Improving the wear resistance of 3D printed spur gears through a free-form tooth flank optimization process [PDF]

MATEC Web of Conferences, 2023
Involute gears have traditionally been the preferred choice for gear transmission systems due to their simplicity and interchangeability. However, there are applications where they do not provide the most durable and efficient solution. While the cost of

A novel tooth tip relief method for reducing micro-pitting of spur gears

Advances in Mechanical Engineering, 2021
Micro-pitting is a common fatigue failure mode of spur gears. To reduce it, this paper proposes a novel tooth tip relief method. Gear meshing simulation is firstly performed considering the actual contact path, showing that there are four Hertz contact ...

Tooth contact analysis of spur gears. Part 1-SAM analysis of standard gears

MATEC Web of Conferences, 2017
The involute gears are sensitive to the misalignment of their axes which determines transmission errors and perturbations of pressures distributions along the tooth flank. The concentrated contacts in gears are no longer as Hertz type.
