COMPARATION OF SELECTED PNEUMATIC FLEXIBLE SHAFT COUPLINGS

At our Department we deal with the development of pneumatic flexible shaft couplings, which in addition to other flexible couplings are able to change their torsional stiffness by adjusting the air pressure in their flexible elements. This article deals with comparison of two selected pneumatic flexible shaft coupling. The first coupling is a newly developed pneumatic flexible shaft coupling with wedge elements. Pneumatic flexible shaft coupling with wedge elements was developed to improve the properties of pneumatic flexible couplings, especially the nominal and maximal torque and maximum angle of distortion. Due to the reason that coupling with wedge elements isn't manufactured yet, we will use only a mathematic model of this coupling. The second coupling is a tangential pneumatic flexible shaft coupling manufactured by FENA company.
