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).
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.
