彈(dan)性(xing)(xing)聯軸(zhou)器作(zuo)為機械傳(chuan)動系統中連(lian)接兩軸(zhou)、傳(chuan)遞扭矩的常(chang)用(yong)(yong)部件，憑借其對(dui)安裝偏差的補(bu)償能(neng)力和(he)緩(huan)沖減(jian)振效果，在(zai)各類通用(yong)(yong)機械中應(ying)用(yong)(yong)廣(guang)泛。但受結構設計、材料特性(xing)(xing)及工作(zuo)原(yuan)理限制(zhi)，其自(zi)身存在(zai)諸多固有缺點，這些不足在(zai)特定(ding)工況下(xia)會顯著影(ying)響傳(chuan)動系統的穩定(ding)性(xing)(xing)、精度和(he)使用(yong)(yong)壽命，需在(zai)選型和(he)使用(yong)(yong)中考量(liang)。

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。彈性聯軸器運用平行(xing)或螺旋切槽系(xi)統來適應各(ge)種偏差(cha)和精確傳遞扭(niu)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.

傳動效率存在天然損耗是彈性聯軸器的核心缺點之一。與剛性聯軸器直接傳遞扭矩的方式不同，彈性聯軸器需(xu)通過橡(xiang)膠(jiao)、聚(ju)氨酯、金屬膜(mo)片或(huo)彈簧等彈性元件傳(chuan)(chuan)遞動(dong)力，而(er)這(zhe)些(xie)元件在(zai)(zai)受(shou)力過程中(zhong)(zhong)(zhong)必然產(chan)生微小形變，部分能(neng)量會轉化為形變能(neng)或(huo)熱(re)能(neng)消耗(hao)，導(dao)致(zhi)傳(chuan)(chuan)動(dong)效(xiao)率低(di)于剛性聯軸(zhou)器(qi)。這(zhe)種(zhong)能(neng)量損(sun)(sun)耗(hao)在(zai)(zai)低(di)速(su)輕載(zai)工況下表現(xian)不明(ming)顯(xian)，但在(zai)(zai)高速(su)重(zhong)載(zai)場(chang)景中(zhong)(zhong)(zhong)會被(bei)放大(da)，不僅降(jiang)低(di)整體傳(chuan)(chuan)動(dong)效(xiao)率，還可能(neng)因彈性元件持續形變發熱(re)加速(su)老(lao)化，形成惡性循(xun)環。尤其在(zai)(zai)對能(neng)量利(li)用率要求(qiu)較高的設備中(zhong)(zhong)(zhong)，這(zhe)種(zhong)效(xiao)率損(sun)(sun)耗(hao)需(xu)通過增大(da)聯軸(zhou)器(qi)規格(ge)或(huo)優(you)化傳(chuan)(chuan)動(dong)結(jie)構彌補，間接增加了設備整體成本。

彈(dan)(dan)性(xing)(xing)元件易老化(hua)磨損，導致維護(hu)成本上升且影響(xiang)設備連續性(xing)(xing)運行，是(shi)彈(dan)(dan)性(xing)(xing)聯(lian)軸(zhou)(zhou)器突出(chu)(chu)(chu)的短板。多數彈(dan)(dan)性(xing)(xing)聯(lian)軸(zhou)(zhou)器采用(yong)非金(jin)(jin)屬彈(dan)(dan)性(xing)(xing)元件，這類材(cai)料(liao)受(shou)溫(wen)度、濕度、油脂及環境(jing)介(jie)質影響(xiang)極大，長期(qi)(qi)使(shi)用(yong)后會出(chu)(chu)(chu)現硬化(hua)、龜裂、變形等老化(hua)現象(xiang)，使(shi)用(yong)壽命有限。在(zai)正常工況下，非金(jin)(jin)屬彈(dan)(dan)性(xing)(xing)元件通常需定期(qi)(qi)更(geng)換，更(geng)換周期(qi)(qi)受(shou)環境(jing)條件制約(yue)，高溫(wen)、潮濕或存在(zai)腐蝕性(xing)(xing)介(jie)質的場景中，更(geng)換頻率會明顯增加，不僅耗費人力(li)物力(li)，還(huan)會因停機維護(hu)影響(xiang)生產進度。即(ji)使(shi)是(shi)金(jin)(jin)屬彈(dan)(dan)性(xing)(xing)元件，在(zai)長期(qi)(qi)承受(shou)交變載荷和角度偏(pian)差補(bu)償時，也(ye)會出(chu)(chu)(chu)現疲勞(lao)磨損，尤其當軸(zhou)(zhou)系偏(pian)差超過設計(ji)范圍時，磨損速度會急劇加快，需頻繁檢查維護(hu)才能避免(mian)突發失效(xiao)。

傳(chuan)(chuan)動(dong)(dong)精(jing)度(du)不足(zu)，難以(yi)滿足(zu)高精(jing)度(du)傳(chuan)(chuan)動(dong)(dong)需求(qiu)，是(shi)彈(dan)性聯(lian)(lian)(lian)(lian)軸(zhou)器(qi)(qi)在(zai)精(jing)密設(she)備中應用(yong)受限的(de)主要(yao)原因。彈(dan)性元(yuan)件的(de)形變特性雖能補(bu)償安裝偏差，但同時會帶來微(wei)量的(de)傳(chuan)(chuan)動(dong)(dong)滯后和彈(dan)性回差，這(zhe)種偏差在(zai)正反轉(zhuan)頻繁的(de)工況下(xia)會被累積放(fang)大(da)，影(ying)響傳(chuan)(chuan)動(dong)(dong)系統(tong)的(de)定位精(jing)度(du)和響應速度(du)。對于精(jing)密機床、伺服傳(chuan)(chuan)動(dong)(dong)等對傳(chuan)(chuan)動(dong)(dong)精(jing)度(du)要(yao)求(qiu)嚴苛的(de)設(she)備，這(zhe)種微(wei)小(xiao)偏差會直接(jie)影(ying)響加工精(jing)度(du)或控制(zhi)效果，因此(ci)這(zhe)類(lei)場景通常需選用(yong)特殊(shu)結(jie)構的(de)聯(lian)(lian)(lian)(lian)軸(zhou)器(qi)(qi)，而非普通彈(dan)性聯(lian)(lian)(lian)(lian)軸(zhou)器(qi)(qi)。不同類(lei)型(xing)的(de)彈(dan)性聯(lian)(lian)(lian)(lian)軸(zhou)器(qi)(qi)精(jing)度(du)差異(yi)較大(da)，即使是(shi)金(jin)屬膜片式彈(dan)性聯(lian)(lian)(lian)(lian)軸(zhou)器(qi)(qi)，其精(jing)度(du)也(ye)無法完全媲美剛性聯(lian)(lian)(lian)(lian)軸(zhou)器(qi)(qi)，在(zai)超精(jing)密傳(chuan)(chuan)動(dong)(dong)領(ling)域難以(yi)適用(yong)。

扭矩傳(chuan)遞能(neng)力(li)有限，對重載工況適應(ying)性較差(cha)。受(shou)彈(dan)性元(yuan)(yuan)件強度和結構設(she)計限制(zhi)，相(xiang)同尺寸規格下，彈(dan)性聯(lian)(lian)軸器(qi)(qi)(qi)(qi)的(de)(de)額定(ding)扭矩低(di)于剛性聯(lian)(lian)軸器(qi)(qi)(qi)(qi)。非金屬(shu)彈(dan)性元(yuan)(yuan)件的(de)(de)承載能(neng)力(li)受(shou)材料(liao)強度制(zhi)約，超(chao)過額定(ding)扭矩易發生(sheng)斷(duan)裂或變形；金屬(shu)彈(dan)性元(yuan)(yuan)件雖承載能(neng)力(li)更(geng)強，但相(xiang)比(bi)同尺寸剛性聯(lian)(lian)軸器(qi)(qi)(qi)(qi)仍有差(cha)距，重載場景下需選(xuan)用更(geng)大(da)規格的(de)(de)產品，這會(hui)導致聯(lian)(lian)軸器(qi)(qi)(qi)(qi)徑向(xiang)和軸向(xiang)占用空間增加，與(yu)設(she)備緊(jin)湊化設(she)計需求產生(sheng)矛盾。部分重載設(she)備為兼顧(gu)緩(huan)沖需求選(xuan)用彈(dan)性聯(lian)(lian)軸器(qi)(qi)(qi)(qi)后，需預留更(geng)大(da)的(de)(de)扭矩安(an)全余量，不(bu)僅(jin)增加了選(xuan)型成本，還可能(neng)因結構尺寸過大(da)影(ying)響周邊(bian)部件布局。

工(gong)作(zuo)環(huan)境(jing)適(shi)應性(xing)(xing)(xing)較弱(ruo)，易受溫(wen)(wen)度、介(jie)(jie)質等因素制約。非金屬(shu)(shu)彈(dan)性(xing)(xing)(xing)元(yuan)(yuan)件(jian)(jian)對工(gong)作(zuo)溫(wen)(wen)度范圍有嚴(yan)格(ge)要求，過(guo)(guo)高溫(wen)(wen)度會導致(zhi)材(cai)料(liao)軟化(hua)失效(xiao)，過(guo)(guo)低溫(wen)(wen)度則會使(shi)(shi)材(cai)料(liao)脆化(hua)開裂(lie)，普通橡膠彈(dan)性(xing)(xing)(xing)元(yuan)(yuan)件(jian)(jian)的適(shi)用溫(wen)(wen)度范圍較窄(zhai)，即使(shi)(shi)是聚(ju)氨酯材(cai)料(liao)，在(zai)極端溫(wen)(wen)度環(huan)境(jing)下性(xing)(xing)(xing)能(neng)也會大幅下降。在(zai)存在(zai)油(you)污、酸(suan)堿等腐蝕性(xing)(xing)(xing)介(jie)(jie)質的場景(jing)中(zhong)，非金屬(shu)(shu)彈(dan)性(xing)(xing)(xing)元(yuan)(yuan)件(jian)(jian)易被腐蝕，表面(mian)出現(xian)溶脹、龜(gui)裂(lie)，喪失彈(dan)性(xing)(xing)(xing)功能(neng)；金屬(shu)(shu)彈(dan)性(xing)(xing)(xing)元(yuan)(yuan)件(jian)(jian)雖耐(nai)腐蝕性(xing)(xing)(xing)能(neng)較好，但(dan)長期接(jie)觸腐蝕性(xing)(xing)(xing)介(jie)(jie)質仍會發(fa)生銹蝕，削弱(ruo)結構強(qiang)度。此外，在(zai)多(duo)粉塵(chen)環(huan)境(jing)中(zhong)，粉塵(chen)易進入(ru)彈(dan)性(xing)(xing)(xing)元(yuan)(yuan)件(jian)(jian)與金屬(shu)(shu)部(bu)件(jian)(jian)的間(jian)隙(xi)，加劇磨損(sun)，同(tong)時影(ying)響彈(dan)性(xing)(xing)(xing)變形的靈活(huo)性(xing)(xing)(xing)，進一步縮短使(shi)(shi)用壽命(ming)。

結構(gou)剛(gang)性(xing)(xing)不(bu)足(zu)，易(yi)引發軸(zhou)系振(zhen)動(dong)(dong)(dong)和共振(zhen)風險。彈性(xing)(xing)聯(lian)(lian)軸(zhou)器的(de)(de)(de)彈性(xing)(xing)元件(jian)會降低整個傳動(dong)(dong)(dong)系統的(de)(de)(de)剛(gang)性(xing)(xing)，在(zai)高(gao)速運行(xing)時，若(ruo)系統固有頻(pin)(pin)率與設備(bei)運行(xing)頻(pin)(pin)率接(jie)近，易(yi)產(chan)生共振(zhen)現象，導(dao)致軸(zhou)系振(zhen)動(dong)(dong)(dong)加劇(ju)，不(bu)僅影(ying)響傳動(dong)(dong)(dong)穩定性(xing)(xing)，還可能對電機、軸(zhou)承等關聯(lian)(lian)部(bu)件(jian)造(zao)成額(e)外沖擊。部(bu)分類型的(de)(de)(de)彈性(xing)(xing)聯(lian)(lian)軸(zhou)器徑向尺寸較(jiao)大，高(gao)速旋轉時產(chan)生的(de)(de)(de)離心力較(jiao)大，若(ruo)動(dong)(dong)(dong)平衡精(jing)度不(bu)足(zu)，會進(jin)一步放大振(zhen)動(dong)(dong)(dong)，甚至引發部(bu)件(jian)松動(dong)(dong)(dong)。這種振(zhen)動(dong)(dong)(dong)問題在(zai)高(gao)速精(jing)密設備(bei)中更為突出，需通(tong)過額(e)外的(de)(de)(de)減振(zhen)措(cuo)施或(huo)平衡校正彌補(bu)，增加了設備(bei)調(diao)試(shi)和運行(xing)難(nan)度。

部(bu)(bu)(bu)分類型彈(dan)(dan)性聯軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)存在(zai)安(an)裝維(wei)護(hu)復雜度較(jiao)高(gao)的(de)問題。金(jin)屬膜片(pian)式彈(dan)(dan)性聯軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)雖(sui)壽命較(jiao)長(chang)(chang)，但對安(an)裝精度要求較(jiao)高(gao)，兩軸(zhou)(zhou)(zhou)(zhou)(zhou)對中偏差超過允許范圍會顯著縮短膜片(pian)壽命，安(an)裝時需(xu)借助專(zhuan)業工具校準(zhun)，對操作人員技(ji)能(neng)要求較(jiao)高(gao)。齒式彈(dan)(dan)性聯軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)需(xu)定期加注潤滑(hua)劑(ji)，若潤滑(hua)不及時或(huo)(huo)潤滑(hua)方式不當，會導致齒面磨(mo)損加劇、發熱嚴重，影響傳動性能(neng)；蛇形(xing)彈(dan)(dan)簧式彈(dan)(dan)性聯軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)的(de)彈(dan)(dan)簧易磨(mo)損，且更(geng)換(huan)時需(xu)拆(chai)卸周邊(bian)部(bu)(bu)(bu)件(jian)，操作繁(fan)瑣。此外，部(bu)(bu)(bu)分彈(dan)(dan)性聯軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)的(de)彈(dan)(dan)性元(yuan)件(jian)與金(jin)屬部(bu)(bu)(bu)件(jian)連接緊密，長(chang)(chang)期使(shi)用后可能(neng)出(chu)現(xian)粘連或(huo)(huo)卡(ka)滯，增(zeng)加拆(chai)卸難度，延(yan)長(chang)(chang)維(wei)護(hu)時間(jian)。

彈(dan)性(xing)聯軸器(qi)的(de)缺點(dian)多源于其彈(dan)性(xing)傳(chuan)動(dong)的(de)核心原理和材料(liao)特性(xing)，這(zhe)些不(bu)足在(zai)(zai)不(bu)同(tong)(tong)工況(kuang)下的(de)影響(xiang)(xiang)程度存在(zai)(zai)差異。在(zai)(zai)實際應用中(zhong)，需(xu)結合傳(chuan)動(dong)精(jing)度要求、載荷大(da)小、工作環境(jing)及維(wei)護條件綜合考量，通過合理選型、優化安(an)裝和加(jia)強維(wei)護等方式規避(bi)缺點(dian)帶來(lai)的(de)負面影響(xiang)(xiang)。同(tong)(tong)時，針對不(bu)同(tong)(tong)場景(jing)的(de)需(xu)求，需(xu)在(zai)(zai)緩沖減(jian)振、傳(chuan)動(dong)精(jing)度、承載能力和維(wei)護便(bian)捷性(xing)之間尋找(zhao)平衡，避(bi)免(mian)因單一需(xu)求忽視缺點(dian)帶來(lai)的(de)潛(qian)在(zai)(zai)風險(xian)，確(que)保(bao)傳(chuan)動(dong)系統長期(qi)穩定運行。
