OIL FEEDER FOR PULLEY TYPE TENSION REGULATOR

摘要

PURPOSE:To scoop up the lubricating oil within an oil tank and automatically feed oil to the rope wire of a pulley by actuating the scooping up member within the oil tank following the revolution of the pulley in the oil feeder for an electric car wiring tension regulator. CONSTITUTION:When an aerial line is expanded and contracted by a night and day temperature difference or the like, a small pulley 9 and a large pulley 10 are revolved forward and backward and draw out or roll in wire ropes 11 and 17 to adjust the tension of the aerial line at a constant level. A follow-up pulley 24 follows up the revolution of this large pulley 10 and revolves a bucket 28. The lubricating oil 41 inside an oil tank 23 is scooped up by the bucket 28 and the lubricating oil that flows from the through hole 29 of the bucket 28 is received by means of a saucer 32 and then oil is fed to the rope wires 11 and 17 of the large and small pulleys 10 and 9 from an outlet hole 34 through oil supply pipes 35 and 36.
