| description | The invention discloses a variable pitch driving system which is used for a wind generating set. The variable pitch driving system comprises a motor and a reducer which is connected with an output shaft of the motor, wherein the reducer comprises a planet gear transmission system which is connected with the output shaft of the motor and has multistage transmission, and the output end of the planet gear transmission system is fixedly connected with blades of the wind generating set. The closed type gear transmission is adopted in the variable pitch driving system, when the planet gear transmission system is operated, the number of meshed gears is increased, stress of the meshed gears is improved, reliability of the variable pitch driving system is improved, and the service life of the variable pitch driving system is prolonged. In addition, the planet gear transmission system is adopted in the variable pitch driving system, a variable pitch bearing is removed, and the structure of the variable pitch driving system is more compact. |
