Description:
|
|
Three series of zero backlash
flexible beam couplings are available with inch and metric bores
and outside diameters ranging from 3/8" (10mm) to 1 1/2"
(38mm). Shaft couplings in all three series are machined from
a single piece of aluminum and feature multiple spiral cuts.
The multiple cut design provides higher torque capabilities
and greatly reduced wind-up when compared to commodity type
single beam couplings. |

The P-series and F-series flexible
beam couplings each have two sets of spiral slots, a feature
that provides superior parallel misalignment capabilities compared
to the single beam coupling. Angular misalignment, axial motion
and any combination of all three types of misalignment are also
easily accommodated by the beam coupling. Ruland clamp style
flexible beam couplings have the additional benefit of dynamic
balancing, due to the unique configuration of the socket head
cap screws.
A flexible beam coupling should be used in
an application in which misalignment exists between the two
shafts being coupled. The F-series couplings are ideal for light
duty power transmission applications such as coupling a servo
motor to a lead screw in a motion control system. These couplings
feature a larger body size and stronger beams to provide high
torque capacity and very low windup, while not sacrificing misalignment
capabilities. The demanding nature of reversing servo applications
make the performance benefits delivered by the F-series beam
couplings vital to maintaining the accuracy, repeatability and
reliability of the system.

The P-series flexible beam coupling is
designed specifically for precision applications, especially
those that use delicate components such as encoders and tachometers.
The small bearings on these components make low radial forces
essential to longevity and continued high performance. They
are shorter than the F-series beam couplings and conform to
industry standard lengths, fitting into confined spaces and
allowing for easy retrofits in existing equipment. At the same
time, the multiple cut pattern continues to provide excellent
torque capabilities and low windup.
