After adopting foretell structure, the leakproofness is very good, can prevent effectively that hydraulic oil from leaking to having ensured the stability of the long -time operation of fan, adapt to bigger single -machine capacity, the cross sectional shape of annular metallic piece is umbrella structure in addition, and it is big to make the side of elastomer bear the area, has improved the impact capacity, has avoided the elastic element's that metal and rubber compounded damage, has further guaranteed life.
Description
Technical field
This utility model relates to a kind of resilient supporting unit, specifically a kind of wind-powered electricity generation resilient supporting unit, belongs to wind motor technical field.
Background technology
Metal and rubber combined flexible member, for many engineering fields, are mainly used for decay vibration and power；Its spring element typically has the rigidity of three-dimensional, i.e. X(is axial), Y(radially), Z-direction (longitudinally) rigidity, this rigidity is predefined by metallic framework, the type of rubber layer, size, tapering and quantity, and is designed to after installing spring element variable in a definite limitation in a suitable case.In the installing and using of wind power generating set, existing structure is mechanical conditioning type gear case elastic support, two toggles for its generating set are supported by resilient support respectively, each toggle is by upper and lower two elastomeric support, elastomer the most all uses precommpression mode, and upper and lower elastomer all has certain pre compressed magnitude.When needs adjust transmission chain rivet system, by screw top on hemispherical jacking block, remake and use rubber elastomer.But, it has been found that the vertical altitude mixture control of this regulative mode is limited, be there is Over-constrained with coordinating of axle sleeve in main shaft.Additionally when elastomer changed by needs, it is difficult to take out upper and lower elastomer in the wind power generating set confined space.
Existing metal is arranged horizontally in rubber bodies with spring in rubber combined flexible member so that performance level analysis is poor, is easily deformed the damage causing metal with rubber combined flexible member, have impact on service life.
Summary of the invention
In order to solve above-mentioned technical problem, the technical problems to be solved in the utility model is to provide one can improve sealing reliability, thus ensures the wind-powered electricity generation resilient supporting unit of blower fan long-play stability.
In order to solve above-mentioned technical problem, wind-powered electricity generation resilient supporting unit of the present utility model, including pedestal and metal-rubber composite elastic element, pedestal and metal-rubber composite elastic element connected by securing member after for supporting toggle, metal-rubber composite elastic element includes rubber bodies and at least one of which annular sheet metal being distributed in rubber bodies, and the cross sectional shape of annular sheet metal is beveled structure；The bottom of metal-rubber composite elastic element arranges the bottom inner chamber of oriented metal-rubber composite elastic element sunken inside, bottom inner chamber is provided with seal membrane, the mounting groove for installing seal membrane it is provided with on pedestal, being mounted with in mounting groove and screw dish for seal membrane sealing compressed, the bottom margin of seal membrane is pressed abd fixed in the mounting groove of pedestal by screwing dish.
The bottom margin of described seal membrane has the outside bulge protruded outside seal membrane and divides and to the projecting inward projecting inward part of seal membrane, it is provided with sunken inside at the medial wall root B of described mounting groove, the described bottom inside screwing dish is provided with inner groove, described projecting inward part coordinates with the sunken inside of mounting groove, and described outside bulge is divided and coordinated with the inner groove screwing dish.
Being provided with positioning convex in described mounting groove, described positioning convex is relative with the end face of the inner groove screwing dish.
After using above-mentioned structure, due to arrange seal membrane and for seal install seal membrane screw dish and mounting groove, after installation, make sealing the best, can effectively prevent hydraulic fluid leak, thus ensured the long playing stability of blower fan, adapt to bigger single-machine capacity, additionally the cross sectional shape of annular sheet metal is beveled structure, the side receiving area making elastomer is big, improve impact capacity, it is to avoid metal and the damage of rubber combined flexible member, further ensure service life.
