TORQUE MEASURING MECHANISM USING MAGNET

摘要

The content of the present invention includes an input link which is connected with a driver at one end thereof and is rotated by the driver in one direction; a first displacement sensor which is provided at the other end of the input link and controls the rotation displacement of the input link and the driver; multiple first magnetic substances which are connected by the input link and a connection member and rotate in the same direction as the rotation direction of the input link; multiple second magnetic substances which are provided between the multiple first magnetic substances; an output link which is rotated by the first magnetic substances and the second magnetic substances; and a second displacement sensor which is closely attached to one surface of the output link and measures the rotation displacement of the output link. The connection member provides includes a cylindrical body having a penetration hole for the input link; and multiple connection units connected with the multiple first magnetic substances. Therefore, an external force supplied from the outside can be measured without using the conventional equipment with a complex structure and a larger volume such as a load cell and a strength gauge. By the simple structure, the torque measuring apparatus can be compact and lightweight to be conveniently used by directly applying to rotational shafts of various medical apparatuses, industrial machines, and tools.
