Description
本發明係有關直線傳動元件，尤指一種螺帽旋轉式直線傳動元件。 The invention relates to a linear transmission element, in particular to a nut rotary linear transmission element.
按，螺帽旋轉式直線傳動元件(所述之傳動元件係為滾珠螺桿或滾柱螺桿)常使用於長行程之機台，先前多以驅動螺桿進而帶動螺帽位移，但因螺桿過長易有自重下垂及臨界轉速過低等問題，易衍生作動不順暢與產品壽命過短之問題；而動力源驅動傳動元件之螺帽旋轉，螺帽再帶動床台位移，故可避免動力源驅動傳動元件之螺桿時所產生的共振現象，而提高傳動元件的臨界轉速，以符合各種機台的需求，而螺帽旋轉式直線傳動元件顧名思義就是於原本傳動元件既有的螺帽上安裝軸承，而該軸承之外環係與機台固定，內環係固定於該螺帽，故動力源即可驅動該螺帽，使該螺帽旋轉而相對螺桿作直線往復運行，達到驅動床台的目的。 Press, the nut rotary linear transmission component (the transmission component is a ball screw or a roller screw) is often used in a long stroke machine. Previously, the screw was driven to drive the nut displacement, but the screw was too long. There are problems such as self-weight drooping and low critical speed, which is easy to derive the problem of unsmooth operation and short product life; while the power source drives the nut of the transmission component to rotate, and the nut drives the displacement of the bed, so the power source drive transmission can be avoided. The resonance phenomenon generated by the screw of the component improves the critical speed of the transmission component to meet the requirements of various machines, and the nut rotary linear transmission component, as the name suggests, is to mount the bearing on the existing nut of the original transmission component. The outer ring of the bearing is fixed to the machine table, and the inner ring is fixed to the nut. Therefore, the power source can drive the nut, and the nut rotates to perform linear reciprocating operation with respect to the screw to achieve the purpose of driving the bed.
誠如，我國公告第I254106號專利案，就為一種螺帽旋轉式傳動元件的形式之一，而該專利案主要欲解決的問題在於：螺帽旋轉式傳動元件的組裝問題。針對此問題，所提出的主要技術手段是於軸承套筒上設有填充滾珠的通孔，以方便填充滾珠至環狀珠槽中，然而，因為設置該通孔使得該環狀珠槽的軌道面產生一破損處，而必須使用一固定件來填補該破損處，但該固定 件往往無法使破損處填補的很平順，而產生斷差，而該斷差的產生會使得滾珠運行時不順暢(頓挫感)並且產生振動，故大幅降低了傳動元件的定位精度，且振動一產生久而久之磨耗也會越來越嚴重，故同時也縮短了傳動元件的使用壽命；再者，該固定件的設置也減少了傳動元件的負荷能力，原因在於：傳動元件的負荷能力高低取決於滾珠與軌道面接觸的多寡，故就算藉由該固定件來填補該破損處，而該填補後的破損處並不具有受負荷的能力，只有防止滾珠掉出環狀珠槽之能力，故多設置該通孔相對也降低了傳動元件的負荷能力；綜前述，此習知技術的設計仍有待改善之處。 For example, China Patent No. I254106 is one of the forms of a nut-rotating transmission component, and the main problem to be solved by the patent is the assembly problem of the nut rotary transmission component. In view of this problem, the main technical means proposed is to provide a through hole filled with balls on the bearing sleeve to facilitate filling the ball into the annular bead groove, however, because the through hole is provided to make the track of the annular bead groove The surface creates a break, and a fixture must be used to fill the break, but the fix The parts often fail to make the damage filled smoothly, and the gap is generated, and the generation of the break will make the ball run smoothly (frustration) and generate vibration, thus greatly reducing the positioning accuracy of the transmission element, and the vibration one The wear that lasts for a long time will become more and more serious, so the service life of the transmission component is also shortened. Moreover, the installation of the fixing component also reduces the load capacity of the transmission component, because the load capacity of the transmission component depends on the ball. The contact with the track surface, so that the damage is filled by the fixing member, and the damaged portion after the filling does not have the ability to be loaded, and only the ability to prevent the ball from falling out of the annular bead groove is provided. The through hole also relatively reduces the load capacity of the transmission element; in view of the foregoing, the design of this prior art still needs to be improved.

為求清楚說明本發明之實施特點，以下說明本發明較習用進步之處及實用方式：本發明螺帽旋轉式直線傳動元件之軸承套件的組配結構，主 要重點在於環套件(4)及螺帽(2)之環狀階級部(23)之設計，於組裝時，先將該螺帽(2)套設於該桿軸(1)，而後將第一滾動件(5)設置於該負荷路徑(90)，而後將該第二滾動件(9)使用潤滑脂黏置於外滾動溝(22)上，並佈滿整個外滾動溝(22)，再者，將該外套件(3)之通孔(31)套設於該螺帽(2)，使該第一內滾動溝(311)抵靠於該第二滾動件(9)，接著，將第二滾動件(9)使用潤滑脂黏置於該環套件(4)之外滾動槽(42)上【註：因潤滑脂為稠狀具有黏性，故可將第二滾動件(9)黏置於外滾動溝(22)或外滾動槽(42)，也因為該第二滾動件(9)可任意由任何方向排列於外滾動溝(22)或外滾動槽(42)，故針對靜音式傳動元件來說，須將第二滾動件(9)裝設於鏈條或排列於間隔子之間後，形成一滾動模組，即可將該滾動模組排列於開放式的外滾動溝(22)或外滾動槽(42)，故對於靜音式傳動元件來說裝配時就非常簡單方便，以縮短裝配時程，不像習知技術需從那麼小的通孔一一將滾珠及間隔子或滾珠及鏈條置入軌道中，故必須耗費相當時間才能夠完成裝配。】，再將該環套件(4)之貫穿孔(41)套設於該套設面(231)上，而該貫穿孔(41)與套設面(231)之間為緊密貼合之型態，才能讓該環套件(4)穩固的設置於該套設面(231)，並使該固定孔(43)相對該螺絲孔(24)設置，此時，該環套件(4)上之第二滾動件(9)係抵靠於第二內滾動溝(312)，最後，藉由複數該螺絲(6)穿設於該固定孔(43)後，各該螺絲(6)係與該螺絲孔(24)螺合鎖固；另外，藉由本發明的組配結構，亦可藉由螺絲(6)來調整第一負荷路徑(100)、第二負 荷路徑(101)與第二滾動件(9)之間的預壓力，前提該環套件(4)之端面(44)須與該環狀階級部(23)之端面(232)之間有間隙【註：本發明之第三圖所繪製的該環套件(4)之端面(44)與該環狀階級部(23)之端面(232)之間無間隙，是因為預壓力已調整了，故之間並無間隙產生，但假設該環套件(4)之端面(44)與該環狀階級部(23)之端面(232)調整完預壓力後仍有間隙，此種型態亦可實施但其剛性較差(此型態亦為本發明之實施範疇之一)，故無間隙的型態為最佳實施型態】，如此，藉由各該螺絲(6)的鎖固力，來達到調整該間隙之大小，如果該間隙越小，則表示該整第一負荷路徑(100)、第二負荷路徑(101)與第二滾動件(9)之間的預壓力越大，反之則預壓力越小，故藉由本發明之組配結構不但能保持完整的軌道面外，亦可達到調整預壓力的功能，以符合各種產業對於預壓力大小的要求。 In order to clearly illustrate the implementation features of the present invention, the following describes the advantages and practical aspects of the present invention: the assembly structure of the bearing set of the nut rotary linear transmission element of the present invention, The focus is on the design of the ring section (4) and the annular section (23) of the nut (2). When assembling, the nut (2) is first placed on the shaft (1), and then the first A rolling member (5) is disposed on the load path (90), and then the second rolling member (9) is adhered to the outer rolling groove (22) with grease, and the entire outer rolling groove (22) is covered. Furthermore, the through hole (31) of the outer sleeve (3) is sleeved on the nut (2) such that the first inner rolling groove (311) abuts against the second rolling member (9), and then The second rolling member (9) is adhered to the rolling groove (42) outside the ring set (4) by using grease [Note: Since the grease is thick and sticky, the second rolling member (9) can be used. Sticking to the outer rolling groove (22) or the outer rolling groove (42), also because the second rolling member (9) can be arbitrarily arranged in any direction in the outer rolling groove (22) or the outer rolling groove (42), For the silent transmission component, the second rolling element (9) must be installed on the chain or arranged between the spacers to form a rolling module, and the rolling module can be arranged in an open outer rolling. Ditch (22) or outer rolling groove (42), so for assembly of silent transmission components Very simple and convenient to shorten the assembly time course, unlike the conventional technology needs from eleven through holes as small balls or balls and spacer and into the track chain, it must be able to take a considerable time to complete the assembly. 】, the through hole (41) of the ring set (4) is sleeved on the sleeve surface (231), and the through hole (41) and the sleeve surface (231) are closely fitted together. The ring kit (4) is securely disposed on the sleeve surface (231), and the fixing hole (43) is disposed relative to the screw hole (24). At this time, the ring kit (4) is The second rolling member (9) is abutted against the second inner rolling groove (312). Finally, after the plurality of screws (6) are inserted through the fixing hole (43), the screws (6) are associated with the screw (6). The screw hole (24) is screwed and locked; in addition, the first load path (100) and the second negative can also be adjusted by the screw (6) by the assembly structure of the present invention. Preload between the load path (101) and the second rolling member (9), provided that there is a gap between the end face (44) of the ring set (4) and the end face (232) of the annular step portion (23) [Note: There is no gap between the end face (44) of the ring set (4) and the end face (232) of the annular step portion (23) drawn in the third drawing of the present invention because the pre-pressure has been adjusted. Therefore, there is no gap between them, but it is assumed that there is still a gap between the end face (44) of the ring set (4) and the end face (232) of the annular step portion (23) after adjusting the pre-pressure. However, the rigidity is poor (this type is also one of the implementation scopes of the present invention), so the type without gap is the best implementation type, and thus, by the locking force of each screw (6), Adjusting the size of the gap, if the gap is smaller, indicating that the pre-pressure between the entire first load path (100), the second load path (101) and the second rolling member (9) is larger, and vice versa. The smaller the pre-pressure, the more the track structure can be maintained by the assembly structure of the present invention, and the function of adjusting the pre-pressure can be achieved to meet the requirements of various industries for the pre-stress.
