胶块联轴器有良好的性能,故广泛地用于中小型磨机。我厂生产的φ1.83×6.4m和φ2.2×6.5m两种磨机都采用这种联轴器。但在制造和使用中,发现有两个问题要解决。首先,镶嵌胶块的固定半联轴器,铸造废品率在35％以上,即使用上了,也有相当一部分是降格使用。其次,胶块容易磨损,固定半联轴器的凹槽在圆周上分布越不均匀,每个胶块受力差异就越大,磨损也越大。有的胶块,使用不久就得更换。
Plastic block coupling has good performance, it is widely used in small and medium-sized mill. I produced the factory φ1.83 × 6.4m and φ2.2 × 6.5m both kinds of mill are used in this coupling. However, in the manufacture and use, two problems were found to be solved. First of all, the fixed half of the plastic mosaic coupling, casting scrap rate of 35% or more, even if used, but also a considerable part of the downgrade use. Secondly, the plastic block is easy to wear, the groove of the fixed semi-coupling is unevenly distributed on the circumference, the bigger the difference of the force is and the bigger the wear is. Some plastic blocks, use soon have to be replaced.
