Conical involute gears (beveloids) are used in transmissions with intersecting or skewed axes and for backlash-free transmissions with parallel axes.

Review of "Gigacycle Fatigue in Mechanical Practice," by Claude Bathias and Paul C. Paris

Ten years ago, most mainstream gear manufacturers didn't even consider plastics as an option, especially in higher power applications.

Bevel gear manufacturers live in one of two camps: the face hobbing/lapping camp, and the face milling/grinding camp.

Wait a minute, we don't measure pitch diameter. We're sometimes asked to measure it by customers, though, especially ones with older drawings.

Guidelines are insurance against mistakes in the often detailed work of gear manufacturing. Gear engineers, after all, can't know all the steps for all the processes used in their factories.

The objective of this research is to develop a new lapping process that can efficiently make tooth flanks of hardened steel gears smooth as a mirror.

This article reviews mathematical models for individual components associated with power losses, such as windage, churning, sliding and rolling friction losses.

The gear designer needs to know how to determine an appropriate case depth for a gear application in order to guarantee the required load capacity.

Aachen has long been the center of European gear research.
