Modular couplings for servo drive lines
Original article date: February 1999
Built to a modular concept Mayr Transmissions’ Smartflex coupling is optimised for the requirements of servo drive lines and offers the machine designer the optimum flexibility with minimum stockholding.
Servo applications for direct drive lines are very common today. The vast increase in quantity has made the drive lines more and more economic. This has called out for a more economic but still high quality servo coupling.
The Smartflex coupling consists of a steel bellows clamped on shaft bushings by clamp collars. For installation the parts are put together and frictionally locked by clamping just one bolt each side. Hence blind assembly is possible. The clamping ring hubs are locked to the shaft frictionally by tightening the clamping bolt. This assures a backlash-free torque transmission between input and output shaft.
The modular concept allows a number of different components to be stocked without needing to stock a variety of complete couplings with different hub bores. Different shaft diameters are accommodated by a range of hub bushings of different bore.
The multiple layers of the steel bellows of the Smartflex provide extremely high torsional stiffness yet still compensate for larger shaft displacements with low restoring forces. This ensures true positioning of the drive and protects the shaft bearings from premature failure due to excessive radial loads.
Made from aluminium the hubs together with the light metal bellows provide an extremely low moment of inertia making the couplings suitable for highly dynamic fast reversing drives.
