1981年我院为无锡县外贸公司蚕茧仓库设计了一台干茧包提升机。经江苏吴县通用机械厂制造,于1982年5月安装在无锡县外贸公司石塘湾仓库。6月份投入使用,效果良好。这台提升机主要包括五部分,如图1所示。第一,驱动装置。由电动机、摆线减速器、十字滑块联轴器、主动链轮和棘轮逆止器组成。其中减速器型号为BWED 270×150-1.1-17×17,链轮齿数Z=8,节距t=200毫米。第二,中间架。由四根不等边角钢组成矩形断面,又兼作片式牵引链中滚轮的导轨。第三,链条。提升机采用片式牵引链,链的类 In 1981, our hospital designed a dry cocoon package elevator for the cocoon warehouse of Wuxi Foreign Trade Company. By Jiangsu Wuxian General Machinery Factory manufacturing, in May 1982 installed in Wuxi County Shitangwan foreign trade company warehouse. Put into use in June, the effect is good. This hoist mainly includes five parts, as shown in Figure 1. First, the drive. By the motor, cycloidal reducer, cross slide coupling, drive sprocket and ratchet backstop components. Which reducer model BWED 270 × 150-1.1-17 × 17, the number of sprocket Z = 8, pitch t = 200 mm. Second, the middle frame. Rectangular section by the four unequal angle of the composition, but also double as the film chain traction roller track. Third, the chain. Lifting machine using chip traction chain, chain of categories
