R&D Marine Damper Drive Plates are designed to prevent gearbox rattle at low engine speeds, which allows an engine to operate through its entire RPM range. Today’s marine diesels are designed with lightweight flywheels which do not create the inertia of an older heavy flywheel. The lighter flywheels result in gear chatter or rattle at low RPM’s. This rattle translates into gear wear and damage to the drivetrain. R&D Marine Damper Plates eliminate this problem. DAMPER PLATES Reduces Gear Noise And Allows The Engine To Run At Lower Speeds
Three types of damper plates are available for different applications:
1. A “Loop” damper plate is designed for general applications. This damper provides a linear dampening of the torque with 3 degrees of deflection of the element. 2. A “Hammer Head” damper plate is designed for general use where motoring at low RPM’s is common. This damper provides a two stage dampening of the torque with 9 degrees deflection of the element. 3. A “High Deflection” damper plate is designed for use in vessels where low RPM engine use is the norm as in work boats or where gear noise is being experienced. The “HD” damper gives three distinct stages of dampening with 30 degrees deflection of the element, virtually eliminating gearbox rattle for extended use even at idle speeds. All R&D Damper Plates use a molded polyurethane element to absorb the engine torque. The fail safe design of the plate ensures that even in the unlikely event of a flexible element failure (from severe shock load), the drivetrain system would remain functional. The back plates for the R&D Marine damper plates are punched and ready to install. They can be installed within the existing space of a metal spring damper. FEATURES • Reduces gear noise • Fail safe design • Quick and easy installation
VIBRATION ISOLATION R&D Marine Damper Drive Plates reduce gear noise by preventing transmission rattle at low engine speed and allow the engine to run at lower speeds. DURABLE No springs to rust or fret. The flexible element is designed to withstand increased temperatures and is not affected by salt water, diesel or lubrication oils. WIDE RANGE OF STOCK Damper Plates to fit most engine and gearbox combinations for engines up to 800 horsepower and torque range from 60 - 1,400 ft/lbs. EASY INSTALLATION The R&D Marine Damper Drive Plate requires no machining and is ready to bolt to the flywheel.
Many marine engines are fitted with a spring type damper plate. Most spring plates only provide 3 degrees of deflection. Also, steel springs will tend to corrode in a marine environment.
The drive, or damper plate, as it is often called, bolts to the engine flywheel and connects the engine to the transmission/gearbox's splined shaft. The R&D Marine Damper Plates use a special element and are designed to load at lower RPM's and prevent the input spline from backlashing to reduce spline gear wear.
