Vibratech Silicone Crankshaft Damper

CRANKSHAFT DAMPERS

Engine manufacturers are challenged to deliver emissions-compliant, quieter and more fuel-efficient powertrains without sacrificing performance and reliability. The use of sophisticated turbochargers, high pressure fuel injection and elevated mean effective pressure sets up an even greater torsional vibration force on the crankshaft. A quality viscous style crankshaft damper is an essential component to maintain durability standards.

For over 70 years, Vibratech TVD (formerly Houdaille) has delivered the broadest industry leading experience in viscous damper design and development.  ISO 9001:2015 Design & Development certified.

CASE STUDY HIGHLIGHTS

OFF-HIGHWAY

Global manufacturer of off-highway equipment on verge of loosing customer because of major torsional vibration problems originating from elastomeric damper failing during operating duty. Manufacturer sought viscous damper solution from Vibratech TVD for improved durability and reliability. Vibratech TVD was able to analyze, engineer and manufacture a solution within a matter of weeks, thus helping to save the customer for the manufacturer.

Impressed with the benefits and understanding the limits of retrofitting, the same manufacturer then contracted with Vibratech TVD to develop viscous dampers in conjunction with their Tier 4 engine development.

DEFENSE

Vibratech TVD contracted by major manufacturer of military vehicles to develop and manufacture viscous damper as an upgrade from elastomeric damper causing potential engine failures during field operations. Newly developed diesel engine equipped with Vibratech TVD torsional viscous damper successfully passed NATO validation testing.

MOTORSPORTS

Race engine developer and manufacturer associated with major OEM racing division solicited Vibratech TVD to optimize a small diameter viscous damper at 10,000rpm for a naturally aspirated in-line four application.  Vibratech viscous silicone damper to replace current elastomeric design for improved durability and performance.  New Vibratech TVD developed under the Fluidampr brand exceeded validation testing and was approved SFI 18.1 for use in professional motorsports.

SPRINGVILLE, NY [April 23, 2020] – Vibratech TVD announces the general release of a Severe Duty crankshaft damper for Cummins ISX / X15 engines.  Over-the-road truck operators and heavy duty diesel technicians requested the product to be developed after experiencing crankshaft failure and front gear noise under severe conditions while using the OE vibration damper.

The Vibratech TVD Severe Duty damper is more robust than the traditional Vibratech TVD Heavy Duty standard ISX / X15 replacement.  Diameter remains 14-3/4” while damping mass is increased 37% to 54.7 lbs.  Damper durability is also improved for continuous operations in high ambient temperatures above 100oF / 38oC.

Vibratech TVD recommends the Severe Duty damper if experiencing front gear noise, power output above 600 hp, and/or in long haul trucks with multiple trailers.  Other applications may include high temperature environments, logging, mining and construction.

OEM DAMPER DESIGN & DEVELOPMENT:

Vibratech TVD’s expert concentration is OEM damper design & development for the powertrains that move the global economy. From conception through production, we provide personal attention and flexibility to efficiently assist engineering teams exceed their goals.

For the past 70 years, Vibratech TVD viscous dampers have been the commercially proven method to deliver reliable powertrain durability.  Built into every Vibratech TVD torsional viscous damper is expert torsional vibration analysis, design integration, engineering, and demanding product validation.

The viscous damper has evolved from crankshaft applications to include camshafts, drivelines, and hybrid or full electric drives. To assist in overall cost reductions, Vibratech TVD engineering and precision CNC machining can provide for the integration of pulleys, gears and timing wheels into the outer housing of the damper.

Vibratech TVD solicited to participate in engineering exercise to reducing weight, cost and increase longevity of damper currently used on major global over-the-road engine and vehicle manufacturer.

AVIATION

Light aircraft engine manufacturer sought Vibratech TVD to improve durability of current starter shaft viscous damper.  Vibratech TVD analyzed design and developed proprietary non-metallic internal bearing.  New viscous damper improved quality and successfully passed FAA validation testing.  Vibratech TVD was awarded production contract from manufacturer.

Driveline Dampers:

Rotating shafts present a NVH challenge.  Speed fluctuations create torsional vibration that can damage downstream components or create uncomfortable noise conditions.  To resolve concerns manufacturers turn to Vibratech TVD for our expert torsional vibration analysis, design integration, engineering and demanding product validation.  ISO 9001:2015 Design & Development certified.

Examples of where OEM manufacturers have partnered with us include:

  • Hybrid transmission drives on buses.
  • Fire engine piston driven water pump shafts.
  • PTO shaft accessories.
  • Auxiliary starter shaft drive gears.

In each of these examples Vibratech TVD developed a tuned viscous damper specific to the driveline application with the goal of improving durability and overall quality. A narrow frequency band coverage with a viscous damper is achieved through our ability to fine tune and hold precision machining tolerances in combination with proprietary silicone selection.

BENEFITS OF A VIBRATECH TVD VISCOUS DRIVELINE DAMPER

  • Tuned for optimum protection in a narrow frequency band of a single order.
  • Lasts the life of the driveline.
  • Suitable for harsh outdoor environments.

MASS TRANSIT

Vibratech TVD was approached by a major manufacturer of mass transit buses to analyze, test, engineer and manufacture viscous dampers to eliminate driveline torsional vibrations causing unacceptable NVH throughout the cabin.

AVIATION

Light aircraft engine manufacturer sought Vibratech TVD to improve durability of current starter shaft viscous damper.  Vibratech TVD analyzed, then designed and developed a proprietary non-metallic internal bearing.  New viscous damper improved quality and successfully passed FAA validation testing.  Vibratech TVD was awarded production contract from manufacturer.

Hybrid Dampers:

Full-electric and hybrid drive vehicles face new torsional vibration challenges.  Instant full-torque induction creates stress on a driveshaft and induces unwanted NVH from backlash against the drive gears.  Incorporating a torsional viscous hybrid drive damper is a cost-effective, long term solution.

Vibratech TVD has collaborated with leading world transit bus manufacturers to resolve NVH through developing optimized narrow frequency driveline dampers.  As more passenger and off-highway vehicles adopt the efficiency of hybrid and full-electric drives, Vibratech TVD is experienced and capable of adapting a driveline viscous damper to new configurations.

Vibratech TVD recommends that OEMs do not use a viscous crankshaft damper in the research and development of drivelines and rotating shafts.  The crankshaft damper may not provide optimum results.
