彈性聯軸器是一體成型的金屬彈性體，通常由金屬圓棒線切割而成，常用的材質有鋁合金、不銹鋼、工程塑料，適合于各種偏差和精確傳遞扭矩。彈性聯軸器含有預壓橡膠的彈性化合物，可提供額外強度，延長使用壽命。輪轂材質為高強度鋁合金，既輕巧又防腐蝕。 其中橡膠成分主要用于減震，使動力傳輸流暢、安靜，從而保護驅動力以及驅動機器。彈性聯軸器運用平(ping)行或螺(luo)旋切槽系統(tong)來(lai)適應各種偏差和(he)精確(que)傳遞扭矩。

Elastic coupling is a metal elastic body that is integrally formed, usually cut from metal round bars. Commonly used materials include aluminum alloy, stainless steel, and engineering plastics, which are suitable for various deviations and precise torque transmission. The elastic coupling contains an elastic compound of pre pressed rubber, which can provide additional strength and extend its service life. The wheel hub material is high-strength aluminum alloy, which is both lightweight and corrosion-resistant. The rubber component is mainly used for shock absorption, making power transmission smooth and quiet, thereby protecting the driving force and driving machines. Flexible Couplings use parallel or spiral groove systems to adapt to various deviations and accurately transmit torque.

彈性聯軸器的核心結構由兩半聯軸器、彈性(xing)元(yuan)(yuan)件(jian)(jian)(jian)及連(lian)(lian)接(jie)部(bu)(bu)件(jian)(jian)(jian)構成，各部(bu)(bu)分(fen)協同作(zuo)用支撐其機械功能(neng)的實現。兩半聯軸器分(fen)別與(yu)(yu)主動(dong)軸、從動(dong)軸連(lian)(lian)接(jie)，通常采(cai)用高強度合金(jin)(jin)(jin)鋼或鋁合金(jin)(jin)(jin)加工制(zhi)成，通過(guo)過(guo)盈配合、螺栓連(lian)(lian)接(jie)或鍵(jian)槽固定(ding)等(deng)方式與(yu)(yu)軸緊密銜接(jie)，確(que)保扭矩傳遞時(shi)不(bu)發生相對滑(hua)動(dong)，保障傳動(dong)效率(lv)。彈性(xing)元(yuan)(yuan)件(jian)(jian)(jian)作(zuo)為核心功能(neng)部(bu)(bu)件(jian)(jian)(jian)，材(cai)質(zhi)可分(fen)為非(fei)金(jin)(jin)(jin)屬(shu)與(yu)(yu)金(jin)(jin)(jin)屬(shu)兩類，非(fei)金(jin)(jin)(jin)屬(shu)元(yuan)(yuan)件(jian)(jian)(jian)多采(cai)用橡膠(jiao)、聚(ju)氨(an)酯(zhi)等(deng)柔性(xing)材(cai)料，金(jin)(jin)(jin)屬(shu)元(yuan)(yuan)件(jian)(jian)(jian)則以不(bu)銹(xiu)鋼薄(bo)片(pian)、蛇形彈簧為主，不(bu)同材(cai)質(zhi)的彈性(xing)元(yuan)(yuan)件(jian)(jian)(jian)決(jue)定(ding)了聯軸器的承(cheng)載能(neng)力、補償(chang)范圍與(yu)(yu)使用壽命(ming)。連(lian)(lian)接(jie)部(bu)(bu)件(jian)(jian)(jian)主要用于固定(ding)彈性(xing)元(yuan)(yuan)件(jian)(jian)(jian)與(yu)(yu)兩半聯軸器，結(jie)構設計需(xu)匹配彈性(xing)元(yuan)(yuan)件(jian)(jian)(jian)的形變特性(xing)，避免(mian)限制(zhi)其緩沖與(yu)(yu)補償(chang)功能(neng)的發揮。

扭矩傳遞是彈性聯軸器基礎的機械功能，其原理基于彈性元件的彈性形變與力的傳遞特性。當主動軸在動力驅動下旋轉時，會通過與主動軸連接的半聯軸器將扭矩傳遞至彈性元件，使彈性元件發生微小彈性形變，這種形變會產生反向彈力，將扭矩進一步傳遞至從動端的半聯軸器，帶動從動軸同步旋轉，完成動力傳輸。與剛性傳動不同，彈性聯軸器的扭矩傳遞存在輕微的彈性滯后，這是由于彈性元件形變過程中存在少量能量損耗，這種損耗雖會使傳動效率略低于剛性聯軸器，但能有效緩(huan)沖主動軸的(de)瞬時(shi)沖擊(ji)，避免扭矩突變對(dui)從動軸及后續(xu)設備(bei)造成損壞。不同類型的(de)彈性聯軸器(qi)扭矩傳遞能力差異較大，主要取(qu)決于彈性元件的(de)材(cai)質強度、結構尺(chi)寸及受力方式，可根據工(gong)況負載需求選擇適配類型。

偏差補(bu)償(chang)是彈(dan)(dan)性(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)區(qu)別于剛性(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)的關鍵功能(neng)，其原理同樣依賴彈(dan)(dan)性(xing)元件的可形(xing)變(bian)特性(xing)。工(gong)業設備(bei)安(an)裝(zhuang)(zhuang)過(guo)程中(zhong)，受加工(gong)精(jing)度、安(an)裝(zhuang)(zhuang)工(gong)藝、設備(bei)運行(xing)中(zhong)的基礎沉降等(deng)(deng)因素影響，主動(dong)軸(zhou)(zhou)與(yu)(yu)從動(dong)軸(zhou)(zhou)之間易出(chu)現同軸(zhou)(zhou)度偏差、角(jiao)(jiao)向(xiang)(xiang)(xiang)偏差及軸(zhou)(zhou)向(xiang)(xiang)(xiang)位移，若無法有效(xiao)補(bu)償(chang)，會(hui)(hui)導致(zhi)軸(zhou)(zhou)系振動(dong)加劇、軸(zhou)(zhou)承(cheng)發熱，甚至造(zao)成(cheng)軸(zhou)(zhou)體斷裂(lie)等(deng)(deng)故(gu)障。彈(dan)(dan)性(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)的彈(dan)(dan)性(xing)元件可通過(guo)自身(shen)形(xing)變(bian)吸收(shou)這些偏差，當(dang)兩(liang)軸(zhou)(zhou)存在徑(jing)(jing)向(xiang)(xiang)(xiang)偏移時(shi)，彈(dan)(dan)性(xing)元件會(hui)(hui)發生(sheng)徑(jing)(jing)向(xiang)(xiang)(xiang)拉伸或壓縮形(xing)變(bian)；當(dang)存在角(jiao)(jiao)向(xiang)(xiang)(xiang)偏差時(shi)，會(hui)(hui)產生(sheng)剪切形(xing)變(bian)；當(dang)出(chu)現軸(zhou)(zhou)向(xiang)(xiang)(xiang)位移時(shi)，則會(hui)(hui)通過(guo)伸縮形(xing)變(bian)適配，從而減少軸(zhou)(zhou)系之間的相(xiang)互作用力(li)(li)，降低安(an)裝(zhuang)(zhuang)精(jing)度要求，保障傳動(dong)系統穩定運行(xing)。不同結(jie)構的彈(dan)(dan)性(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)補(bu)償(chang)能(neng)力(li)(li)不同，例如(ru)梅(mei)花形(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)側(ce)重(zhong)徑(jing)(jing)向(xiang)(xiang)(xiang)與(yu)(yu)角(jiao)(jiao)向(xiang)(xiang)(xiang)偏差補(bu)償(chang)，金(jin)屬膜(mo)片式聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)則能(neng)兼(jian)顧高精(jing)度補(bu)償(chang)與(yu)(yu)剛性(xing)傳動(dong)需求。

緩沖(chong)減振(zhen)(zhen)與(yu)過載(zai)保護是彈性(xing)(xing)(xing)聯(lian)軸器的(de)(de)(de)重要(yao)附加功(gong)能(neng)，其(qi)機械原理與(yu)彈性(xing)(xing)(xing)元件的(de)(de)(de)形(xing)變極限(xian)及能(neng)量吸收能(neng)力密(mi)切相關。工業設(she)(she)備(bei)運行時(shi)(shi)，電(dian)機啟動(dong)、負載(zai)波動(dong)等(deng)情況會(hui)產(chan)生瞬(shun)時(shi)(shi)沖(chong)擊(ji)振(zhen)(zhen)動(dong)，這些振(zhen)(zhen)動(dong)若(ruo)直接傳遞至整個傳動(dong)系統(tong)，會(hui)影響設(she)(she)備(bei)運行精度(du)(du)，縮短(duan)零部(bu)件使用(yong)(yong)壽命(ming)。彈性(xing)(xing)(xing)元件在承受沖(chong)擊(ji)時(shi)(shi)，會(hui)通(tong)過形(xing)變吸收部(bu)分沖(chong)擊(ji)能(neng)量，將瞬(shun)時(shi)(shi)沖(chong)擊(ji)力轉化為彈性(xing)(xing)(xing)勢能(neng)，再逐(zhu)步(bu)釋(shi)放，從(cong)而削弱(ruo)振(zhen)(zhen)動(dong)幅度(du)(du)，降低運行噪音(yin)，尤其(qi)適用(yong)(yong)于精密(mi)機床、伺服系統(tong)等(deng)對振(zhen)(zhen)動(dong)敏感的(de)(de)(de)設(she)(she)備(bei)。同時(shi)(shi)，彈性(xing)(xing)(xing)元件存在一定的(de)(de)(de)形(xing)變極限(xian)，當(dang)負載(zai)超過額定扭矩(ju)(ju)時(shi)(shi)，彈性(xing)(xing)(xing)元件會(hui)發(fa)生過度(du)(du)形(xing)變甚至斷裂，切斷扭矩(ju)(ju)傳遞，避免電(dian)機、軸系等(deng)核心部(bu)件因(yin)過載(zai)而燒毀，起到被動(dong)過載(zai)保護的(de)(de)(de)作(zuo)用(yong)(yong)。
