Flexible Disc Coupling

  • Eliminates the need for lubrication and coupling maintenance
  • Coupling can be inspected without disassembly
  • Condition of disc packs can be inspected with a strobe light while the machine is running
    (Note: It is not recommended that couplings be operated without coupling guards.)
  • Easy to assess equipment misalignment
  • Torsionally rigid without any backlash
  • No wearing parts
  • Resistance to harsh environments
  • Long life when properly sized and aligned
  • High power density (higher torque for a given outside diameter)
  • Lovejoy supports the API-610 Standard up to 3,800 RPM
  • Unitized disc packs ensure repeatability necessary for meeting the balance and piloting requirements as mandated by API-610
  • ATEX Certified for SU, SX, DI, SXC, SXCS, SXCST, DIR, DILR, DIRA and DIRLA product lines

NER Series

1.Large transmission capacity Greatly increased torque relative to previous series enables smaller sizes. 2.Easy handling The disks and spacers have been structured as a single unit(center unit), eliminating on-site disk assemble work after centering. Can be installed/removed just by the bolts between the center unit and hubs. 3.Large bore diameters The use of a center unit enables larger maximum bore diameters than other models. 4.Backlash-free, long service life NER Series models have no backlash and high torsional stiffness, making them ideal for servomotor-based positioning equipment. No sliding parts, enabling long-term use without lubrication. 5.Wide range of options Support a wide range of options such as reinforced plastic spacers, shaft coupling in Power-Locks, and flange attachments. 6.Environmentally friendly Comply with the regulation on hazardous substances in RoHS directive.

FNC Series

The trusted TB Woods Form-Flex metal disc style shaft coupling has successfully been used in conjunction with composite shafting for many years. If an application has a large distance between the driver and driven ends, the traditional design would be to incorporate a steel drive shaft between the two flexible coupling units. However, using steel shafting in this way can have its disadvantages. Primarily, the weight of the connecting shaft could mean additional bearing mounts and inertia problems to the whole design especially when large span distances are required and again when using couplings suited to bore sizes of 25mm and above. (Max 400mm).  To overcome this the spacer shaft was supplied using a composite material shaft . The key advantages to using composite shafting lies its weight saving characteristics and the inherent nature to reliably transmit high torques with near zero torsional wind up.

 

Dodge poly-disc couplings

The Dodge Poly-Disc coupling features a molded polyurethane disc that helps cushion shock loads and resists chemical attack. Easily assembled, the flexible Poly-Disc element utilizes spacer buttons to quickly set correct flange spacing, while the fully machined flanges utilize standard Taper-Lock bushings for easy installation and removal. The Poly-Disc coupling requires no lubrication or periodic maintenance, ensuring worry-free operation.

Features

  • Elastomeric coupling with a polyurethane flexible disc
  • Polyurethane flexible disc resists chemical attack
  • Allows 2° of angular misalignment and cushions shock loads
  • Accommodates up to 3-1/4″ boxes and 10,900 lb-in
