Bellows couplings simplifies fitting torque flange

HBM’s T22 torque flange is now available with an optional matching bellows coupling removing the need for any additional adaptation. Most torque flanges normally require expert knowledge when fitting because transducer geometries, for example, place special demands on handling and installation, especially when conventional designs are involved.

The robust T22 torque flange can be directly mounted to the housing because of the installation between stator and rotor. However, both sides of the transducer require connection elements for compensating unavoidable assembly problems, for example, axial, radial and angular offset that are removed by the bellows coupling.

By supplying both couplings and transducer, HBM has increased the reliability.

Three types of couplings are available in steps from 5 N•m to 1 kN•m. They can be used horizontally, vertically or transversely, are maintenance and wear free, and provide high torsional stiffness. The T22’s low measurement uncertainty – 0.5 accuracy class in compliance with HBM’s demanding definition – is not negatively affected. The couplings are free of play and, when combined with a torque application via friction joints, ensure correct torque application. Depending on the size, the customer side is available for shaft diameters ranging from 15 mm to 60 mm.
