A stainless steel bellow provides compensation for both misaligment or axial displacement between the two shafts. The couplings are particularly suitable for the rotationally stiff driving of high resolution angle transducers.
For the BKA coupling each of the shafts are attached with hexagon socket set screws. The hubs are in aluminium. The bellow material is stainless steel. The service life of the couplings (number of turns or changes of load) depends on the following factors and can therefore only be reliably determined in practical tests: Torque and moment of inertia of the driven transducer, actual parallel and/or angular offset, axial play in the driven shafts and the ambient temperature must be taken into consideration.
In the BKK coupling, a stainless steel bellows serves as a compensating element for the misalignment or axial displacement of two shafts. They are particularly suitable for torsionally stiff drives of high-resolution rotary angle transducers. The shafts of the BKK coupling are fastened with clamping hubs. Hubs and screws are made of stainless steel. The service life of the couplings (number of revolutions or load changes) depends on the following factors and can therefore only be reliably determined in practical tests: Torque and moment of inertia of the driven encoder, actual parallel and/or angular misalignment, axial clearance of the shafts and ambient temperature are essential parameters.
