METAL BELLOWS COUPLINGS FEATURES ▪ Metal Bellows Couplings for use with Magtrol TM, TMB, TMHS and TS Series In-Line Torque Transducers and Sensors ▪ Dedicated for transmission of High Torques ▪ High Torsional Stiffness ▪ Diameter Range: 10 ... 90mm ▪ Radial Clamping Screw hub for smooth shaft. ▪ Easy to mount. Fig. 1: BK2-80-94 | Metal Bellow Coupling DESCRIPTION BK2 Series Metal Bellows Couplings provide the ideal complement to Magtrol’s s TM / TMB / TMHS / TS In-Line Torque Transducers and Sensors, when these are to be mounted in a drive train. The torque transmission element consists of a metal bellows and 2 clamping hubs. The couplings are both torsionally stiff and flexible in order to compensate for axial, angular and radial misalignment when connecting two shaft ends. The high torsional spring rate of the couplings ensures a high torsional stiffness and angular precision. DESIGN & MATERIAL Bellows are made of highly flexible and high-grade stainless steel. The hub material is made of aluminium or steel (please see "Specifications" section). Clamping is done by a single ISO 4762 radial clamping screw per hub. For model 1500 and 4000, the clamping is performed by two opposite screws at 180 degrees. SELECTION TABLE In order to ensure a sufficient safety margin, Magtrol recom mends that couplings be sized according to the maximum torque supported by the torque transducer. It is strongly recommended to protect all rotating machine parts according to Safety Machine Norms for avoiding injuries.
