Design and analysis of cam gears using a computer

To reduce energy consumption in mechanisms and machines, it is necessary to develop mathematical models that can be used at the initial design stage. One of the most important design problems is that numerous quality criteria depending on speed and load must be taken into account. It is especially difficult to deal with the criterion of mechanism efficiency. In this paper, the dependence of the cam gear efficiency on the pressure angle is investigated. This criterion was studied using a computer on the basis of the developed mathematical model, which provided new previously unknown results. When performing graphic calculations, the pressure angle was recommended to reduce in order to reduce the frictional forces. Mathematical modeling showed that the instantaneous efficiency of the cam gear increases with the pressure angle. This study makes it possible to improve the calculation of the cam gear in course design in the theory of mechanisms and machines.
