A kind of wind power generating set supports with the generator vibration damping, and described vibration damping is supported for assembled structure, has the metallic base of taper type and the upper support seat of taper type; Described upper support seat is a cavity structure, in the conical cavity between metallic base and upper support seat intermediate elastomeric is set; Described upper support seat has the boss of band circular cavity, the cone shape hole that has a connectivity in the lower end of boss cavity; On metallic base, has tapped hole; Metallic base and upper support seat are connected as a single entity through clamping bolt; Wherein, The screw thread of clamping bolt lower end cooperates with tapped hole on the metallic base; The conical surface of upper end is fitted on the cone shape hole of upper support seat, and is provided with the cone rubber pad between the hole wall of the conical surface on clamping bolt and upper support seat cone shape hole, constitutes the structure of can regulate vibration damping support stiffness; The internal face of the circular cavity that the upper support seat is had has and is used for and heightens the screw thread that bolt thread cooperates; Described upper support seat with heighten bolt thread and cooperate, but constitute the structure that height that in the vertical direction supports vibration damping is adjusted; The said center of heightening bolt has tapped hole, in order to be connected with generator through connecting bolt.
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.
Because adopt aforesaid technological scheme, the utility model 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 using process 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 fixing bolt that different torque changes product each to stiffness characteristics.
4. the component 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, petroleum productions except that the wind-powered electricity generation field in addition.
