ルクセンサ。[Claims for Utility Model Registration] (1) Fixed members 5 and 6 are attached to the ends of a pair of torsional bars 1 and 2, one of which is on the fixed side and the other is on the torque acting side, and which are coaxial.
are arranged respectively to enable sliding contact, and an annular recess 5a, is provided in the center of the outer peripheral surface of both fixing members 5, 6.
6a, and a supporting member 7 is disposed on the outside of both the fixing members 5, 6 via the sealing member 8, and the recessed parts 5a, 6a of both the fixing members 5, 6 are sealed in the sealing part 1.
3 and 14, and further, holes 9 and 10 are formed in the support member 7 to communicate with the respective sealing parts 13 and 14, and one hole 9 is connected to a fluid supply source, and the other hole is connected to a fluid supply source. A fluid measuring member is connected to 10,
Furthermore, the torque sensor is characterized in that both of the fixing members 5 and 6 are provided with throttle holes 11 and 12 that communicate with the other fixing member. (2) The throttle holes 11 and 12 provided in both the fixing members 5 and 6 and communicating with the other fixing member are arranged so that when torque is applied to the other torsional bar 2 and the angle changes with respect to the one torsional bar 1, are shifted from each other, and the matching effective aperture area 15 of both holes 11 and 12 changes sequentially, and furthermore, the change in the effective aperture area 15 is proportional to the angle change of the torsional bar 2. The torque sensor according to the range 1 above. (3) The aperture holes 11 and 12 provided in both the fixing members 5 and 6 and communicating with the other fixing member are fan-shaped with the axis of the torsional bars 1 and 2 at the center. Torque sensor according to item 2.
