摘要： An optical torque sensor (1) for measuring a torque on a rotating system having a shaft is presented. The optical torque sensor comprises two wedge prisms (3, 4) coupleable to an input portion and an output portion of the shaft. Furthermore, a light source (5) is arranged to emit a light beam through the wedge prisms toward an optical position sensor (6) which is arranged to receive the light beam and configured to provide a position signal indicative of a position of an incident light spot in the optical position sensor. The optical torque sensor further has control circuitry (30) configured to receive the position signal and to determine a torque value applied to the input portion based on this position signal. Hereby, a cost effective, robust, and compact optical torque sensor is presented, the sensor is particularly suitable for automotive applications such as power steering mechanisms. Also, a power steering system employing such an optical torque sensor is disclosed.

摘要： The invention relates to a gearbox having a sensing device (109) for sensing a torque which acts on a drive shaft (101), an output shaft (102) or a shaft which can be driven by the drive shaft (101). The sensing device (109) is electrically connected to an integrated energy-generating device. A rotor (192), which is arranged inside the gearbox housing (103) and connected in a rotationally fixed fashion to a shaft which can be driven by the drive shaft (101), is assigned to the energy-generating device. A bearing (194), which is secured by a housing lid (193), is assigned to this shaft. The housing lid (193) surrounds the rotor (192) in this context. The energy-generating device is assigned a stator (191) which is mounted on the housing lid (193) within the gearbox housing (103).

摘要： Methods and apparatus are provided for determining torque in an environmentally isolated system. A drive system is coupled to the environmentally isolated system via a non-contact, magnetic coupling that has a known angular stiffness and at least two coupling sections. A relative deflection of each coupling section is optically measured, and the torque is determined based on the relative deflection and the known angular stiffness.

摘要： An apparatus comprises a rotatable shaft (20) and first and second targets (32, 34) coupled to the rotatable shaft (20) so as to rotate therewith, a first probe (12) for transmitting a first transmission signal to the first target (32) and receiving a first response signal from the first target (32), and a second probe (14) for transmitting a second transmission signal to the second target (34) and receiving a second response signal from the second target (34). The apparatus further comprises a processor (10) operatively coupled to the first and second probes (12, 14) for determining a torsional displacement of the shaft based on the first and second response signals received by the first and second probes (12, 14), respectively. The processor (10) then determines a torque imposed on the rotatable shaft (20) based on its torsional displacement.
