This invention discloses a gear tooth accuracy testing device and method, relating to gear processing and production technology. The device utilizes conventional mechanical components, making it easy to manufacture and maintain, and suitable for rapid sampling inspection on the production floor. The auxiliary mechanisms, particularly the cage and adjusting components, can accommodate multiple sets of measuring columns.

This facilitates data recording while effectively eliminating the influence of gear installation eccentricity, journal runout, and addendum runout on the measurement results, resulting in a more accurate reflection of the tooth groove's inherent deviation.
