从JD-1调度绞车的装配工序图可以看出:10-3-503齿轮架和10-3-601大齿轮架是两大主要零件,它们与滚筒的配合H8/R6均为过渡配合,装配精度要求相当高,以往采用人工抡大锺装配,劳动强度很大,装配效率低,一次装配合格率85%。2002年我们对19台调度绞车进行了调查分析,见表1。从调查表 From JD-1 scheduling winch assembly process can be seen: 10-3-503 gear carrier and 10-3-601 gear carrier is the two major components, and their drum with the H8 / R6 are transition fit, assembly Accuracy requirements are quite high. In the past, artificial workers were used to assemble large work loads. The labor intensity was high and the assembly efficiency was low. The qualified rate of an assembly was 85%. In 2002 we conducted a survey of 19 dispatch winches, as shown in Table 1. From the questionnaire
