Description
The disc pack accommodates angular misalignment from 1/2° to 1-1/2° and is used in all disc couplings.
The discs are manufactured from high-quality stainless steel (AISI-301), which guarantees high strength, excellent fatigue resistance, and resistance to most environmental conditions. Disc couplings use disc packs with 4, 6, or 8 bolts. Although the 8-bolt design can transmit higher torque than the 6- or 4-bolt designs, it does not allow for much angular misalignment. In addition, couplings can be equipped with overload bushings to protect the discs during momentary torsional overloads.
Main features
- Complies with regulations for potentially explosive atmospheres (ATEX and A.P.I. 671/610)
- Eliminates the need for lubrication and coupling maintenance
- The coupling can be inspected without dismantling it
- It is possible to inspect the discs with a strobe light while the machine is running (Note: it is not recommended that couplings operate without coupling guards).
- Misalignment of equipment easily assessable
- Torsionally rigid with no backlash
- No wearing parts
- Resistance to harsh environments
- Extended service life if dimensions and alignment are correct High power density (higher torque for each given outer diameter) Unified discs ensure the repeatability necessary to meet the balance and connection requirements specified by the API-610 standard ATEX Certified for SU, SX, DI, SXC, SXCS, SXCST, DIR, DILR, DIRA, and DIRLA
