Application not outside buildings. 3) Each type of irregular stress (bending moment, lateral or longitudinal force, exceeding nominal (rated) torque) can only be permitted up to its specified static load limit provided none of the others can occur at the same time. If this condition is not met, the limit values must be reduced. If 30% of the bending limit moment and lateral limit force occur at the same time, only 40% of the longitudinal limit force is permissible and the nominal (rated) torque must not be exceeded. The permissible bending moments, longitudinal forces and lateral forces can affect the measurement result by approx. 1 % of the nominal (rated) torque. 4) The nominal (rated) torque must not be exceeded. 5) Please adhere to the maximum torque (T max ) of the couplings. 3 HBM

The bellows coupling must not be overstretched beyond the specified permissible flexibility limits. Drive and output shafts must be free from grease and burrs. Implement a tolerance of j6 for the shaft diameter, to produce the preferred fit of H7/j6. Mounting position The T22 torque transducer can be operated with bellows couplings in any mounting position (horizontally, vertically or at an angle). When mounting vertically or at an angle, please make sure that the additional elements are adequately supported. Delivery condition The couplings and the torque transducer are delivered as separate items.
