Abstract
Narzedzie spiralno - srubowe do walcowania skosnego kul skladajace sie ze stopniowego walca, w sklad którego wchodzi czop napedowy, czopy lozyskowe oraz stozkowy walec roboczy, charakteryzuje sie tym, ze na stozkowym walcu roboczym od strony przeciwnej do czopa (1) napedowego znajduje sie redukcyjna powierzchnia (3) wejsciowa o dlugosci (L1), która posiada stozkowy ksztalt o stalym kacie rozwarcia (?), nastepnie za redukcyjna powierzchnia (3) wejsciowa znajduje sie stozkowa powierzchnia (4) robocza o dlugosci (L2) i stalym kacie rozwarcia (2?), na której od strony redukcyjnej powierzchni (3) wejsciowej znajduje sie klinowy wystep (5) srubowy, o stalym kacie rozwarcia (?) i pochylenia powierzchni bocznych (?), stopniowo zwiekszajacych swoja wysokosc i szerokosc, zas za klinowym wystepem (5) srubowym znajduja sie ksztaltowe wystepy (6a), (6b) i (6c) srubowe, o wkleslych powierzchniach (7), (8), (9) bocznych, które tworza wykrój w ksztalcie walcowanych kul o promieniu (R) równym ksztaltowanej kuli, przy czym ksztaltowe wystepy (6a), (6b) i (6c) srubowe stopniowo zwiekszaja swoja szerokosc i wysokosc, zas za ksztaltowymi wystepami (6a), (6b) i (6c) srubowymi znajduje sie walcowa powierzchnia (10) wyjsciowa o stalej dlugosci (L3). Na koncowym ksztaltowym wystepie (6c) srubowym, znajduje sie dodatkowy wystep (12) rozdzielajacy uksztaltowane kule od pólfabrykatu. Na powierzchniach bocznych klinowego wystepu (5) srubowego, znajduja sie naciecia.Spiral-screw tool for skew rolling of balls consisting of a step roller, which includes a drive pin, bearing pins and a tapered work roller, characterized by the fact that the tapered work roller has a reducing surface on the side opposite to the drive pin (1) (3) entrance with a length (L1), which has a conical shape with a fixed angle of opening (?), Then behind the reduction surface (3) the entrance has a conical surface (4) with a length (L2) and fixed angle of opening (2? ), on which from the reducing side of the (3) entry surface there is a wedge-shaped protrusion (5), with a fixed opening angle (?) and inclination of the side surfaces (?), gradually increasing its height and width, and behind the wedge-like protrusion (5) Screw projections (6a), (6b) and (6c) screw projections (7), (8), (9) lateral, which form a pattern in the shape of rolled balls with a radius (R) equal to a ball-shaped ball, where the protruding protrusions (6a), (6b) and (6c) screw gradually increase their width and height, while behind the protruding protrusions (6a), (6b) and (6c) there is a cylindrical surface (10) fixed length (L3). On the final shaped projection (6c) screw, there is an additional projection (12) separating the shaped balls from the blank. There are cuts on the lateral surfaces of the wedge projection (5).
