Flexible Shaft Couplings

1 Flexible Shaft Couplings For engines 5 to 1500 HP Reduces engine noise andvibration transmission Fail safe design Bolts between existing shaftflanges Requires no machining Simple to install Simple to periodically checkalignment Wide range of stock Accepts propeller thrust Impervious to salt water,diesel and lubrication oils Fast installation time Electrical continuityavailable Worldwide availability Competitively pricedR & D Marine has developed a wide range of competitively priced FlexibleCouplings to fit all major R & D Flexible Couplings reduce engine noise, vibration transmission andare designed to accept propeller thrust, a separate thrust bearing and bulk headare not required. The Couplings are made from a polyester elastomer which is not affected by saltwater, diesel and lubrication electrical continuity is required an earthing connector can be fitted in thecentre of most Flexible is quick and easy as the R & D coupling requires no machining andcomes supplied with bolts to connect between the two existing Shaft alignment on installation and during service checks is quick and easyusing the red cone headed are available ex-stock and worldwide through our distribution WorksClothall RoadBaldockHertfordshireEnglandSG7 6 PDContact Us By:Tel: +44 (0)1462 892391 Fax: +44 (0)1462 896448 Web Site: mail: CONNECTORS R & D Marine Earthing Connector consists of a silver impregnated rubber strip, which when fitted through the axis of the couplingbetween the two fail safe straps gives electrical continuity.

6 The contoured disc givesclearance for bolt heads, and is able to flex freely to take up any temporary misalignment of the engine and Shaft , due to flexing of the boat structure or theengine moving on its rubber vibration isolation mountings. Forward thrust is taken in compression on the disc between the two half Couplings and reverse thrustis taken again in compression on the disc between the two fail safe straps. In the unlikely event of a disc failure, the steel straps make the coupling fail safe andensure drive is maintained in both forward and as standard are non-conducting but we can supply a silver impregnated rubber element to fit in the centre of the coupling between the twofail safe straps to give continuity if calculate Power of coupling Power of Engine x Reduction Ratio x 100 = HP/100rpmEngine Speed150 x 2 x 100 = 12 HP/100 rpm coupling Required 910-009 Borg Warner2500 ALLISONM259" Flange910-046 BORG WARNER4" Flange910-001, 910-004, 910-01470C 71C500 100015005" Flange910-009(BW) 910-029,910-044(BW)
