Clamp coupling DIN115

The clamp coupling according to DIN115 is a torsionally rigid shaft connection with various advantages. The coupling can absorb impacts and radial or axial loads exceptionally well. The coupled shafts are always in exact aligned. The radially screwed coupling ensures easy assembly. The shells are perfectly aligned with each other to ensuring a safe and secure screwed connection. Due to the slitting of the coupling, the application is ideal for shafts connected in series (e.g. transmission shafts).

When coupling shafts have different diameters, we recommend that the thicker shaft end be machined down to the diameter of the smaller one. If this is not possible, the version corresponding to the larger shaft diameter is used with a stepped bore. (Form B).

The vibration caused by the material wear is kept within permissible limits, as is the wear (abrasion) caused by the sliding movement. Due to the absolutely identical coupling halves, the forces resulting from the torque are absorbed by both of the soft material rings, which is thus the reason for the good torsional elastic and flexible properties of the double-flex coupling.

Unless otherwise specified in the order, the double-flex couplings are drilled according to ISO H7. Grooves for parallel keys DIN 6885-1 or tapered wedges DIN 6886.
