FLENDER Standard Couplings
Flexible Couplings – BIPEX-S Series
General
■
Overview
BIPEX-S couplings are torsionally flexible and are free of back-
lash in the pretensioned state. They are characterized by their
compact design and high power density. BIPEX-S couplings
connect machine shafts and compensate for shaft misalignment
that can occur during assembly or operation. The damping
properties of the couplings can be varied by the use of cam
rings made of elastomer of various degrees of hardness.
BIPEX-S couplings are suitable for all drive applications which
require a coupling that offers positioning accuracy and vibration
damping.
■
Benefits
BIPEX-S couplings are suitable for mounting horizontally, verti-
cally or in any desired position. The coupling parts can be ar-
ranged as required on the shaft ends to be connected. The cou-
pling can be axially plugged in.
The cam ring is pretensioned and is therefore assembled without
backlash. The cams attached to the cam ring allow the coupling
to compensate shaft misalignment, and also provide electrical
isolation since they prevent contact between the two hub parts.
BIPEX-S couplings are fail-safe. When the cam ring is worn, the
claws of the coupling hubs provide for fail-safe operation.
Available in 4 different Shore hardness grades, the cam rings al-
low to select the optimum degree of rigidity for any application.
■
Application
BIPEX-S couplings within the standard catalog range are avail-
able in 10 sizes with torque ratings ranging from 0.5 to 655 Nm.
The coupling is suitable for ambient temperatures of between
-30 °C and +90 °C. Cam rings with alternative hardness grades
can be supplied for ambient temperatures down to -50 °C or up
to +120 °C.
BIPEX-S couplings are ideal for use in servo drives, linear axes
or rotary encoders of the type typically deployed in machine
tools, packaging machines or printing presses.
