江苏省P县肉联广,1984年旺季生产前,发现原来装有轴承的挂猪滚轮无法使用,只能忍痛报废此种滚轮三千多套。及时采取突击加工,添置了三千多套原来那种不装轴承的滚轮,走了回头路。 P县肉联厂为什么会发生这样的“事故”呢?兄弟单位是否也有类似情况? 对挂猪滚轮材质与结构有必要进行探讨。从一般情况看,任何滚动部件,安装上滚动轴承,总会感到运转轻松。但从辩证的方法进行分析,任何事物,都应该考虑使用要求,场所环境以及材质、结构和性能。挂猪滚轮实际运行速度每分钟不超过20米,滚轮转速每分钟
P County, Jiangsu Province, UF wide, 1984 season before the production and found that the original bearing hanging pig wheel can not be used, only reluctantly scrapped this wheel more than 3000 sets. Timely take surprise processing, acquired more than three thousand original sets of the wheel does not install bearings, walked back. P County Roulian Chang why happen to such an “accident”?

Hanging pig wheel running speed of not more than 20 meters per minute, wheel speed every minute
