Only the Schmidt Offset Coupling, which requires a minimum offset,
offers so much flexibility in shaft displacement while maintaining
undisturbed power transmission at constant angular velocity. The
coupling does not add secondary forces to the drive. It also will not
transmit radial vibration between the drive and the driven shafts. It is
a dynamically clean drive which will help provide a smooth flow of power
for maximum product quality, and, unlike universal joints, there is no
performance loss by increasing shaft offset.
Standard Schmidt Offset Couplings are available for parallel shaft
displacement from a minimum of 4 to 440 mm and torque capacities from
6.2 to 51864 Nm. Special coupling sizes can be manufactured for any
specific customer requirement. The L100 series couplings will handle
parallel shaft displacement from a minimum of 4 mm to a maximum linear
shaft displacement of 77 mm with torque ratings from 6.2 to 146.8 Nm and
shaft speeds up to 4000 RPM. The L100 series is especially suitable for
applications in business machines, optical, electronic equipment and
robotics.
The L200 and L300 series couplings are capable of handling parallel
shaft displacement from a minimum of 11 mm to a maximum linear shaft
displacement of 440 mm with torque ratings from 71.9 to 51864 Nm and
shaft speeds up to 2500 RPM. The L200 and L300 series are equipped with
caged type needle bearings. The shafts are hardened and serve as the
inner race of the needle bearings. The coupling can be mounted on shaft
hubs or directly to existing flanges. This mounting technique permits
installation of the offset coupling without any need to move either of
the shafts being coupled.
The Schmidt Offset Coupling has a slight built-in axial freedom to
compensate for thermal shaft expansion and assembly tolerances. The
maximum angular shaft misalignment should be kept under one-half (%)
degree.
