Feeder for transport facilities

TLDR: In this article, the authors proposed to provide a groove on the peripheral part of the body of a feeder made of an electric conductor and to fill a vibration absorber in the groove.

Abstract: PURPOSE:To absorp vibration and prevent a noise, by providing a groove on the peripheral part of the body of a feeder made of an electric conductor and by filling a vibration absorber in the groove. CONSTITUTION:A feeder comprises a feeder body 21 made of an electric conductor of prescribed electric conductivity and a vibration absorber 23 filled in a groove 22 provided on the peripheral part of the body 21. The cross section of the feeder body 21 is shaped as U. A sliding surface 24 for a pantograph shoe is provided on the bottom of the body 21. The groove 22 is located in the body 21. The body 21 is made of iron alloy, aluminum alloy or the like. A solid material such as concrete, a high-molecular substance such as rubber or the like is used as the vibration absorber 23. The feeder is vibrated because a pantograph slides thereon. A solid vibration sound is made by the vibration. Since the vibration energy of the feeder is absorbed by the absorber 23, the magnitude of the vibration is lowered. This results in greatly reducing the solid vibration sound of the feeder itself.
