Abstract
The utility model provides a connecting structure of a wind wheel main shaft and a generator shaft of a small and medium size wind driven generator. The connecting structure includes a wind wheel, a main shaft and a generator, wherein the wind wheel is rigidly connected with the main shaft, the output terminal of the main shaft is connected with a main shaft connection shaft sleeve, a shaft of the generator is connected with a generator shaft sleeve, the main shaft connection shaft sleeve and the generator sleeve are connected by a double telescopic universal joint, the double telescopic universal joint is composed of a front single universal joint and a rear single universal joint which are connected by a spline shaft and a spline sleeve. According to the connecting structure, a self-aligning roller bearing used in the structure plays a role of adjusting the center of the wind wheel main shaft, the function of the double telescopic universal joint is to make the angles of the output terminal of the wind wheel main shaft and the input terminal of the generator shaft be equal, thus the instantaneous angular velocities of the shafts are same and stable operation with an equal velocity is achieved.
Description
Technical field
The utility model relates to wind turbine equipment field, especially a kind of middle-size and small-size wind turbines rotor main shaft and generator shaft syndeton.
Background technology
Present middle-size and small-size wind turbines rotor main shaft and generator shaft connected mode are divided into direct-coupling; Or the wind wheel main shaft separates with generator shaft, connect or the mode such as single universal joint connection by spring coupling, the instantaneous angular velocity that this connected mode exists between wind wheel main shaft and generating axle mostly is unequal, easily Caused Vibration, the damage of aggravation parts, and produce very large noise.
The utility model content
The purpose of this utility model is to provide a kind of stable, middle-size and small-size wind turbines rotor main shaft and generator shaft syndeton that noise is little for the deficiency that solves above-mentioned technology.
In order to achieve the above object, middle-size and small-size wind turbines rotor main shaft and generator shaft syndeton that the utility model is designed, it mainly comprises wind wheel, main shaft and generator, wind wheel and main shaft are rigidly connected, the output of main shaft is connected with the main shaft connecting bushing, be connected with the generator axle sleeve on generator shaft, the main shaft connecting bushing is connected by duplex concertina type universal joint with the generator axle sleeve.
Described duplex concertina type universal joint is comprised of former and later two single universal joints, is connected with spline housing by splined shaft between two single universal joints.
As optimization, be provided with side by side two deep groove ball bearings at the input of main shaft, the output of main shaft is provided with self-aligning roller bearing.
The resulting middle-size and small-size wind turbines rotor main shaft of the utility model and generator shaft syndeton, its self-aligning roller bearing that adopts plays the effect of adjusting the wind wheel alignment of shafts, the effect of duplex concertina type universal joint makes wind wheel main shaft output equate with the angle of generator shaft input, and guarantee that the diaxon instantaneous angular velocity equates all the time, realizes uniform velocity stable operation.
