Abstract
A wind-generation speeding transmission is provided, which comprises a box body, a speeding transmission mechanism composed of a grade-1 compound planetary gear train and a grade-1 ordinary gear transmission. The input shaft of the speeding transmission mechanism is joggled with a planetary gear via an inner gear loop connected and joggled with the sun gear via a big planetary gear. The sun gear is connected with end driving gear. After the power is speeded via end ordinary gear, it will be outputted through high-speed output gear linked with output coupling. The input gear is connected with the main gear of the wind generator through an expansion sleeve. The sun gear is connected with the end driving gear via a spline. The input gear adopts the packing contact-type sealing, while the high-speed gear adopts labyrinth-type of non-contact sealing. The box body of the utility model is composed of a front box body, a middle box body, and a rear box body. On the front box body is provided with two gear holes that match the elastic post pin supported on the machine chamber. In addition, the utility model has the advantages of reasonable structure, compact and convenient in use, long service life, better integration performance and reliability, lucid outline and nice outlook, etc.
