Early results from testing conducted by Genesis Partners LP have raised questions concerning the role of gear action with the appearance of micropitting as well as surface fatigue (macropitting). Comparisons between similar gearsets with the same loads,...

Involute spline couplings are used to transmit torque from a shaft to a gear hub or other rotating component. External gear teeth on the shaft engage an equal number of internal teeth in the hub. Because multiple...

An offshore jack-up driling rig is a barge upon which a driling platform is placed. The barge has legs which can be lowered to the sea floor to support the rig. Then the barge can be“jacked-up' out...

In recent years gearbox technology has advanced and Original Equipment Manufacturers (OEM) have required gear oils to meet the lubrication requirements of these new designs. Modern gearboxes operate under severe conditions and maintain their reliability to ensure...

QuesTek Innovations LLC is applying its Materials by Design⑧computational design technology to develop a new class of high strength, secondary hardening gear steels that are optimized for high-temperature, low-pressure (ie., vacuum) carburization. The alloys offer three different...

Powder metal (P/M) process is making inroads in automotive transmission applications because of substantially lower cost of P/M steel components for high volume production as compared to wrought or forged steel parts. Although P/M gears are increasingly...

Micropitting has become a major concern in certain classes of industrial gear applications, especially wind power and other relatively highly loaded somewhat slow speed applications, where carburized gears are used to facilitate maximum load capacity in a...

Any transmission design requires meticulous attention to detail including gear engineering, required performance, and manufacturing methodology. Plastic geared transmissions are no different in many ways than metal; however they do require a unique knowledge of the materials,...

Gear engineers have long recognized the importance of considering system factors when analyzing a single pair of gears in mesh. These factors include important considerations such as load sharing in multi-mesh geartrains and bearing clearances, in addition...

A recent trend has been a movement to more user friendly products in the mechanical power transmission industry. One of these more user friendly styles is a high horsepower, right angle shaft mounted drive designed to minimize...
