Description
本創作係有關於一種馬達相關之技術領域,尤其是指用一種馬達冷卻液甩油迴流裝置。 This creation relates to a motor-related technical field, and in particular to the use of a motor coolant slick return device.
請參閱第7、8圖所示,習知馬達結構具有一外殼體91、一定子92、一轉子93、一前端蓋94、一後端蓋95、及一油盆96。 Referring to Figures 7 and 8, the conventional motor structure has an outer casing 91, a stator 92, a rotor 93, a front end cover 94, a rear end cover 95, and an oil basin 96.
前述外殼體91係為一中空管狀體,頂、底兩端分別有一注油孔912及一洩油孔914,以連通外殼體91內部及外部。 The outer casing 91 is a hollow tubular body, and the top and bottom ends respectively have an oil hole 912 and an oil drain hole 914 for connecting the inside and the outside of the outer casing 91.
前述定子92與轉子93係同心套銜並容置於外殼體91內。 The stator 92 and the rotor 93 are concentrically nested and housed in the outer casing 91.
前述前、後端蓋94、95係對應外殼體91前、後端截面封設,分別具有一同心貫穿之前、後端蓋軸孔942、952,分別提供轉子93之轉軸932穿伸。 The front and rear end covers 94 and 95 are correspondingly arranged in front and rear end portions of the outer casing 91, and have a concentric inner and rear end cover shaft holes 942 and 952 respectively, respectively, and the rotation shaft 932 of the rotor 93 is respectively provided.
前述油盆96係設於外殼體91之底端,並與洩油孔914位置對應。 The oil basin 96 is disposed at the bottom end of the outer casing 91 and corresponds to the position of the drain hole 914.
如上所述之結構,透過注油孔911引入冷卻液(潤滑油)至外殼體91內部進行熱交換後,其冷卻液(潤滑油)經由洩油孔914離開外殼體91至油盆96蓄存,可選擇性的配合過濾(冷 卻)設備將油盆96中之冷卻液(潤滑油)進行冷卻(過濾),待後續循環回流到注油孔912,藉此對馬達內之構件進行冷卻(潤滑)。 According to the configuration described above, after the coolant (lubricating oil) is introduced into the outer casing 91 through the oil hole 911 for heat exchange, the coolant (lubricating oil) is discharged from the outer casing 91 to the oil pan 96 via the drain hole 914. Optional filter (cold However, the device cools (filters) the coolant (lubricating oil) in the oil pan 96 and waits for subsequent circulation to return to the oil filling hole 912, thereby cooling (lubricating) the components in the motor.
為了避免冷卻液(潤滑油)經由前(後)端蓋94(95)之前(後)端蓋軸孔942(952)外漏,故前(後)端蓋軸孔942(952)都必需配合一油封環97設置。該油封環97具有一貫孔972,套銜於轉軸932外周側,並固設於前(後)端蓋94、95,藉以達成防漏之效益,然其結構存有以下缺失;習知之油封環97多為(或包含)塑膠材質,周知塑膠材質其耐油不佳,容易硬化失去物理變形之彈性。 In order to prevent the coolant (lubricating oil) from leaking through the front (rear) end cap shaft hole 942 (952) of the front (rear) end cap 94 (95), the front (rear) end cap shaft hole 942 (952) must be matched. An oil seal ring 97 is provided. The oil seal ring 97 has a constant hole 972, is sleeved on the outer peripheral side of the rotating shaft 932, and is fixed to the front (rear) end covers 94, 95, thereby achieving the leakage prevention effect, and the structure has the following defects; the conventional oil seal ring More than 97 (or include) plastic materials, known as plastic materials, its oil resistance is not good, easy to harden the elasticity of physical deformation.
習知之油封環97與轉軸932形成輕微的接觸,故此一接觸面,必然因與高速旋轉之轉軸932接觸而磨損,導致轉軸931穿伸之貫孔972孔徑擴大,而失去密封的效果。 The conventional oil seal ring 97 forms a slight contact with the rotating shaft 932. Therefore, the contact surface is inevitably worn due to contact with the rotating shaft 932 rotating at a high speed, so that the hole 972 through which the rotating shaft 931 penetrates has an enlarged aperture and loses the sealing effect.
承上所述,習知油封環97係與轉軸932形成接觸,一旦有灰塵或其它硬質廢屑卡阻於油封環97與轉軸932之間時,反容易對轉軸932表面形成定點之磨損。 As described above, the conventional oil seal ring 97 is in contact with the rotating shaft 932. When dust or other hard waste is caught between the oil seal ring 97 and the rotating shaft 932, it is easy to form a fixed point on the surface of the rotating shaft 932.
有鑑於上述習知技藝之問題與缺失,本創作之主要目的,乃在於提供一種馬達冷卻液甩油迴流裝置,透過結構金屬材質之設計,使其兼具甩油及迷宮防漏之效益,以克服上述習知技藝之缺失。 In view of the above problems and shortcomings of the prior art, the main purpose of the present invention is to provide a motor coolant slick backflow device, which is designed to have the benefits of simmering oil and labyrinth leakage through the design of the structural metal material.

是以,上述即為本創作所提供一較佳實施例馬達冷卻液甩油迴流裝置各部構件及組裝方式之介紹,茲再將本創作之實施例作動特點介紹如下。 Therefore, the above description is a description of the components and assembly methods of the motor coolant hydrazine reflow device according to a preferred embodiment of the present invention. The actuation characteristics of the embodiment of the present invention are described below.
請參閱第1至6圖所示,冷卻液(潤滑油)自注油孔112以油氣形態注入外殼體11內,對外殼體11內之構件進行熱交換(潤滑),各軸承6軸向內端面(遠離甩油軸套5)之冷卻液(潤滑油)會因自重朝洩油孔114方向運動。 Referring to FIGS. 1 to 6, the coolant (lubricating oil) is injected into the outer casing 11 in the form of oil and gas from the oil filling hole 112, and heat exchange (lubrication) is performed on the members in the outer casing 11, and the axial inner end faces of the respective bearings 6 are provided. The coolant (lubricating oil) (away from the sling bushing 5) will move toward the drain hole 114 due to its own weight.
另各軸承6軸向外端面(抵接甩油軸套5)之冷卻液(潤滑油)溢出至甩油軸套5時,由於甩油軸套5與轉軸132同動故對冷卻液(潤滑油)形成拋甩的作用,使流至甩油軸套5之冷卻液(潤滑油)被拋甩到前(後)端蓋14(15)之前(後)端蓋軸孔142(152)孔壁及迷宮軸蓋4之內環槽44槽壁,大幅提升主動回油能力並可防止洩漏。 When the coolant (lubricating oil) of the axially outer end surface of each bearing 6 (abutting the oil sling bushing 5) overflows to the oil sling bushing 5, since the slinger bushing 5 and the rotating shaft 132 move together, the coolant (lubrication) The oil) forms a throwing action, so that the coolant (lubricating oil) flowing to the oil sling sleeve 5 is thrown to the front (rear) end cover 14 (15) before (rear) the end cap shaft hole 142 (152) hole The inner wall of the ring groove 44 in the wall and labyrinth shaft cover 4 greatly enhances the active oil returning ability and prevents leakage.
被拋甩到迷宮軸蓋4內環槽44之冷卻液(潤滑 油),會因自重(聚合)而沿內環槽44流到迴流道3,並經迴流道3朝洩油孔114方向運動。另外甩油軸套5之翼部54(延伸段542及垂直段544)容置於迷宮軸蓋4內環槽44小徑段之階級446處,利用甩油軸套5旋轉時造成周邊流體壓力的變化,即可形成隱形的防護,再配合翼部54與迷宮軸蓋4內環槽44對應之端面大、小徑段之階級444、446,共同界定出一道多段曲折之迷宮通道A,俾以達成止洩漏之效益。 Coolant that is thrown into the inner ring groove 44 of the labyrinth shaft cover 4 (lubricated The oil) flows to the return passage 3 along the inner ring groove 44 due to its own weight (polymerization), and moves toward the drain hole 114 through the return passage 3. In addition, the wing portion 54 (the extension portion 542 and the vertical portion 544) of the oil sling sleeve 5 is received in the step 446 of the small diameter section of the annular groove 44 in the labyrinth shaft cover 4, and the peripheral fluid pressure is caused by the rotation of the oil sling sleeve 5. The change can form an invisible protection, and the wing portion 54 and the end face large and small diameter segments 444 and 446 corresponding to the inner ring groove 44 of the labyrinth shaft cover 4 jointly define a plurality of labyrinth passages A, 俾In order to achieve the benefits of leakage.
故緃使冷卻液(潤滑油)由上方(趨近注油孔112方向)進入曲折之迷宮通道A時,仍會積存於內環槽44之銳角部442中,並沿銳角部442自動經內環槽44外徑側之大、小徑段之階級444、446,而朝洩油孔114方向運動。 Therefore, when the coolant (lubricating oil) enters the meandering labyrinth passage A from above (in the direction of the oil filling hole 112), it still accumulates in the acute corner portion 442 of the inner ring groove 44, and automatically passes through the inner ring along the acute corner portion 442. The large and small-diameter sections 444 and 446 of the outer diameter side of the groove 44 move toward the drain hole 114.
以上所述說明,僅為本創作的較佳實施方式而已,意在明確本創作的特徵,並非用以限定本創作實施例的範圍,本技術領域內的一般技術人員根據本創作所作的均等變化,以及本領域內技術人員熟知的改變,仍應屬本創作涵蓋的範圍。 The above description is only for the preferred embodiment of the present invention, and is intended to clarify the features of the present invention, and is not intended to limit the scope of the present embodiment, and the average variation made by those skilled in the art according to the present creation. Changes that are well known to those skilled in the art, and still fall within the scope of this creation.
