注入容置空間22内，由於供液孔2121位於轴承12之上方，因此 冷卻液會因重力影響朝向下方落下，俾使冷卻液經由軸承12之内 襯套121與外襯套122之間落入容置空間22下方，而冷卻液再通 過内襯套121與外襯套122之間時’為會直接於内襯套a〗、外襯 套122及帶動件123接觸，而將軸承12所發出之熱源帶離，使軸 承12可快速散熱，然而由於軸承12之内襯套121與帶動件 為决速樞轉’所以冷卻液流錄承12之速率會受聰響而緩慢， 由於軸承12下方之泵葉輪23為會於轉軸Η樞轉時隨之， 使軸承12上方與下方產生壓力差，且泵葉輪23處與出液管321 内也會形成壓力差’進而使冷卻液可快速的通過軸承丨2並進入出 "1再者’泵葉輪23之葉片231會以離心力將潤滑油加壓 送入出^皆32卜並由出液管321流出容置空間四，而由出液管 321所流出之冷卻液，會經過冷卻器322之冷卻後流至儲液槽33 儲存’々藉此’轴承12即可受到冷卻液之作用，使運轉溫度保持在 範圍内進而防止轴承12發生無法枢轉之情形；再者，談A 帶動件123編套121及外細2之潤滑效果 ^ 12之磨耗，延長軸承12之使用壽命。 °月參閱第六圖所示，由圖中可清楚看出，該冷卻裳置3之出 6 201122264 液迴路32為於出液管321上裝設空氣喷射管咖，並於轴承η 下方裝設甩油環24，俾使空氣喷射管323於運作時，使出液管32i •、内之動與容置空間22内之壓力，產生更大的壓力差，進而加快 •冷⑽舰谷置㈣22之速度，而冷卻液之流速加快使單位時間 内，流經轉轴U之冷卻液的量也相對變大，進而可更加快速的使 軸承12降低工作溫度。 再請參閱第七圖所示，由圖中可清楚看出，本發明座體Μ之 上盘212外側所設置之供液孔212卜為一個以上間隔設置，俾俄 冷卻液可_由軸承12上方不同位置處麵轴承12流動更加 快速的使軸承12冷卻。 請同時參閱第人圖至第十―圖所示，由圖中可清楚看出，本 發明座體21之基座211下方與上蓋212之_邊上分別設有供液 孔212卜且供液孔2121之另侧側邊分別設有相對於供液孔⑽ 孔2出’而軸承12上下二侧分別設置有相對之栗葉輪23， 各泵葉輪23為套設於轉轴11外緣，俾使本發明於連接冷卻裝置3 時疋位裝置2之座體21可傾斜或是轉使用（如第九圖至 十-圖所不）’囉的使冷卻液皆可流經軸承1 12降溫。 以了神氓 她爾根婉，其關鍵技術 ，本發明為利用冷卻液持續流經軸承12之内襯套⑵盘外 襯套122之間，俾使冷卻液可有效的將轴承12於工作時所產生之 熱能迅速的帶離，俾使軸承12在轉軸^之高轉逮下，可有 201122264 降低工作,皿度’以防止軸承12發生因熱脹而無法框轉之情形，再 者’本發明亦咖冷卻液增加帶動件123與内襯套121及外概套 122之潤滑效果’以降低軸承12之磨耗，延長轴承12之使用壽命。 【圖式簡單說明】 ‘ 第―圖係為本發明較佳實施例之局部剖面立體圖。 第二圖係為本發明較佳實施例之側視剖面圖。 第二圖係為本發明較佳實施例之侧視分解圖。 _第四圖係為本發明較佳實施例泵葉輪之立體外觀圖。 第五圖係為本發明較佳實施例於連接冷卻裳置使用時之示意圖 (一）。 第六圖係為本發明較佳實施例於連接冷卻裝置使用時之示意圖 (二）。 第七圖係為本發明再一較佳實施例之側視剖面圖。 第八圖係為本發明又一較佳實施例之側視到面圖。 籲第九圖係為本發明又一較佳實施例於連接冷卻装置使用時之示意 圖（一）。 第十圖係為本發明又一較佳實施例於連接冷卻裝置使用時之示意 .圖（二）。 第十-隱為本發明又—較佳實關於連接冷卻裝置使用時之示 意圖（三）。 【主要元件符號說明】 1、樞轉裝置 201122264 11、 轉軸 12、 轴承 121、 内襯套 122、 外襯套 123、 帶動件 13、 固定元件 14、 轴承華司 2、定位裝置 21、座體 211、 基座 2111、出液孔 212、 上蓋 2121、供液孔 • 22、容置空間 23、泵葉輪 231、葉片 - 24、甩油環 3、冷卻裝置 31、供液迴路 311、供液管 201122264 312、幫浦 32、 出液迴路 321、 出液管 322、 冷卻器 323、 空氣喷射管 33、 儲液槽In the accommodating space 22, since the liquid supply hole 2121 is located above the bearing 12, the coolant falls downward due to the influence of gravity, so that the coolant falls between the inner bush 121 and the outer bush 122 of the bearing 12. Below the accommodating space 22, when the coolant passes between the inner bushing 121 and the outer bushing 122, it is directly contacted with the inner bushing a, the outer bushing 122 and the driving member 123, and the bearing 12 is issued. The heat source is removed to allow the bearing 12 to dissipate quickly. However, since the bushing 121 and the driving member of the bearing 12 are pivoted at a constant speed, the rate of the coolant flow recording 12 is slow and slow due to the bearing 12 When the pump impeller 23 pivots on the rotating shaft, a pressure difference is generated between the upper and lower sides of the bearing 12, and a pressure difference is formed between the pump impeller 23 and the outlet pipe 321 to further allow the coolant to pass quickly. The bearing 丨2 enters the "1 and then the blade 231 of the pump impeller 23 will pressurize the lubricating oil into the outlet 32 by centrifugal force and flow out of the accommodating space 4 from the outlet pipe 321 by the outlet pipe The coolant flowing out of 321 is cooled by the cooler 322 and then flows to the reservoir. The groove 33 stores the 'turning' bearing 12 to be subjected to the action of the cooling liquid, so that the operating temperature is kept within the range to prevent the bearing 12 from being unable to pivot; and further, the A driving member 123 is sleeved 121 and the outer thin 2 The lubrication effect ^ 12 wear, prolong the service life of the bearing 12. ° ° see the sixth figure, as can be clearly seen from the figure, the cooling skirt 3 out of the 6 201122264 liquid circuit 32 is installed on the outlet pipe 321 air jet pipe, and installed under the bearing η The oil slinger 24, when the air injection pipe 323 is in operation, causes the pressure in the liquid discharge pipe 32i, the inner movement and the accommodating space 22 to generate a larger pressure difference, thereby accelerating the cold (10) ship valley (four) 22 The speed of the coolant and the flow rate of the coolant are increased so that the amount of the coolant flowing through the shaft U is relatively large per unit time, so that the bearing 12 can be lowered in temperature more quickly. Referring to FIG. 7 again, it can be clearly seen from the figure that the liquid supply holes 212 disposed on the outer side of the upper tray 212 of the present invention are arranged at more than one interval, and the coolant can be cooled by the bearing 12 The surface bearing 12 flows at different positions above to more quickly cool the bearing 12. Please also refer to the figure of the person to the tenth-figure, as is clear from the figure, the bottom of the base 211 of the seat 21 of the present invention and the side of the upper cover 212 are respectively provided with a liquid supply hole 212 and liquid supply. The other side of the hole 2121 is respectively provided with respect to the hole 2 of the liquid supply hole (10), and the upper and lower sides of the bearing 12 are respectively provided with opposite chestnut impellers 23, and the pump impellers 23 are sleeved on the outer edge of the rotating shaft 11, When the present invention is connected to the cooling device 3, the seat body 21 of the clamping device 2 can be tilted or used (as shown in the ninth to tenth drawings), so that the cooling liquid can be cooled through the bearing 1212. With the key technology of the Hercules, the present invention utilizes a coolant to continuously flow between the inner bushings (2) of the outer bushings 122 of the bearing 12, so that the coolant can effectively hold the bearing 12 during operation. The generated heat energy is quickly taken away, so that the bearing 12 can be lowered under the high rotation of the rotating shaft, and the working degree can be reduced by 201122264, so as to prevent the bearing 12 from being unable to be framed due to thermal expansion, and then The invention also increases the lubricating effect of the driving member 123 and the inner bushing 121 and the outer shroud 122 to reduce the wear of the bearing 12 and prolong the service life of the bearing 12.
