Title: Torque detector
Inventor: KAJIWARA YASUNARI
IPC: G01L3/06
Filed: 1981-12-22
Abstract: PURPOSE:To detect torque with a mechanical means of simple structure, by a method wherein the difference in rotational phase between input and output shafts due to the torque applied thereto is detected as a rotational angle of a central rotary shaft of a detecting plate through rotary shafts of two gears. CONSTITUTION:When a torque is applied, a torsion is generated between an input shaft 2 and an output shaft 3. Since the shafts 2, 3 are meshed with helical splines, opposite in direction to each other, of a movable gear 8, the movable gear 8 is subjected to a force causing the same to move axially. The amount of movement of the movable gear 8 is determined when the force balances with the deflection amount of an initially coned disc spring 9 or 10. The torsion between the input shaft 2 and the output shaft 3 causes a difference in phase between the shafts 2 and 3, and small bevel gears 16, 17 are subjected to not only a rotational force but also a force urging the gears 16, 17 to rotate around a central rotary shaft 19a of a detecting plate 19. The rotational angle is proportional to the torsion between the input shaft 2 and the output shaft 3. By measuring the rotational angle of the central rotary shaft 19a of the detecting plate 19, the torque can be measured.

IPC: B21D7/16
Filed: 1983-11-08
Abstract: PURPOSE:To reduce thinning that occurs in back side and tensile residual stress that occurs on outer surface and obtain a bent tube excellent in corrosion resistance and fatigue resistance by forming compressive residual stress on inner and outer surfaces of bent part of a tube. CONSTITUTION:The tube is heated in longitudinal narrow area, and bending moment is given to the heated area by external force to shift the heated area and the position of action of bending moment. The part just behind the heated area in the direction of shifting is cooled, and compressive force to give compressive residual stress to whole section of the heated area is given to the tube, and bending of the tube is performed. After bending the tube, outer surface of bent part of the tube is heated to high temperature that generates stress exceeding yielding point, and then cooled rapidly. Thus, only compressive residual stress becomes in existence on the outer surface to eliminate tensile residual stress remaining on the outer surface by compressive force.
