具潤滑防漏結構之線性滑軌Linear slide with lubricated leakproof structure

    本創作係為一種線性傳動元件，尤指一種具潤滑油路之線性滑軌。
This creation is a linear transmission component, especially a linear slide with a lubricating oil path.

    請參閱圖九至圖十所示係為習知的線性滑軌之潤滑油路的剖視圖及線性滑軌之組合圖；線性滑軌係包含：一軌條(1)，其延一方向伸長為長條狀之構型；一滑塊(2)，其套設於該軌條(1)；兩端蓋(3)，係分別蓋設於該滑塊(2)之兩端面(23)，該端蓋(3)係設有注油道(32)及複數油路(33)，該注油道(32)係貫穿該端蓋(3)，該注油道(32)一端係提供一油嘴(5)固定，另一端係與該油路(33)連通，該油嘴(5)係設有一與該注油道(32)連通之通道(51)；而當滑塊(2)於該軌條(1)上運行時，係藉由滑塊(2)與軌條(1)之間設置的滾動體作為之間的傳動介質，使滑塊(2)與軌條(1)的摩擦阻力減少，而於滑塊(2)運行時必須提供充足的潤滑油來潤滑該滾動體，使滾動體的使用壽命延長並提升其順暢度。
    然而，以此種潤滑結構的結構設計，該注油道(32)與該油路(33)皆為開放之型態，該注油道(32)與該油路(33)必須與該滑塊(2)之端面(23)配合後才會形成封閉之型態，而此種配合方式於潤滑油注入該通道(51)再進入該注油道(32)時(潤滑油注入方式以加壓油槍或幫浦輔助注油)，會因為潤滑油注入的壓力過大，且該注油道(32)又與潤滑油之壓力方向平行，故潤滑油係直接衝擊該滑塊(2)端面(23)，使得潤滑油由端蓋(3)與滑塊(2)之端面(23)間隙處滲出來(如第十圖之元件符號(90)滲油處)，而滲出位置係鄰近於該注油道(32)，而滲出的潤滑油會造成周邊環境的汙染；且會讓潤滑油填充不足，因為如果以自動供油系統來說，都是以定時定量來補給潤滑油，故如果每次都會造成潤滑油滲出，相對的會使得潤滑油補給不足；另外，以人工補給亦同，雖然不是定時定量，但是滑塊的安裝位置通常被其承載物遮蔽住了，故潤滑油是否滲出並無法以肉眼觀察得知，必須移開承載物才能得知，但移開承載物是件費時費力的事，故亦無法確定潤滑油是否補給充足，是以，此種習知的技術仍有改良精進之必要。
Please refer to the sectional view of the lubricating oil circuit of the conventional linear slide and the combination of the linear sliding rails shown in FIG. 9 to FIG. 10; the linear sliding rail system comprises: a rail (1) which is extended in one direction. a strip-shaped configuration; a slider (2) sleeved on the rail (1); and two end covers (3) respectively disposed on opposite end faces (23) of the slider (2), The end cap (3) is provided with a oil filling passage (32) and a plurality of oil passages (33). The oil filling passage (32) extends through the end cover (3), and one end of the oil filling passage (32) is provided with a grease nipple (5). Fixed, the other end is in communication with the oil passage (33), the grease nipple (5) is provided with a passage (51) communicating with the oil fill passage (32); and when the slider (2) is at the rail (1) When running up, the frictional resistance between the slider (2) and the rail (1) is reduced by the rolling elements provided between the slider (2) and the rail (1) as the transmission medium between the sliders (2) When the slider (2) is running, sufficient lubricating oil must be provided to lubricate the rolling elements to extend the service life of the rolling elements and improve their smoothness.
However, with the structural design of the lubricating structure, the oil filling passage (32) and the oil passage (33) are both open, and the oil filling passage (32) and the oil passage (33) must be connected to the sliding block ( 2) The end face (23) will form a closed shape when it is fitted, and this kind of cooperation means when the lubricating oil is injected into the passage (51) and then enters the oil filling passage (32) (the lubricating oil injection method is a pressurized oil gun). Or the auxiliary oil injection of the pump), because the pressure of the lubricating oil injection is too large, and the oil filling passage (32) is parallel to the pressure direction of the lubricating oil, the lubricating oil directly impacts the end surface (23) of the sliding block (2), so that The lubricating oil is oozing out from the gap between the end cover (3) and the end face (23) of the slider (2) (as shown in the symbol (90) of the tenth figure), and the oozing position is adjacent to the oil filling passage (32). ), and the oozing oil will cause pollution to the surrounding environment; and it will make the lubricating oil insufficiently filled, because if the automatic oil supply system is used to replenish the lubricating oil at a certain time, it will cause lubricating oil every time. Exudation, the relative will make the lubricant supply insufficient; in addition, the artificial replenishment is the same, although not the timing quantitative, but the slider The loading position is usually covered by its load, so whether the lubricating oil seeps out and can not be seen by the naked eye, the carrier must be removed to know, but removing the carrier is a time-consuming and laborious task, so it is impossible to determine the lubrication. Whether the oil is adequately replenished is such a technique that is still necessary for improvement.
