Computer generating of modified trochoidal profile of gerotor

Abstract

In the paper is presented the theoretical model of the gearing generating with modified trochoidal profile which is applied by the gerotor machines. Gerotors belong to the category of rotated machines with the planetary moving of the working elements. In the paper is shown, how is possibly to describe in parameter form equidistant of the epitrochoidal profile. The profile in contact is the equidistant of the conjugate external envelope. The obtained equations to the calculation with the limiting factors have given the possibility to development of the algorithm and the program for automatic drawing of the trochoidal gearing. Based on the mathematical model is created the computer program in the standard programming language AutoLISP to the calculation of the given curves coordinates and to their automatic generating.
