    螺旋輸送機斷軸的內在因素怎么預防

    發布時間:2020-08-25 點擊次數:447
    螺旋輸送機斷軸的內在因素主要包括如下幾個方面:
    The internal factors of the broken shaft of screw conveyor reducer mainly include the following aspects:
    1、減速機設計時軸斷裂處應力過大。
    1、the stress of shaft rupture is too large when the reducer is designed.
    2、減速機輸入軸處軸肩處未細致考慮過渡圓角的曲率半徑和變化曲線使應力集中嚴重發生疲勞破壞。
    2、the curvature radius and the change curve of the transition fillet at the shoulder of the input shaft of the reducer are not carefully considered.
    3、減速機為垂直軸形式,第一級輸入軸為傘齒輪軸,在傘齒輪支承軸承處過渡軸肩處出現較嚴重的應力集中而發生疲勞破壞。
    3、the reducer is in the form of vertical shaft, the first input shaft is the bevel gear shaft, and the more serious stress concentration occurs at the transition shaft of the bevel gear bearing.
    4、減速機為硬齒面減速機,減速機輸入軸直徑較細,雖然計算強度時通過,因軸本身很細,同樣在軸直徑變化處應力集中嚴重并發生疲勞破壞。
    4、reducer for Hardened reducer, reducer input shaft diameter is small, although by calculating the strength, because the shaft itself is very small, in the same shaft diameter changes the stress concentration and serious fatigue failure.
    5、輸入軸的熱處理質量不合格。
    5、input shaft heat treatment quality is not qualified.
