Patent

CA 2615131

Torque limiting devices, tools comprising torque limiting devices, and methods for using torque limiting devices are disclosed. A torque limiting device can include a first and a second surface disposed in engageable relationship. Within a predetermined torque range, the first and second surfaces can rotate together such that a torque applied to the first surface is translated to the second surface. When the torque applied exceeds a predetermined torque limit, the first and second surfaces can disengage from each other, preventing translation of the excessive torque between the surfaces and any attached implements. By freely rotating one disengaged surface relative to the other surface, the surfaces can be re-engaged to operate the device.

L'invention porte sur des limiteurs de couple, des outils les comprenant, et les procédés d'utilisation desdits limiteurs. Un tel limiteur de couple comporte une première et une deuxième surface en contact, et tournant ensemble pour un couple appliqué prédéterminé, de manière à ce que ledit couple soit transféré de la première surface à la deuxième. Lorsque le couple appliqué dépasse un seuil prédéterminé, la première et la deuxième surface se désolidarisent l'une de l'autre en empêchant le transfert de tout couple excessif entre elles et les accessoires attenants. En faisant tourner librement une surface désolidarisée par rapport à l'autre, on les resolidarise pour faire fonctionner le dispositif.
