Coupling Rod and Articulation
Bridging Motor and Rotor
In eccentric screw pumps, a coupling rod with articulation is indispensable for connecting the motor to the rotor. This articulation accommodates the inherent misalignment and offset between the motor’s rotational axis and the rotor’s eccentric axis.
Two Main Coupling Types
- Rod + Pin Joint
This simple and cost-effective coupling employs a rod with a pin joint at each end, allowing for angular misalignment. However, it may transmit some vibration and requires precise alignment for optimal performance. - Cardan (Universal) Joint
Comprising two yokes connected by a cross-shaped link, the Cardan joint offers greater flexibility, accommodating both angular and axial misalignment. This results in smoother power transmission and reduced vibration, making it suitable for demanding applications.
Benefits of Each Type of Couplings
Rod + Pin Joint:
- Cost-effective
- Simple design and maintenance
- Suitable for applications with minimal misalignment
Cardan Joint
- Superior flexibility, handling both angular and axial misalignment
- Smoother power transmission and reduced vibration
- Ideal for high-performance and heavy-duty applications
