改善。 X 目則的;袞珠螺桿料為了改善，高轉速、高負荷情形 下產生的摩擦高溫，皆會在螺桿與螺帽裝設冷卻裝置，進 而降低滾珠螺桿溫度；然而，不同料都有其缺陷存在， 所以’如何針對冷卻裝置研發改良出更具競爭 然成為目前業界之重點。自 1300375 現今較為習知的冷卻裝置，如日本專利特開昭 63-1956，其係於螺帽周緣設置冷卻循環路徑，且螺帽座 上也設置相互連通的冷卻路徑，使兩者的冷卻路徑構成冷 卻循環路徑，這樣的冷卻循環路徑相當的繁瑣，且必須於 螺帽座上加工冷卻循環道，相對提高其加工難度與成本， 且其冷卻液對流效果不佳，故冷卻較不均勻，而直接影響 到冷卻的效果。 另如日本專利特開平11-333666則係於螺帽前後端 加裝冷卻裝置，該冷卻裝置是一種利用空氣對流產生擾 流，而達到冷卻之目的，但於螺帽兩端採空氣對流的方 法，其能帶走的熱源有效，直接影響到其冷卻效果，且其 無法深入螺帽内部，容易造成冷卻不均勻的現象，有進一 步改善之必要。 再者如日本專利特許3721264號者，其係在螺桿軸、 螺帽及馬達座上均設有冷卻通道，並設計成循環之冷卻迴 路，透過冷卻液溫度調節裝置做為冷熱交換，而達到冷卻 的效果，但由於係採冷卻液來降溫，一旦密封結構失效， 將導致冷卻液外溢的現象，而造成環境污染的問題。 而前述專利前案的共同問題在於：由於其無法有效的 接近熱源，再加上其冷卻液的流動速度完全由冷卻裝置的 輸出力來決定，故其流動速度較慢，且僅有冷卻液外周緣 處可供吸熱，因此其整體的冷卻效果不彰，散熱速度也 慢，再者部份現有設計的結構較為複雜，同時製造不良， 1300375 而造成組配的不便，無形間 施a夕相女从 巧其加工製造的成本。 換&之’現有的螺帽的、人，、 ^ 々部結構因:&冷卻液的流動速 度慢，且僅有外緣部份能钱和w縣自1抓料 旲，ra 处你vw、 …、’而影響到其降溫速度與效 果，因此如能使冷卻液的速 此，目從加快，且令冷卻液呈擾流 狀則可增加其吸熱面積與竦洚 对吳，而*八姐如m 、度，進一步即可提升其冷卻 效果，而本發明即用於達成此一 一目的。 【發明内容】 基於上述習知滾珠螺桿冷肤 過研究改良後，終有確能達、置之缺點，本發明人經 生。 建成以下發明目的之本發明誕 即本么明之主要目的在於，使冷卻液受擾流元件之 螺旋葉片的作用，而產生螺旋狀的流動前進，能強制擾流 使冷卻液充份吸收熱源，有效將滾珠螺桿__，以提 升冷卻效果，進而提升滾珠螺桿之壽命與積度。 本發明之次要目的在於，提供—種結構簡化之螺帽螺 旋冷卻裝置’其能易於製造、且便於組裝，而能節省成本。 、為達上述之發明目的，本發明係利用設有螺旋秦片之 擾流7〇件’裝設於螺桿與螺帽冷卻流道中，其擾流元件 勺使々部液又擾流元件螺旋流道的作用， 狀的流動前進，目ή 1 # 座生螺方疋 則Ύ增加其吸熱面積充分的帶 一步即可提升龙 走熱源，進 a 升，、冷郃效果；另外值得一提 造魴單，不需複蕷 夂々钾裝置構 及雜之配件搭配，主要利用 叫累知與螺帽所剩 1300375 空間，以不影響螺桿與螺帽之強度為原則，來加工冷卻济 道；其上述擾流元件材質為撓性材質，開模時可旋轉脫 极’易於製造量產，且在—定規格内的冷卻流道時可共 用，具有相當的通用性，故本發明不但改善習知冷卻裝置 之缺點、且又添加了高通用性與易於製造 接下來舉-較佳實施例，並配合圖式及圖號十對本 發明做進-步之說明，期缺貴審查委㈣本發明有更 評細的瞭解’惟以下所述者僅為絲解釋本發明之較佳實 施例’並非企圖據以對本發明做任何形式上之限制，是 以’凡疋在本發明之創作精神下，而為本發明任何型式的 修飾或變更，皆仍應屬於本發明意圖保護之範脅。 【實施方式】 本發明第一實施例請參閱第一圖至第四圖所示，本發 明第-實施例’係於螺桿（5)中心部位加工一貫穿轴向 流道（5 1 )，如圖二所示，該軸向流道（5 i )與螺桿 螺紋溝槽（5 2 )之轉可料最接近之距離，但要以不 影響螺桿（5 )之鋼性為考量，如圖四所示，以利於冷卻 液充分吸收熱源；再者，於軸向流道（5丄）内安裝一擾 流70件（8 0 )其擾流元件（8 〇 )上設有螺旋葉片（8 0 1 )’其擾流元件（8 〇 )係由撓性材質製成，如圖一 所不，於加工軸向流道（51 )不需刻意要求其裝配公差； 1300375 且t裝擾元件（8 0 )後的轴向流道（5 1 )，内部係 , 形成一螺旋狀流道，其螺旋狀流道主要目的能擾動冷卻 液，讓冷卻液可充分吸收熱源，並使其流動更為順暢； 以上所述，即為本發明第一實施例各相關元件的相互 關係位置及其概述。 本發明第二實施例請參閱第一圖、第五圖及第四圖所 示，本發明之冷卻裝置也可應用於螺帽（丄〇 )上，其冷 卻裝置應用於螺帽（1〇 )的裝配方式為，係於螺帽（工 0 )端面加工數個軸向流道（；[〇 2 ),其軸向流道（工 0 2)之排列方式主要環繞螺帽螺紋溝槽（i 〇 3 )排列， 如圖五所示，此排列方式主要使軸向流道（1 〇 2)能盡 i接近發熱源，使冷卻液可充分吸收熱源，加速散熱；另 外螺帽（10)冷卻裝置別於螺桿（5)冷卻裝置之部分， 在於螺帽（1 〇 )徑向設有數個徑向迴流孔（1 〇 1 )如 圖五所示，其徑向迴流孔（1 01)目的在於，係使相互 平行之軸向流道（1 〇 2)形成一循環迴路；而後，將擾 ML元件（8 0 )裝设於軸向流道（1 Q 2 )中，其擾流元 件（8 0)功用與優點第一實施例相同，在此不再多作贅 述； 在此必須說明本發明之冷卻裝置必要元件冷卻機（2 1300375 〇 ) ’其與螺捍（5 )、螺帽（ 夕 r 〇 π , „ 1 υ)之k配關係，冷卻機 、^ )為習知常見冷卻裝置之分生 (ο η Ί Λ 义要兀件，其利用導流管 、匕◦ 1 )與螺桿（5 )、螺帽（〗n、 i ί Λ 1 Λ ( 1 〇)之軸向流道（5 上0 2 )接合’形成一封閉夕、人々 裝 # f閉之冷邠迴路，其螺桿（5 ) 衣配方式係於，螺桿（5) $缸 A物、卢认 ）軸向流道（51 ) —端安裝 7郃液之輸入端（ί N)，相對 Ί , ^ 耵螺杯（5)之軸向流道（5 -端就為冷卻液之輸“（qut);再者，螺帽 」0)裝配方式係於，螺帽（ί〇)之循環路徑之-端 女衣冷卻液之輸入端（IN)，相對螺帽 環 路徑另-端就為冷卻液之輪“（qUT)，以上為树 明冷部裝置螺桿（5)與螺帽（1Ό)之裝配說明； 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： 1.本發明之滾珠螺桿冷卻裝置，其主要利用螺桿與螺帽所 剩空間，加工冷卻迴路，不需太多元件配合，故其加工 時間及成本相對降低。 2·本發明之滾珠螺桿冷卻裝置，可應用於螺桿與螺帽，使 其降溫效果更為加倍，進而提升滾珠螺桿之壽命與精 度。 3.本發明之滾珠螺桿冷卻裝置，之擾流元件方便於模具開 1300375 模，故方便大量生產。 4.本發明之滚珠螺桿冷卻裝置，該冷卻液受剖擾流元件的 • 影響，其不僅充分吸收熱源，立流動噸暢，進而將熱源 迅速帶走，故可提升其冷卻效果。 “ 5.本發明之滾珠螺桿冷卻裝置，擾流元件材質為撓性材 質，且在一定規格範圍内的冷卻流道時可共用，具有相 當的通用性。 綜上所述，本發明係利用設有嫘旋葉片之摄流元件，裝 設於螺桿與螺帽冷卻流道中，其擾流元件之目的，使冷卻 液受擾流元件螺旋流道的作用，而產生螺旋狀的流動前 進，則可增加其吸熱面積充分的帶走熱源，進一步即可提 升其冷卻效果；另外值得一提的是冷卻裝置構造簡單，不 需複雜之配件搭配，主要利用螺桿與嫘帽所剩空間，以不 • 影響螺桿與螺帽之強度為原則，來加工冷卻流道；其上述 擾机元件材質為撓性材質，開模時可旋轉脫模，易於製造 虽產，且在一疋規格範圍内的冷卻流道時可共用，具有相 田的通用性’故本發明不但改善習知冷卻裝置之缺點、且 又"』、、加了尚通用性與易於製造量產之優點；所以本發明之『具 有j業之可顧性』應已毋庸置疑，除此之外，在本案實施例所 揭路出的特徵触’於中請之前並未曾見於諸刊物，亦未曾被公 11 1300375 開使用，不但具有如上所述功效增進之事實，更具有不可輕忽的 附加功效，是故，本發明的『新穎性』以及『進步性』都已符合 專利法規，爰依法提出發明專利之申請，祈請惠予審查並早曰賜 准專利，實感德便。improve. For the purpose of improvement, the bead screw material will be equipped with a cooling device in the screw and the nut to improve the frictional high temperature generated under high speed and high load conditions, thereby reducing the ball screw temperature; however, different materials have defects. Existence, so 'how to improve the cooling device development and become more competitive has become the focus of the current industry. A conventionally known cooling device, such as the Japanese Patent Laid-Open No. 63-1956, is provided with a cooling circulation path at the periphery of the nut, and a cooling path communicating with each other is also provided on the nut seat to make the cooling paths of the two. The cooling circulation path is formed, such a cooling circulation path is rather cumbersome, and the cooling circulation path must be processed on the nut seat, which relatively increases the processing difficulty and cost, and the cooling liquid convection effect is not good, so the cooling is uneven, and Directly affects the effect of cooling. Another example is Japanese Patent Laid-Open No. 11-333666, which is equipped with a cooling device at the front and rear ends of the nut. The cooling device is a method for generating a convection by using air convection to achieve cooling, but adopting air convection at both ends of the nut. The heat source that can be taken away is effective, directly affects the cooling effect, and it cannot penetrate into the inside of the nut, which is likely to cause uneven cooling, and is necessary for further improvement. Furthermore, as disclosed in Japanese Patent No. 3721264, a cooling passage is provided on the screw shaft, the nut and the motor base, and is designed as a circulating cooling circuit, which is cooled by the coolant temperature adjusting device to achieve cooling. The effect, but due to the cooling of the cooling fluid, once the sealing structure fails, it will lead to the overflow of the coolant, which will cause environmental pollution. The common problem with the aforementioned patents is that the flow rate of the coolant is slow due to its inability to effectively approach the heat source, and the flow rate of the coolant is completely determined by the output force of the cooling device, and only the coolant periphery The edge is available for heat absorption, so the overall cooling effect is not good, and the heat dissipation rate is slow. In addition, some existing designs have complicated structures and are not well manufactured. 1300375 causes inconvenience in assembly, and invisible The cost of manufacturing it from Qiao. Change & 'The existing nut, person, ^ 々 structure due to: & coolant flow rate is slow, and only the outer edge can be money and w county from 1 picking 旲, ra at you Vw, ..., 'affects its cooling speed and effect, so if the speed of the cooling liquid can be accelerated, and the cooling liquid is disturbed, the heat absorption area and the enthalpy can be increased, and * Eight sisters, such as m and degree, can further enhance their cooling effect, and the present invention is used for achieving this one purpose. SUMMARY OF THE INVENTION Based on the above-mentioned conventional improvement of the ball screw cold skin, the inventors have succeeded in achieving the disadvantages of the present invention.
