Improving the quality of manufacture of the differential pinion gears through the integrated application of statistical methods of quality management

Abstract

© Published under licence by IOP Publishing Ltd. An approach is proposed to ensure a stable spot size in the interfaces of the satellites with the central gear. Characteristics are proposed for estimating the position of the contact patch on the lateral surface of the tooth The characteristics of the contact patch after circular broaching were analyzed using various statistical methods. The dependence of the characteristics and position of the contact patch on the tooth surface on a number of factors has been revealed. Proposed measures for their stabilization.
