QUESTION:

 

 

 

 

 

What are the most common types of couplings and what typical characteristics do they have?


ANSWER / REMEDY / NOTES:

     

  

1.

Tooth coupling

 

 

·       Double-jointed tooth coupling for compensating angular displacement, parallel and axial misalignment

·       Low restoring force in the case of shaft misalignment

·       Long-term lubrication

·       Small dimensions

·       Can be used with high impact loads

·       Can be used for both directions of rotation

2.

Multiple-disc coupling

 

 

·       Zero backlash, torsionally rigid solid steel coupling

·       Compensation of radial, angular and axial shaft misalignments with two flexible disc packages

·       Stainless steel disc packages are not subject to wear

·       Simple installation

·       High temperature range of up to 280 °C

3.

Elastic pin coupling

 

 

·       Elastic, buckle-proof, universal coupling for the highest torques with good repositioning option

·       Compact and lightweight design, low moments of inertia

·       Suitable for plug-in assembly

4.

Flexible claw coupling

 

 

·       Flexible, buckle-proof universal coupling

·       Extremely compact design, high power density

·       Ideally suited for plug-in assembly

5.

Hydraulic coupling

 

 

·       Smooth and jolt-free start-up and acceleration of large masses for non-loaded motor start-up

·       Torque limitation during start-up and in the event of an overload

·       Outstanding vibration isolation and shock absorption

·       Non-wearing torque transmission
