Design of Geometrical Parameters and Kinematical Characteristics of a Non-circular Gear Transmission for Given Parameters

In this paper, the authors present design of a suitable gear transmission with continuously changing ratio in range from 0.5 through 1.0 to 2.0 and back during one revolution intermeshing gears, according demands specified for practical application. The train was designed as pair identical elliptical gears procedure pitch curve (ellipse) is described. center rotation each coincident ellipse foci, so are placed eccentrically. teeth have involute profiles, but involutes active passive tooth sides different. These an asymmetrical profile. final part, paper deals kinematical characteristics non-circular transmission, which differ standard circular transmissions constant ratio.
