Described intermediate elastomeric is made up of the two-layer above cone-shaped metal spare and the vulcanization of rubber more than one deck together; Have inside and outside two conical surfaces; Wherein the male cone (strobilus masculinus) of intermediate elastomeric cooperates with the inner conical surface of upper support seat, and the inner conical surface of intermediate elastomeric cooperates with the male cone (strobilus masculinus) of metab.
The top of said fastening bolt is the inversed taper platform structure, and the bottom is for having externally threaded cylindrical structural.
On the upper surface of fastening bolt, have two or more circles or square counterbore.
Because adopt aforesaid technical scheme, the present invention produces following good effect:
1, above-mentioned generator vibration damping supports except basic safety supports function can be provided, suitable vertical, horizontal rigidity can also be provided, and has satisfied the double requirements of support, vibration damping.
2, above-mentioned generator vibration damping be supported on that product is installed and use in can heighten being threaded into of bolt through adjusting and regulate the product whole height highly very easily, thereby satisfy the altimetric compensation requirement between the generator shaft and gearbox output shaft in the generator installation process.
3, each parts of supporting of above-mentioned generator damping are split-type structural, and can through apply on set bolt that different torque changes product each to stiffness characteristics.
4. the parts that above-mentioned generator damping is supported are less, and processing and easy to assembly is applicable to producing in batches and the scale use; The product structure of this kind form also can be applied to the vibration and noise reducing engineering like fields such as boats and ships, oil exploitations except that the wind-powered electricity generation field in addition.
