Below, according to Fig. 4 to Fig. 6 second embodiment of the present invention is described.At this, the torque sensor 21 of second embodiment vertically disposes the deformable body 2 of the torque sensor 1 of the first above-mentioned embodiment, and the configuration of the various structure members of corresponding change.
Like Fig. 4 and shown in Figure 5, above-mentioned torque sensor 21 has the deformable body 22 of the cavity bore 22a that is formed with the Luo Baiwaer type, and the mode that this deformable body 22 extends with the intermediate shaft 26 same directions that its edge, length direction side and back literary composition detail disposes.In addition, be formed with stiff end 22b, thereby be fixed on the housing 23 in the upper end of this deformable body 22.
In addition, torque sensor 21 has to follow as the driving of the motor (not shown) of an example of drive source and rotates, and the input shaft 24 that extends of edge and the same direction in the length direction side of deformable body 22.The input gear 25 that can rotate integratedly with it is installed on this input shaft 24.
Dispose the first neutral gear 27a that meshes with above-mentioned input gear 25 in the upper end of above-mentioned deformable body 22, and dispose the second neutral gear 27b in the lower end.These neutral gears 27a, 27b constitute; Can with the upper end and the lower end that connect deformable body 22; And intermediate shaft 26 one that remain on freely on this deformable body 22 through bearing 30,31 rotation are installed on the intermediate shaft 26 rotatably, follow the rotation of above-mentioned input shaft 24 to drive and rotate.
In addition, output gear 29 and above-mentioned second neutral gear 27b engagement.This output gear 29 constitutes, and can be installed in rotatably on the output shaft 28 with output shaft 28 one that remain on freely on the housing 23 through bearing 32,33 rotation, follows the rotation of above-mentioned input shaft 24 to drive and rotates.Through this structure, the rotation of above-mentioned input shaft 24 drives and outputs to output shaft 28 through the first neutral gear 27a and the second neutral gear 27b.At this; These input gears 25, the first neutral gear 27a, the second neutral gear 27b and output gear 29 are spur gears of teeth directional and rotating shaft parallel; Through these gears being changed into the different gear of the number of teeth, the rotation that outputs on the output shaft 28 drives rotation driving speedup or the deceleration that can set freely with respect to input shaft 24.In addition, in torque sensor 21, constitute, the number of teeth of input gear 25 and output gear 29 is identical, can not increase and decrease speed.
Like Fig. 4 and shown in Figure 5, on above-mentioned deformable body 22, be pasted with strain measurement part 34,35,36,37 as an example of strain detecting mechanism, paste two respectively in the side of extending along its length.
The effect of the torque sensor 21 of second embodiment then, is described according to Fig. 6 (a), Fig. 6 (b).At first, shown in Fig. 6 (a), follow the driving of motor, input shaft 24 just changes with torque T1, and input gear 25 is rotation integratedly with it also.Then, accept the rotation of this input gear 25, the first neutral gear 27a and the second neutral gear 27b and intermediate shaft 26 rotate integratedly.In addition, shown in Fig. 6 (b), accept the rotation of this second neutral gear 27b, output gear 29 also rotates with output shaft 28 integratedly.
At this, shown in Fig. 6 (b), when rotational resistance T2 is applied to 28 last times of output shaft, this rotational resistance T2 transmits to the first neutral gear 27a and the second neutral gear 27b from output gear 29.At this moment, with the flank of tooth of the second neutral gear 27b of output gear 29 engagement by these output gear 29 pushings, pushing force F1 acts on the direction with this flank of tooth quadrature.On the other hand, shown in Fig. 6 (a), with the flank of tooth of the first neutral gear 27a of input gear 25 engagement by these input gear 25 pushings, pushing force F2 acts on the direction with this flank of tooth quadrature.Therefore, the F1+F2 that makes a concerted effort of pushing force F1 and pushing force F2 acts on the intermediate shaft 26 that keeps the first neutral gear 27a and the second neutral gear 27b.
In addition, the central point of above-mentioned input gear 25 and the first neutral gear 27a, and the second neutral gear 27b and the central point of output gear 29 be configured on the line of the straight line L parallel with the Width of the length direction side of deformable body 22.Therefore, the meshing point of above-mentioned second neutral gear 27b and output gear 29, and the first neutral gear 27a with the input gear 25 meshing point also be positioned on the line of this straight line L.That is, the application point of pushing force F1 and pushing force F2 is positioned on the line of this straight line L.And these the first neutral gear 27a and the second neutral gear 27b constitute, the acute angle that the active line of pushing force F1 and this straight line are become, and the active line of pushing force F2 equate with the acute angle that this straight line L is become.Therefore, the F1+F2 that makes a concerted effort acts on the direction with the length direction side quadrature of deformable body 22.Therefore, the F1+F2 that makes a concerted effort acts on the deformable body 22 as bending moment, and this deformable body 22 is the fulcrum strain with stiff end 22b.Through utilizing strain measurement part 34,35,36,37 to detect the strain of these deformable bodys 22, thereby can detect torque.
