| Summary: | On the basis of space curve meshing equation of line gear, geometric characteristics of a driven contact curve for a driven line gear are deduced from a given driving contact curve of a driving line gear for the skew line gear (SLG) mechanism. The geometric interference is analyzed between the driving and driven line teeth of the SLG pair at the non-meshing point during the mesh process. Afterwards, a supplementary design criterion is proposed for proofing against geometric interference. The selection criteria and calculation formulae of geometric parameters for the SLG pair are subsequently derived and an experiment was carried out to test their kinematic performance. The experimental result shows that the proposed methods serve as a convenient and reasonable design tool for the SLG pair in practical application.
