目前市面上常見的習知馬達係大致如中華民國第I391568號「馬達」發明專利案,該習知馬達包含一基座,該基座設有一軸管,該軸管內部設有一軸承,其中該軸管外部套設一定子組,該軸承可供一轉子的轉軸樞接;藉此,該定子組可產生交變磁場,用以驅動該轉子旋轉作動。又,習知馬達的軸承一般係選用含油軸承,該馬達亦配合該含油軸承設計有「潤滑循環構造」,以確保該含油軸承可有效儲存潤滑油,使該轉子可順利旋轉作動,並兼可提升馬達的使用壽命。The conventional motor that is commonly used in the market is generally the invention patent of the motor of the Republic of China No. I391568. The conventional motor includes a base, and the base is provided with a shaft tube, and the shaft tube is internally provided with a bearing, wherein the bearing The outer portion of the shaft tube is sleeved with a certain subset, and the bearing is pivotally connected to a rotating shaft of the rotor; thereby, the stator group can generate an alternating magnetic field for driving the rotor to rotate. Moreover, the bearings of the conventional motor are generally selected from oil-impregnated bearings, and the motor is also designed with a "lubrication cycle structure" to ensure that the oil-impregnated bearing can effectively store lubricating oil, so that the rotor can be smoothly rotated and can be used. Improve the life of the motor.
請參照第1圖所示,係揭示一種習知馬達潤滑循環構造8,該習知馬達潤滑循環構造8具有一基座81,該基座81設有一軸管811,該軸管811內部設置一軸承82及一封閉件83,該軸承82可供一轉軸84樞接;其中該軸承82之外周面設有數個導油溝821,藉此,該軸管811內部可形成供潤滑油循環流動的油路,該油路係由「軸承82與軸管811之間」、「軸承82與轉軸84之間」、以及「封閉件83所封閉的軸管811空間」所共同構成,且該轉軸84與該軸承82之間可藉由潤滑油以形成一油膜85,用以提供潤滑功能進而增加馬達使用壽命。Referring to FIG. 1, a conventional motor lubrication cycle structure 8 is disclosed. The conventional motor lubrication cycle structure 8 has a base 81. The base 81 is provided with a shaft tube 811, and the shaft tube 811 is internally provided with a shaft 811. a bearing 82 and a closing member 83, the bearing 82 is pivotally connected to a rotating shaft 84. The outer peripheral surface of the bearing 82 is provided with a plurality of oil guiding grooves 821, whereby the inner portion of the shaft tube 811 can be formed to circulate lubricating oil. In the oil passage, the oil passage is composed of "between the bearing 82 and the shaft tube 811", "between the bearing 82 and the rotating shaft 84", and "the space of the shaft tube 811 closed by the closing member 83", and the rotating shaft 84 is formed. An oil film 85 may be formed between the bearing 82 and the lubricating oil to provide a lubricating function to increase the service life of the motor.
然而,由於習知馬達潤滑循環構造8之油路的儲存空間較小,當該轉軸84組裝於該軸管811時,該轉軸84容易將該軸承82內部的 殘留空氣擠出,同時,一部分的潤滑油亦會自該油路中溢出,故相對容易產生漏油情形,而大幅降低馬達的使用壽命。However, since the storage space of the oil passage of the conventional motor lubrication circulation structure 8 is small, when the rotation shaft 84 is assembled to the shaft tube 811, the rotation shaft 84 is easy to be inside the bearing 82. Residual air is squeezed out, and at the same time, a part of the lubricating oil will overflow from the oil path, so it is relatively easy to cause oil leakage and greatly reduce the service life of the motor.
請參照第2圖所示,係揭示另一種習知馬達潤滑循環構造9 ,該習知馬達潤滑循環構造9同樣具有一基座91,該基座91設有一軸管911,該軸管911內部設置一軸承92及一封閉件93,該軸承92可供一轉軸94樞接,且該軸承92之外周面設有數個導油溝921。該另一種習知馬達潤滑循環構造9為改善上述習知馬達潤滑循環構造8的問題,其主要係加寬該數個導油溝921,藉此,使油路的儲存空間相對增加,潤滑油較不會充滿整個油路,且該油路相對具有較多空氣。Referring to Figure 2, another conventional motor lubrication cycle configuration is disclosed. The conventional motor lubrication circulation structure 9 also has a base 91. The base 91 is provided with a shaft tube 911.

A plurality of oil guiding grooves 921 are provided on the outer circumferential surface of the bearing 92. The other conventional motor lubrication cycle structure 9 is a problem of improving the above-described conventional motor lubrication cycle structure 8, which mainly widens the plurality of oil guiding grooves 921, thereby increasing the storage space of the oil passage, and lubricating oil. It does not fill the entire oil circuit, and the oil path has relatively more air.
然而,該另一種習知馬達潤滑循環構造9雖然可解決上述習 知馬達潤滑循環構造8容易產生漏油的問題,但當該油路存在過多的空氣時,反而容易另外造成該油路內部油壓減弱,進而導致該轉軸94與該軸承92之間所形成的油膜95強度不足,如此一來,導致該油膜95無法提供該轉軸94較佳的潤滑功能,使該轉軸94於轉動過程中容易與該軸承92產生過多接觸或摩擦,進而產生噪音。However, this other conventional motor lubrication cycle configuration 9 can solve the above It is known that the motor lubrication circulation structure 8 is prone to oil leakage. However, when there is excessive air in the oil passage, it is easy to cause the oil pressure inside the oil passage to be weakened, thereby causing the formation between the rotating shaft 94 and the bearing 92. The oil film 95 is insufficient in strength, and as a result, the oil film 95 cannot provide a better lubricating function of the rotating shaft 94, so that the rotating shaft 94 easily generates excessive contact or friction with the bearing 92 during the rotating process, thereby generating noise.

藉由上述馬達潤滑循環構造,由於該軸管11的內周面與該 軸承2的外周面之間設有該軸套4,該軸套4可用以遮斷該軸承2外周面,使得用以供潤滑油循環流動的該油路(由該第一油道R1及該第二油道R2所構成)是形成於該軸套4內部,以防止該油路存在過多的空氣,進而有效維持該轉軸3與該軸承2之間所形成的油膜強度,另配合該軸套4連通該油路的設計,當該油路的潤滑油過多時,該通氣槽41亦可作為多餘潤滑油的儲存場所,以避免產生漏油情形,使該馬達潤滑循環構造可以提供該轉軸3良好的潤滑功能,並隨時可供給潤滑油至該油路,以維持該軸承2的正常運作,進而達到提升馬達使用壽命之功效。By the motor lubrication circulation structure described above, due to the inner circumferential surface of the shaft tube 11 and the The sleeve 4 is disposed between the outer peripheral surfaces of the bearing 2, and the sleeve 4 can be used to block the outer peripheral surface of the bearing 2, so that the oil passage for circulating lubricating oil (from the first oil passage R1 and the The second oil passage R2 is formed inside the sleeve 4 to prevent excessive air in the oil passage, thereby effectively maintaining the oil film strength formed between the rotating shaft 3 and the bearing 2, and further matching the sleeve 4 communicating with the design of the oil passage, when the lubricating oil of the oil passage is excessive, the venting groove 41 can also serve as a storage place for excess lubricating oil to avoid oil leakage, so that the motor lubrication circulation structure can provide the rotating shaft 3 Good lubrication function and ready to supply lubricating oil to the oil circuit to maintain the normal operation of the bearing 2, thereby improving the service life of the motor.
又,藉由上述馬達潤滑循環構造的軸套4設計,由於該軸套 4可用以遮斷該軸承2外周面,使得用以供潤滑油循環流動的該油路(由該第一油道R1及該第二油道R2所構成)是形成於該軸套4內部,因而確保潤滑油的填入可以優先填滿於該軸承2與該轉軸3之間,以有效維持該轉軸3與該軸承2之間所形成的油膜強度,使該轉軸3相對該軸承2進行旋轉的過程中,該油膜可以充分潤滑該轉軸3,避免該轉軸3於轉動過 程中與該軸承2形成過多接觸或摩擦,以達到防止轉軸於轉動過程中產生噪音之功效。Moreover, the sleeve 4 is designed by the above motor lubrication circulation structure, because the sleeve 4 can be used to block the outer peripheral surface of the bearing 2 such that the oil passage for circulating lubricating oil (consisting of the first oil passage R1 and the second oil passage R2) is formed inside the sleeve 4 Therefore, it is ensured that the filling of the lubricating oil can be preferentially filled between the bearing 2 and the rotating shaft 3 to effectively maintain the oil film strength formed between the rotating shaft 3 and the bearing 2, and the rotating shaft 3 is rotated relative to the bearing 2. In the process, the oil film can fully lubricate the rotating shaft 3, and the rotating shaft 3 is prevented from rotating. During the process, excessive contact or friction is formed with the bearing 2 to prevent the shaft from generating noise during the rotation.
