On this new tooth profile, the continuous con- ductivity has called for increasingly higher requirements of gear cave/convex contact is carried out from its dedendum to its ad- transmission performance. The key factor influencing dynamic dendum, where the engagements with a relative curvature of zero gear performance is the form of the meshed gear tooth profile. To are assured at many points. Here, this kind of point is called the improve a gear’s transmission performance, a new type of gear null-point (N-P). The presence of many N-Ps during the mesh called the LogiX gear was developed in the early 1990s. How- process of LogiX gears can result in a smaller sliding coeffi- ever, for this special kind of gear there remain many unknown cient, and the mesh transmission performance becomes almost theoretical and practical problems to be solved. In this paper, the rolling friction accordingly. Thus this new type of gear has many design principle of this new type of gear is further studied and advantages such as higher contact intensity, longer life and a the mathematical module of its tooth profile deduced. The in- larger transmission-ratio power transfer than the standard in- fluence on the form of this type of tooth profile and its mesh volute gear. Experimental results showed that, given a certain performance by its
