Automatically operating gear-testing device

摘要

An automatically operating testing device is specified for testing the circular pitch of toothed gears and, in a development, for simultaneously testing the deviations in concentricity of the teeth, deviations in tooth thickness and deviations in tooth spaces of these toothed gears, the circular pitch testing being performed simultaneously in one measurement cycle for right-hand and left-hand tooth profiles of the teeth, and the possibility exists of likewise using the measured values thus obtained to determine the deviations in concentricity of the teeth, deviations in tooth thickness and deviations in tooth spaces.
