摘要
成都无缝钢管厂周期式轧管机是五十年代由国外引进的,投产二十多年来,随着轧管机产量、钢种、规格的不断扩大,轧管机压下螺丝及其传动装置已成为薄弱环节。本文应用概率统计理论对压下螺丝的强度及稳定性进行可靠性计算,为使用和改造提供一种计算依据,同时也可作为同类设备设计参考。
The pilger mills in our plant were introduced from abroad in 1950s. Some critical problems occurred to the screwdown devices and drives of the mills during more than 20 years' operation with the outputs, steel grades and specifications gradually increased and expanded. Reliable strength and steadiness of the screwdown devices are calculated with the probabilistic-statistic theory to provide references for the application, modification of the mills and also for designs of the same units.
