Ruland DiscflexTM
Coupling
The Ruland DiscflexTM Coupling
is designed as a Zero Backlash coupling. They are an assembly of two
anodized aluminium hubs, multiple flat stainless steel disc
springs and a center spacer for double disc styles. The thin
discs allow for a substantial amount of misalignment between
shafts while remaining rigid under torque loads. Parallel
misalignment is accommodated by the double disc style or by two
single disc couplings used in tandem. This results in a high
performance motion control coupling with excellent strength and torsional stiffness
characteristics, high speed capabilities up to 10,000 rpm, and low inertia for today's highly responsive
systems.

Double disc couplings are used in typical servomotor lead screw
applications while single disc couplings can be used when a
longer distance is required such as on gantry systems.
The DiscflexTM couplings are
offered in standard sizes with outside diameters from 15mm to
57mm in both Nomar® clamp style and set screw style. Bore sizes
from 1/8 inch to 1.1/4 inch are available as well as 3mm to 30mm
sizes in the metric series. |
