为提高工地机械化水平,加速社会主义建设,我厂试制1米~3梨形混凝土搅拌机。该机结构简单、性能良好,减速机采用了 XW7.5-5-1/17型行星摆线针轮减速机(见图1)。这种减速机精度要求较高,一度成为生产关键。我厂职工遵照毛主席关于“自力更生”、“奋发图强”的教导,土法上马,土洋结合,利用现有设备,攻下这一难关。现将主要零件加工及工装简介如下。一、摆线齿轮的加王摆线齿轮(见图2)的加工是减速机最重要的环节。我厂根据现有条件,将齿轮材料由GCr15轴承钢改用18 CrCoTi 氮化钢。
In order to improve the mechanization level of the site and speed up the construction of socialism, I plant trial production of 1m ~ 3 pear-shaped concrete mixer. The machine structure is simple, good performance, reducer using XW7.5-5-1 / 17 planetary cycloid reducer (see Figure 1). This reducer high precision, was the key to production. In accordance with Chairman Mao’s teachings on “self-reliance” and “striving for excellence”, our factory workers took the lead in using indigenous methods and using existing equipment to capture this difficult situation. Now the main parts processing and tooling are as follows. First, cycloid gear plus king cycloid gear (see Figure 2) is the most important part of the reducer. I plant under the existing conditions, the gear material from GCr15 bearing steel to 18 CrCoTi nitride steel.
