contact both sides of the disk spring 1 in the axial direction, respectively, and the surface of the first receiving fitting 2 that contacts the disk spring 1 faces inward. It has a recessed part 4, and the second receiving metal fitting 3 has a stepped part on the inside.

An appropriate gap is formed between the outer diameter of the disc spring 1 and the inner diameter of the recess of the receiving metal fitting 2, and the inner diameter of the disc spring 1 and the outer diameter of the stepped portion 5 of the receiving metal fitting 3 are An appropriate gap is formed between them. A plurality of holes 6 (two holes in the figure) are formed on the surface of the receiving metal fitting 2, into which a guide pin 7 protruding from the receiving metal fitting 3 in the axial direction is movably fitted. The head of the guide pin 7 is formed on the protruding side of the guide pin 7, and the guide pin 7 is constructed so as not to be separated from each other as an assembly.

In the state shown in FIG. 1 above, the disc spring 1 is not deformed, that is, no pressure is applied, and a gap is provided between the receiving fittings 2 and 3 in the axial direction. Preferably, the surfaces of the receiving metal fittings 2 and 3 in contact with the disc-shaped spring 1 are quench-hardened and polished to make them hard, and preferably coated with a suitable lubricant.

A cylindrical communication device is installed between both end face plates of the cylindrical sealed pressure-resistant case, and the assemblies having the above configuration are pressed together between both end faces of the communication device and the end face of the case. , to intervene in a balanced state. A cylindrical spring is compressed between the outer circumferential surface of the device and the inner circumferential surface of the housing to cushion and support the radial vibration impact, so that the device is suspended in the air so that it can withstand external forces from all directions. Spring supported. Such a configuration is applied, for example, to repeater protection inside a submarine repeater.

When the submarine relay device is transported and installed in the sea, a compressive force acts on one of the receiving metal fittings 2 and 3 in the direction of the arrow, and the disc spring 1 is further compressed in the axial direction. However, the other disk spring expands in the return direction. The compressed disc spring 1 expands in the restoring direction, and the other extended disc spring 1 repeatedly deforms to be compressed, causing a damped vibration and stopping, thereby protecting the equipment. To support. Although the guide pin 7 protrudes during this operation process, a sufficient space is provided in advance so that the guide pin 7 can escape. The disk-shaped spring 1 is prevented from shifting or deviating due to the receiving fittings 2 or 3. Also, due to compression, the outer diameter of the disc spring 1 expands and the inner diameter decreases, but the first
The gap between the inner diameter of the recess of the receiving fitting 2 and the outer diameter of the stepped portion of the second receiving fitting 3 will not cause problems such as digging.

As above, installation between planes,
Having it interposed in the circular part or shaft-shaped part is extremely easy to handle and mount. The receiving metal fitting is hard and its operation is smooth due to the presence of lubricating oil. Even if the end face of the device is made of a soft metal such as aluminum or a soft material such as synthetic resin, by interposing the assembly of the present invention, the effect of the disc spring can be sufficiently obtained.

Different embodiments of the present invention will be explained with side sectional views shown in FIGS. 2 to 5. In FIG. In the figure, the disk-shaped springs 1 are changed in direction alternately, so the deflection of the springs is large.
That is, the former has a large spring constant, and the latter has a small spring constant. Of course, there is no deviation or movement between the springs.

In the embodiment shown in FIG. 4, a guide pin 7' is provided protruding from the outer end surface of the first receiving metal fitting 2', and a hole 6' that fits therein is provided on the outer end surface of the second receiving metal fitting 3'. The operation and effect are the same as in the previous embodiment.

Fig. 5 shows a case in which the cylindrical part of the stepped part 5 of the second receiving metal fitting 3 and the inner circumference of the first receiving metal fitting 2 are fitted without providing a guide pin or hole, and the movement in the axial direction is shown. is free, but movement in the radial direction is prevented by engagement. Therefore, as in the previous embodiment, no radial deflection force acts on the disc spring. Since no guide pin is provided, there is no need to provide a protruding relief portion for the guide pin.

(6) Effects of the invention As described above, the dish-shaped spring mounting structure of the present invention includes the first and second receiving fittings that respectively abut on both sides of the dish-shaped spring in the axial direction. Since it is movable and engages in the radial direction, it can be handled as an assembly, preventing the risk of disc springs shifting or falling as in the past. , synthetic resin, etc., no special protective measures are taken. The gap formed between the receiving metal fitting and the inner and outer diameters of the dish-shaped spring is to accommodate changes in the diameter of the inner and outer diameters due to compression, so the dish-shaped spring will not bite into the receiving metal fitting, or
It won't hurt either. In this way, it is easy to handle and mount and is practical.
