“…Based on the 20-years experience of the authors and over 60 publications on the problems of the asymmetrical profile, it has been found that a major problem in its use is the reversal of the direction of movement [1,2,3]. As a solution, the authors set out [4,5] a basic principle of interlocking, allowing the making of gears with an unachievable until now quality and strength indicators [12].…”

The article presents specific practical solutions for optimal geometric design of evolvental cylindrical gears with an asymmetric profile of cogs in the context of the basic principle of cog interlocking. In order to achieve unknown until now quality indicators, constructions with a minimum number of cogs and a maximum angle of interlocking are shown, which allow for the production of off-polar gears and significantly increase the gear ratio of the differential and planetary mechanisms. In the process of determining the geometrical parameters of the cogwheels of the gear, the “classical approach” is used by analogy with the parameters of the instrument, necessary for the production of the small-module cogwheels of the gear.
