经过计算分析,活塞杆弯曲的原因是动臂油缸的两端与机架和动臂一起倾斜,支撑宽度过小,表明装配调整间隙不合适。或侧面磨损严重,应增加支撑宽度;沉积物在缸体下端的积累和动臂缸下端的磨损表明,沉积物已严重积累,旋转摩擦较大。
Through calculation and analysis, the reason of piston rod bending is that both ends of boom cylinder incline together with the frame and boom, and the support width is too small, which indicates that the assembly adjustment clearance is not appropriate. The accumulation of sediment in the lower end of the cylinder block and the wear of the lower end of the boom cylinder show that the deposit has accumulated seriously and the rotary friction is large.
改进措施包括:
Improvement measures include:

1.增加支撑宽度。通常,支撑宽度是活塞杆直径的1.2到1.5倍。
1. Increase the support width. Generally, the support width is 1.2 to 1.5 times the diameter of the piston rod.
2.在组装过程中,请充分利用调节垫,以确保动臂油缸两端与机架和动臂之间的间隙和对齐,并提高调节垫材料的耐磨性。
2. In the assembly process, make full use of the adjusting pad to ensure the clearance and alignment between the two ends of the boom cylinder and the frame and boom, and improve the wear resistance of the adjusting pad material.
3.完善排放结构;增加开孔距离H1和出料板的倾斜角度α,减少毛坯的堆积,有利于物料的顺利出料。增加动臂油缸下端对主机的排放。距离H2是为了促进大尺寸石头的排出。
3. Improve the discharge structure; increase the opening distance H1 and the inclined angle α of the discharge plate to reduce the accumulation of blanks, which is conducive to the smooth discharge of materials. Increase the discharge of the lower end of boom cylinder to the main engine. The distance H2 is to facilitate the discharge of large-sized stones.
4.说明手册规定了定期积聚的物料的要求。改进后,活塞杆不再弯曲。
4. The instruction manual specifies the requirements for periodic removal of accumulated materials. After improvement, the piston rod is no longer bent.
