A method for the determination of optimal tooth modifications in spiral bevel gears based on improved load distribution, minimized tooth root stresses and reduced transmission errors is presented. The modifications areintroduced intothepinion tooth surfacebythevariation ofmachinetool settings in...

The paper pertains to analytical study of the major reasons that cause tooth failure in gearing having small teeth number. Below, gearswith small teeth numberarereferred to STN--gears. Fortheanalysisofgeartooth failure, tooth contact stresses, and the combined contact/shear stresses...

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...
