エンド品と述べる）１０とが公知である。 Conventionally, in order to install industrial machinery that generates unbalanced force due to rotational motion, reciprocating motion, etc. on the floor,
As a method for supporting the frame of a mechanical device with a plurality of vibration isolators, a rubber-covered coil spring that also has a damper effect is formed from a metal wire 1' with a circular cross section to an equal coil pitch P, as shown in Fig. 1. With respect to the compression coil spring 1, there is provided a thick spiral tubular rubber member 2 whose longitudinal cross-sectional shape becomes a root 3 of the outer thread at each metal wire portion and an arcuate peak 4 at the center between the pitches of the metal wire. A bellows-shaped rubber-coated coil spring of the open-end spring type on both sides (hereinafter simply referred to as an open-end product) 5 or a coil pitch P from a metal wire 11' of wire diameter d as shown in FIG. A molded compression coil spring is attached, and the pitch of the final turn on both end faces of the coil spring is P 0 =
d, the vertical cross-sectional shape of the final turn of the metal wire is shaved off so that it becomes a half-moon shape in which the missing portion 15 becomes larger in the distal direction, and the end surface of the coil is in contact with the plane over the entire circumference for the both-end closed-end spring 11. , the longitudinal cross-sectional shape is the root 1 of the outer thread at each metal wire part.
3, a bellows-shaped rubber-coated coil spring (hereinafter simply referred to as both ends) is a double-end closed-end type spring formed by attaching a thick spiral tubular rubber member 12 that forms an arc-shaped peak 14 at the center between the pitches of the metal wire. 10 (referred to as closed-end products) are publicly known.

いる。 However, in the conventional type, for example, in the open-end product 5 shown in FIG. 1, the coil spring is open-ended at both ends, so the elastic modulus is microscopically different in the annular portion that becomes the pressure-receiving portion of the support surface at both ends. When sitting is difficult and a compressive load is applied, the load distribution acts in a direction that promotes buckling of the rubber member. Therefore, when the open-end product 5 is subjected to shear force under a steady compressive load,
In the shear-deflection diagram, the shear deflection characteristic is such that it deflects greatly even when subjected to a small shear force.
As a result, it has the disadvantage of causing lateral sway on the pedestal side.

る。 In order to suppress lateral shaking, a double-end closed-end product 10 shown in FIG. In the closed-end product 10, there is no inner thread of the rubber member at both ends in the axial direction. That is, in the manufacturing method of the double-end closed-end product 10, if the core mold for forming the inner thread is integrated, the core mold cannot be taken out, and the product must be divided into parts. However, this split type core mold has a technically very complex structure, and has the disadvantage that it requires a lot of labor and time to assemble and disassemble the mold, especially during the vulcanization process, which increases costs. .

Since the core mold can be removed by turning the screw, manufacturing is easy and the cost can be reduced, but as mentioned above, it has the drawback of causing lateral wobbling. That is, both the open-end product 5 and the both-end closed-end product 10 have advantages and disadvantages.

品と述べる）を提供する。 The present invention was devised in view of such problems, and aims to solve the disadvantages of the two conventional examples. When a molded compression coil spring is placed, the vertical cross-sectional shape of the coil spring in the unloaded state becomes the bottom of the outer thread at each metal wire portion, and an arc shape at the center between the pitches of the metal wire. In a bellows-shaped rubber-coated coil spring made of a thick spiral tubular rubber member that forms a crest, both axial ends thereof have a plane perpendicular to the axial direction, and the coil spring has a pressure-receiving end surface. With one side of the final turn as pitch P 0 = d, cut off the last turn of the metal wire so that the vertical cross section has a half-moon shape in which the missing part gradually increases toward the end, so that the end face of the coil spring is completely covered. A bellows-shaped rubber-coated coil characterized in that one side of the coil has a closed end that contacts a flat surface over the circumference, and the inner shape of the rubber member at the closed end portion is a cylindrical inner circumferential surface having the same diameter as the inner diameter of the rubber-coated spring or a small diameter. We provide springs (hereinafter simply referred to as single-ended closed-end products).

A compression coil spring 21 with a pitch P (14 mm) and an average coil diameter D (37 mmφ) is made from a spring steel 21', with one side that will become the pressure receiving end face being the pitch P 0 = d of the final turn, and the final turn of the metal wire. The cross-sectional shape is shaved off so that it becomes a half-moon shape 25 in which the missing portion gradually increases toward the distal end, and the end surface of the coil spring is made into a one-sided closed end in contact with a plane over the entire circumference, and compared to the one-sided closed-end compression coil spring 21. Then, when a thick spiral tubular rubber member 22 is attached, the longitudinal surface shape becomes a valley 23 of the outer thread at each metal wire portion and an arcuate peak 24 at the center between the pitches of the metal wire. This is the closed-end product 20. The method of attachment is to attach a coil spring 21 with a closed end on one side and a cylindrical coil spring 21 to an outer mold that is divided into upper and lower halves and an integrated core mold that form the outer thread of the one end closed end product 20. The unvulcanized rubber member may be placed concentrically and vulcanized and bonded.

可能である。 Regarding the shape of the core mold, one end in the axial direction has the outer peripheral thread cut up to form the inner thread of the one-end closed-end product, and the other end has the one-end closed-end product. It is necessary to form a cylindrical shape having the same diameter or a smaller diameter than the inner diameter of the one-end closed-end product 20 that forms the inner surface of the closed-end portion of the coil spring 21. With the above shape, the one-end closed end product 20 forms an internal thread,
The shape of the rubber member of the closed end part has a cylindrical inner peripheral surface with the same diameter or smaller diameter as the inner diameter of the rubber covered spring, and after vulcanization molding, if this core mold is turned in the direction in which the screw comes out, , it is possible to take out the core mold from the inner threaded part of the one-sided closed-end product 20.

As shown in FIG. 5, an upper tray 31 having a cylindrical convex portion 31' approximately equal to the inner diameter of the one-end closed-end product 20 is fixed to the lower surface 30' of the pedestal 30 of the mechanical device. The hollow part on the open end side of the one-end closed-end product 20 is inserted into the cylindrical protrusion 31', and the cylindrical protrusion is inserted into the hollow part on the closed-end side of the one-end closed-end product 20 on the floor 33 side. A lower tray 32 having a diameter of 32' is provided, and an anchor bolt 3 is attached to the floor 33.

る程度のせん断ばね特性である。 Next, the operation of the device of the present invention will be explained. By making one side of the coil spring 21 a closed end, the closed end side has a better sitting position, which has the effect of preventing the buckling of the rubber member, and when a vertical steady load is applied, the force caused by one end being open is reduced. Due to the dispersion of
In addition to producing the effect of alleviating the shear force generated in
For example, the shear deflection characteristic of the one-end closed-end product 20 with a load sharing ratio of 7 to 3 between the rubber member and the coil spring under a steady vertical load is A, and the shear deflection characteristic of a similar open-end product is B.
In this way, the one-end closed-end product 20 has high shear spring characteristics that make it extremely difficult to bend even when subjected to the same shear force. Further, the shear deflection characteristic of a similar double-end closed-end product is C, and the single-end closed-end product 20 has slightly inferior shear spring characteristics compared to the double-end closed-end product.

より実用価値は大なるものである。 As mentioned above, the shear deflection characteristics can be significantly improved compared to open-end products, so
The one-end closed-end product 20 of the present invention has no difference in manufacturing method from the open-end product 5, so it can be manufactured at low cost. For the above reasons, it has great practical value.
