Title:
SUPPORTING DEVICE OF SHAFTING BEARING, AND WIND GENERATING SET
Document Type and Number:
WIPO Patent Application WO/2022/021535
Kind Code:
A1
Abstract:
A supporting device (1) of a shafting bearing, and a wind generating set. The shafting comprises a first shaft (S1), a second shaft (S2) sleeving the peripheral side of the first shaft, a bearing (B) arranged between the first shaft and the second shaft, and a rotating component (R) fixedly connected to the second shaft. A containing space is provided between the end face of the first shaft close to the bearing and the inner surface of the rotating component away from the bearing. The supporting device is arranged in the containing space and can provide an adjustable axial prestress load. One part of the supporting device is fixedly connected to the rotating component, and the other part of the supporting device is fixedly connected to the first shaft, so that the axial force provided by the rotating component is counteracted by the axial prestress load or transmitted to the first shaft by means of the supporting device. The device can prevent an axial load from directly acting on a shafting bearing or can reduce the axial load acting on the shafting bearing, prolonging the fatigue life of the shafting bearing.
