摘要： A torque sensor (200) includes a sensor unit (222), a resilient body (213), and a detection unit (223). The sensor unit (222) detects, from an output unit that is a rotational body of an actuator, a rotational position in an annular first area positioned at a first distance from a rotation center, and a rotational position in an annular second area positioned at a second distance longer than the first distance from the rotation center. The resilient body (213) is provided between the first area and the second area. The detection unit (223) detects a torque applied to the output unit, on the basis of a result of the detection by the sensor unit (222).

摘要： A torque meter shaft that includes a hollow tube, a ring with ring tabs, the ring enveloping the hollow tube, a shaft with shaft tabs and a deformable section, the shaft disposed within the hollow tube such that the ring tabs and the shaft tabs correspond forming an inter-locking non-contact fit, and a first spline coupling and a second spline coupling. The first spline coupling communicates with an engine such that torque from the engine is transferred to the deformable section and elastically deforms when torque is applied to the first spline coupling and the shaft tabs change radial position relative to the position of the ring tabs such that relative change in torque can be measured, and when torque results in creating a shaft deformation that passes the material yield point, the ring tabs and shaft tabs contact each other, and the ring tabs are pushed back into a new position that compensates for the shaft deformation allowing the engine to maintain its full power capacity.

摘要： A method and a device for measuring the torque in the drivetrain (1) of a wind power plant is described, having at least two incremental encoders (7, 8) which are positioned at two different positions on at least one shaft (3) of the drivetrain (1) and which each supply periodic rotational signals, wherein the phases of the rotational signals are evaluated in order to detect a phase shift, and a torque of the shaft (1) is determined from the phase shift. The detected phase shift is corrected as a function of a zero load phase shift (AZero), using a rigidity factor K, wherein, in order to determine the zero load phase shift (AZero) and the rigidity factor K, in-situ calibration is carried out before and/or between the torque-determining processes. The in-situ calibration is performed at zero load of the wind power plant, i.e. below a rated rotational speed and with a generator torque equal to zero, and at the rated load of the wind power plant, i.e. at the rated rotational speed and with a generator torque greater than zero.

摘要： In some examples, a downhole torque measurement tool comprises a first surface of a structure and a second surface of the structure. The second surface is facing the first surface, and a shear stress sensor is positioned on the first surface. A flexible coupling is positioned between the shear stress sensor and the second surface, and the flexible coupling is coupled to the first and second surfaces.

摘要： The purpose of the present invention is to provide a control device for a dynamometer system, with which, by a simple method, an unloaded state can be reproduced highly accurately when a test piece is started. A dynamo control device 6 is provided with: an integral control input computation unit 611 for computing the integral value of axle torque deviation, and multiplying the sum thereof and a correction value by an integral gain to compute an integral control input; a correction value computation unit 612 for multiplying an inertia compensation quantity Jcmp by the dynamo rotation frequency to compute a correction value; a non-integral control input computation unit 613 for designating, as a non-integral control input, the output of a prescribed transmission function Ge0(s) having axle torque deviation as input; and a totaling unit 614 for totaling the integral control input and the non-integral control input in order to generate a torque current command signal to the dynamometer. The transmission function Ge0(s) of the non-integral control input computation unit 613 is derived by separating the integrator from a transmission function Ge(s) having an axle torque control function, in such a way as to satisfy the relational equation (Ge(s)=Ki/s+Ge0(s)).

摘要： Disclosed is a rotor for a torque sensor configured to improve a mechanical coupling force with respect to a jig in a process of adjusting a torque center, thus enabling a fine adjustment, the rotor including a rotor body having a sleeve coupled to a rotating shaft and a yoke protruding from an outer circumference of the sleeve, a ring-shaped magnet coupled to an outer circumference of the yoke, and an anti-slip structure formed on the rotor body and partially coming into contact with a jig during a rotating process for adjusting a torque center, thus inhibiting slipping between the rotor body and the jig when a rotating force is transmitted, so that slipping between the jig and the rotor body is inhibited to enable precise transmission of the rotating force whereby accuracy is improved during fine adjustment of the torque center.

摘要： Example embodiments may relate to a compliant force sensor used in actuated and non-actuated systems. For instance, a structure (e.g., a transmission) may be configured to receive a force based on application of a load to the structure. A rigid member may be coupled to the structure and configured to provide a first deformation based on application of the load to the structure and transfer of the force to the rigid member. An elastic element may provide compliance and may be connected to the rigid member such that the rigid member is configured to further transfer the force to the elastic element. The elastic member may be configured to provide a second deformation under application of the load that is larger than the first deformation. A sensor may be positioned on the rigid member and configured to measure the first deformation independent of hysteresis and non-linearity in the elastic element.
