液壓制動器(qi)結構特點

1、結構(gou)緊湊 失(shi)電(dian)制(zhi)(zhi)動器軸(zhou)向尺寸雖小，但制(zhi)(zhi)動扭矩足夠大。

2、響應(ying)迅速(su) 失電制(zhi)(zhi)動(dong)器是(shi)采用彈簧裝置(zhi)形成(cheng)制(zhi)(zhi)動(dong)扭矩，彈簧復位時間即為制(zhi)(zhi)動(dong)響應(ying)時間

3、壽命長(chang)久 失電制動采用新型摩擦材料，決定高壽命的(de)性能。

制(zhi)動(dong)器(qi)能在下列條件下可(ke)靠(kao)地工作:

1、周圍(wei)空氣相對濕度不大(da)于(yu)85%(20±5℃)

2、周圍介質中(zhong)，無足以腐蝕金屬和(he)破壞絕緣的氣體及塵埃。

3、制(zhi)動器(qi)周(zhou)圍采用B級絕緣(yuan)，電壓波動不超過+5%和-15%的額定電壓，其工(gong)作方式為連(lian)續工(gong)作制(zhi)

4、安裝時應保(bao)證傳動軸(zhou)部位與制動器的配合精度。

5、制動器(qi)的(de)制動盤必須在無油污的(de)情況下使用(yong)。

液(ye)壓制動器工作原理

制動(dong)(dong)器(qi)由(you)磁軛、勵磁線圈、彈簧、制動(dong)(dong)盤、銜鐵、花鍵套、安裝(zhuang)鏍釘等組成，制動(dong)(dong)器(qi)安裝(zhuang)在設(she)備的(de)法蘭(lan)盤(或電動(dong)(dong)機)的(de)后端伸;傳動(dong)(dong)軸(zhou)與(yu)花鍵套與(yu)制動(dong)(dong)盤聯結。

制(zhi)(zhi)(zhi)動(dong)(dong)(dong)器(qi)的勵磁(ci)線圈接(jie)通額定(ding)電(dian)(dian)(dian)壓(DC)時(shi)，電(dian)(dian)(dian)磁(ci)力吸合銜(xian)鐵(tie)，使銜(xian)鐵(tie)與制(zhi)(zhi)(zhi)動(dong)(dong)(dong)盤脫離(li)(li)(釋放(fang))，這時(shi)傳(chuan)動(dong)(dong)(dong)軸帶著制(zhi)(zhi)(zhi)動(dong)(dong)(dong)盤正常運轉或(huo)啟動(dong)(dong)(dong)，當傳(chuan)動(dong)(dong)(dong)系統(tong)分離(li)(li)或(huo)斷電(dian)(dian)(dian)時(shi)，制(zhi)(zhi)(zhi)動(dong)(dong)(dong)器(qi)也同時(shi)斷電(dian)(dian)(dian)，此時(shi)彈簧施壓于(yu)銜(xian)鐵(tie)，迫使制(zhi)(zhi)(zhi)動(dong)(dong)(dong)盤與銜(xian)鐵(tie)及法蘭盤之(zhi)間產生(sheng)摩(mo)擦力矩，使傳(chuan)動(dong)(dong)(dong)軸快速(su)停轉。在制(zhi)(zhi)(zhi)動(dong)(dong)(dong)器(qi)散熱環境較差，傳(chuan)動(dong)(dong)(dong)軸又是長時(shi)間連續(xu)工作(zuo)(zuo)時(shi)，如果條件允許，則可在制(zhi)(zhi)(zhi)動(dong)(dong)(dong)器(qi)工作(zuo)(zuo)后，保持電(dian)(dian)(dian)壓轉換為70%-80%的額定(ding)電(dian)(dian)(dian)壓，以減少發熱。
