Abstract
The invention relates to a wind turbine generator set generator damping device. A second damping ring is arranged below a first damping ring, first gaskets are fixed both on the upper end face of the first damping ring and the lower end face of the second damping ring, a second gasket is fixed on the lower end face of the first damping ring, a flanging which extends downwards is arranged on an inner circle of the second gasket, a drivepipe is arranged in an inner hole of the first damping ring and the second damping ring, the bottom end portion of the drivepipe is located on the first gasket on the bottom end face of the second damping ring, an mounting bolt is arranged inside the drivepipe in an inserting mode, the first gasket on the bottom end face of the second damping ring is located on a bolt gasket of the mounting bolt, the bolt gasket is located on a bolt head of the mounting bolt, and an external thread section of the mounting bolt penetrates through the first gasket on the top end face of the first damping ring. The wind turbine generator set generator damping device can play a role in well damping, and the noise transmitting to a rack and a tower by a gear case and a generator in the process of the operation of a draught fan is lowered. The wind turbine generator set generator damping device has the advantages of being simple in structure, reliable, convenient to machine, and the like.
Description
Technical field
The present invention relates to a kind of damping device, connect the damping device of usefulness between especially a kind of gear-box, generator and frame that is used for wind-driven generator.
Background technique
Wind-driven generator can produce very big noise when normal operation, this noise part is produced by mechanical motion, and a part is produced by aerodynamic force.Wherein mechanical noise mainly is by the rotating machinery in the cabin, and especially gear-box and generator produce.Gear-box and generator are delivered to the noise on frame and the pylon when reducing fan operation, rubber shock absorber is installed between gear-box, generator and frame is just seemed particularly necessary.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of good damping effect, long service life, generator of wind generating set damping device simple in structure are provided.
According to technological scheme provided by the invention, described generator of wind generating set damping device, below first shock ring, be provided with second shock ring, all be fixed with first packing ring in the upper-end surface of first shock ring and the lower end surface of second shock ring, the interior circle radius of first packing ring is less than the interior circle radius of first shock ring, the interior circle radius of first packing ring is less than the interior circle radius of second shock ring, be fixed with second packing ring in the lower end surface of first shock ring, on the interior circle of second packing ring, be provided with the flange that stretches out downwards, be fixed with the 3rd packing ring in the upper-end surface of second shock ring, on the interior circle of the 3rd packing ring, be provided with the flange that protrudes upward, the interior hole flanging upper end portion of the interior hole flanging underpart of second packing ring and the 3rd packing ring is spaced a distance, in the endoporus of first shock ring and second shock ring, be provided with sleeve pipe, the bottom of sleeve pipe is sitting on first packing ring of the second shock ring bottom end, in sleeve pipe, be fitted with construction bolt, first packing ring of the second shock ring bottom end is sitting on the bolt washer of construction bolt, bolt washer is sitting on the bolt head of construction bolt, and the external thread section of construction bolt passes first packing ring of the first shock ring top end.
The interior circle radius of described first shock ring equates with the interior circle radius of second shock ring.
Distance is 1 ~ 6mm between the interior hole flanging upper end portion of the interior hole flanging underpart of described second packing ring and the 3rd packing ring.
Advantages such as the present invention can play good damping effect, and gear-box and generator are delivered to the noise on frame and the pylon when having reduced fan operation, and it is simple in structure, reliable and easy to process that the present invention has.
