SOME ISSUES FOR THE RELIEVED CLEARANCE SURFACES OF THE HOB TEETH USED FOR MACHINING INVOLUTE CYLINDRICAL GEARS

Abstract

This paper presents theoretical and practical issues for cutting the relieved clearance surfaces of the hob teeth used for machining involute cylindrical gears. Equations of motion shaping the relieved curve are constructed and described the results by analytical method. The dynamics problems that occur when carrying out the relieved process are calculated based on Nuiton's laws and the law of momentum conservation. The results show that the use of the Archimede curve will ensure technical and economic feasibility for this process. It is possible to use a specialized machine or a CNC machine to carry out the process very simple.
