Rotary Motion and Power Trasnmission
FLEXIBLE SHAFT COUPLINGS
Its main function is to compensate for misalignment and absorb vibrations, which helps to protect the connected components and improve the efficiency of motion transmission.
APPLICATIONS
Flexible shaft couplings are used in a wide range of industrial sectors:
- Robotics: Connect and transmit motion between the motor axes and the joint axes of the robot. This allows for greater flexibility and motion capability in assembly, handling and welding operations.
- Packing, Packaging: Transmit motion from motors to feed rollers, cutting systems and sealing systems. This ensures accurate and smooth transmission of motion in the filling and packaging process.
- Automated conveying systems: Connect and transmit the motion between the motor shafts and the conveyor rollers or wheels. This allows smooth transmission of motion and vibration absorption in conveying materials and products.

In this application we see a two-axis positioning
machine for the assembly of a plate.
The flexible couplings are responsible for transmitting
the rotary power from the motor to the spindle.

TYPES OF MISALIGNMENT
Among its main advantages are the following:
- Stand out for their high accuracy in a positioning application.
- Provide safety in dynamic movements and protection to the system by withstanding certain degrees of
misalignment and vibrations.
Declination
(Angular Misalignment)
Angle error between two axis
centers.
Eccentricity
(Lateral Misalignment)
Error of parallelism between two axis centers.
End Play
(Axial Misalignment)
Displacement of the shaft in the axial direction.
Any of these three options can be chosen to attach the tracker to the desired structure.
