Abstract
Sistema óptico detector de esfuerzos mecánicos el dispositivo que desarrolla el sistema reivindicado, comprende: Dos placas o discos enfrentados, vinculados uno (1) al eje motor (3) y el otro (2) al piñón (4), cuyas características pueden ser, alternativamente: los dos translúcidos o transparentes, con marcas opacas (5) radiales y periféricas; los dos opacos, con perforaciones periféricas; uno translúcido o transparente y el otro reflectante, ambos con marcas opacas periféricas; y uno opaco y el otro reflectante, ambos con perforaciones periféricas; Resortes (6) que vinculan el eje motor (3) y el piñón (4) y un equipo (7) emisor-receptor de energía luminosa. Cuando se realizan esfuerzos mecánicos por el eje motor (3), se produce un desplazamiento angular relativo de los discos (1)-(2), a causa de la holgura existente en la chaveta (8) de enclavamiento del piñón (4) al eje motor (3), interceptándose el paso o reflexión de la luz a través de los discos, al quedar intercaladas las marcas (5) olas perforaciones. Cuando se reduce suficientemente el esfuerzo, los resortes (6) devuelven los discos (1)-(2) a su posición de reposo, con lo, que vuelven a ser permeables a la luz. Las alternancias entre paso e interceptación de la luz, son registradas por el equipo (7).Optical system for detecting mechanical stresses the device that develops the claimed system, comprises: Two plates or discs facing each other, linked one (1) to the drive shaft (3) and the other (2) to the pinion (4), whose characteristics can be, alternatively: both translucent or transparent, with opaque (5) radial and peripheral marks; the two opaque, with peripheral perforations; one translucent or transparent and the other reflective, both with peripheral opaque markings; and one opaque and the other reflective, both with peripheral perforations; Springs (6) that link the motor shaft (3) and the pinion (4) and a light emitter-receiver equipment (7). When mechanical efforts are made on the drive shaft (3), there is a relative angular displacement of the discs (1) - (2), due to the clearance in the pinion key (8) of the pinion (4) to the motor shaft (3), intercepting the passage or reflection of light through the discs, when the marks (5) are perforated waves. When the stress is sufficiently reduced, the springs (6) return the discs (1) - (2) to their resting position, thereby, becoming again permeable to light. The alternations between passage and interception of the light are registered by the equipment (7).
