PARAMETRIC DRAWING OF A CYCLO DRIVE SHORTENED EQUIDISTANT EPITROCHOID GEAR

Abstract

Cycloid profile gears have very good working characteristics in both kinematic and dynamic domains. The most frequently used profile of cycloid gears is an equidistant of the shortened epitrochoid. These types of gears commonly have convex on concave contact surfaces, which influences the decrease in stress as well as contact wear. Given that this is a complex curve, this paper gives a program code made in AutoLISP for its automated generating in AutoCAD. Using the input parameters of the cycloid disc the program creates a two dimensional drawing of the cycloid disc profile. The drawing represents a very valuable and time efficient initiate for cycloid drive design.
