Power Transmission Couplings
Power transmission couplings are designed to transfer power from one shaft to another in rotating equipment. They can accommodate misalignment, reduce transmission of shock loads and provide a disconnection point for maintenance or alteration of the machinery.
Here are some of the primary purposes of power transmission couplings:
- Transmitting Power: Connect two shafts to transfer power from one to another efficiently.
- Accommodating Misalignment: Tolerate misalignments between shafts without causing stress or damage.
- Facilitate Maintenance: Serve as a disconnect point for easier disassembly and maintenance of machines.
- Safety and Overload Protection: Designed to act as a safety device, failing in a controlled manner under overload conditions to protect other machinery components.
- No Slip Power Transmission: Provide a direct link for accurate, slip-free power transfer.
- Reducing Wear and Tear: Significantly decrease wear and tear on bearings and other machinery components by compensating for misalignments with reduced loading.
- Reduced Maintenance and Downtime: In the case of non-lubricated couplings (disc, diaphragm, elastomeric or rigid), there is no need for regular maintenance checks and lubrication, as a result, increasing your plant’s uptime and profitability.
- Conserving the Environment: Disc and diaphragm couplings are designed for infinite life, therefore minimizing your carbon footprint and costs.
