DEFINITION OF TOOL PROFILE FOR TOOLING ROTOR OF GEROTOR TRANSMISSION IN CONDITIONS ROUNDING
Keywords:gerotor gear, hobbing cutters, profile tool rack, tangent curve
AbstractThe article is devoted to problems of designing tools for machining for processing the surface cycloidal rotor of gerotor gear. Such tools are in particular hobbing cutters and worm wheels. Despite the fact that the above described tools are known in the world, virtually no information about the method of designing. Mostly it mathematical apparatus that would allow us to build a profile of this tools. Based on the analysis for the rotary tool rake and graphic-analytical synthesis was formulated and solved the problem of the existence of discriminant (tangent curve) of family rotor position, and received its equations, which have advantages over numerical and graphical-analytical methods of construction and are relatively easy for the user. The research results can be used as an engineering methodology in the design and manufacture of hobbing cutters and grinding wheels for machining rotors gerotor gear under the conditions of rounding.
