螺旋分級机下轴承原結构(見图1)容易损坏,使用寿命极短,維修工作量和軸承消耗量均較大,是設备本身最薄弱的环节。在1958年曾用巴氏合金軸瓦来代替滾珠軸承,但沒有获得滿意結果。1963年又改为弹簧压力油封軸承,使用效果較好。现将改进情况介紹如下。下軸承改为弹簧压力油封軸承是在原滾动軸承的基础上进行的(見图2)。去掉原結构填料压盖,将
Spiral classifier under the original bearing structure (see Figure 1) is easy to damage, short service life, maintenance workload and bearing consumption are larger, is the weakest link in the device itself. In 1958, babbitt bearings were used instead of ball bearings, but satisfactory results were not obtained. In 1963 it was changed to spring pressure oil seal bearing, the use effect is better. The improvement is introduced below. The lower bearing to spring pressure oil seal bearing is based on the original rolling bearings (see Figure 2). Remove the original structure packing gland, the
