硬塑真空挤出机下级减速器减速比的选择

Choice of reduction ratio for the reducer in lower still-extruder

论述了硬塑真空挤出机下级减速器减速比的计算,并对几种不同减速比的减速器进行比较,提供了合理的减速比数值。

The article describes the calculation of reduction ratio for the reducer in lower still-extruder,and compares the reducers in different reduction ratio,finally shows the rational reduction ratio.
