一、前言为适应开发矿业的需要,矿井提升机的提升能力有了较大的提高(比仿苏老产品提升机的提升能力提高20～60％,提升速度提高20％左右)若仍用渐开线软齿面的齿轮,减速器的重量和体积必然很大。为了满足提升能力提高的要求,采用了圆弧齿形的减速器,不但满足了要求,较渐开线减速器的重量还有减少,表1举例说明。洛阳矿山厂自一九五八年试制第一台圆弧齿轮减速器以来,到六五年前为第一阶段,这一段共试制了卅多台,主要作提高承载能力减轻重量的试验,使用了不同的齿形和参数,是
I. Preface In order to meet the needs of developing mining industry, the improvement capability of mine hoist has been greatly improved (20 ~ 60% higher than that of the hoisting machine of Su-like product and 20% increase speed) Open soft-tooth surface gear, reducer weight and size must be great. In order to meet the requirements of improving the lifting capacity, the use of arc-shaped gear reducer, not only to meet the requirements, the weight of the involute reducer still less, Table 1 illustrates. Since the trial production of the first circular arc gear reducer in 1958, Luoyang Mine Plant has been the first stage six to five years ago. A total of more than one units were trial-built in this section. The main purpose of this trial was to increase carrying capacity and reduce weight. Different teeth and parameters, yes
