AGMA's Gear Expo is now the Motion + Power Technology Expo. Over three action-packed days, end-users can shop the latest technology, gear products, and services, and compare benefits side-by-side. Prominent exhibitors will conduct demos and host information-rich seminars as well as offer-up technical expertise.
Does the definition of specific sliding mean the same between ISO 21771:2007 and AGMA 917-B97? In ISO, specific sliding is the ratio of the sliding speed to the speed of a transverse profile in the direction of the tangent to the profile. In AGMA, specific sliding is ratio of gear tooth sliding velocity to its rolling velocity.
I need help determining the diametral pitch needed to achieve the closest
center-to-center distance for 2 spur gears. The 1st gear is a 34-tooth and
the 2nd gear is a 28-tooth. The center-to-center distance between the
gears needs to be as close to 2 1/8" as possible.
Asymmetric tooth gears and their rating are not described by existing gear design standards. Presented is a rating approach for asymmetric tooth gears by their bending and contact stress levels, in comparison with symmetric tooth gears, whose rating are defined by standards. This approach applies finite element analysis (FEA) for bending stress definition and the Hertzian equation for contact stress definition. It defines equivalency factors for
practical asymmetric tooth gear design and rating. This paper illustrates the rating of asymmetric tooth gears with
numerical examples.

This paper provides a mathematical framework and its implementation for calculating the tooth geometry of
arbitrary gear types, based on the basic law of gear kinematics. The rack or gear geometry can be generated
in two different ways: by calculating the conjugate geometry and the line of contact of a gear to the given
geometric shape of a known geometry (e.g., a cutting hob), or by prescribing the surface of action of two gears in contact and calculating the correspondent flank shapes.
