The optimal design of standard gearsets [PDF]
, 1983 A design procedure for sizing standard involute spur gearsets is presented. The procedure is applied to find the optimal design for two examples - an external gear mesh with a ratio of 5:1 and an internal gear mesh with a ratio of 5:1.

DEFORMATION AND STIFFNESS OF SPUR GEAR TEETH AND THEIR INFLUENCE ON GEAR NOISE
Scientific Journal of Silesian University of Technology. Series Transport, 2015 Gear teeth are deformed due to the load. The deformation of gear teeth is causing some negative as well as positive effects. A tooth has a complex shape and due to the complex shape of the teeth, a theoretical determination of the deformation is difficult.
