Scope: This document specifies the principle, purpose, type, method, equipment, failure criterion, procedure, data processing and test report of the involute cylindrical gear tooth root bending fatigue strength test. This document is applicable to the determination of the basic data required for the design of the bending fatigue bearing capacity of involute cylindrical gears made of steel or cast iron, and is applicable to the comparative analysis of the bending fatigue performance of gears under the conditions of different materials, different processes, and different modification methods. . Similar tests for gears made of other materials or non-involute gears can be used as a reference.
