我车间有四台S116辗轮式混砂机,使用过程中,轮柄轴轴端上紧固轴端挡圈的螺栓经常发生断裂,使轮柄脱离轮柄轴。原来的绪构如图1所示。它通过两只M14的六角头细牙螺栓8把轴端挡圈7紧固在轮柄轴5上,防止轮柄从轮柄轴上脱出。螺栓8用钢丝9穿入六角头防止松动。由于轴端六角头螺栓受力大,经常断裂,既不安全,又影响了正常生产。因此我们对轮柄轴结构和紧固方法进 My workshop has four S116 rolling wheel sand mixer, the use of the process, the handle shaft end of the fastening shaft end of the ring bolts often break, so that the wheel handle off the handle shaft. The original thread structure shown in Figure 1. It uses two M14 hexagonal head bolt 8 to fasten the end ring 7 to the handle 5 to prevent it from coming off the handle. Bolt 8 with wire 9 into the hexagonal head to prevent loosening. Due to the shaft hexagonal head bolt force, often broken, neither safe, but also affect the normal production. Therefore, we handle the shaft structure and fastening methods into
