Design of a gear air engine whit use of „HCR” gearing

Abstract

In the design of a gear air engine is the size of the tooth space fundamental. Most current calculations, however, cannot, especially for non-standard "HCR" gearing, this problem satisfactorily describe.Therefore, it is preferable to use for this type of air engine ,,HCR“ gearing, which maintaining the desired performance, while reduce the overall dimensions of the air engine. This article shows the possibility of calculating the exact size of the tooth space using numerical methods and shows the advantages of a gear air engine whit ,,HCR” gearing, compared to a gear air engine whit standard gearing.
