Abstract
A bidirectional gear set includes a male bidirectional gear component having an array of addendum teeth and a female bidirectional gear component having an array of dedendum sockets, wherein each dedendum socket has a full boundary edge around an open end thereof. One or both of the male and female gear components may have a circular cross sectional geometry, or one may have a non-circular cross sectional geometry. The non-circular cross sectional geometry may be a flat sheet or a sheet with surface contour. In an intermeshed state, neither the male nor the female component can ‘slide’ relative to the other regardless of whether the male and female components are arranged in a parallel or perpendicular orientation. A method of making a bidirectional gear set is disclosed.
