摘　　要：牵引架球头作为平地机整个工作装置活动的支撑部位,在工作负荷大或润滑方式不当的情况下极易出现故障。针对一起球头断裂的故障案例,通过对结构强度、材料性能、装配工艺等方面进行分析,找出装配工艺不当使球头间隙调整不到位是球头断裂的关键原因,并提出有效改进措施。经市场验证,改进后球头使用寿命及可靠性显著提高。The drawbar ball,as the support part of the entire equipment of the grader,is prone to fault under heavy workload or improper lubrication.Based on a fault case of ball fracture,by analyzing the structural strength,material properties and assembly process,it is found that the key cause of ball fracture is the improper assembly process resulting in inappropriate adjustment of the ball clearance,and effective improvement measures are proposed.it is verified in the market that the service life and reliability of the improved ball are significantly enhanced.
