Maximize your throughputs with proven high-speed gear drive solutions from Philadelphia Gear. We combine world-class engineering, long-term reliability, and a highly competitive initial cost to provide the industry’s leading gear drive design, manufacture, and repair.
As a founding member of the American Gear Manufacturer’s Association (AGMA) and a current member of the American Petroleum Institute (API), Philadelphia Gear leverages the unique skills and capabilities needed to match the extreme conditions of your most demanding applications.
WHAT GOES INTO A SUPERIOR HIGH-SPEED GEAR DRIVE?
For over 130 years, Philadelphia Gear has engineered and perfected a range of features to keep units performing at their peak efficiency while running at full capacity.
- Housings: Rugged design adds strength and rigidity, maintaining precise gear and bearing alignment. Custom cast or fabricated housings available.
- Bearings: Split, steel-backed, Babbitt-lined precision journal bearings have thrust faces engineered to account for axial load.
- Shafts: Machined from heat-treated, high-quality alloy steel. Oversized to maintain gear alignment and protect from overload.
- Gears: Designed, manufactured, and assembled with cutting-edge technology; through-hardened, or case carburized steel forgings; precision-hobbed and ground for accuracy and superior finish
- Pinions: Integral with shafts, precision-hobbed and ground; carburized or through-hardened versions per specifications
- Seals: Aluminum labyrinth seals prevent shaft leaks at extreme temperatures
- Dynamically balanced: Assures all rotating elements run smoothly at high speed
- API/instrumentation: Built to API standards as required, with a wide range of instrumentation options to satisfy any application requirements
HIGHER SPEEDS. HARSHER ENVIRONMENTS.
The same number of cycles a conventional gear drive would experience in years, a high-speed gear drive can experience in mere days. And often, these high-speed gear drives are placed in harsh environments — from offshore in the North Sea to the frozen tundras of Canada.
Keep gearing failure at bay with Philadelphia Gear. Our experts build and integrate each element of our gear drives to withstand your application’s demands. In fact, we currently have units successfully operating with ratings up to 80,000 horsepower, shaft speeds up to 70,000 revolutions per minute, and pitch line velocities exceeding 35,000 feet per minute.
THOROUGHLY INSPECTED - AND GUARANTEED
Rest easy knowing your high-speed drive has been tested as full speed under variable conditions. We use sophisticated instrumentation to analyze vibrations, sound levels, lubrication, and gear mesh frequencies.
Our experts also monitor shaft vibrations to ensure acceptable, sound, oil, and bearing temperature levels, in addition to checking and documenting gear tooth patterns. And to ensure your equipment performs as designed, Philadelphia Gear backs each gear drive with an industry-leading five-year warranty.
