Toe and Heel
In bevel gear pairs, they denote respectively the inner end of the tooth (toe, towards the cone apex) and the outer end (heel). The distribution of contact between toe and heel is critical for gear durability and noise.

Technical Gear Glossary
Definitions of the main technical terms used in motion transmission with technopolymer gears.
T
Transmissible torque
Maximum torque that a gear can transmit without exceeding admissible stress limits. Obtained from the product of the tangential force on the pitch circle and the pitch radius.
Tribology
Discipline concerned with the study of friction, wear and lubrication between surfaces in relative motion. Fundamental for predicting the service life of technopolymer gears.
