Abstract

Provided is an internal meshing cylindrical gear pair with a constant meshing characteristics constructed tooth pair. The internal meshing cylindrical gear pair with a constructed tooth pair includes an external cylindrical gear with a constructed tooth pair and an internal cylindrical gear with a constructed tooth pair based on conjugate curves. In the present disclosure, normal tooth profile curves of the external cylindrical gear with a constructed tooth pair and the internal cylindrical gear with a constructed tooth pair are continuous combined curves with the same curve shape, which facilitates machining by the same cutter. A common normal at an inflection point or a tangent point of the continuous combined curve passes through a pitch point of the gear pair, and a position of the inflection point or the tangent point can be adjusted as required, so as to adjust a sliding ratio of the gear pair.
