RB

Manufactured in SG iron for torques up to 41kNm. Renold's Hi-Tec RB general purpose range of couplings, are incredibly cost effective.

 

The Standard Range Comprises

  • Shaft to shaft
  • Shaft to shaft with increased shaft engagement
  • Flywheel to shaft
  • Flywheel to shaft with increased shaft engagement

Applications

  • Generator sets
  • Pump sets
  • Compressors
  • Wind turbines
  • Metal manufacture
  • Bulk handling
  • Pulp and paper industry
  • General purpose industrial applications

 

Features

  • Intrinsically fail safe
  • Control of resonant torsional vibration
  • Maintenance free
  • Severe shock load protection
  • Misalignment capability
  • Zero backlash
  • Low cost

 

Benefits

  • Ensuring continuous operation of the driveline in the unlikely event of rubber damage.
  • Achieving low vibratory loads in the driveline components by selection of optimum stiffness characteristics.
  • With no lubrication or adjustment required resulting in low running costs
  • Avoiding failure of the driveline under short circuit and other transient conditions.
  • Allows axial and radial misalignment between the driving and driven machines.
  • Eliminating torque amplifications through precompression of the rubber elements.
  • The RB Coupling gives the lowest lifetime cost.

Construction Details

  • Spheroidal graphite to BS 2789 Grade 420/12.
  • Separate rubber elements with a choice of grade and hardness with SM70 shore hardness being the standard.
  • Rubber elements which are totally enclosed and loaded in compression
