guide bearing 【機械工程】導引軸承。

guide board

Second , adopting the linearity of oil film of the guide bearings , the transient response of the shafts is computed and analysis by integrating with willson method . because of the uncertain position of the shafts in the guide bearing , the model and solution method of nonlinear transient response of the shafts is discussed 然后結合willson數值積分法,采用線性化油膜力,對機組軸系的線性瞬態響應進行了計算分析,根據機組軸系在瞬態響應中運動的不確定性,給出了由導軸承油膜力非線性所引起的主軸系統的非線性瞬態響應的建模及求解方法。

Thirdly , the correlative coefficient is computed between the pressure fluctuation signal of draft tube and the displacement signal of upper guide bearing , the thrust bearing and the head cover , with this the conclusions on the shafts response due to pressure surge in 并與模型尾水管壓力脈動試驗結果進行對比?結合流動仿真試驗以及動力特性計算結果,全面分析?評定機組的實際運行狀況,劃定運行區域,為電站合理調度

First , the system boundary of machines affecting the shafts , such as the guide bearings , seal , electrical and hydraulic forces , the water in the runner etc , is analyzed . and the mathematic model of the system boundary of the machine is built 本文首先分析了對機組主軸系統影響較大的系統邊界條件,如導軸承、水封、電磁拉力、轉輪處的水體等,并分別建立了它們的數學模型。

Production and application of thrust bearing , and guide bearing made of filled ptfe in submarine motor pump are introduced 介紹了潛水泵中止推軸承與導向軸承用填充聚四氟乙烯材料進行的生產和應用。
