Abstract
The utility model discloses a hub structure for a wind generator set, which pertains to the technical field of wind generator sets. Apparently, the hub structure is in an integral hollow spherical structure, and two corresponding ends of the outer spherical surface thereof are respectively a spindle connecting end surface and a guiding cover support mounting end surface; the outer spherical surface between the spindle connecting end surface and the guiding cover support mounting end surface is peripherally and uniformly provided with three vane mounting holes with same structure; the end surface of each vane mounting hole is a bearing connecting end surface, and is internally provided with a web; each web is provided with a speed reducer mounting base; and a variable-blade control cabinet support is arranged on the inner spherical surface of the hub in each vane mounting hole. The webs are annular plates with elliptical holes, thus achieving the reinforcing effect on one hand, and being capable of supporting variable-paddle speed reducers on the other hand, reducing weight and achieving the optimum stressing effect. The inner sphere center and the outer sphere center of the spherical hub are not superposed, and the outer sphere center inclines to the spindle connecting end surface, thus enabling the weight of the whole hub to be distributed reasonably, and guaranteeing the driving stability.
Description
Technical field
The utility model relates to a kind of wind generator unit wheel hub structure, belongs to the wind-driven generator technical group field.
Background technique
At present, known wind generator unit wheel hub adopts the structure of casting more, realizes being connected of root of blade and main shaft, and the loading transfer that blade is subjected to is to transmission system.But most wind generator unit wheel hubs also will be for other electric elementss etc. provide necessary support and mounting point except that self structure, thereby have influence on the outward appearance and the integrally-built intensity of wheel hub.The rationality and the structural strength thereof that how to guarantee wheel hub structure become the subject matter that will solve.
Summary of the invention
Technical problem at above-mentioned existence, in order to make electric controling element reasonably be arranged in the intensity of wheel hub inside and assurance wheel hub structure, the invention provides a kind of wind generator unit wheel hub structure, this wheel hub not only can make other annexes reasonably be arranged, and can satisfy the structural strength requirement, have outward appearance preferably simultaneously.
Technological scheme of the present invention is as follows:
A kind of wind generator unit wheel hub structure, be the hollow ball shape structure on its overall appearance, its outer spherical surface opposite ends is respectively main shaft and connects end face and air guide sleeve support installation end face, on the outer spherical surface between main shaft connection end face and air guide sleeve support installation end face, evenly be provided with 3 blade installation holes that structure is identical along circumference, each blade installation hole end surface is bearing and connects end face, be equipped with web in it, be equipped with the speed reducer fitting seat on the web, be equipped with the pitch control cabinet bearing on the wheel hub inner ball surface in each blade installation hole.
Described web is an annular slab, has a plurality of bolt auxiliary holes that are connected with change blade sheet along its circumference.Described inside and outside spherical surface is an eccentric structure, and the outer spherical surface centre of sphere is partial to main shaft and is connected end face.
The invention has the beneficial effects as follows:
The present invention adopts the casting material of EN-GJS-350-22U-LT as wheel hub, and this material can satisfy the requirement on structure and the weight simultaneously.With the blade installation hole of pitch variable bearings joint in web is set, can play reinforing function on the one hand, can provide support for variable pitch speed reducer on the other hand.In order not increase the overall weight of wheel hub, web is the annular slab that has ellipse hole, has promptly reduced weight and has reached best stressed effect again.Offer a plurality of bolt installing technological holes that are connected with change blade sheet in web edge, make things convenient for the placement and the installation of wheel hub and blade connecting bolt.
The present invention adopts spherical structure, makes wheel hub have splendid outward appearance, and has fabulous dynamic property.The centre of sphere and the outer centre of sphere do not overlap simultaneously, and the outer centre of sphere is partial to main shaft and is connected end face, and the weight of whole wheel hub is reasonably distributed, and makes force structure more reasonable, guarantees stability of transmission.The present invention is cast as one with pitch control cabinet bearing and wheel hub, improves the Security of structure, and saves the space.The present invention makes it have better outward appearance and transmission performance on the basis of satisfying wind generator unit wheel hub weight and structural strength.
