Method of machining of the flanks of the wheels toothed by machining in involute and device for implementing this process

摘要

The invention relates to a process and a machining device of the sides of the cylindrical gear wheels soaked soaked or not, a straight toothing or helicoidale, internal or external, by machining in involute. A rotation of the base is generated between the tool 9 and a piece 10, as well as a helical movement of the tool 9 or of the piece 10. The relative movement between the tool 9 and the piece 10 is a precision high, rain-effect in this movement being furthermore corrected. In order to minimize the influence of the errors of the tool 9 and its tightening, the number of teeth and z of the tool 9 is fixed in the manner that the transmission ratio izz, in the case or zz, and that the inverse of the ratio lizz, in the case or zz, be a value entire or the ratio of two digits whole as small as possible, z being the number of teeth of the workpiece. The process and apparatus make it possible to carry out by machining in involute cylindrical wheels of a quality of the teeth high.
