The Kinematics of Crossed Helical Gears
Journal of Mechanical Design, 1982A study is made of the motion of crossed helical gears. Exact expressions are derived for the position of the contact point on each gear and for the sliding velocity, both as functions of gear position. It is shown how to calculate the angular positions of each gear at the beginning and end of contact, and hence the contact ratio.

Fine Blanking of Helical Gears
2015Fine blanking is a well-established process for the production of near net shape components with high quality. The produced parts are characterized by a smooth sheared edge up to 100 %, excellent surface properties with good flatness and little burr as well as close tolerances for near net shape manufacturing. These process characteristics are suitable

Noise of Involute Helical Gears
Journal of Engineering for Industry, 1969The problem of involute helical gear noise is studied by running a pair of 6 DP gears in a power circulating rig inside an anechoic room. More than 3500 magnetic tape recordings were taken and analyzed, for gears running at different speeds and transmitting different loads.

SAE Technical Paper Series, 1984
<div class="htmlview paragraph">The purpose of this article is to provide the design formulas and acceptable stress levels so that calculations of the gear tooth geometry, surface compressive, and bending stresses at which the gears will operate in a known application can be made. It will be necessary to know the complete gear information for all
