POLY-NORM® - torsionally flexible jaw coupling with shallow installation depth
Reliable compensation of shaft offsets and torque transmission
POLY-NORM® comes with an axial plug-in and is characterised in particular by its short design. It is used in almost all areas of general mechanical engineering and the pump industry. The POLY-NORM® coupling competently compensates for shaft misalignments of any kind and reliably transmits the torque.
Features of the various POLY-NORM® designs
| Feature | Designation of the coupling |
|---|---|
| Elastomers can be disassembled radially -> without shifting the drive/output end | ADR, ADR-SB |
| Intermediate shaft designs -> bridges larger shaft gaps | - |
| Standard extension piece 100 mm to 250 mm | - |
| Shaft-shaft connection | Standard |
| Flange-shaft connection | - |
| Flange-flange connection -> particularly short installation length | - |
| Double-cardan | - |
Highlights

Structure and function
The POLY-NORM® coupling consists of two hubs, with cam and pocket elements alternately arranged on the circumference of the face, which are inserted blindly into each other axially, offset by half a cam pitch. In precisely fitting clearances, half the elastomer ring is clamped in each coupling hub and thus transmits the torque in a space-saving manner solely via a pressure load in the elastomer.
