    摘要： A thread rolling method for a gear using cylindrical capable of achieving a proper tooth profile by the use of cylindrical dies in which no slippage occur during the processing is provided. The method includes the steps of placing a work having a cylindrical outer surface to be supported to a support to be freely rotatable about a rotation axis of the cylindrical outer surface, placing a pair of the cylindrical dies each rotatable about an axis parallel to the rotation axis to face each other across the work, thrusting the pair of cylindrical dies against the work, the cylindrical dies being synchronized with each other in rotating speed and thrusting amount via a drive mechanism, and determining an outer diameter of the work, when rotary movement of the cylindrical dies and the work rotated together is shifted from friction gear movement based on thrusting forces exerted from both the cylindrical dies and the work to gear movement based on the engagement between the work and the cylindrical dies at tooth grooves formed in the work by thrusting the cylindrical dies against the work, in which a dimension obtained by dividing an outer circumferential dimension of a dedendum circle of the tooth grooves by the number of teeth to be formed is equal to an addendum circular pitch of each of the cylindrical dies.

    摘要： The present invention relates to a system for and a method of manufacturing a linear gear (rack gear), in which a forming roll and a guide roll are used to form gear teeth in a sequential manner so as not to require a high load, thereby enabling to easily manufacture the rack gear. A system for manufacturing a rack gear according to the invention includes a forming roll having a convexo-concave portion formed on a part of the surface contacting with a linear bar, a guide roll adapted to roll while facing the forming roll, and at least one support member for supporting the linear bar so as to allow the linear bar to linearly move. A method of manufacturing a rack gear according to the invention includes a first step of passing a linear bar through between a pair of rollers provided in front of a forming roll and a guide roll, a second step of charging the linear bar into a charging hole between the forming roll and the guide roll, a third step of rolling the forming roll and the guide roll to partly form teeth on the outer circumferential surface of the linear bar, and a fourth step of rolling the forming roll and the guide roll forward or backward to discharge the linear bar.

    摘要： A form rolling tool for spline machining enabling an increase in durability by securing the strength of machining teeth and manufacturable at low cost and a method of manufacturing the form rolling tool. In the method, a bristle brush is translated in the direction of an arrow L while rotating to apply chamfering to the machining teeth (12) by abrasive grains adhered to the bristles of the bristle brush so as to form chambered face parts (40) at the peripheral edge parts of the scrape-off face parts (30) of the form rolling tool. Since the large number of machining teeth (12) can be continuously chamfered at a time and a working time can be remarkably reduced, the form rolling tool for spline machining can be manufactured at low cost. Also, the chamfered face parts (40) are formed at the peripheral edge parts of the scrape-off face parts (30), the durability of the form rolling tool can be increased by suppressing a damage to the machining teeth (12) by chipping.

    摘要： In forming an internal gear from a blank (2) for the internal gear, first the blank (2) is fitted on a form (3) and fixed thereon by a press form (4). Then, a forming roll (5) is moved in the direction of arrow (B) in Fig. 6 while rotating the form (3). This presses the inner peripheral surface of the blank (1) against an external gear section (3b) formed on the outer peripheral surface of the form (3) to form an internal gear section (1c) in the inner peripheral surface of the blank (2). The direction of rotation of the form (3) is selected such that the end of an external gear section (3b) positioned forwardly of the direction of feed of the forming roll (5) precedes the end positioned rearwardly of the direction of feed as seen in the direction of rotation of the form (3). (That is, the direction of arrow (A) in Fig. 6 is selected.)

    摘要： Eine Vorrichtung (1) zum Präzisionsrollen der Mantelfläche (2) eines rotationssymmetrischen Bauteils (3) weist mindestens zwei beabstandete Rollwerkzeuge (4, 5) auf. Es ist ferner eine Messeinrichtung (9) zum Messen des Ist-Rohteildurchmessers des Bauteils (3) und eine Auswerteeinrichtung (10) zum Vergleichen des gemessenen Ist-Rohteildurchmessers des Bauteils (3) mit einem vorgegebenen Rohteildurchmesser und zum Bestimmen eines Korrekturwerts aus dem Ergebnis des Vergleichs des Ist-Rohteildurchmessers des Bauteils (3) mit dem vorgegebenen Rohteildurchmesser vorgesehen. Eine Steuerung (11) dient zum Einstellen des Abstands zwischen den mindestens zwei Rollwerkzeugen (4, 5) in Abhängigkeit von dem Korrekturwert. Bei dem zugehörigen Verfahren wird zunächst der Ist-Rohteildurchmessers des Bauteils (3) gemessen. Dann wird der Ist-Rohteildurchmesser des Bauteils (3) mit einem vorgegebenen Rohteildurchmesser verglichen und ein Korrekturwerts aus dem Ergebnis des Vergleichs des Ist-Rohteildurchmessers des Bauteils (3) mit dem vorgegebenen Rohteildurchmesser bestimmt. Daraufhin wird der Abstand zwischen den mindestens zwei Rollwerkzeugen (4, 5) in Abhängigkeit von dem Korrekturwert eingestellt.
