Abstract
A strain sensor fixing device includes a fixing member including a first side, a second side parallel to the first side, and a surface provided between the first side and the second side and including an opening part, the first side being brought into contact with the first structure, the second side being brought into contact with an end part of the flexure body constituting the strain sensor provided on the first structure, a screw inserted into the opening part and screwed into the first structure, and a rotation stopping part bringing the fixing member into line contact or point contact with the other part to prevent rotation of the fixing member.
Claims18
A strain sensor fixing device comprising:
- a fixing member including a first side, a second side parallel to the first side, and a surface provided between the first side and the second side and including an opening part, the first side being brought into contact with the first structure, the second side being brought into contact with an end part of the flexure body constituting the strain sensor provided on the first structure;
- a screw inserted into the opening part and screwed into the first structure;
- and
- a rotation stopping part bringing the fixing member into line contact or point contact with the other part to prevent rotation of the fixing member.
A torque sensor comprising:
- a first structure;
- a second structure;
- a plurality of third structures connecting the first structure and the second structure;
- a flexure body constituting a strain sensor provided between the first structure and the second structure;
- a first fixing device provided on the first structure to fix a first end part of the flexure body to the first structure;
- and
- a second fixing device provided on the second structure to fix a second end part of the flexure body to the second structure, wherein
- the first fixing device and the second fixing device each includes:
- a fixing member including a first side, a second side parallel to the first side, and a surface provided between the first side and the second side and including an opening part, the first side being brought into contact with the first structure, the second side being brought into contact with an end part of the flexure body constituting the strain sensor provided on the first structure;
- a screw inserted into the opening part and screwed into the first structure;
- and
- a rotation stopping part bringing the fixing member into line contact or point contact with the other part to prevent rotation of the fixing member.
