The paper research a predominant variable torque clutch ? hyperboloid clutch with rollers . the clutch makes convert mutually between force and torque reality to control transmission with special geometry relation and friction transmission . it is satisfy with the request of modern industry 本文所研究的是一種性能優(yōu)越的可變扭矩加載器?雙曲面滾柱加載器,利用加載器接觸表面特殊幾何關(guān)系,通過接觸表面的摩擦傳動(dòng),實(shí)現(xiàn)軸向力與轉(zhuǎn)矩之間的相互轉(zhuǎn)換,從而達(dá)到控制制動(dòng)和傳遞動(dòng)力的目的,可滿足現(xiàn)代工業(yè)對加載裝置的要求。
Based on the torque - speed characteristic curve of induction motors , analyses were done on changes in slip with an variation in frequency when an induction motor drives different kinds of loads , including those with constant torque , constant - maximum torque , variable torque ( except fans and pumps ) and constant power , as well as fans and pumps , the formulas to calculate the slip and the speed under different frequencies and loads were presented 摘要以異步電動(dòng)機(jī)機(jī)械特性曲線為基礎(chǔ),分析了變頻調(diào)速異步電動(dòng)機(jī)在拖動(dòng)恒轉(zhuǎn)矩負(fù)載、恒最大轉(zhuǎn)矩負(fù)載、變轉(zhuǎn)矩(非風(fēng)機(jī)和泵類)負(fù)載、恒功率負(fù)載以及風(fēng)機(jī)和泵類負(fù)載時(shí),轉(zhuǎn)差率隨頻率變化的規(guī)律。
