81 | Werkzeug und Verwendung desselben zur Herstellung von Gewinden | EP05024541.4 | 2004-04-19 | EP1629919A3 | 2006-07-26 | Mann, Jürgen |
Beschrieben wird ein Werkzeug zur Herstellung von Gewinden, insbesondere von Innengewinden, das ein Herstellungsverfahren ermöglicht, bei dem die Innenoberfläche (16) einer Werkstückbohrung mittels spanloser Druckumformung bearbeitet wird. Das Werkzeug hat einen Formkopf (18; 118) mit zumindest zwei nach der Art eines Gewindefräsers ausgebildeten und in konstantem axialen Abstand (T) zueinander stehenden Profilvorsprüngen (20), die über den Umfang durchgehend und mit sich über den Umfang verändernder radialer Erstreckung (ERMIN, ERMAX) ausgebildet sind, so dass im Bereich eines jeden Profilvorsprungs (20) über den Umfang zumindest ein Drückstollen (22; 122) entsteht. Die Profilvorsprünge (20) bilden mit der sich über den Umfang ändernden radialen Erstreckung (ERMIN, ERMAX) über den Umfang jeweils mehrere Drückstollen (22; 122) aus. Die Drückstollen (122) benachbarter Profilvorsprünge sind in Umfangsrichtung zueinander versetzt. Um Gewinde unterschiedlicher Nenndurchmesser besonders wirtschaftlich und mit verbesserter Gefügequalität im Bereich des Gewindes herstellen zu können, wird das Gewinde dadurch gebildet, dass das Werkzeug zunächst an einer Umfangsstelle der Werkstückbohrung in das Werkstück eingefahren wird, vorzugsweise auf volle Gewindetiefe gebracht wird, und unter Beibehaltung der zur Achse der Werkstückbohrung eingestellten Exzentrizität der Drehachse eine 360° durchlaufende Relativ-Kreisbewegung (Zirkularbewegungs) bezüglich der Achse der Werkstückbohrung ausführt, während der Formkopf gleichzeitig eine konstante axiale Relativ-Vorschubbewegung um das Maß der herzustellenden Gewindsteigung ausführt. |

A method of machining a screw is provided that is capable of preventing formation of a protruding section at a thread tip section. A thread is formed by cutting on a cylindrical body, and a surface of the thread is plastically deformed by rolling. Because of the cutting, a width between-side surfaces of a thread tip section is in a narrowed state as compared to a normal width. This width is narrowed toward a tip of the thread while a thread body section has a width expanded as compared to a normal width. Consequently, the side surfaces are formed to bulge by an excess thickness portion as compared to normal side surfaces. The rolling plastically deforms both side surfaces to cause the excess thickness portion to plastically flow toward the side surfaces. | ||||||

There is provided an R-θ table apparatus which freely movies one table on a plane in the forward-and-rearward and leftward-and-rightward directions and in the rotational direction. The R-θ table apparatus changes a horizontal distance between a center line of a main axis of a driving apparatus and the action point by elevating an elevating base, and a table is moved to an arbitrary position without rotating along a guide member. | ||||||
93 | Screw or nut with a thread a pitch of which varies and tool to produce said screw or nut | US13146195 | 2010-01-19 | US09352382B2 | 2016-05-31 | Joachim Galipaud |
The distribution of load stresses on threads engaged with a standard screw or nut is very unequal. Indeed, the first threads in engagement support a large majority of the load. So if the load is too important, the threads give way and the function is not provided any more by the screw or the nut. In the prior art, threads are known whose depth or pitch varies a lot in order to cause a self-clamping. In particular, the invention aims at optimizing the resistance and the fatigue resistance of the screws by distributing the load at the very best on their threads without causing this self-clamping. It was shown that the control of the pitch variation, within a chosen pitch tolerance, makes it possible to control the stress distribution on the threads. It is possible to determine a different variation for each load case encountered. | ||||||

Method for the production of a spindle nut (3) of a spherical thread drive mechanism, whereby the spindle nut (3) has at least one screw-shaped track (4) formed as a single piece on its inner circumference, whose threads (38) are limited by shoulders (6). The shoulder (6) is interrupted by a deflecting recess (23) at at least one deflecting position, in order to deflect balls (13) out of one thread into an adjacent thread (38). The method includes locating a tool arbor (56) in a hollow blank (57), whereby the tool arbor (56) has on its outer circumference a counter profile of the screw-shaped track (4) and a projecting part (59) for each deflecting recess. A tool operates on and reshapes the blank (57) from the exterior by exercising radial forces (F), whereby during the reshaping process the inner circumferential surface of the blank (57) is shaped according to the counter profile and to the projecting part (59) of the tool arbor (56) such that the screw-shaped track (4) and the deflecting recess (23) are formed. |
