摘要： A hoist main shaft torque monitoring device based on angle measurement, constituted primarily by a first base, a second base, a light generating unit, a shutter, and a light sensing element; the light source, a first lens, and a first optical aperture arranged in the light generating unit, as well as a second optical aperture, second lens, and light sensing element on the shutter, forming a light source generation, propagation, and reception pathway; when the elevator main shaft is subjected to a certain torque, a corresponding displacement is produced between the first optical aperture and the second optical aperture, thus measuring the change in amount of light ultimately reaching the second optical aperture so as to measure the twist angle of the rotary shaft and finally calculate the magnitude of the shaft torque. Without damaging the original equipment and foundation, the device measures the torque of the shaft at different rotational speeds. The device can measure stationary torque and torque at different rotational speeds of the shaft, without the electromagnetic field interfering with wireless transmission; the device is easy to use, maintenance costs are low, and it is of interest for widespread popularization.

摘要： The displacement detecting apparatus acquires a quantity of a relative rotational displacement between a scale and a detecting head, based on a change of outputs of the light-receiving elements. The displacement detecting apparatus acquires the quantity of the relative rotational displacement between the scale and the detecting head, by combining a quantity of a rough relative rotational displacement between the scale and the detecting head, which has been acquired from an output of the total of light quantities that are output from each of the light-receiving elements in the detecting head, with a quantity of a fine relative rotational displacement between the scale and the detecting head, which has been acquired from an incremental displacement signal that is output from each of the light-receiving elements in the detecting head.

摘要： A torque sensor has a torsion bar coaxially in alignment with input and output shafts, a ring shaped magnet fixed to an axial end of the input shaft, a pair of magnetic yokes fixed to an axial end of the output shaft, and a magnetic sensor for detecting magnetic flux density generated between the pair of magnetic yokes. Each of the magnetic yokes is provided with claws, which are circumferentially spaced at constant intervals, and whose number is equal to that of each of N and S poles alternately arranged circumferentially in the magnet. Each, center of the claws coincides with a boundary between immediately adjacent N and S poles of the magnet, when the torsion bar is not twisted. The magnetic sensor is inserted into an axial gap between the pair of magnetic yokes without contacting the magnetic yokes.

摘要： In a torque sensor, a first detection tube (13) made from magnetic material covers a cylindrical magnetic leak prevention member (12) that is made from nonmagnetic material and covers a first shaft (3) made from magnetic material. Magnetic resistance to magnetic flux, which passes through one end of the first detection tube (13) and one end of a second detection tube (14) that is made from magnetic material and rotates together with a second shaft (4), changes according to elastic relative rotation of the two shafts (3, 4) corresponding to transmitted torque, by providing a plurality of teeth (13a, 14a) along the circumferential direction at the one end of each detection tube (13, 14). The first shaft (3) and the first detection tube (13) are integrated with the magnetic leak prevention member (12) so that they can rotate together, by being inserted in a mold for forming the magnetic leak prevention member (12) before the synthetic resin material is poured into the mold. The circumferential width of each resin holding space (13A) between the teeth (13a) arranged along the circumferential direction at one end of the first detection tube (13) decreases gradually toward the other end of the first detection tube (13). The synthetic resin material solidified in the resin holding spaces (13A) is pressed against the teeth (13a) due to shrinkage thereof.

摘要： A magnetostrictive load sensor includes an upper casing, a lower casing, a coil, and a bobbin. The upper casing having an approximate bell shape has an upper end that is provided with an opening and a lower end that is provided with a notch. The lower casing includes a disk-shaped member and a bar-shaped member that are integral with each other. The coil is formed by winding a conducting wire around the bobbin. A predetermined position of the bobbin is provided with a lead wire outlet for taking out the conducting wire of the coil. A method of manufacturing the magnetostrictive load sensor includes inserting the bar-shaped member into the axial center of the bobbin, and covering the lower casing with the upper casing. In this way, the notch of the upper casing and the lead wire outlet of the bobbin are fitted with each other. An upper end of the bar-shaped member projects through the opening of the upper casing.

摘要： An optical torque sensor comprises a radiation source emitting radiation of at least one wavelength. At least one sensor senses the emitted radiation and generates at least one intensity signal indicative of the intensity of the emitted radiation. At least one signal conditioner is receptive of the emitted radiation and is positioned on a shaft between the radiation source and the at least one sensor thereby conditioning the emitted radiation. A circuit is receptive of the at least one intensity signal and determines the torque acting upon the shaft and compensates for the attenuation of the emitted radiation.
