2.3 Couplings

HBM offers bellows couplings for the installation of the torque transducer. The
couplings and the torque transducer are delivered as separate items. The
following points must be observed during installation:
 Only tighten the clamping bolts of the couplings when the shafts are
mounted in the coupling hubs!
 The bellows coupling must not be overstretched beyond the specified
permissible flexibility limits.
 Drive and output shafts must be free from burrs.
 Implement a tolerance of j6 for the shaft diameter, to produce the preferred
fit of H7/j6.

2.3.1 Mounting position with couplings

The T22 torque transducer can be operated with bellows couplings in any
mounting position (horizontally, vertically or at an angle). When operating ver-
tically or at an angle, please make sure that the additional elements are
adequately supported.

2.3.2 Installation

1. Degrease the hub bores of each coupling section and shaft ends with
solvent (e.g. acetone).
2. Push the hub onto the shaft, set the reference gap L (using the full clamping
length of the coupling) and align the shaft.
3. Tighten the clamping bolts of the clamping element with a torque wrench
(necessary tightening torque, see
ATTENTION
When mounting the coupling, the permissible longitudinal and lateral
forces, and the limit bending moments of the torque transducer must
not be exceeded (see
Hold the coupling on the clamping element when tightening the
clamping bolts.
