Description
Technical field
The present invention relates in wind power generating set the gear ring used.
Background technology
In the working process of wind power generating set, each component of unit subject the effect of the load such as aerodynamic force, mass force load, gravity loading and operation load, the feature of these load can be static, dynamic, circulation, moment, impact, random, and wind speed and direction is constantly change, in order to tackle the continuous change of wind speed and direction, wind power generating set is made to export constant power. Need to shorten assembly servicing time, reduce maintenance cost, to increase work efficiency.
Summary of the invention
The present invention provides the gear ring used in a kind of wind power generating set, it is intended to shorten the time keeped in repair of carrying out because of component wear, reduces maintenance cost, it is to increase working efficiency, solves after the change because of wind speed and direction makes gear wear, changes the huge cost that gear brings. Like this when after a certain lobe serious wear of gear, it is possible to point lobe is changed, thus solve replacing construction length and the many problem of cost.
In order to achieve the above object, the present invention improves the constructional feature being that Yaw system gear ring divides lobe and is arranged on seat ring. Specifically, a kind of Yaw system gear ring of the present invention, comprises the disc-shaped base that central authorities arrange circular hole; The excircle of described base upwards forms collar flange, and described flange upper surface circumference is positioned at middle part and forms positioning boss; The circular arc shape gear ring that six outer cambered surfaces arrange teeth is seated on described flange with the connecting method of a full circumferences, and the locating slot of described gear ring lower surface is stuck on described boss; The open holes of heavy head form is offered at vertical interval, the upper surface of described gear ring, offer the bolt hole of heavy head form corresponding to vertical interval, described boss upper surface, wear hexagon bolt by described open holes and bolt hole and described gear ring is fixed on base by nut; In addition, on each lobe gear ring, interval is vertical arranges two erection opening.
Under optimal way, described hexagon bolt 4 is by wearing in described open holes after a compression spring.
The present invention substantially increases the work-ing life of wind power generation yaw system gear ring and well saves production cost.Its economic benefit is surprising, and this invention is simple and practical, well solves short problem in Yaw system gear ring work-ing life.
Accompanying drawing explanation
Fig. 1 is the projection structure schematic diagram of Yaw system gear ring of the present invention;
Structural representation is partly cutd open in the side-looking that Fig. 2 is Yaw system gear ring shown in Fig. 1.
Embodiment
Yaw system gear ring of the present invention as illustrated in fig. 1 and 2, comprises the disc-shaped base 1 that central authorities arrange circular hole. The excircle of base 1 upwards forms collar flange, and flange upper surface circumference is positioned at middle part and forms positioning boss. Six circular arc shape gear rings 2 are seated on described flange with the connecting method of a full circumferences, and the locating slot of described gear ring 2 lower surface is stuck on described boss. Heavy hair style open holes 5 has been offered at the vertical interval, upper surface of described gear ring 2, corresponding, the bolt hole of heavy head form is offered at vertical interval, described boss upper surface, wears hexagon bolt 4 by described open holes 5 and bolt hole and described gear ring 2 is fixed on base 1 by nut; In addition, on each lobe gear ring 2, interval is vertical arranges two erection opening 6. Under optimal way, described hexagon bolt 4 is interior hexagon bolt, and by being arranged in described open holes 5 after a compression spring.
In Fig. 1, the radian of each lobe gear ring is 60 degree, and there are 16 teeth the outside of each gear ring. And the radian between two erection opening 6 of each lobe gear ring is 28 degree, corresponding each erection opening 6 is 16 degree apart from the radian at gear ring two ends. And between adjacent two lobe gear rings, leave the gap of 5 millimeters. As shown in Figure 2, in addition the flange inner of yaw system base 1 and base circle is excessively that the circular arc of radius 30 millimeters is excessive.
In the working process of wind power generating set, each component of unit subject the effect of the load such as aerodynamic force, mass force load, gravity loading and operation load, the feature of these load can be static, dynamic, circulation, moment, impact, random, and wind speed and direction is constantly change, in order to tackle the continuous change of wind speed and direction, wind power generating set is made to export constant power. Shorten the time carrying out because of component wear keeping in repair, reduce maintenance cost, it is to increase working efficiency. After Yaw system gear ring is cut into six lobes, then six lobes are assembled into one, can solve after the change because of wind speed and direction makes gear wear like this, change the huge cost that gear brings. Like this when after a certain lobe serious wear of gear, it is possible to point lobe is changed, thus solve replacing construction length and the many problem of cost.
The above; it is only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; any it is familiar with those skilled in the art in the technical scope of present disclosure; technical scheme and invention design thereof according to the present invention are equal to replacement or are changed, and all should be encompassed within protection scope of the present invention.
