電動推桿由驅動電機(ji)、減速齒輪、螺(luo)桿、螺(luo)母、導(dao)套(tao)、推桿、滑座、彈簧(huang)、外殼及渦輪、微動控制開關等組成。

電(dian)動(dong)推(tui)桿是一種新(xin)型(xing)的電(dian)動(dong)執行(xing)(xing)機(ji)構，電(dian)動(dong)推(tui)桿主要(yao)由電(dian)機(ji)、推(tui)桿和控(kong)制裝置等機(ji)構組成的一種新(xin)型(xing)直(zhi)線執行(xing)(xing)機(ji)構，可以實現遠距離控(kong)制、集中控(kong)制。電(dian)動(dong)推(tui)桿在(zai)(zai)一定(ding)范圍行(xing)(xing)程(cheng)內作(zuo)往返運動(dong)，一般電(dian)動(dong)推(tui)桿標準行(xing)(xing)程(cheng)在(zai)(zai)，100，150，200，250，300，350，400mm，特殊(shu)行(xing)(xing)程(cheng)也可根(gen)據(ju)不同應用(yong)條件要(yao)求(qiu)設計定(ding)做。
