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 […]
Methods to Determine Form Diameter on Hobbed External Involute Gears
In custom designs of external spur or helical gears, designers generally prefer a lower form diameter for greater transverse contact […]
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 […]
