集材—50拖拉机的车架,使用中很容易出现变形、裂纹及装置件紧固螺栓松动等现象,引起驾驶室早期损坏,最终减速器齿轮打齿、轴承提前报废,至使拖拉机有效功率明显降低。集材—50拖拉机作业条件恶劣,常在倾斜的凸凹不平的路面上做频繁的急转弯,受到较大的冲击振动,由此而产生的地面反作用力要由车架来承受。当多次重复出现的应力超过了材料疲劳极限或较大的应力超过了材料的屈服极限时,车架 Skidding -50 tractor frame, it is easy to use in the deformation, cracks and device fastening bolts loosening, etc., causing the cab early damage, the final reducer gear teeth, bearings scrapped in advance, so that the effective power tractor significantly reduce. Skidding-50 Tractor operating conditions are poor, often in the inclined uneven surface make frequent sharp turns, subject to greater shock and vibration, resulting from the ground reaction to the frame to withstand. When repeated stress exceeds the material fatigue limit or greater stress exceeds the yield limit of the material, the frame
