Description
Technical field
The utility model is related to a kind of shaft coupling, more particularly to a kind of high speed shaft of aerogenerator shaft coupling.
Background technology
The shaft coupling of the high speed shaft of wind power generating set is for the important of connection gear box high speed shaft and generator shaft
Part.Wind-power electricity generation mainly rotarily drives set main shaft rotation by wind drive fan blade, first after gear-box speedup, then leads to
Cross high speed shaft shaft coupling and be transferred to alternator shaft, so as to convert wind energy into electric energy.Due to wind-power electricity generation be in heavy duty, shake
Special operation condition that is dynamic, becoming moment of torsion and start repeatedly, high speed shaft shaft coupling needs axial direction, radial direction and the angle by compensating shaft system of unit
The modes such as displacement, to balance the additional energy that unit is produced by the fluctuation of external load, it is necessary to be short-circuited in unit or
It is automatic to skid during overload, to reach the purpose of protection unit.How to overcome what wind-powered electricity generation shaft coupling two ends moment of torsion and vibration were caused
The operating mode of two Shaft misalignments, is the manufacture problem of wind-powered electricity generation high-speed coupling.
