一、概述为了贯彻“有两个积极性,比只有一个积极性好的多”的方针,我厂自1969年至1975年期间,为大力发展地方工业,特别是为农业机械化服务,先后生产了Y3150滚齿机××台;为其他部门协作配套生产了Y3150、Y54及Y5120等齿轮加工机床分度蜗轮副及其他精密蜗轮副共125副。几年以来生产效率、质量逐步提高。蜗轮副已稳定达到JB162-60规定5级精度,接触斑点亦达到标准要求。 I. Overview In order to carry out the principle of “two initiatives, one more positive than one,” I plant from 1969 to 1975, to vigorously develop the local industry, especially for agricultural mechanization, has produced Y3150 gear hobbing machine × × Taiwan; supporting the production of other departments Y3150, Y54 and Y5120 and other gear processing machine indexing worm gear and other sophisticated worm gear a total of 125 pairs. Production efficiency over the past few years, gradually improve the quality. Worm gear has reached the stability of JB162-60 5 level accuracy, contact spots also meet the standard requirements.
