Sažetak
This article presents a study of the amount of harmonic gear system backlash. The study shows a method for an effective measuring of the amount of backlash in harmonic gear systems. Given that this calculation tasks demand a lot of iterative operations, this article introduces a new method for creating 2D and 3D models of a harmonic gear system. At the same time, this study presents a new way of generating the geometry of a wave generator with a parametrically modified geometry. Introduction of the parametric model of a wave generator allows a rapid optimization of construction parameters, thus securing correct dimensioning and evaluation of the amount of backlash. When creating the computational model, operational characteristics were taken into consideration, therefore, the 2D and 3D computational models were created to correspond with real operation conditions to the greatest extent possible. The results of the analysis imply that the suggested method of examining the design parameters of the wave generator due to the harmonic gear system backlash is effective and correct. The benefit of this article is mainly to introduce a new dynamic computational model of a harmonic gear system and to optimize the construction parameters of the wave generator in line with the amount of backlash, which is manifested in the higher accuracy of the harmonic gear system. In the conclusion of this article we state our recommendations and acquired knowledge.
