Embodiment Construction

[0068] In order to solve various problems existing in the prior art, the inventors of the present invention propose a A new type of heating device, heating method and shafting assembly method for large-scale, large-mass, variable-diameter, non-equal-section components. Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so as to fully convey the technical concept of the present invention to those skilled in the art.

[0069] In order to avoid the problem that the inner ring of the bearing and the outer ring of the bearing collide with each other and cause damage to the bearing during the process of fitting the rotating shaft to the main shaft of the stator, the embodiment of the present invention still adopts the rear bearing between the main shaft of the stator and the rotating shaft during the fitting process. "One whole" thinking.

[0070] In the case of the rear bearing as a whole, in order to ensure the in...

Abstract

The present invention provides a heating device of and a heating method for a large shafting component for a wind driven generator and a shafting assembling method. The heating device comprises: a flexible heating membrane configured to be coated on a surface of a to-be-heated member; a vacuumizing system configured to vacuumize the flexible heating membrane in the case that the flexible heating membrane is hermetically coated on the to-be-heated member; and a control unit configured to control the heating operation of the flexible heating membrane and the operation of the vacuumizing system. The technical solution of the present invention solves the assembling quality problem caused by uneven heating in the traditional heating method and assembling method, and is more energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the field of shaft assembly of wind power generators. More specifically, the present invention relates to a heating device for heating a large-scale, large-mass, variable-diameter, non-uniform cross-section component to be heated, such as a rotating shaft of a wind power generator, and using the heating device to heat such A method for heating parts to be heated, and a method for assembling a generator shafting. Background technique [0002] The wind power generator includes a stator main shaft supporting the stator and a rotating shaft supporting the rotor, and the stator main shaft and the rotating shaft are relatively rotatably assembled together through bearings. For large wind turbines, it is necessary to install front and rear bearings between the stator main shaft and the rotating shaft. Taking a large direct-drive permanent magnet wind turbine with an outer rotor structure as an example, the main shaft of the generato...
