Title:

HEATING DEVICE FOR BEARING PROTECTION OF WIND POWER GENERATOR AND BEARING SYSTEM

Document Type and Number:

WIPO Patent Application WO/2016/169263

Kind Code:

A1

Abstract:

A heating device (1) for bearing protection of a wind power generator and a bearing system, wherein the heating device (1) is applied to a main shaft of the wind power generator that is externally provided with a bearing (21), and the heating device (1) is disposed inside the main shaft at a position corresponding to the position of the bearing (21). The heating device (1) comprises a plurality of circular arc sections (11), a flexible heat source (12) and a supporting device (13). The flexible heat source (12) is provided between the circular arc sections (11) and an inner wall of the main shaft. The supporting device (13) supports the internal surface of the circular arc sections (11), so that the flexible heat source (12) is closely adhered to the inner wall of the main shaft. A heat source is provided for the bearing by the heating device (1) for bearing protection of a wind power generator and the bearing system, so that bearing grease will not freeze and the bearing grease can remain fluidized, which prolongs the service life of the bearing and realizes close contact between the flexible heat source and the inner wall of the main shaft of the wind power generator.
