中原内燃机配件厂是国内气缸套生产量最大的厂家,1987年开始使用鳞板输送机。在使用过程中经常出现小滚轮脱轨或卡死现象,影响生产正常进行,以致在1992年初因问题太大而被迫停用。为此,对输送机进行以下三方面改进(见下图):①鳞板输送机的鳞板原为槽体型,模具冲压成型后整体焊接而成,制造复杂,成本高,每块125元。现改成平板式,制造简单,每块成本仅为14元,且不容易损坏。②传动牵引部分原为链轮与链条轴传动,链条轴本身不转动,使链轮与链条轴磨损快,四年
The Central Plains Engine Parts Factory is the largest manufacturer of cylinder liner production in 1987, began using slat conveyor. In the course of the use of small rollers often appear derailed or stuck phenomenon, affecting the normal production, resulting in early 1992 because of the problem is too large and forced to disable. To this end, the conveyor to improve the following three areas (see below): ① Slab conveyor scale was originally a tank-type, the overall shape of the die after stamping welded together, manufacturing complex, high cost, each 125 yuan. Now changed to flat, easy to manufacture, each cost only 14 yuan, and not easy to damage. ② traction part of the original drive chain and chain drive shaft, the chain itself does not rotate the shaft, the sprocket and the chain shaft wear fast, four years
