Abstract : a new type cold frame is intruduced. the deformation of unsymmetry section steel after cooling is mainly eliminated by reversely curring it on line, ensuring the achievement of automation of meticulous repair. at the same time the disposing principle of equilibrium weight on the driving axis of cold frame drived by eccentric wheel was improved. the torsional moment of transmission shaft and power of electric motor are reduced by the method
文摘:介紹了一種新型冷床，通過在線對非對稱型鋼進行反向彎曲，基本上消除了非對稱型鋼冷卻后的變形，保證了精整工序自動化的實現.同時，提出了偏心輪驅動的冷床驅動軸上平衡重的配置原則.此方法可降低傳動軸上所受的扭矩，減少了電動機的功率On the basis of 3d modeling and virtual prototyping technology and energy saving transformation method for parameterized simulation moving beam typed oil suction pump, and using the eccentric gear reducer to replace the ordinary gear reducer to let the driving radius of eccentric gear be kept a variation of similar tendency with the load of crank in order to improve load property of the motor, thus raised the working efficiency of the entire oil suction pump and achieved the effect of energy saving
摘要基於三維建模和虛擬樣機技術，參數化模擬游梁式抽油機節能改造方法，用偏心齒輪減速器代替普通齒輪減速器，使偏心齒輪驅動半徑和曲柄負載保持同趨勢變化，以改善電機負載特性，提高整個抽油機的工作效率，達到了節能的效果。It can also determine the fault spot and reason. this technology has been used in some technological fields and proved efficient. it has promoted the revolution of maintance system and the historial protection is replaced by preventive maintenance. with this technology, we can improve the reliability of machine and decrease the maintance fee. recently, reserch has pick up a fervent pace in the area of fault diagnosis of electrical machines. the paper simply analyzes the fault reason of electrical machines, stressly describes and explores the methods of condition monitoring and fault diagnosis such as partial discharge, stator current, rotating speed, vibration etc. fault prognosis is now include diagnostic feature, reason, spot. prodigious improvement in signal processing hardware and software has made this possible. primarily, these techniques depend on locating specific harmonic components of the fault. these harmonic components are usually diffirent for diffirent types of faults. automated tools such as fuzzy logic based system is also simply presented in the paper
