R&D f/4" Yanmar Flexible Shaft Coupling - 3HP/100RPM Capacity Marine Hardware

Flexible Shaft Coupling for Yanmar 4" - Capacity 3HP/100RPM

R&D flexible couplings are made from a profiled flexible disc molded in a new type of strong but durable polyurethane. resilient disc profile provides clearance for bolt heads, and is able to flex freely to compensate for any temporary misalignment of the motor and shaft, due to flexing of the boat structure or movement of the motor on its mounts. rubber vibration isolation The forward thrust is taken in compression on the disc between the two coupling halves and the reverse thrust is taken in compression on the disc between the two failure straps. probable of disc failure, the steel straps ensure the security of the coupling and guarantee that the drive is held in forward and reverse br>
To calculate the coupling power. required:
Engine horsepower _{x Reduction ratio x 100 = HP/100RPM}
Engine speed

Example:
Ford 150 HP at 2500 rpm with Borg Warner Velvet Drive 72C 2:1 reduction ratio
Engine power is 150 hp, maximum rated speed is 2500, reduction ratio is 2 :1
150/2500 transmission output and shaft coupling. It is designed to protect a boat's transmission. The unit will reduce vibration, compensate for some misalignments, isolate the shaft and absorb shock loads.

The flex disc is machined from a resilient and durable polyurethane. It allows the unit to flex, absorbing vibration and temporary misalignment of the shaft and motor due to motor movement or flexing of the vessel structure.

The diThe polyurethane skeg is supported by two metal compression straps, one on each side of the flexible connector. These metal straps keep the system in constant compression whether the transmission is in forward or reverse. This feature significantly extends the life of the system.

The R&D Marine Flexible Coupling will also absorb shock resulting from changes in speed or the propeller colliding with a submerged object. The polyurethane disc deforms under light shock loads and is designed to be sacrificial under heavy shock loads, saving costly transmission repairs. If the disc is destroyed due to a massive shock load, the metal compression straps keep the coupling intact, ensuring that the drive system is functional in both forward and reverse directions.

Why R&D Marine Shaft couplingss flexible?

Polyurethane flange creates a flexible barrier to reduce drivetrain noise and vibration to quiet your drivetrain
Absorbs transmission shocks caused by propeller and high-speed gear changes. This helps reduce and avoid costly damage to the drivetrain
Fail-safe design, forward and reverse thrusts are taken in compression by the steel straps, resulting in a durable design even in extreme conditions

R&D Marine has developed a wide variety of flexible fittings at reasonable prices to suit all major installations. The developed flexible coupling can reduce motor noise and vibration. -f-4

R&D f/4" Yanmar Flexible Shaft Coupling - 3HP/100RPM Capacity Product Description Flexible Shaft Coupling for Yanmar 4" - 3HP/100RPM Capacity

R&D Flexible Couplings are made from a contoured flexible disc molded in a new type of strong yet resilient polyurethane. The profiled disc provides space for bolt heads and is capable of flexing freely to compensate for any temporary misalignment of the motor and shaft, due to flexing of the boat structure or movement of the motor on its insulation mounts rubber vibrations. The forward thrust is taken in compression on the disc between the two half-couplings and the reverse thrust is taken in compression on the disc between the two breaking straps. In the unlikely event of disc failure, the steel straps keep the coupling secure and ensure the drive stays running forward and runningrear.

To calculate the required coupling horsepower:
Engine horsepower _{x Reduction ratio x 100 = HP/100RPM}
Engine speed

Example:
Ford 150 HP at 2500 rpm with Borg Warner Velvet Drive 72C 2:1 reduction ratio
Engine power is 150 HP, maximum rated speed is 2500, Reduction ratio is 2:1
150/2500 X 2 x 100 = 12 HP per 100 rpm
L The required coupling is 910-009
