由机械电子工业部第二装备司主持召开的《带式输送机用垂直轴减速器系列》鉴定会和《运输机械用圆锥圆柱齿轮减速器标准》审查会,于1989年5月中旬在唐山市召开.会上,《带式输送机用垂直轴减速器系列》通过了部级鉴定.与会代表一致认为该项新型的六级精度的渗炭淬火齿轮减速器系列是先进的,技术上达到了国外先进的同类型减速器80年代产品水平,能够满足胶带输送机的配套需要.系列提供的DBY型和DCY型硬齿面减速器,与原使用的ZQ型和ZL型软齿面减速器比较,具有承载能力高、寿命长、占地面积小、重量轻等优点,经济效益显著.DBY(二级)、DCY(三级)型硬齿面垂直轴减速器系列有15种中心距、16种速
Appraisal meeting of “Vertical Axis Reducer Series for Belt Conveyor” and “Review Criteria for Cone Cylindrical Gear Reducer for Transportation Machinery” chaired by the Second Equipment Division of the Ministry of Machinery and Electronic Industry were held in Tangshan in mid-May 1989 Held at the meeting, “the vertical conveyor belt conveyor series” passed the ministerial level identification.The participants agreed that the new six-precision carburizing quenching gear reducer series is advanced, technically reached The advanced type of the same type of reducer in the 1980s product level to meet the matching needs of the belt conveyor DBY series and DCY series of hardened reducer provided with the original ZQ type and ZL soft tooth reducer , Has the advantages of high carrying capacity, long life, small footprint, light weight, etc., and has obvious economic benefits. There are 15 types of center distance in the series of DCY (three-stage) Seed speed
