What are coupling disc packs?
What are coupling disc packs?Coupling disc packs (also called disc packs or disc pack assemblies) are key components used in disc couplings, which connect two rotating shafts in mechanical power-transmission systems.
What they are made of
- Typically made from high-strength stainless steel
- Constructed from multiple thin, flexible metal discs
- Discs are stacked and bolted together to form a pack
What they do
Coupling disc packs:
- Transmit torque between two shafts
- Flex elastically to accommodate:
- Angular misalignment
- Axial movement
- (Limited) parallel misalignment
- Do this without lubrication and without backlash
Why they are used
Because of their design, disc packs offer:
- High torsional stiffness (accurate motion transfer)
- Zero backlash (ideal for precision equipment)
- No wear parts (long service life)
- Maintenance-free operation
- Ability to operate at high speeds and high temperatures
Common applications
Coupling disc packs are widely used in:
- Pumps and compressors
- Turbines
- Generators
- Gearboxes
- Industrial motors
- High-precision machinery (e.g., CNC machines)
How they work (simple explanation)
he thin metal discs bend slightly when shafts are misaligned, but remain strong in rotation. This allows the coupling to stay rigid in torque transmission while still being flexible enough to protect connected equipment from stress.
