Micropitting and pitting are typical fatigue failures, which occur on the flanks of highly stressed, case carburized gears. Both failure modes are strongly influenced by the lubricating conditions and lubricant properties. Standardized test methods with defined test...

Modern automated machineries are increasingly using flexible high dynamic servomotors because of their ability to speed up and flexibly automate complex motions these machineries need to perform. Planetary gearheads are used frequently in conjunction with servomotors to...

Superfinishing is atechnologythatpublic literature suggests to have potential forincreased powerdensity. A study was conducted characterize this technologies benefit to bending fatigue. Two sample groups were created, one from AMS6265, and the second from AMS6265 with super finishing....

With increasing requirements, many conveyor systems utilize dual drive arrangements to increase output.Dual drives can provide an economical solution byutilizing smaller, more efficient, system designs. However,multiple drive conveyors must proportion the load between drives and load sharing...

Historically, catalog gear drives have been designed with 5000 hours of L1 0 bearing life at service factor 1 .0 power. Advances in bearing analysis methods have brought new considerations to the design and selection process. The...

Thispaperdescribes arootfilletform calculating method forahelical geargenerated with ashapercutter. The shapercutterconsidered has an involute main profile and elliptical cutteredge in the transverse plane. Since the fillet profile cannot be determined with closed form equations, a Newton’s approximation method...

A model to predict friction--related mechanical efficiency losses of hypoid gear pairs is proposed, which combines a commercial available finite element based gear contact analysis model and a friction coefficient model with a mechanical efficiency formulation. The...

While face milled hypoid gears have been widely studied, about face hobbed ones only veryfewstudies have been developed. Aim of this paperis just to propose an accurate tool forcomputerized design of face hobbed hypoid gears. Firstly, amathematical...

Today, the motor vehicle market is focusing on ”lubed for life” differentials requiring no service for the life ofthe vehicle. Still, differentials are prone to develop problems ofone sort oranother since they are used to transmit aheavy...
