本發明揭示一種油脂耦合器,其包括:一外套筒;一內套筒;一連接主體;一套環;一套環彈簧;夾爪,其等與一油脂嘴鎖定及解鎖;一噴嘴;一噴嘴彈簧;一套環滾珠溝槽;及一內滾珠溝槽;套筒鎖定滾珠;一噴嘴滾珠溝槽;及噴嘴鎖定滾珠。
Description
本發明係關於油脂耦合器。
油脂耦合器將一油脂嘴連接至來自一油脂槍之加壓油脂。
習知耦合器遭受若干缺點。尤其在高油脂壓力下,難以正向耦合及解耦耦合器與嘴。此需要大量體力且亦導致磨損,或甚至組件失效。缺乏正向耦合及解耦亦導致油脂洩露,或甚至導致高壓油脂噴回至一操作員。此外,耦合器內部之背壓的累積可導致防止耦合器與嘴之正向解耦之液壓鎖之形成。多數習知快釋耦合器係龐大的,此造成對緊密潤滑點之接取之問題。
在此內容背景中,需要改良式油脂耦合器。
根據本發明,提供一種油脂耦合器,其包括: 一外套筒,其可在一內套筒上軸向移動,其等之各者具有一入口端及一出口端; 一連接主體,其經連接至該內套筒之該入口端; 一套環,其可在該外套筒上該連接主體與該外套筒之該入口端之間軸向移動; 一套環彈簧,其在該內套筒之該入口端上該套環與該連接主體之間以將該套環朝向該外套筒之該出口端軸向偏置; 夾爪,其等可在該外套筒之該出口端中軸向及徑向移動以與一油脂嘴鎖定及解鎖; 一噴嘴,其可在該外套筒之該出口端中該等夾爪與該內套筒之該出口端之間軸向移動; 一噴嘴彈簧,其在該內套筒中該噴嘴與該連接主體之間; 該套環中之一套環滾珠溝槽及該內套筒中之一對應內滾珠溝槽; 套筒鎖定滾珠,其等可經由該外套筒中之滾珠孔在該套環滾珠溝槽與該內滾珠溝槽之間軸向及徑向移動; 一噴嘴滾珠溝槽,其在該噴嘴中;及 噴嘴鎖定滾珠,其等在該內套筒之該出口端中且可在由該噴嘴滾珠溝槽界定之一有限軸向距離內軸向移動; 其中軸向遠離該外套筒之該出口端之該套環之一第一回縮藉由將該等套筒鎖定滾珠從該套環滾珠溝槽軸向及徑向移動至該內滾珠溝槽以將該外套筒與該內套筒彼此鎖定以藉此容許該外套筒與該噴嘴之間的相對軸向移動以鎖定該等夾爪而預先裝備該油脂耦合器以耦合至該油脂嘴; 其中在該外套筒之該出口端內部推動該油脂嘴首先使該噴嘴軸向移動遠離該等夾爪以解鎖該等夾爪且壓縮該噴嘴彈簧,且隨後在該噴嘴彈簧之彈簧壓力下使該噴嘴朝向該油脂嘴軸向移動以藉此重新鎖定該等夾爪且將該噴嘴正向耦合至該油脂嘴;及 其中軸向遠離該外套筒之該出口端之該套環之一第二回縮將該等套筒鎖定滾珠從該內滾珠溝槽移動至該套環滾珠溝槽以將該外套筒及該內套筒彼此解鎖以藉此容許該外套筒與該噴嘴之間的相對軸向移動以藉此將該等夾爪與該油脂嘴解鎖,而該噴嘴與該內套筒之間的相對軸向移動藉由在由該噴嘴滾珠溝槽界定之有限軸向距離內之噴嘴鎖定滾珠之軸向移動限制,以藉此將該噴嘴與該油脂嘴正向解耦。
該外套筒之該出口端可具有一向內傾斜唇緣,其中該等夾爪可抵靠該向內傾斜唇緣軸向及徑向移動以與該油脂嘴鎖定及解鎖。
一噴嘴凸緣可自該噴嘴徑向延伸以使該等夾爪朝向該外套筒之該出口端處之該向內傾斜唇緣軸向移動。
一對把手可自該套環徑向延伸以軸向移動該套環軸向遠離該外套筒之該出口端。
一球形止回閥可設置於該連接主體中。
該球形止回閥可為一可調整滾珠止回閥。
本發明亦提供一種方法,其包括使用上文描述之油脂耦合器將一油脂嘴與來自一油脂槍之加壓油脂正向耦合及解耦。
參考圖1及圖2,根據本發明之一實施例之一油脂耦合器10可大體上包括一外套筒12、一致動套環14及一連接主體16。一對把手18可自套環14徑向延伸以軸向移動套環14軸向遠離外套筒12之一出口端。連接主體16可螺紋連接至一油脂槍軟管(未展示)。夾爪20可經設置於外套筒12之一出口端中以與一油脂嘴(例如,一Zerk嘴(未展示))鎖定及解鎖。把手18可為適當塑膠材料之一模製件,而剩餘組件可由適當金屬或金屬合金形成,除非另有陳述。
參考圖3,外套筒12可在一內套筒22上軸向移動。外套筒12及內套筒22可各具有一入口端及一出口端。連接主體16可經螺紋連接至內套筒22之入口端。套環14可在外套筒12上在連接主體16與外套筒12之入口端之間軸向移動。一套環彈簧24可經設置在內套筒22之入口端上套環14與連接主體16之間以使套環14朝向外套筒12之出口端軸向偏置。
夾爪20可在外套筒12之出口端中軸向及徑向移動以與一油脂嘴26鎖定及解鎖。外套筒12之出口端可具有一向內傾斜唇緣28,且夾爪20可抵靠向內傾斜唇緣28軸向及徑向移動以與油脂嘴26鎖定及解鎖。夾爪20可包括三個夾爪20,其等彼此以一浮動構形彼此周向隔開約120°以用於夾持油脂嘴26。此構形有利地提供最大夾持表面及油脂嘴26上之更低且更均勻接觸應力以避免損害油脂嘴26。與彼此周向隔開約90°之四個夾爪比較,夾爪20之三浮動構型更通用且更佳地符合油脂嘴26之標準化形狀、大小及公差(例如,SAE J534、BS1486及DIN71412可適用標準)。此係有利的,因為油脂嘴26由於成本之原因而不再加工,且因此油脂嘴26並非如過去般在尺寸上精確且一致。
一噴嘴30可在外套筒12之出口端中夾爪20與內套筒22之出口端之間軸向移動。連接主體16、內套筒22、外套筒12、噴嘴30可共用界定加壓油脂從油脂槍軟管至油脂嘴26之一流動通道。一噴嘴彈簧32可設置在內套筒22中噴嘴30與連接主體16之間。一橡膠噴嘴密封件34可設置於噴嘴30中。一噴嘴凸緣36可自噴嘴30徑向延伸以使夾爪20朝向外套筒12之出口端處之向內傾斜唇緣28軸向移動。
一套環滾珠溝槽38可形成在套環14中且一對應內滾珠溝槽40可形成在內套筒22中。套筒鎖定滾珠42可經由形成於外套筒12中之滾珠孔44而在套環滾珠溝槽38與內滾珠溝槽40之間軸向及徑向移動。
界定一有限軸向距離之一噴嘴滾珠溝槽46可形成在噴嘴30中。噴嘴鎖定滾珠48可經設置在內套筒22之出口端中且可在由噴嘴滾珠溝槽46界定之有限軸向距離內軸向移動。噴嘴鎖定滾珠48可藉由一扣環50及一卡環(或簧環(circlip)) 52軸向固持。一O形環54可經設置於噴嘴軸向內部之內套筒22上之一O形環溝槽。
一球形止回閥56可設置於連接主體16中。球形止回閥56可包括一閥彈簧58、一閥球60及一可調整閥座環62,可調整閥座環62在斷開之後提供來自油脂槍軟管之加壓油脂流之選擇性可調整限制。
參考圖4,軸向遠離外套筒12之出口端之套環14之一第一回縮藉由將套筒鎖定滾珠42從套環滾珠溝槽38軸向及徑向移動至內滾珠溝槽40以將外套筒12與內套筒22彼此鎖定以藉此容許外套筒12與噴嘴30之間的相對軸向移動以鎖定夾爪20而預先裝備油脂耦合器10以耦合至油脂嘴26。如在圖5中繪示,在第一回縮之後,藉由套環彈簧24使套環14朝向外套筒12之出口端往回軸向偏置。此使油脂套環10保持預先裝備且準備好正向耦合至油脂嘴26,如在圖6中繪示。
參考圖7,在外套筒12之出口端內部推動油脂嘴26首先使噴嘴30軸向移動遠離夾爪20以解鎖夾爪20且壓縮噴嘴彈簧32。如在圖8中繪示,噴嘴30隨後在噴嘴彈簧32之彈簧壓力下朝向油脂嘴26軸向移動以藉此重新鎖定夾爪20且將噴嘴30正向耦合至油脂嘴26。此使油脂耦合器10保持在與油脂嘴正向耦合之一狀態中,如在圖9中繪示,以容許將加壓油脂從油脂槍軟管供應至油脂嘴26。
參考圖10至圖13,軸向遠離外套筒12之出口端之套環14之一第二回縮使套筒鎖定滾珠42從內滾珠溝槽40移動回至套環滾珠溝槽38以將外套筒12及內套筒22彼此解鎖以藉此容許外套筒12與噴嘴30之間的相對軸向移動以將夾爪20與油脂嘴26解鎖,而噴嘴30與內套筒22之間的相對軸向移動藉由在由噴嘴滾珠溝槽46界定之有限軸向距離內軸向移動之噴嘴鎖定滾珠48限制,以將噴嘴30與油脂嘴26正向解耦。在解耦期間由噴嘴滾珠溝槽46及噴嘴鎖定滾珠48提供之正向噴嘴固持可克服來自油脂耦合器10內部之背壓之累積之油脂嘴26與噴嘴30之間的任何液壓鎖。
本發明之實施例提供可用於將油脂嘴與來自油脂槍之加壓油脂正向耦合及解耦同時避免或最小化油脂之洩露或回噴之油脂耦合器。
