TWINTORS® Diaphragm Couplings
Since the patented T WINTORS coupling‘s initial introduction in the mid-eighties, BHS has expanded the product line to include six main design configurations.
These coupling d esigns offer
significant room for future development in terms of power and
compensating capability.
The Concept
As a manufacturer of high performance gear units,
BHS offers a coupling with minimum weight and volume capable of transmitting maximum torque:
Torsion-proof, zero-backlash allmetal coupling to compensate the axial, radial, and angular misalignment of two coupled shafts
Double diaphragm for double compensation of shaft misalignment
Lightweight design resulting from electron-beam welding
Fig. 1
Safety Due to
Superior Design
Rating of components
supported by FEM
The radially elastic outer
connecting ring of the diaphragms
reduces material stresses caused
by deformation in case of axial
shaft misalignment
Component endurance verified on
fatigue test stand.
Diaphragms are
electron-beam welded
100% ultrasonic inspection
Corrosion resistant diaphragm
elements
Meets the requirements of
API 671, ISO 10441 and ISO 14691
Advantages of the
TWINTORS® Diaphragm
Coupling
High torques can be transmitted
at highest speeds
Low restoring forces even if
severe shaft misalignment is
compensated
Low masses and mass moments
of inertia, minimum number
of components
High running precision due
to zero backlash
Balancing of individual
components and the complete
coupling
Low windage loss and noise
Compact coupling guards
No change in flexibility over
the entire service life, no wear by
abrasion, no scuffing and
minimum stress concentration
Lubrication and maintenance free
Simple rotor dynamic adaptation
possible thanks to module system
and FEM
Optimized weight of coupling hubs
Operable in vertical and
horizontal positions
Short delivery times due to the use
of standard components
Cost effective design without

MKA xxx-ASS
Diaphragm type A, standard hub,
flange-mounted spacer
Dismantling subassembly: spacer
- diaphragm elements
High torsional stiffness
High misalignment compensation
MKA xxx-AAE
Diaphragm type A,
standard hub welded-in-spacer
Dismantling subassembly:
welded-in-spacer with
diaphragm element
Low weight
High torsional stiffness
High misalignment compensation
MKB xxx-AAE
Diaphragm type B, standard hub, welded-in-spacer
Dismantling subassembly: welded-in-spacer with diaphragm elements In comparison to MKB xxx-ASS lower weight Fig. 5 Fig. 6
Examples of Applications

Maximum importance is at-tached to high balancing quality. After the balancing of compo-nents, BHS can also carry out complete balancing; very few other manufacturers have this capability.
