LOW-WEAR, ROBUST AND COMPACT: THE FLEXIBLE GEAR COUPLING FROM R+W

The low-wear, flexible gear couplings from R+W are used in a wide variety of industries. Particularly in heavy-duty operation – such as on the high torque shafts of mixers, rolling mills, crushers, test stands and conveyors – gear couplings transmit torques from 1,900 to 2,080,000 Nm with high torsional rigidity and low backlash. To ensure optimal performance, R+W manufactures both the coupling hubs and the flange sleeves with precise crowned gearing, made from high-strength steel.

• The high tooth contact and high-quality gearing create high torsional rigidity.
• Low restoring forces are imparted while compensating for shaft misalignment.
• The special geometry of the gearing also allows for large offset values during operation – whether they be lateral, angular or axial.
• Secure torque transmission is achieved by precision shoulder bolts with fine threads

The gear couplings from R+W bring large torque in a small package. Their high gear mesh ratio and excellent lubrication distribution make them efficient and durable. To increase service life, lubrication can be optimized with a seal made of NBR or Viton. Compared with other types of gear couplings, the R+W series is particularly easy to install thanks to the fine threaded shoulder bolts used for assembly.

The gear couplings from R+W are available in numerous variants:

• As pure gear couplings
• With cylindrical bore for shrink fitting
• With keyway connection or keyway groove
• With internal gearing
• In connection with safety couplings

The designs are also available with an optional additional brake disc or extended hubs. For better corrosion protection of the components, R+W couplings can be burnished or oxidised.
