Wind generating set

Abstract

The invention relates to a wind generating set, comprising an inner shaft and an outer shaft sleeving the inner shaft; a bearing assembly is arranged between the inner shaft and the outer shaft; the bearing assembly comprises an inner ring, an outer ring and a rolling assembly arranged between the inner ring and the outer ring; the inner ring is integrally formed on the inner shaft and / or the outer ring is integrally formed on the outer shaft. The inner ring and / or outer ring in the bearing are / is respectively integrally formed in the inner shaft and / or outer shaft, the structure of a main bearing is simplified and the main bearing is more timesaving and laborsaving to mount.

Description

Technical field [0001] The invention relates to the field of wind power generation equipment, and in particular to a wind power generating set. Background technique [0002] The structure of wind generators can generally be divided into two categories: doubly-fed units with a speed increasing box arranged between the impeller 2 and the generator 4 ( figure 1 ) And direct drive units without gearbox 3 ( figure 2 ). [0003] Such as figure 1 As shown, in the doubly-fed unit, when the fan is working normally, the impeller 2 rotates to drive the low-speed main shaft to rotate, the low-speed shaft drives the high-speed shaft to rotate through the gearbox 3, and the high-speed shaft drives the rotor of the generator 4 to rotate to achieve wind energy to electric energy Conversion. Such as figure 2 As shown, in a direct-drive unit, when the fan is working normally, the impeller 2 rotates, and the rotor of the generator 4 is directly driven to rotate through the rotating shaft to realiz...
