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

Numerical analysis of meshing heating of involute spur gear

Journal of Physics: Conference Series, 2021
Abstract Involute spur gears generate heat due to tooth surface meshing friction. Excessive temperature rising affects transmission accuracy and reduces work reliability.. By establishing the normalized coordinates of the meshing curve and based on the frictional heat generation theory, the mathematical analysis model of the meshing ...

Implementation of the Spur Involute Gear Model on Modelica [PDF]

Linköping Electronic Conference Proceedings, 2011
A procedure to build up a dynamical model of the gearbox with spur involute mesh is being described. The main attention is paid to the design technology of the cylindrical bodies elastic contact models. To track geometry of contact implicit equations of algebraic/transcendental or differential-algebraic type are being used.
