Title (EN) POWER TOOL
(FR) OUTIL ÉLECTRIQUE
(JA) 電動工具
Abstract:
(EN) A torque transmission mechanism (5) transmits the torque generated by rotation of a drive shaft (4) to an output shaft (6). A clutch mechanism (8) is provided between a motor (2) and the torque transmission mechanism (5). The torque transmission mechanism (5) comprises a magnet coupling (20) that has a driving magnet member connected to the drive shaft (4) side and a driven magnet member connected to the output shaft side (6). The driving magnet member and the driven magnet member are disposed with magnet faces thereof opposed, each magnet face having an alternating arrangement of S pole and N pole. The clutch mechanism (8) transmits the torque generated by rotation of the drive shaft (4) to the driving magnet member but does not transmit to the drive shaft (4) the torque that the driving magnet member receives from the driven magnet member.
(FR) L'invention concerne un mécanisme de transmission de couple (5) qui transmet le couple généré par la rotation d'un arbre d'entraînement (4) à un arbre de sortie (6). Un mécanisme d'embrayage (8) est mis en œuvre entre un moteur (2) et le mécanisme de transmission de couple (5). Le mécanisme de transmission de couple (5) comprend un couplage d'aimant (20) qui a un élément d'aimant d'entraînement qui est relié au côté de l'arbre d'entraînement (4), et un élément d'aimant entraîné (22) relié au côté de l'arbre de sortie (6). L'élément d'aimant d'entraînement et l'élément d'aimant entraîné sont disposés avec leurs faces d'aimant opposées, chaque face d'aimant ayant un agencement alterné de pôle S et de pôle N. Le mécanisme d'embrayage (8) transmet le couple généré par la rotation de l'arbre d'entraînement (4) à l'élément d'aimant d'entraînement mais ne transmet pas à l'arbre d'entraînement (4) le couple que l'élément d'aimant d'entraînement reçoit en provenance de l'élément d'aimant entraîné.
(JA) トルク伝達機構(5)は、駆動軸(4)の回転により生じるトルクを出力軸(6)に伝達する。クラッチ機構(8)は、モータ(2)とトルク伝達機構(5)の間に設けられる。トルク伝達機構(5)は、駆動軸(4)側に連結される駆動マグネット部材と、出力軸(6)側に連結される従動マグネット部材とを有するマグネットカップリング(20)を備える。駆動マグネット部材および従動マグネット部材は、それぞれS極およびN極を交互に配置した磁石面を対向させて配置される。クラッチ機構(8)は、駆動軸(4)の回転により生じるトルクを駆動マグネット部材に伝達する一方で、駆動マグネット部材が従動マグネット部材から受けるトルクを駆動軸(4)に伝達しない。
