Problems solved by technology

[0009] Since there is no main shaft, the main bearing is integrated into the gearbox, and the hub of the impeller is directly connected to the input shaft of the gearbox, which causes the gearbox to directly bear the wind load, and the load of the gearbox increases greatly, and the strength and rigidity of the structure are required very high. Make the design of the gearbox more difficult, the weight increases, and the manufacturing difficulty also increases
Moreover, during the operation of the wind turbine, due to the wind load, the gears will be greatly deformed, which will affect the meshing of the gears and easily cause failures.
If the gearbox fails and cannot be disassembled for maintenance separately, the gearbox must be disassembled after the hub is disassembled, which also affects the maintenance performance of the wind turbine

Embodiment Construction

[0042] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0043] Such as figure 1 As shown, the transmission chain of the wind power generating set in this embodiment mainly includes an impeller, a main shaft 3 , a main bearing 4 , a gearbox 5 , a generator 6 and a coupling 7 .

[0044] The impeller includes a hub 2 and one or more blades 1 arranged on the hub 2 . The main bearing 4 is installed on the main frame 9 of the wind power generating set, and the main shaft 3 is supported on the main bearing 4 . Wherein, the main bearing 4 may adopt a double-row back-to-back tapered roller bearing in the prior art, or two independent bearings, and its specific implementation method is not limited here. The gear box 5 includes a box body 511 , a gear trans...

Abstract

The invention provides a transmission chain of a wind generating set and the wind generating set. The transmission chain of the wind generating set comprises an impeller, a speed increasing box (5), a generator (6) and a coupling (7). The impeller comprises a hub (2) and blades (1) arranged on the hub (2). The speed increasing box (5) comprises an input shaft (501) and an output shaft (510), and the input shaft (501) rotates under driving of the hub (2). The generator (6) comprises a generator stator (601) and a generator rotor (602) arranged in the generator stator (601). The coupling (7) is arranged in the generator rotor (602), and the output shaft (510) of the speed increasing box (5) is connected with the generator rotor (602) through the coupling (7). The transmission chain of the wind generating set achieves the technical effect of overall compact arrangement with the coupling arranged.

Description

technical field [0001] The present invention relates to the field of wind power generation, and more specifically, to a transmission chain of a wind power generator set and a wind power generator set. Background technique [0002] With the rapid development of the wind power industry at home and abroad, the technology of wind power generators continues to develop, and the technical requirements for wind power generators are getting higher and higher. As the core part of wind power The research and development focus of the unit. The wind power generating set mainly includes the main frame and the transmission chain of the wind power generating set supported on the main frame. The main frame is used for installing the main shaft and plays a load bearing role. A wind turbine transmission chain generally includes an impeller with blades and a hub, a gearbox, a generator, a coupling, and the like. [0003] In order to reduce the length of the transmission chain of the wind powe...
