摘要
设计一种除屋檐冰棱机,由主运动的偏置曲柄滑块机构、控制升降的"X"型杆机构组成。根据给定行程速比系数K、偏距e、滑块行程H设计偏置的曲柄滑块机构,得出运动尺寸,即曲柄长度a和连杆长度b。分析主运动机构的运动特性,判断行程速比系数为K、速度波动是否满足条件,分析主运动机构的等效动力学模型,得出等效构件曲柄的等效力矩和等效转动惯量。
Designed in addition to the eaves ice machine, it consists of an offset crank mechanism with main motion and an "X" rod mechanism that controls lifting. According to the crank stroke mechanism designed to give a stroke ratio coefficient K, offset e, and stroke H, the motion size, that is, the crank length a and the link length b are obtained. Analyze the motion characteristics of the main motion mechanism, and determine whether the speed ratio coefficient is K and whether the speed fluctuation meets the condition. The equivalent dynamic model of the main motion mechanism is analyzed, and the equivalent moment and equivalent moment of inertia of the equivalent component crank are obtained.
