All-steel tooth clutches for uses that require the ultimate in terms of operational reliability and service life

The GEARex® is ideally suited for use in rough environments. This coupling is not only resistant to dust, dirt, water and vibrations – it also has no trouble handling high temperatures, alternating forces and shaft misalignments. The special toothing of the crowned gear coupling offers a long service life with minimal wear. GEARex® couplings comply with the AGMA standard (American Gear Manufacturer Association).

Highlights

  • Double-cardan crowned gear coupling
  • High torques despite small installation dimensions
  • Extremely easy maintenance while in fitted state
  • Compensates for misalignments (axially, radially, and angularly)

Structure and function

The GEARex® works according to the crowned gear principle. Chamfer pressure is avoided via the special crowned toothing in the event of angular and radial misalignment. The permanent grease lubrication ensures favourable friction conditions in the toothing. This combination enables wear-free operation and a long service life for the coupling.

Features

  • Outstanding torque / size ratio
  • Compact dimensions and low dead weight with low mass inertia
  • Outfitted with special lubrication ports for extremely easy maintenance while in fitted state

Application area / utilisation

  • General mechanical and plant engineering
  • Pump drives
  • Compressors
  • Steelworks sector
