Couplings

HBM supplies bellows‐type couplings for the installation of torque transducers.
When prepared for delivery, the couplings and the torque transducer are kept
separate. The following points must be observed during installation:
S Only tighten the clamping screws of the couplings once the shafts are
installed in the coupling hubs!
S The bellows‐type coupling must not be overstretched beyond the specified
permissible flexibility.
S Drive and output shafts must be without burr.
S Run the shaft diameter with j6 tolerance, to produce the preferred fit H7/j6.
4.3.1

Installation position with couplings

With the bellows‐type couplings, the T21WN torque transducer can be oper­
ated in any installation position (horizontal, vertical or diagonal). With vertical
and diagonal operation, make sure that additional frames are adequately sup­
ported.
4.3.2 Installation
1. Degrease the hub bore of each coupling half member and the shaft ends
with solvent (for example, acetone).
2. Push the hub onto the shaft, set the reference gap L (making use of the full
clamping length of the coupling) and align the shafts.
3. Tighten the clamp element clamping screws with a torque wrench (for the
required tightening torque, see Tab. 4.1).
CAUTION
When installing the coupling, you must not exceed the permissible axial and
lateral forces or bending limit moments of the torque transducer!
When tightening the clamping screws, hold the coupling on the clamp element.
