This article summarizes results of research programs on RCF strength of wrought steels and PM steels.

In order to grind gears burn-free and as productively as possible, a better understanding of the process is required.

The palette of thermoplastic materials for gears has grown rapidly, as have the applications themselves. Designers need to be aware of key properties and attributes in selecting the right material.

The two-flank roll test measures kickout (tooth-to-tooth composite error) and tooth thickness. In this article, it will be shown that measured values vary with the number of teeth on the master gear.

This article describes a root fillet form calculating method for a helical gear generated with a shaper cutter.

Due to its economical efficiency, the gear shaving process is a widely used process for soft finishing of gears. A simulation technique allows optimization of the process.

A study was conducted to isolate the influence of pre-rough machine processing on final dimensional distortion.

Molded plastic gears have very little in common with machined gears other than the fact that both use the involute for conjugate action.

A main limiting factor in extending the use of hard coatings to machine component application is the lack of knowledge about how these inert coatings perform under lubricated conditions using today's lubricants.

This article presents a new spur gear 20-degree design that works interchangeably with the standard 20-degree system and achieves increased tooth bending strength and hence load carrying capacity.
