Flexible Shaft Coupling

SPIRAL COUPLING

SPIRAL COUPLING
Flexible shaft coupling 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 :
bullets
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.
bullets
Torsionally Flexible / Stiff - Producing constant velocity assuring smooth bearing loads.
bullets
Takes misalignment - Leteral (typically 0.2mm) & Angular (Typically 5 degrees).
bullets Permits slight axial movement.
bullets Precise concentric integral set screw or collet / flange type clamping.
bullets Compact - space saving and lighweight with low interia.
bullets Suitable as diameter convertor.
bullets Import Substitute available.

 
Applications :
bullets
Shaft encoders.
bullets
Tachogenerator.
bullets
Potentiometers & Variacs.
bullets Stepper & Synchronous motors.
bullets Damper & Fan Drives.
bullets All rotary precision position Transmitters.

 
Options :
bullets
Different Diameters & Bore sizes.
bullets
Higher torsional torque in steel versions.
bullets
With different clamping styles.
bullets With inserts for electrical / thermal isolation.
bullets Import substitutes.

BELLOW COUPLING
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 :
bullets
Hubs available in aluminum alloy, st. steel, brass, nylon material.
bullets
Inbuilt flange clamping or set screw clamping.
bullets
Angular offset upto 7 degrees.
bullets Parallel offset upto 0.5mm. No backlash.
bullets Constant velocity transmission.
bullets Tortionally stiff.
bullets Zero maintainance

 
Application :
bullets
Shaft Encoder.
bullets
Tachogenerator.
bullets
Potentiometers & Variacs.
bullets Stepper & synchronous motor.
bullets Damper Drives.
bullets Rotary position transmiter.

 
Option :
bullets
Different Dia & Bore sizes.
bullets
Higher trosional Versions.
