Spiral
Coupling
 |
It adjusts
itself to the misalignment (angular, parallel,
skew) of the two shafts connected by it &
transmits torque & motion from one shaft to the
other. Features include one piece construction made
of aluminium alloy or stainless steel material. Flange
or set screw clamping. Offset adjustment upto 5 Deg.
and parallel upto 0.2 No. backlash with constant velocity
transmission. These coupling are widly used to couple
tachogenerators, encoders etc. |
|
Features
:
• Monolith Construction Backlash free - precision
information transmission in both directions of motion
without loss. This is possible due to the monolith construction
of the body.
• Torsionally Flexible / Stiff
- Producing constant velocity assuring smooth bearing
loads.
• Takes misalignment - Leteral (typically 0.2mm)
& Angular (Typically 5 degrees).
• Permits slight axial movement.
• Precise concentric integral set screw or collet
/ flange type clamping.
• Compact - space saving and lighweight with low
interia.
• Suitable as diameter convertor.
• Import Substitute available. |
| |
|
Applications
:
• Shaft encoders.
•
Tachogenerator.
• Potentiometers & Variacs.
• Stepper & Synchronous motors.
•
Damper & Fan Drives.
• All rotary precision
position Transmitters. |
Options :
• Different Diameters & Bore sizes.
•
Higher torsional torque in steel versions.
•
With different clamping styles.
• With inserts
for electrical / thermal isolation.
• Import
substitutes. |

BELLOW
COUPLING
 This
bellow coupling connects two shaft to transmit torque,
motion etc. It is a coupling which can adjust itself
to misalignment of two shafts connected by it. Misalo\ignment
may be angular, parallel or skew. When motion transmission
is important. The misalignment should not affect the
velocity & acceleration of the shaft. This calls
for a torsionally rigid, yet Flexible Coupling.
This coupling offer you this advantage using bellow
& two hubs. Given in this leaflet are various coupling
used in listed applications. |
| |
Features
:
• Hubs available in aluminum alloy, st. steel, brass,
nylon material.
• Inbuilt flange clamping or
set screw clamping.
• Angular offset upto 7
degrees.
• Parallel offset upto 0.5mm. No backlash.
• Constant velocity transmission.
• Tortionally
stiff.
• Zero maintainance |
Application
:
• Shaft Encoder.
•
Tachogenerator.
• Potentiometers & Variacs.
• Stepper & synchronous motor.
• Damper
Drives.
• Rotary position transmiter.
Option :
• Different Dia & Bore sizes.
• Higher
trosional Versions. |
