This paper mainly discusses that in the new system of national standards of cylindrical gear accuracy,radial run-out will not be tested as mandatory inspection items.In addition,the variable combination of the radial run-out and the base tangent length will also not served as the reason for the controlling of gear precision movement.From the perspective of theory and practice,this paper also elaborates the significance in the designing of the gear precision and the machining of the gear cutting as well as the application of radial run-out.Therefore,it is concluded that in the process of the im...
