我厂φ76无缝钢管穿孔机是六十年代投产的老设备。传动机构的万向联轴器一直是薄弱环节。曾经采用的铜滑块式和十字型万向联轴器都不能满足生产需要,作业率低,检修频繁,配件消耗快,拆卸装配都不方便。 1982年开始采用浙江重型机械配件厂生产的ZKφ350十字型万向联轴器。由于设备陈旧,工作冲击载荷较大,以及超负荷运转等,联轴器的604714 T滚柱轴承损坏很快。仅83年2～3月就被迫停机更换了21个轴承。后来,我厂将604714T滚柱轴承改为填充MC尼龙套,经生产使用,寿命可达3个月。从而保证了生产的正常进行,大大降低了生产成本,减少了停机时间,提高了设备作业率,减轻了维修工人的劳动强度。其经济效益按穿孔机平均作业率为50％计算,可增加年产值九万余
I plant φ76 seamless steel pipe piercing machine is put into operation in the sixties of the old equipment. Transmission coupling universal coupling has always been the weak link. Have used the copper slider and cross-type universal coupling can not meet the production needs, low operating rates, frequent maintenance, parts consumption, demolition assembly is not convenient. 1982 began using Zhejiang Heavy Machinery Parts Factory production ZKφ350 cross-type universal coupling. Due to outdated equipment, work load impact and overload, etc., the coupling of the 604714 T roller bearings damaged quickly. Only 83 years from February to March was forced to shut down replaced 21 bearings. Later, I plant to 604714T roller bearing filled with MC nylon sleeve, the production and use, life expectancy of up to 3 months. So as to ensure the normal production, greatly reducing production costs, reducing downtime and improve equipment operating rates and reduce the labor intensity of maintenance workers. Its economic efficiency according to the average operating rate of puncher 50%, can increase the annual output value of more than 90,000
