Description
本發明是有關於一種油路導引裝置,特別是指一種導引潤滑油的迴轉體油路導引裝置。The present invention relates to an oil passage guiding device, and more particularly to a rotary body oil passage guiding device for guiding lubricating oil.
迴轉體油路導引裝置一般用於對一旋轉裝置進行潤滑時使用。參閱圖1,一種迴轉體油路導引裝置1的習知包含一兩端開口的桶體11、一設置於桶體11的其中一開口的蓋子12、一樞設於桶體11內並可與旋轉裝置連接的旋轉軸13,及一套設於該旋轉軸13外周面的內襯14。桶體11上形成一第一入口111。蓋子12上形成一第二入口121。旋轉軸13形成一自外露於桶體11外的端面延伸至旋轉軸13的外周面並且與桶體11的第一入口111相對應的第一導入管道131、複數個呈環狀排列且貫穿旋轉軸13並與蓋子12的第二入口121相互連通的第二導出管道132。旋轉軸13的外周面形成一與第一導入管道131相連通的儲存環槽133。內襯14套設於旋轉軸13外周面且形成一連通第一入口111及儲存環槽133的穿孔141。The rotary oil passage guide is generally used for lubricating a rotating device. Referring to FIG. 1 , a revolving oil passage guiding device 1 includes a barrel 11 having an open end, a cover 12 disposed at one of the openings of the barrel 11 , and a pivoting member 11 . A rotating shaft 13 connected to the rotating device, and a set of the inner liner 14 provided on the outer peripheral surface of the rotating shaft 13. A first inlet 111 is formed in the barrel 11. A second inlet 121 is formed in the cover 12. The rotating shaft 13 forms a first introduction duct 131 extending from an end surface exposed to the outside of the tub body 11 to the outer peripheral surface of the rotating shaft 13 and corresponding to the first inlet 111 of the tub body 11, a plurality of annular arrays and a through-rotation A second outlet conduit 132 that communicates with the shaft 13 and the second inlet 121 of the lid 12. The outer peripheral surface of the rotary shaft 13 forms a storage ring groove 133 that communicates with the first introduction duct 131. The inner liner 14 is sleeved on the outer peripheral surface of the rotating shaft 13 and defines a through hole 141 that communicates with the first inlet 111 and the storage ring groove 133.
使用時,是在桶體11的第一入口111加壓,讓潤滑油自內襯14上的穿孔141因壓力差而經由旋轉軸13的第一導入管道131流入到旋轉裝置達到油路導引的目的,使用中的潤滑油於第一導入管道131中經由旋轉軸13與內襯14的間隙控制,以達到油路導引同時允許些微滲漏至第二導入管道132。而第一導入管道131是藉由儲存環槽133,才 能將潤滑油流至旋轉裝置,使潤滑油可連續的流入,但內襯14的內孔間隙會因潤滑油溫度變化導致滲漏量難以控制,且使第一導入管道131壓力不穩定。內襯14外徑尺寸設計較大,以干涉配合的方式避免輸入的潤滑油滲漏而失壓,但卻造成內襯14的內孔真圓度差且易磨耗而更換頻繁,而提高成本。In use, the first inlet 111 of the barrel 11 is pressurized, and the perforation 141 of the lubricating oil from the inner liner 14 flows into the rotating device through the first introduction duct 131 of the rotating shaft 13 due to the pressure difference to reach the oil passage guide. For the purpose, the lubricating oil in use is controlled in the first introduction duct 131 via the gap between the rotating shaft 13 and the inner liner 14 to achieve oil path guidance while allowing some microleakage to the second introduction duct 132. The first introduction duct 131 is stored by the ring groove 133. The lubricating oil can be flowed to the rotating device so that the lubricating oil can continuously flow in, but the inner hole gap of the inner liner 14 is difficult to control due to the change in the lubricating oil temperature, and the pressure of the first introduction pipe 131 is unstable. The outer diameter of the inner liner 14 is designed to be large, and the pressure of the input lubricating oil is prevented from leaking and the pressure is lost, but the inner hole of the inner liner 14 is poor in roundness and is easy to be worn and frequently replaced, thereby increasing the cost.
因此,本發明之目的,即在提供一種導引潤滑油的迴轉體油路導引裝置。Accordingly, it is an object of the present invention to provide a rotary body oil passage guide for guiding lubricating oil.

And communicating with the storage ring groove 23 of the barrel 2.

In the preferred embodiment, the sealing unit 6 includes a sealing ring seat 61 disposed in the second opening 22, and a sealing ring 62 disposed in the sealing ring seat 61. However, the sealing unit 6 is not limited thereto. As long as it is combined with the second opening 22, leakage can be avoided.
使用時,加壓的潤滑油自蓋子3的入口31流入,流經抗磨件組5的該等固定座51及抗磨件52,再流入旋轉軸4的第一導入管道43,最後導引流至與旋轉軸4的連接凸緣部46連接的旋轉裝置;而另一油路導引則是經由桶體2的側入口24將潤滑油流入儲存環槽23,再藉連通於儲存環槽23的該等第二導入管道44導引至旋轉裝置。值得一提的是,流經第二導入管道44的潤滑油部分會自側管道45流至桶體2與旋轉軸4之間用以潤滑桶體2與旋轉軸4。由於潤滑油流入時是直線流入,所以潤滑油不須以高壓施加於主入口31即能流入。In use, the pressurized lubricating oil flows in from the inlet 31 of the cover 3, flows through the fixing seats 51 of the anti-friction member group 5 and the anti-friction member 52, and then flows into the first introduction duct 43 of the rotating shaft 4, and finally guides The rotating device is connected to the connecting flange portion 46 of the rotating shaft 4; and the other oil passage guides the lubricating oil into the storage ring groove 23 via the side inlet 24 of the barrel 2, and then communicates with the storage ring groove. The second introduction ducts 44 of 23 are guided to the rotating device. It is worth mentioning that the lubricating oil portion flowing through the second introduction duct 44 flows from the side duct 45 to between the tub body 2 and the rotating shaft 4 for lubricating the tub body 2 and the rotating shaft 4. Since the lubricating oil flows in a straight line, the lubricating oil does not have to be applied to the main inlet 31 at a high pressure.
另外,由於潤滑油流入時,蓋子3的主入口31與旋轉 軸4的導入管道43維持相連通,而不會因旋轉軸旋4轉導致不連通,因此抗磨組件5的該等抗磨件52不須以干涉配合的方式來防止當潤滑油流入時滲漏而施壓,所以能大幅降低該等抗磨件52的磨耗。In addition, the main inlet 31 and the rotation of the cover 3 are due to the inflow of the lubricating oil. The introduction ducts 43 of the shaft 4 are maintained in communication without being disconnected due to the rotation of the rotary shaft 4, so that the wear members 52 of the anti-friction assembly 5 do not have to interfere with the interference to prevent leakage when the lubricating oil flows in. Since the pressure is applied by leakage, the wear of the wear resistant members 52 can be greatly reduced.
綜上所述,透過蓋子3的主入口31、桶體2的側入口24、抗磨件組5、旋轉軸4的第一導入管道43及第二導入管道44的設置,使潤滑油不需施以高壓即能不間斷地流至旋轉裝置,且能有效控制滲漏量與壓力穩定性,並降低抗磨件組5的磨耗,故確實能達成本發明之目的。In summary, through the main inlet 31 of the cover 3, the side inlet 24 of the barrel 2, the wear resistant member set 5, the first introduction duct 43 of the rotating shaft 4, and the second introduction duct 44, the lubricating oil is not required. By applying high pressure, it can flow to the rotating device without interruption, and can effectively control the leakage amount and pressure stability, and reduce the wear of the wear resistant member group 5, so that the object of the present invention can be achieved.
惟以上所述者,僅為本發明之較佳實施例而已,當不能以此限定本發明實施之範圍,即大凡依本發明申請專利範圍及發明說明內容所作之簡單的等效變化與修飾,皆仍屬本發明專利涵蓋之範圍內。The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
