橡膠(jiao)彈(dan)(dan)(dan)(dan)簧(huang)是一種高彈(dan)(dan)(dan)(dan)性(xing)(xing)(xing)體,制作材(cai)料有(you)(you)普(pu)通橡膠(jiao)。橡膠(jiao)彈(dan)(dan)(dan)(dan)簧(huang)彈(dan)(dan)(dan)(dan)性(xing)(xing)(xing)模量小(xiao),受(shou)載后有(you)(you)較大的彈(dan)(dan)(dan)(dan)性(xing)(xing)(xing)變形,借以吸收沖擊和(he)振(zhen)動。它能同時受(shou)多向(xiang)載荷,但耐(nai)(nai)高溫性(xing)(xing)(xing)和(he)耐(nai)(nai)油性(xing)(xing)(xing)比鋼彈(dan)(dan)(dan)(dan)簧(huang)差(cha)。如有(you)(you)特殊(shu)要求可用(yong)耐(nai)(nai)油橡膠(jiao)制成。該產品減(jian)振(zhen)效果好(hao),共振(zhen)領域小(xiao),使(shi)用(yong)壽命長,成本低(di),還有(you)(you)良好(hao)的耐(nai)(nai)寒性(xing)(xing)(xing),優良的氣密性(xing)(xing)(xing),防水性(xing)(xing)(xing),電絕緣性(xing)(xing)(xing),是減(jian)振(zhen)的最佳選擇。
橡(xiang)膠(jiao)彈簧是一種高(gao)彈性體,制(zhi)(zhi)作材料(liao)有普通橡膠。橡膠彈簧彈性(xing)模量(liang)小,受(shou)(shou)載(zai)后有較(jiao)大(da)的彈性(xing)變形(xing),借(jie)以吸收沖擊和振(zhen)動。它能(neng)同時(shi)受(shou)(shou)多向載(zai)荷,但耐(nai)(nai)高溫性(xing)和耐(nai)(nai)油性(xing)比鋼彈簧差。如有特殊要(yao)求可用耐(nai)(nai)油橡膠制(zhi)(zhi)成。該產(chan)品減振(zhen)效果(guo)好(hao),共(gong)振領域小,使(shi)用壽命長,成本(ben)低,還有良好的耐寒性,優良的氣密性,防水性,電絕(jue)緣性(xing),是減振的(de)最(zui)佳(jia)選擇。
橡(xiang)膠(jiao)彈(dan)簧(huang)(huang)(huang)形(xing)狀不受限(xian)制(zhi),有較大的彈(dan)性(xing)變(bian)形(xing),容易實現非線(xian)(xian)性(xing)要求(qiu),減(jian)振隔音(yin)效果良好。復合(he)橡(xiang)膠(jiao)彈(dan)簧(huang)(huang)(huang)相比(bi)較橡(xiang)膠(jiao)彈(dan)簧(huang)(huang)(huang),前(qian)者(zhe)形(xing)狀受金(jin)屬螺旋彈(dan)簧(huang)(huang)(huang)限(xian)制(zhi),線(xian)(xian)性(xing)要求(qiu)高,重量(liang)重,但是(shi)其承(cheng)重載荷量(liang)大的優點卻不是(shi)純(chun)橡(xiang)膠(jiao)彈(dan)簧(huang)(huang)(huang)可比(bi)擬的。
優點(dian) (1)形(xing)狀不(bu)受(shou)限制(zhi),各個(ge)方向的剛度可以根據設計要(yao)求自由選擇; (2)彈(dan)性(xing)模量雖小,可以得到較大的彈(dan)性(xing)變(bian)形,容易(yi)實現(xian)理想的非線性(xing)特性(xing); (3)具有較高的內阻.這對于突然(ran)沖擊和高頻振動的吸(xi)收以及隔(ge)音具有良好(hao)的效果; (4)同一橡膠彈簧能同時承受(shou)多向載荷,從而使(shi)系(xi)統的結構簡(jian)化; (5)安裝和拆卸簡便,無需(xu)潤滑,有利于維護保養.
缺點(dian) (1)耐(nai)高低溫和耐(nai)油性比鋼彈簧(huang)差; (2)工程中用橡膠彈簧,形(xing)狀(zhuang)比波(bo)紋管簡單,但要(yao)精確計(ji)算它們的彈性特性卻相當困難;
