Factors Affecting Primary Machining Accuracy of Internal Gears

Internal gear drives are widely used in mechanical driving devices.Limited by machining method,the machining accuracy of internal gear has a direct effect on the quality of gear drive.Taking the machining of internal gear with straight teeth for example,the factors affecting on the machining accuracy of internal gear were analyzed from process system,and the measures of improving the machining accuracy of internal gear were proposed in this paper.
