The performance skidded with both ends insulation, therefore require high, manufacture difficulty greatly than general industry shaft coupling and have higher machinery
Performance requirement.China's wind-power electricity generation is started late, and the technology of wind power generating set mostlys come from foreign countries, currently, flexible connection
The axis device overwhelming majority is not allowed to decompose, can only integrally be assembled using external imported with original packaging commodity, import flexible coupling, whole flat
Weighing apparatus can not be repaired in use when flexible coupling failure, can only rent expensive goliath or large-tonnage
Lifting appliance repair and replacement.It is small outer in external conical sleeve and inner conical drogue and generator side coupling assembly in brake disc component
Tapered sleeve and small inner conical drogue are all made of key connecting, and structure and manufacturing process are more complex.Wind power generating set in operation, flexible shaft coupling
Device has the function of effective restraining moment, and the friction plate in the intermediate connected body component of flexible coupling is after certain time use
Abrasion is had skidded, the stability of the transmitting power of generating set is influenced, in the prior art, because of the damage of friction plate single component
Also it needs entire flexible coupling part replacement could ensure the normal operation of wind power generating set；Wind power generating set is general
It all build outlying mountain area, desert innerland or sea in, therefore repairs replacement flexible coupling and need using Large-scale Hoisting lifting equipment,
Or marine large-scale lifting ship, wind power generating set tower height up to tens meters, no matter land wind field, marine wind field, lifting equipment lease
Somewhat expensive, maintenance cost and at high cost, maintenance time is long, it is difficult to guarantee the reliable and stable of downstream user electricity consumption.
