A flexible coupling is a mechanical element composed of rubber elements. It is installed on a 4-stroke engine and connects two shafts together to transmit torque while allowing for some degree of misalignment and angular movement. A flexible coupling additionally reduces the stress and wear on the shafts and other components in the system by dampening vibration.Available in a variety of materials and configurations, CENTA couplings accommodate many different applications and industries. Size, geometry, and material characteristics are relevant for the transmission of the torque. The variation in operational conditions will inevitably affect elements during operations.
When to service CENTA flexible couplings?
Rubber is a natural material that hardens over time and loses its flexibility. For that reason, carrying out an annual inspection of the condition of the rubber is recommended by the OEM according to the following intervals:
- after 1,000 operating hours
- after 4,000 operating hours
- Thereafter every 6,000 operating hours or annually (whichever is earlier)
The periodical inspection of the couplings, according to manufacturers’ recommendations as stated above, is required by the relevant classification societies.After 10 years or 50,000 running hours, it is recommended that the rubber segment of the coupling is replaced.
Why service flexible couplings?
Risks of delayed servicing of CENTA couplings:
- Exposure of the drive train and all connected system components to stresses beyond their limits
- Premature wear and tear on components in the drive train
- Failure of the bearings in driving and driven parts
- In case of failure, the lead time for the rubber component replacement can be more than 8 weeks
- Annual inspection of CENTA couplings product line
- Rubber element replacement services and repairs for entire CENTA product line
- Original spare part kits
- Alignment checks, including the foundation of engine arrangement or propulsion line
- Replacement of resilient mountings
- All services are carried out by expert MAN engineers
