It is common practice to produce such connecting shafts from composite tubes (either glass or carbonfibre) and to connect them by torsionally stiff, but flexible elements using a double cardanic system between the motor and gear shafts.
High critical whirling speed - thus no intermediate bear-ing necessary, even at lengths of up to 6 m. Bigger lengths on request.
Maintenance free and corrosion-proof - since all elements are made from composite or stainless steel. Alternative for cost reduction metal parts corrosion proof.
On request the drive shafts can be provided with a stainless friction plate, as well as a backstop.
The driveshafts are homokinetic and thus free of the usual occuring reaction forces of a cardan shaft.
The use in areas subject to explosion risk is possible. The driveshafts comply to the safety regulations of directive 94/9/EG. The CENTA team will gladly supply a declaration of conformity .
Load transmission of the composite shafts is ensured by a specially designed, high secure bonding, whish has prooved its worth in many years with application in ship propulsions and wind turbines.
Low weight, easy assembly, free from backlash, independant of the rotating direction, exact alignment is not necessary.
Upon correct selection and installation the drive shafts are durable. The CENTA team is at your service for council and will gladly do the shaftline selection.
no considerable thermal expansion and deformation at standstill.
Cooling towers have an external electric motor which is connected to the bevel gear - located in the centre of the cooling tower - by long drive shafts.
