R & D 42ac48 damper plate outer diameter 235mm gear for BorgWarner

The 'R&D Damper' was developed to prevent gearbox rattle (gear hammer) at low engine speeds and allow engines to be used over their complete speed range. To isolate the torsional vibrations at slow speeds it is necessary to have a very soft drive connection, which must be sufficiently strong to transimt the full torque. The 'R&D Damper' meets these requirements and consists of a moulded element in a new type polyurethane which is fail safe and in the unlikely event of a flexible element failing, the drive is maintained.

Marine Damper Drive Plates Diameter 235mm for Mercedes OM636-616

Why you should buy R&D Marine Damper Drive Plates

1. Reduces gear noise
2. Allows engine to run at lower speeds
3. Back plate punched ready to install
4. Fail safe design
5. No springs to rust, solid, fret or rattle

The 'R&D Damper' was developed to prevent gearbox rattle (gear hammer) at low engine speeds and allow engines to be used over their complete speed range.

The 'R&D Damper' meets these requirements and consists of a moulded element in a new type polyurethane which is fail safe and in the unlikely event of a flexible element failing, the drive is maintained.

R&D can offer three styles of Damper Drive Plate. The loop type is suitable for most applications. in some cases the 3 stage stiffness of the Hammer Head or the High Deflection Type is more suitable on torsionally active applications.

R&D Marine has a wide range of damper elements to meet all applications from 80 to 1630 Nm.

R&D Flexible Shaft coupling 910-033

The R&D 910 Series couplings consist of a contoured flexible disc moulded in tough yet resilient new type polyurethane. The contoured disc gives clearance for the 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 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.

Marine Damper Drive Plates Diameter 235 for Mercedes OM636-616

Why you should buy R&D Flexible Couplings

1. Bolts between existing shaft flanges.
2. Requires no machining
3. Simple to install
4. Simple to periodically check alignment
5. Reduces engine noise and vibration.
6. Fail Safe

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

Couplings as standard are non-conducting but we can supply a silver impregnated rubber element to fit in the centre of the coupling between the two fail safe straps to give continuity if required.

The R&D 910 Series couplings consist of a contoured flexible disc moulded in tough yet resilient new type polyurethane. The contoured disc gives clearance for the 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 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.

The 900 series couplings use flat discs and contoured castings with a central high tensile bolt to take reverse thrust, they are also fail safe.

Python-Drive P30-R

Python-Drive features:

•     Double ended constant velocity drive shaft suitable for both Pleasure and High Performance applications.

•     Eliminates the need for exact alignment of prop shaft to gearbox.

•     Maintenance free thrust bearings.

Advantages of fitting a Python-Drive:

•     The constant velocity drive shaft guarantees a constant prop shaft speed, even when angles are unequal.

•     Propulsion thrust is isolated from the gearbox by being absorbed by the rubber mounting blocks.

•     Not only is de Python-Drive robustly constructed, it is available in both Imperial and Metric dimensions, covering prop shafts from  ¾” (19.05 mm.) up to 4” (100 mm.).

•     The thrust bearing units can be used as stand alone units, on request they can be machined to suit universal (cardan) shafts.

•     Python-Drive constant velocity drive shafts are able to take torques of up to 1,500 kgm. (appr. 14.7 kNm.).

•     Drive Shafts are available in different lengths and can be made to suit individual sizes.

•     Supplied complete with all necessary studs, bolts, washers, gearbox flange and accompanied by an easily understood installation manual.
