我厂铸造车间有两台 S116混砂机,在长期使用过程中维修非常频繁,影响了生产。主要问题是:主轴下端大圆锥齿轮与传动横轴的小圆锥齿轮的啮合只靠一个轴承座支承,属半轴单支承结构。长期生产实践证明,只用一个轴承支承,承受力不够,因此导致铜瓦严重受热,磨损快,噪声越来越大,最后无法运行。针对以上情况,我们对 S116混砂机的传动部分进行了改进,见下图所示。将半轴单支承 I plant casting workshop has two S116 sand mixer, the maintenance of long-term use of the process is very frequent, affecting the production. The main problems are: the bevel gear at the lower end of the main shaft and the bevel gear on the horizontal axis of transmission are supported by only one bearing seat, which belongs to a single support structure with a semi-shaft. Long-term production practice has proved that only one bearing support, bearing capacity is not enough, resulting in severe heating of copper tiles, wear fast, more and more noise, and finally unable to run. In view of the above situation, we have improved the transmission part of S116 sand mixer, as shown below. Will be a single axle bearing
