Description
(b) 場合によっては上記の測定した半径方向所定位置からの偏差から比較量を求めるステップと、
(c) ステップ(a)で測定した半径方向所定位置からの偏差またはステップ(b)で形成した比較量と、あらかじめ定めた境界値と比較するステップとを有する。
Claims (13)
- 例えば混練器のシャフトであるシャフトの曲げを監視する方法において、
前記のシャフトは少なくとも片側が支承されており、
前記の方法はつぎのステップ、すなわち、
(a) 支承部とは異なる少なくとも1つのシャフト位置において、半径方向所定位置からのシャフトの偏差を測定するステップと、
(b) 場合によっては前記の測定した半径方向所定位置からの偏差から比較量を求めるステップと、
(c) ステップ(a)で測定した半径方向所定位置からの偏差またはステップ(b)で形成した比較量と、あらかじめ定めた境界値と比較するステップとを有することを特徴とする、
シャフトの曲げを監視する方法。 - 測定のために円周方向に互いにずらした少なくとも2つのセンサを使用して、半径方向所定位置からの偏差の方向を検出する、
請求項1に記載の方法。 - まずシャフトに負荷をかけずに、半径方向所定位置からのシャフトの偏差を測定する、
請求項1または2に記載の方法。 - 前記のステップ(b)で形成する比較量は、シャフトに負荷かけずに測定した半径方向所定位置からの偏差と、シャフトに負荷をかけて測定した偏差との差の絶対値である、
請求項3に記載の方法。 - 前記の少なくとも2つのセンサによって検出した半径方向所定位置からの偏差または前記の比較量を軌跡図にあらわす、
請求項2から4までのいずれか1項に記載の方法。 - 前記の半径方向所定位置からの偏差と比較する前記の境界値は、前記の軌跡図における包絡線を形成する、
請求項5に記載の方法。 - 前記の境界値を、シャフトの最大許容曲げから求める、
請求項1から6までのいずれか1項に記載の方法。 - 前記の境界値は、シャフトに負荷をかけていない際の半径方向所定位置からの偏差と、最大許容偏差とから得られる差の絶対値である、
請求項7に記載の方法。 - 前記の境界値を上回った場合、シャフトを停止する、
請求項7または8に記載の方法。 - 前記の境界値に達するかまたは上回った場合、固体含量を低減するか、固体の添加物またはリサイクルされる微粒材料を少なくするか、温度を低下させるか、生成物の架橋度を変化させるか、少なくとも1つの離型剤を添加するか、または温度を上昇させる、
請求項7または8に記載の方法。 - 前記のシャフトの円周位置を検出する、
請求項1から10までのいずれか1項に記載の方法。 - 前記のシャフトの円周位置を検出するため、センサによって検出されるマークを付ける、
請求項11に記載の方法。 - 前記の半径方向所定位置からの偏差をうず電流センサによって求める、
請求項1から12までのいずれか1項に記載の方法。
