日本名古屋钢厂在输送钢板的辊道上，采用一种新型辊来取代原铁辊，使噪声从１１０ｄＢ降至８４ｄＢ。这种新型辊道由橡胶辊环和树脂辊环相互间隔组成辊身。为使辊身磨损后便于更换，将辊身与辊轴设计成套合结构，容易拆装。并使橡胶辊环直径略大于树脂辊环。使用时，噪声大的 Nagoya Steel Works, Japan, used a new type of roller to replace the original iron roller on the roller conveyors to reduce the noise from 110 dB to 84 dB. This new roller is composed of a rubber roller ring and a resin roller ring spaced apart from each other to form a barrel. In order to make the roller body easy to replace after being worn, the roller body and the roller shaft are designed as a nested structure, which is easy to disassemble and assemble. And the rubber roller ring diameter slightly larger than the resin roll ring. When used, the noise is large
