Title:
TORQUE SENSOR, TORQUE SENSOR UNIT, AND PENETROMETER
Document Type and Number:
Japanese Patent JP2017129364
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a torque sensor that is arranged between coaxially arranged two members and can detect a rotational load that occurs between the two members.SOLUTION: A torque sensor 10 comprises: a plurality of rod-like elastic bodies 25 arranged in parallel; a first holder 26 for holding the upper end portion (first end portion) 25a of each elastic body 25; a second holder 27 for holding the lower end portion (second end portion) 25b of each elastic body 25 and arranged coaxially with the first holder 26; and a detector 28 for detecting the relative rotation angles of the first holder 26 and second holder 27 as the first holder 26 and the second holder 27 rotate around their axis line L relative to each other. The first holder 26 is coaxially connected to a rod 5 in a state of being incapable of relative rotation, and the second holder 27 is coaxially connected to a screw point 6 in a state of being incapable of relative rotation, the torque sensor 10 detecting a rotational load (torque) that occurs between the rod 5 and the screw point 6.SELECTED DRAWING: Figure 4
