  • Publication number: 20190212216
    Abstract: A torque detector detects a torsional torque between a first shaft and a second shaft based on a torsional displacement of an elastic member coaxially connecting the first shaft and the second shaft. The torque detector includes a magnetic flux generation unit and a magnetic sensor. The magnetic flux generation unit rotates with rotation of the first shaft and includes a first pole and a second pole into and out of which lines of magnetic force enter and exit. The magnetic sensor rotates with rotation of the second shaft and includes a detection surface for detecting a magnetic flux or a magnetic flux density. The first pole and the second pole are arranged to face each other across the magnetic sensor.

  • Patent number: 10274385
    Abstract: A torque detecting apparatus includes a first shaft; a second shaft; an elastic member coaxially linking the first and second shafts; and a magnet attached to the first shaft; a pair of magnetic yokes composed of a first magnetic yoke and a second magnetic yoke, the first and second magnetic yokes being fixedly installed on the second shaft; and a magnetic sensor. Each magnetic yoke includes an opposing portion and a wall portion. The opposing portion is opposed to the magnet and displaced circumferentially relatively to the magnet when the elastic member is subjected to a torsional displacement. The wall portions of the first and second magnetic yokes are separated and positioned outside the opposing portions in the radial direction. The wall portions of the first and second magnetic yokes extend to be mutually opposed. The magnetic sensor is positioned between the wall portions.

  • Patent number: 10139747
    Abstract: An electrophotographic roller includes an electro-conductive shaft core including a metallic layer at its surface, and an elastic layer on the shaft core. When kinetic friction coefficients of an outer peripheral surface of each end portion of the shaft core with respect to polyester resin are measured for one rotation of the shaft core, an average value ?r of the kinetic friction coefficients is 0.05 to 0.50. When each outer peripheral surface is divided into three equal ranges, defined as a region A1, a region A2, and a region A3, in a peripheral direction of the shaft core, each of the regions has a location where the kinetic friction coefficients fall within a range of 1.5 ?r to 1.8 ?r, and a location where the kinetic friction coefficients fall within a range of 0.2 ?r to 0.5 ?r.

  • Patent number: 10132702
    Abstract: Claw portions opposing a magnet are disposed on inner edges of a first yoke and a second yoke. Wall portions are disposed on outer edges of the first yoke and the second yoke so as to extend in an axial direction. A distal end of the wall portion and another distal end of the other wall portion are spaced apart from each other in the axial direction and disposed to oppose each other. A magnetic sensor is disposed between the distal ends in the axial direction. End faces oblique to the axial direction are disposed on the distal ends and a distance between the distal ends on a radially inner side is made shorter than a distance between the distal ends on a radially outer side.
