Two new miniature bellows couplings have been launched by Motor Technology of Stockport, adding to the Company's already extensive range.
Manufactured in Germany by R+W, the MK3 and MK6 couplings are designed with expanding shafts that allow simple connection to the hollow inputs of gearboxes and other devices.
The MK6 coupling additionally features a simple plug-in design, enabling quick connection and disconnection of the driving and driven components, without the need to loosen or remove fastening screws. The Company claims this feature can cut installation time by up to 80%, and means that access windows in the adapter flange are not required.
Said to be absolutely backlash free, the new couplings are capable of transmitting up to 10Nm of torque, and the metal bellows, manufactured from high-grade stainless steel, provide torsional stiffness and compensate for axial, radial, and angular misalignment.
Both couplings are claimed to be maintenance free, can accommodate shaft sizes from 3 to 22mm diameter, and are capable of operating at speeds of up to 10,000rpm. They have been developed for use with potentiometers, tacho-generators, pulse generators, angle encoders, and small highly dynamic servo drives.
