Leveraging the complementary strengths of orbitless and planetary drives
An orbitless drive is a novel, fixed-ratio, epicyclic drive that includes a second carrier in place of a ring gear. […]
Root cause for noise excitation in geometrically-accurate (perfect) parallel-axes gearing
Gears are extensively used to transmit a rotation from a driving shaft to a driven shaft. Depending on the gear […]
Application of Finite Element Analysis for the Strain Wave Gear Tooth Surfaces Design and Modification
This paper represents the application of finite element analysis for the strain wave gear with modified conjugate tooth surfaces. The […]
Lean Heat Treatment for Distortion Control
Controlling distortion is of key importance during the case hardening process for the production of gear components. By effective control […]
An Animated Approach to Plotting Profiles
Trochoid Spiral (TS) and Epitrochoidal Spiral (ETS) curves and special flash animations were developed by the author in 2004 and […]
Profile Relief and Noise Excitation in Helical Gears
Gear noise results from the gear mesh dynamic forces that are transmitted through the support shafts and bearings to the […]
Are Energy Answers Blowing in the Wind?
Renewable Wind Energy Production (RWEP) in Wyoming has been related to three locations in the state: Cheyenne, Arlington, and Evanston. […]
Polyglycols for Lubricating Large Gear Drives
Introduction In modern-day gear technology, the lube oil used is an important element of the gear’s overall design. Increasingly stringent […]
Determining the Source of Gear Whine Noise
Gear whine noise, particularly in consumer products such as motor vehicles and appliances, is an important and annoying problem. This […]
The Simultaneous Dual Frequency Method of Inductive Gear Hardening
Inductive surface hardening is an attempt to harden only the surface of a structure without affecting the inner portions of […]
