Abstract
(EN)
Provided is a technology that contributes to further improvement of a transmission mechanism for transmitting motive power in a work tool which performs processing work on a workpiece by driving a tipped tool. According to the present invention, a vibration tool 1 is provided with a motor 20, a spindle 30, and a transmission mechanism 4. The transmission mechanism 4 is configured to transmit motive power generated by driving of the motor 20 to the spindle 30, and to turn back and forth the spindle 30 within a prescribed angular range around an axis line A1. The transmission mechanism 4 incudes: links 41-44 each having a link hole therein; and columnar pins 46-49. The link holes are each formed so as to have a circular shape in a cross-section orthogonal to the axis line, and are each encircled by an inner wall surface that is configured to constitute a transmissive surface capable of performing transmission of motive power with respect to the pins 46-49. The pins 46-49 being inserted in the link holes are configured to perform transmission of motive power with respect to the links 41-44 in a direction orthogonal to the axis line of the corresponding link holes.

L'invention concerne une technologie qui contribue à une amélioration supplémentaire d'un mécanisme de transmission pour transmettre une puissance motrice dans un outil de travail qui effectue un travail de traitement sur une pièce à travailler par l'entraînement d'un outil à pointe. Selon la présente invention, un outil de vibration (1) comporte un moteur (20), un arbre rotatif (30), et un mécanisme de transmission (4). Le mécanisme de transmission (4) est conçu de façon à transmettre la puissance motrice générée par l'entraînement du moteur (20) à l'arbre rotatif (30), et à faire tourner dans un sens et dans l'autre l'arbre rotatif (30) à l'intérieur d'une plage angulaire prescrite autour d'une ligne axiale (A1). Le mécanisme de transmission (4) comprend : des liaisons (41 - 44) ayant chacune un trou de liaison à l'intérieur de cette dernière ; et des broches en colonne (46 - 49). Les trous de liaison sont chacun formés de façon à avoir une forme circulaire dans une section transversale orthogonale à la ligne axiale, et sont chacun encerclés par une surface de paroi interne qui est conçue de façon à constituer une surface de transmission pouvant effectuer une transmission de puissance motrice vis-à-vis des broches (46 - 49). Les broches (46 - 49) insérées dans les trous de liaison sont conçues de façon à effectuer une transmission de puissance motrice vis-à-vis des liaisons (41 - 44) dans une direction orthogonale à la ligne axiale des trous de liaison correspondants.
