国产W100(1/2)挖掘机转台多为焊接件,其具体结构参看原图102-1-1E。正铲挖掘时,整个机身向前倾斜,转台后部的两个平衡勾滚(图号:102-1-10)受力,两平衡勾滚与机身回转大齿圈(图号:101-2-3B)的下部工作面接触,使机器保持平衡。此时,机器重心在前,由转台前部的七个滚轮(图号:101-3-3)支承。卸载时,机器重心由前至后,将会产生瞬时冲击力。反力通过滚轮传至部分
The domestic W100 (1/2) excavator turntables are mostly welded pieces, the specific structure of which is shown in the original figure 102-1-1E. When shovel is digging, the entire body is tilted forward, and the two balance hooks (drawing number: 102-1-10) at the rear of the turntable are subjected to force, and the two balance rollovers and the turning gear ring of the body (drawing number: 101 -2-3B) Touch the lower face to keep the machine balanced. At this point, the center of gravity of the machine is at the front and supported by the seven rollers (picture number: 101-3-3) at the front of the turntable. When unloading, the center of gravity of the machine from front to back, will have a momentary impact. React to the part through the scroll wheel
