Abstract:
Gears with a cycloid profile have very good working characteristics in kinematic and dynamic domains. These types of gears generally have convex on concave contact surfaces, which influences the decrease in stress as well as contact wear of the sides of the gearing. The most commonly used profile of cycloid discs is an equidistant of the shortened epitrochoid. Given that this is a complex curve, this paper gives a program code for its automated generating. Using the input parameters of the cycloid disc, as well as those of other elements of the cyclo drive which are in contact with the cycloid disc (central static gear rollers and output rollers), the program creates a drawing of the cycloid disc as well as the aforementioned rollers. The particular contribution of this paper is that the acquired drawing is made for any set rotation angle of the input shaft. The drawing represents a very valuable and time efficient initiate for a planar analysis of stress and deformation states using finite element analysis for cyclo drives.
