thus, the synchronous belt span length is the key designing parameter in timing-transmission mechanism design 因此,在進行發(fā)動機正時傳動機構(gòu)結(jié)構(gòu)設(shè)計時,同步帶類型確定后,其跨度大小是設(shè)計的關(guān)鍵。
because the area is fixed, you can always find the span length of the x axis and the span height of the y axis 因為該區(qū)域是固定的,所以您總是可以找到x坐標軸的跨度(長度)和y坐標軸的跨度(高度)。
the study shows that shortening the span length can effectively reduce the transverse vibration amplitude of synchronous belt and can avoid possible resonance region of synchronous belt 結(jié)果表明,減小同步帶跨度既可以有效減小同步帶運動過程中橫向振動幅度,又可以使同步帶運動有效避開正時傳動機構(gòu)可能的共振區(qū)。
