Problems solved by technology

From the point of view of strength and deformation, these open structures have great disadvantages, since the components are thus subjected to high additional stresses
Also, these structures have too many parts because the functions of these parts are different from load transfer

Embodiment Construction

[0020] The present invention will be further described below in conjunction with specific examples.

[0021] Such as figure 1 and figure 2 As shown, the improved structure of the compact wind power generating set described in this embodiment includes at least one rotor blade (not shown in the figure), hub 1, gearbox 2, generator 3, drive train casing 4, yaw Component 5 and engine room seat 7 with built-in hydraulic pressure, lubrication and integrated cooling system 6. The hub 1 is equipped with a pitch bearing 19. The pitch system is the same as that of a traditional wind power generating set. It adopts an electric pitch system with internal gear meshing transmission, and is driven by a pitch motor through a pitch gearbox. The outer wall of the wheel hub 1 and its components can withstand wind, sun and rain without fairing. The rotor blades are connected to the hub 1 through pitch bearings 19 . The hub 1 is bolted to the inner ring of the rotor bearing 11 of the gear box...

Abstract

The invention discloses an improved structure of a compact type wind power generating set. The improved structure comprises at least one rotor blade, a hub, a gear case, a generator, a transmission system shell, a yawing assembly and a cabin base. The rotor blades are connected with the hub through a variable pitch bearing. The hub is connected to an inner ring of a rotor bearing of the gear case through a wind wheel lock disc, a front end cover of the gear case and a bolt. A front end flange and the rotor bearing of the gear case and the transmission system shell are arranged between the hub and the cabin base, designed into load transmission components and connected through flange bolts. The gear case and the generator are arranged in the transmission system shell. The transmission system shell is connected to the cabin base through bolts. The cabin base is connected with a tower through yawing bearings of the yawing assembly, and he tower is matched with the wind power generating set. The improved structure is very compact, light and low in cost.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to an improved structure of a compact wind power generating set. Background technique [0002] It is well known in the industry that with the continuous development of wind power generation technology, the capacity of a single unit of wind power generators continues to increase, and their dimensions also continue to increase, making their production, transportation and installation costs higher and higher. In the structural design of new wind turbines, the trend is to use more compact and lighter units. In the traditional wind turbine structure, the gearbox and the generator are arranged behind the bearings as independent components on the main frame, so the main frame has the function of transferring the rotor load from the rotor bearing to the tower, and the load on the bearing is It must be introduced into the tower from the bearing bolting surface via the main fra...
