决定旋转刮刀工作性能有两个因素:一是刮刀轨迹的重复周期(决定刮到性能的好坏);一是刮刀对球盘底的清理周期(决定清理能力的大小)。二者取决于刮刀的三个参数。刮刀转速n_2(n_2/n_(?)),刀头个数a,刀头宽成b。利用轨迹图谱分析法,可以确定它们之间的数学关系。在一定数值范围内,重复周期愈长,刮到性能愈好。但是,重复周期的无限增长。反而会削弱其刮到性。清理周期愈短,清理效果愈好,但是,过于缩短清理周期,将增加刮刀传动功率。本文探讨了二者的合理取值范围。
Determining the working performance of the rotating blade has two factors: one is the repetition cycle of the blade trajectory (which determines the performance is good or bad); the other is the cleaning cycle of the blade against the bottom of the ball (which determines the size of the cleaning capacity). Both depend on the three parameters of the blade. Blade speed n_2 (n_2 / n_ (?)), The number of a cutter head wide b. Using trace analysis, you can determine the mathematical relationship between them. Within a certain range of values, the longer the repetition period, the better the performance. However, the unlimited growth of repetitive cycles. But will weaken it to scratch. The shorter the cleaning cycle, the better the cleaning effect, however, too short the cleaning cycle will increase the scraper drive power. This article explores the reasonable range of the two.
