制(zhi)(zhi)動(dong)(dong)器的選(xuan)擇根本的因素，應(ying)考慮(lv)制(zhi)(zhi)動(dong)(dong)器的使(shi)用要求和制(zhi)(zhi)動(dong)(dong)器的工作(zuo)(zuo)條件，以及(ji)制(zhi)(zhi)動(dong)(dong)器的制(zhi)(zhi)動(dong)(dong)轉(zhuan)矩(ju)大小。 (1)要認真分析所(suo)需應(ying)用的制(zhi)(zhi)動(dong)(dong)器的工作(zuo)(zuo)性質和工作(zuo)(zuo)條件，根據實際工作(zuo)(zuo)狀況選(xuan)用閉式或開式類(lei)型。 (2)
制(zhi)(zhi)動是研(yan)制(zhi)(zhi)大(da)功率下運(yun)帶式(shi)輸送機的主要技術關鍵問題之一，制(zhi)(zhi)動器在制(zhi)(zhi)動時所(suo)吸收的能量比水平和上運(yun)輸送機大(da)得多，若單純使用機械(xie)抱閘(zha)，閘(zha)襯(chen)磨損快(kuai)，易造成飛車事故(gu)。閘(zha)輪表(biao)面溫度高，甚(shen)至與閘(zha)襯(chen)磨損產生(sheng)火(huo)花，會
制動(dong)(dong)(dong)器(qi)是具(ju)有使運(yun)動(dong)(dong)(dong)部件(jian)(或運(yun)動(dong)(dong)(dong)機(ji)械)減速(su)、停(ting)(ting)止或保持(chi)停(ting)(ting)止狀態等(deng)功(gong)能的裝置。是使機(ji)械中的運(yun)動(dong)(dong)(dong)件(jian)停(ting)(ting)止或減速(su)的機(ji)械零件(jian)。俗稱剎車、閘。制動(dong)(dong)(dong)器(qi)主要由制架、制動(dong)(dong)(dong)件(jian)和(he)操縱裝置等(deng)組成(cheng)。有些(xie)制動(dong)(dong)(dong)器(qi)還裝有制動(dong)(dong)(dong)件(jian)間隙
