R&D Couplings

Description

R & D Marine Flexible Shaft Couplings

The R&D 910 Series couplings consist of a contoured flexible disc moulded in tough yet resilient new type Polyurethane Elastomer.
 
The contoured disc gives clearance for the bolt heads, is able to flex freely to take up any temporary misalignment of the engine and shaft, due to flexing of the boat structure or the engine moving on its rubber vibration isolation mountings. Forward thrust is taken in compression on the disc between the two half couplings and reverse thrust is taken again in compression on the disc between the two fail straps.
 
In the unlikely event of a disc failure the steel straps make the coupling fail-safe and ensure drive is maintained in both forward and reverse.
 
Features:
  • Bolts between existing shaft flanges
  • Requires no machining
  • Simple to install
  • Simple to periodically check alignment
  • Reduces engine noise and vibration
  • Fail safe design

Note: All flexible couplings are supplied with nuts and bolts ready for installing.
