R&D Drivetrain Damper Drive Plates at Fisheries Supply

R&D Drivetrain is a leading manufacturer of marine engine parts and accessories, including flexible shaft couplings, engine mounts, split shaft couplings, and damper plates. These products are designed to reduce vibration and noise, protect the drivetrain, and ensure the smooth operation of marine engines.

What are Damper Drive Plates?

Damper drive plates, also known as damper plates or drive plates, are an essential component of marine engines. Damper drive plates are designed to prevent gearbox rattle, protect the drivetrain, reduce noise, and ensure the smooth operation of marine engines. Damper plates are typically made of a flexible polyurethane element, which is stiff enough to transmit engine power while remaining flexible enough to isolate vibration.

Types of Damper Drive Plates

R and D Drivetrain drive plate offers three types of damper drive plates for different applications:

• Linear Elements: These are designed for general applications and provide a linear dampening of the torque applied to the system with up to a 3-degree deflection of the element.
• Hammer Head Elements: These are designed for general use where motoring at low RPMs is common and provide a two-stage dampening of the torque with up to a 9-degree deflection of the element.
• High Deflection Elements: These have a softer element designed for use in vessels where low RPM engine use is the norm, as in work boats or pleasure boats. They give three distinct stages of dampening with up to a 30-degree deflection of the element.

Selection of Damper Drive Plates

The selection of damper drive plates is a complex process that requires knowledge. To choose the right damper plate, consider the following factors:

• Engine Specifications: The manufacturer of the engine, maximum horsepower, maximum engine RPM, and number of cylinders are essential factors in selecting the right damper plate.
• Gearbox Specifications: The manufacturer of the gearbox, model number, gear reduction, and input spline details are crucial for choosing the appropriate damper plate.
• Back Plate Specifications: The outside diameter of the back plate, number of fastener holes, diameter of holes, and pitch circle diameter of holes are essential for selecting the correct damper plate.

Benefits of R&D Drivetrain Damper Drive Plates

R&D Drivetrain's damper drive plates offer several benefits, including:

• Reduced Gear Noise: By preventing gearbox rattle at low engine speeds, these plates allow an engine to operate through its entire RPM range without causing gear noise.
• Protection of Drivetrain: Damper drive plates help protect the drivetrain by reducing gear wear and damage caused by gear chatter or rattle at low RPMs.
• Fail-Safe Design: The plates are designed to fail in a safe mode, ensuring that the boat can continue to function even if the flexible element fails. This fail safe damper plates feature is reassuring.
• No Springs to Rust or Fret: Unlike traditional spring-type dampers, R&D Drivetrain's damper plates do not require springs, which can rust over time.

Fisheries Supply carries a variety of R&D drivetrain Yanmar engine mounts.
