In literature the determination of the contact ratio of crossed helical gear pairs is presented up to now only in general form. Especially under consideration of the relatively large tolerances occurring in mass production calculation measures needed for the design are lacking which consider the ...
LARGE CONTACT RATIO, INNER ENGAGEMENT CYCLOIDAL GEAR STRUCTUREA large contact ratio, inner engagement cycloidal gear structure, comprising an inner cycloidal gear (1) and an outer cycloidal gear (2) disposed inside the inner cycloidal gear (1) and configured to engage with the inner cycloidal gear...
high-contact-ratio gear; tooth spalling; meshing stiffness; nonlinear dynamic behavior 1. Introduction The contact ratio is an important index to indicate the smoothness and the uniformity of the gear system’s transmission load [1]. By increasing the addendum coefficient, enhancing the number of ...
