Contact pressure and load distribution are key indices used in the performance evaluation of
spiral bevel gears, and their calculation accuracy and efficiency continue to be the focus of …

The computerized design of curvilinear cylindrical gears based on the active design of the
meshing line function is presented. The parametric equations of their meshing line functions …

Face-milling cutting method, widely used in the generation of spiral bevel gear, can also be
applied to cylindrical gear fabrication. This paper, generalizing the method to non-circular …

Spur gears with tip relief can effectively improve transmission performance, and accurate
determination of their tooth surface contact stress (TSCS) can provide guidance for structure …

Misalignment errors (MEs) in multiple degrees of freedom (multi-DOFs) along gear pair axis
are unavoidable under actual working conditions. These MEs lead to changes in tooth …

Contact fatigue is one of the main failure modes of gears. Gear contact fatigue reliability test
is not only an important way to understand the gear capacity, but also the data foundation in …

Stiffness excitation is one of the important excitations for the variable hyperbolic circular-arc-
tooth-trace (VH-CATT) cylindrical gear system. Accurate calculation of the gear meshing …

To improve the bearing capacity and provide the mathematical model basis for vibration and
noise reduction of the variable hyperbolic circular-arc-tooth-trace (VH-CATT) cylindrical …

Sažetak To reconstruct the tooth surface of a circular arc tooth trace cylindrical gear (CATT
gear), one needs to create an accurate 3D model and investigate geometric features of the …

There are two types of curvilinear cylindrical gear drives: those with point contact and those
with line contact. In this paper, a mathematical model, tooth contact analysis and stress …
