monotonic quantity 中文意思是什麼
monotonic quantity
解釋
單調函數-
2, the friction coefficient at the pitch point is not a monotonic quantity of the rational speed or the load, instead of having a maximum value. and the value of the friction coefficient is very small, its order of magnitude only being 10 - 3. so, it is reasonable that the friction force on teeth surfaces are ignored when the gear - driven contact fatigue strength is designed
2 、當輪齒在節點嚙合時,隨著轉速或載荷的變化,齒面摩擦系數並非呈單調變化,而是存在極值點;節點嚙合處的齒面摩擦系數很小,其數量級為10一, ,因此在做齒輪強度設計時,忽略齒面摩擦力的影響是有理論根據的。
