Abstract
The invention discloses a yawing supporting structure of a wind generating set. The yawing supporting structure is characterized by comprising a hollow supporting cylinder body, a machine frame connecting flange is arranged at the position of an opening in one end of the supporting cylinder body, a tower cylinder connecting flange is arranged at the position of an opening in the other end of the supporting cylinder body, a yawing driving mounting hole and a lubricating gear mounting hole are formed in the inner wall of the supporting cylinder body, the supporting cylinder body, the machine frame connecting flange and the tower cylinder connecting flange are formed by integrally casting spheroidal graphite cast iron, and the percentage composition of silicon of the spheroidal graphite cast iron is below 25%. The yawing supporting structure is the hollow supporting cylinder body, and on one hand, the hollow supporting cylinder can be separately transported, the transportation difficulty can be reduced, transportation is convenient, the transportation cost is low, and mounting is convenient; on the other hand, a machine frame is connected with a tower cylinder through a casting, vibration generated by one part of the machine frame can be absorbed, and the running stability of the wind generating set is improved.
Description
[technical field]
The present invention relates to a kind of driftage supporting structure of wind power generating set.
[background technique]
Along with the raising of wind power generating set power, more and more higher to the requirement of driftage supporting structure.The increase of driftage driving structure size, the raising of yaw system load, all can increase the size of driftage supporting structure, installs to transportation and causes certain difficulty.
[summary of the invention]
The object of the invention is to overcome the deficiencies in the prior art part, provide a kind of easy for installation, convenient transportation, cost of transportation is low, improves the driftage supporting structure of the wind power generating set of the stability of unit operation.
The object of the present invention is achieved like this:
A kind of driftage supporting structure of wind power generating set, it is characterized in that the support cylindrical shell that it comprises hollow, one end opening of described support cylindrical shell is provided with frame adpting flange, the other end opening of described support cylindrical shell is provided with tower cylinder adpting flange, and described support cylinder inboard wall is also provided with driftage drive installation hole.
The driftage supporting structure of a kind of wind power generating set as above, is characterized in that described support cylinder inboard wall is also provided with oilgear mounting hole.
The driftage supporting structure of a kind of wind power generating set as above, is characterized in that described support cylindrical shell and frame adpting flange and tower cylinder adpting flange adopt spheroidal graphite cast iron integrally casting to form.
The driftage supporting structure of a kind of wind power generating set as above, is characterized in that the element silicon percentage composition of described spheroidal graphite cast iron is below 25%.
The driftage supporting structure of a kind of wind power generating set as above, is characterized in that described supporting drum surface is provided with anticorrosive coat.
The driftage supporting structure of a kind of wind power generating set as above, is characterized in that described support cylinder inboard wall is provided with mounting part, and described driftage drive installation hole and oilgear mounting hole are arranged on mounting part.
