Abstract

Inventia se refera la constructia de masini, in special la prelucrarea rotilor dintate. Procedeul de prelucrare a rotilor dintate precesionale consta in aceea ca semifabricatului i se comunica o miscare de rotatie in jurul axei sale, prelucrarea se realizeaza cu o scula, axa careia, ca si axa rotii prelucrate, trece prin centrul de precesie. Semifabricatului suplimentar i se comunica o miscare sfero-spatiala in jurul centrului de precesie, totodata scula se fixeaza rigid fata de acesta. Dispozitivul contine o carcasa, pe care este montata scula si un mecanism de rotire a rotii prelucrate in jurul axei sale verticale, fixata pe o baza. Dispozitivul suplimentar include o furca in forma de U, fixata pe carcasa, in suporturile furcii este montata articulat o osie a crucii, iar pe a doua osie a ei este montat un sustinator in forma de U, pe care este situata baza pentru fixarea rotii prelucrate. Baza si fiecare dintre osiile crucii sunt legate cu servomotoare. Scula, fixata rigid pe carcasa, si servomotoarele sunt conectate la un sistem de dirijare computerizat. Scula poate fi executata ca un fascicul laser, jet de apa, fascicul de electroni, raze X sau ca un fir de electroeroziune. ŕThe invention relates to the construction of machines, in particular to the processing of gear wheels. The process of processing the precessional gear wheels consists in the fact that the semi-manufacturer is notified of a rotational movement around its axis, the processing is performed with a tool, whose axis, as well as the axis of the processed wheel, passes through the precession center. The additional semi-fabricate is communicated a sphero-spatial movement around the precession center, at the same time the tool is rigidly fixed to it. The device contains a housing, on which is mounted the tool and a mechanism for turning the machined wheel around its vertical axis, fixed on a base. The additional device includes a U-shaped fork, fixed to the housing, a fork axle is mounted in the fork supports, and a U-shaped support is mounted on the second axle, on which the base for fixing the machined wheel is located. . The base and each of the axles of the cross are connected with servomotors. The tool, rigidly fixed to the housing, and the actuators are connected to a computerized steering system. The tool can be executed as a laser beam, water jet, electron beam, X-ray or as an EDM wire. à
