Abstract：[Objective]A study was conducted to address the unclear variation patterns of meshing characteristics in linear conjugate internal gear pairs.[Methods]Based on the parametric model of linear conjugate internal gear pairs,theoretical expressions for pressure angle,sliding ratio,and induced normal curvature were derived.By comparing with involute internal gear pairs,the meshing characteristics of the gear pair were elucidated.Subsequently,static stress simulations of the gear pair were conducted to analyze its force distribution patterns.Furthermore,the influence of design parameters such as tooth number,tooth profile angle,and reference circle tooth thickness coefficient on meshing characteristics was examined.[Results]The research reveals the variation patterns of meshing characteristics in linear conjugate internal gear pairs,and the findings contribute to refining the design framework for such gear pairs.
