更换铜套是工程机械修理中经常碰到的,如能准确计算铜套压入后的收缩量,就能省去铜套压入后二次加工或刮削,提高修理速度和保证修理质量。《工程机械》1980年第四期和1981年第六期均登载了铜套收缩量的计算方法。前者给出的铜套收缩量公式是:
Replacement of copper sleeve is often encountered in the construction machinery repair, such as the exact calculation of shrinkage after the copper sleeve into the press, you can save the copper sleeve pressed into the second processing or scraping to improve the speed of repair and repair to ensure quality. The “Construction Machinery” in 1980 the fourth period and 1981 sixth period are published copper sleeve shrinkage calculation method. The former gives the shrinkage of copper formula is:
