Calculation methods of spur and helical gears for preliminary designs or standardization
purposes available in technical literature use simple equations given by the linear theory of …

In this paper, an approach for mesh generation of gear drives at any meshing position is
presented and an automatic modeling program for tooth mesh analysis is developed. Based …

A “slice method” is adopted to calculate the time-varying mesh stiffness (TVMS) of helical
gear pairs, where the tooth is divided into many individual sliced spur gears along the tooth …

Gear whine noise has attracted increasing attention from researchers in both the academe
and the industry over the past two decades. The wide range of research topics demonstrates …

An analytical approach for stress analysis of gear drives with localized bearing contact
based on the Hertz theory is proposed. The proposed approach provides a complete and …

A three-dimensional lumped-parameter model for a pair of helical gears is developed and
shown to be equivalent to an arbitrary tooth contact force distribution. The nonlinearity of the …

Form grinding is the most popular finishing process for large-size gear because of its high
accuracy, efficiency, and flexibility in tooth flank modification. Theoretically, this tooth flank …

A version of a worm gear drive with improved bearing contact, reduced level of transmission
errors and lessened sensitivity to errors of alignment is proposed. Unlike the existing …

Since the intrinsic limitations of FEM (Finite element method) and lumped-mass method, we
derive the formula of 8-node hexahedral element based on VFIFE (vector form intrinsic finite …

Gear transmission system fault diagnosis is crucial for the reliability and safety of industrial
machinery. The combination of mathematical signal processing methods with deep learning …
