Root Fillet Optimization of Gears with Asymmetric Teeth

This paper provides an analysis of the benefits of optimizing the tooth root fillet of thin rim planet gears with asymmetric teeth.

By Dr. A.L. Kapelevich and Dr. Y.V. Shekhtman The Direct Gear Design method optimizes various parameters and elements of gear tooth geometry to achieve the required gear drive performance. One such critical element of the tooth profile is the root fillet. Its optimization by means of Direct Gear Design provides the ultimate bending stress minimization. […]

Improving the Friction Power of Gears and Bearings

Proper lubrication can extend the overall fatigue life of gears by a factor of 2.6.

A machine that runs endlessly without any wear and frictional losses — who wouldn’t dream of that? Unfortunately, such a machine does not exist yet. However classic car fans know that through solid technology and ongoing service, cars can even outlast their owners. However, this does not happen with machinery of all industries. In the […]
