Abstract
一種殼動式的立式行星齒輪減速機構,採用行星架固定,環齒輪輸出,動力的輸出不是輸出軸,而是由包含該環齒輪的外殼作為動力輸出。該減速機構只有在潤滑油位的上方需作防塵裝置防止粉塵進入,油位的下部外殼為全密閉式,故此機構在不超過正常油位使用之下,完全沒有漏油的可能性。另外,該減速機構於外殼的最高和最低點配置了兩個滾錐軸承,支點穩固特別長,可承受攪拌軸的徑向力和軸向力。因此,該減速機構不需加裝長支點支撐座、聯軸器等,減少零組件降低成本,減少整體機構體積和重量。 A shell-type vertical planetary gear reduction mechanism adopts a planetary frame fixed, a ring gear output, and the output of the power is not an output shaft, but a power output including the outer casing including the ring gear. The speed reduction mechanism only needs to be dustproof device above the lubricating oil level to prevent dust from entering. The lower outer casing of the oil level is fully enclosed, so the mechanism does not have the possibility of oil leakage under the use of the normal oil level. In addition, the speed reduction mechanism is provided with two roller cone bearings at the highest and lowest points of the outer casing, and the fulcrum is stable and particularly long, and can bear the radial force and the axial force of the agitating shaft. Therefore, the speed reduction mechanism does not need to be equipped with a long fulcrum support seat, a coupling, etc., reducing the cost of components and reducing the overall mechanism volume and weight.
Description
本發明有關於一種殼動式的立式行星齒輪減速機,其不會發生漏油現象,且具有更佳的抗軸向力、徑向力的能力。 The invention relates to a shell-operated vertical planetary gear reducer, which does not suffer from oil leakage and has better ability to resist axial force and radial force.
傳統一般的立式行星齒輪減速機採用環齒輪固定,行星架傳輸出至出力軸。此減速機必須在出力軸裝配油封來防止漏油。當該減速機在長期運轉下,該油封材質會老化,以及出力軸與油封接觸位置的磨損,就會產生漏油現象,造成環境污染。 The conventional vertical planetary gear reducer is fixed by a ring gear, and the carrier is transmitted to the output shaft. This reducer must be equipped with an oil seal on the output shaft to prevent oil leakage. When the reducer is in long-term operation, the oil seal material will age, and the wear of the output shaft and the oil seal contact position will cause oil leakage and cause environmental pollution.
當該習用的減速機用於攪拌機時,前述的漏油現象會嚴重污染要攪拌的產品,造成企業的嚴重損失。雖然有些高階減速機採用可靠性高,成本也高的機械油封(浮動油封),也是不能完全阻止漏油的情形發生。當該攪拌機所要攪拌的產品為食品、藥品時,若未及時發現漏油現象,所造成的後果更為嚴重。 When the conventional reducer is used in a mixer, the aforementioned oil leakage phenomenon will seriously pollute the product to be stirred, causing serious damage to the enterprise. Although some high-end reducers use mechanical seals (floating oil seals) with high reliability and high cost, they cannot completely prevent oil leakage. When the product to be stirred by the mixer is food or medicine, if the oil leakage phenomenon is not found in time, the consequences are more serious.
圖一所示為習用立式行星齒輪減速機的結構示意圖。該減速機包含一馬達10、一減速箱11、一聯軸器12、一出力軸13。該減速箱11內容置有行星齒輪減速機構(圖上未示出)。該聯軸器12在連接該減速箱11的動力輸出軸14與該出力軸13,使動力能夠由該出力軸13輸出。為了使該出力軸13能夠具有較佳抗徑向壓力的能力,所設置的二個軸承15、16的距離 不宜過近,則用以組裝該二軸承15、16的支撐座17的長度就不宜過短,造成整個減速機的長度較大。其中,該出力軸13的長期運作下,油封18容易磨損而漏油。 Figure 1 shows the structure of a conventional vertical planetary gear reducer. The reducer comprises a motor 10, a reduction box 11, a coupling 12 and a output shaft 13. The reduction gear box 11 is provided with a planetary gear reduction mechanism (not shown). The coupling 12 is connected to the power output shaft 14 of the reduction gear box 11 and the power output shaft 13 so that power can be output from the power output shaft 13. In order to enable the output shaft 13 to have a better resistance to radial pressure, the distance between the two bearings 15, 16 is set. If it is not too close, the length of the support base 17 for assembling the two bearings 15, 16 should not be too short, resulting in a large length of the entire reducer. Among them, under the long-term operation of the output shaft 13, the oil seal 18 is easily worn and leaks oil.

In the meantime, the second planetary carrier 53 is fixed, and the second ring gear 52 can be used as the second-stage deceleration rotation.
配合圖四及圖六。該外殼60包含設置有一上筒體61、一下杯體62、以及被夾置在該上筒體61與下杯體62之間的該第二行星齒輪組50的第二環齒輪52。憑藉多數個螺釘63將該上筒體61、第二環齒輪52、下杯體62鎖接成一體,且在接合處設有防漏膠,令該外殼60具有防漏功能。 Cooperate with Figure 4 and Figure 6. The outer casing 60 includes a second ring gear 52 provided with an upper cylinder 61, a lower cup 62, and the second planetary gear set 50 interposed between the upper cylinder 61 and the lower cup 62. The upper cylinder 61, the second ring gear 52, and the lower cup 62 are integrally coupled by a plurality of screws 63, and a leakage preventing glue is provided at the joint, so that the outer casing 60 has a leakage preventing function.
該第二行星齒輪架53的下端中央連接一凸軸531,該凸軸531的下半部外徑小於上半部外徑。該外殼60的上筒體61與該第一行星齒輪組 30的第一環齒輪32之間設置有一第一滾錐軸承35。該外殼60的下杯體62與該第二行星齒輪架53下端的凸軸531之間由下而上設置有一第二滾錐軸承55及一滾柱軸承56。該馬達20運轉時,該第二環齒輪52被傳動,而令該外殼60作減速轉動。 A central end of the lower end of the second carrier 53 is connected to a convex shaft 531. The outer diameter of the lower half of the convex shaft 531 is smaller than the outer diameter of the upper half. The upper cylinder 61 of the outer casing 60 and the first planetary gear set A first roller bearing 35 is disposed between the first ring gears 32 of 30. A second roller bearing 55 and a roller bearing 56 are disposed between the lower cup 62 of the outer casing 60 and the convex shaft 531 of the lower end of the second planetary carrier 53 from the bottom. When the motor 20 is in operation, the second ring gear 52 is driven to rotate the outer casing 60.
本發明是藉由該外殼60的轉動來輸出動力。該外殼60的最高和最低點位置,配置了兩個滾錐軸承35、55作為兩個支點,使二支點的間距較長。若該減速機連接攪拌桿70而構成攪拌機時,可承受較大的徑向力和軸向力。故本發明不需加裝長支點支撐座、聯軸器等裝置,可減少零組件,降低成本,並且減少減速機的整體重量與體積。 The present invention outputs power by the rotation of the outer casing 60. The highest and lowest point positions of the outer casing 60 are provided with two roller cone bearings 35, 55 as two fulcrums, so that the distance between the two fulcrums is long. If the reducer is connected to the stirring rod 70 to form a mixer, it can withstand large radial and axial forces. Therefore, the present invention does not need to be equipped with a long fulcrum support seat, a coupling, etc., which can reduce components, reduce costs, and reduce the overall weight and volume of the reducer.
該減速機只有在潤滑油位的上方需要作防塵裝置,以防止粉塵進入。於該外殼60的頂端與該固定法蘭21之間設置有油封22,即可達到防塵作用。油位的下部憑藉前述全密閉式的外殼60來防止漏油。故本發明在不超過正常油位的使用下,完全沒有漏油的可能性。 The reducer only needs to be dustproof above the lubricating oil level to prevent dust from entering. An oil seal 22 is disposed between the top end of the outer casing 60 and the fixed flange 21 to achieve dust prevention. The lower portion of the oil level prevents oil leakage by virtue of the aforementioned fully enclosed outer casing 60. Therefore, the present invention has no possibility of oil leakage under the use of no more than the normal oil level.
請參閱圖七、圖八。該殼體60的下杯體62的下端可連接一攪拌桿70,而構成一攪拌機。該攪拌桿70的頂端設有一水平狀的連接板71。憑藉數個螺釘72將該攪拌桿70的連接板71鎖固在該下杯體62上。其間,該殼體60的下杯體61的底面與該攪拌桿70的連接板71之間壓設一平鍵73。該平鍵73的上部嵌入該下杯體62底面預設的嵌槽621內。該平鍵73的下部嵌入該攪拌桿70的連接板71頂面預設的嵌槽74內。該外殼60是憑藉該平鍵73來帶動該攪拌桿70轉動,進而大幅降低該螺釘72所受到的剪力。 Please refer to Figure 7 and Figure 8. The lower end of the lower cup 62 of the casing 60 can be connected to a stirring rod 70 to constitute a mixer. The top end of the stirring rod 70 is provided with a horizontal connecting plate 71. The connecting plate 71 of the stirring rod 70 is locked to the lower cup 62 by means of a plurality of screws 72. In the meantime, a flat key 73 is pressed between the bottom surface of the lower cup 61 of the casing 60 and the connecting plate 71 of the stirring rod 70. The upper portion of the flat key 73 is embedded in a predetermined recess 621 of the bottom surface of the lower cup 62. The lower portion of the flat key 73 is embedded in the predetermined recess 74 of the top surface of the connecting plate 71 of the stirring rod 70. The outer casing 60 drives the stirring rod 70 to rotate by the flat key 73, thereby greatly reducing the shear force received by the screw 72.
綜上所陳,本發明所提供的殼動式的立式行星齒輪減速機,能夠杜絕漏油,用在對食品、藥品等產品原料的攪拌機上,絕不會因漏油 而污染了原料。本發明作為動力輸出的外殼,其上、下二支點的距離長,轉動時的穩定度高。綜合本發明的無漏油污染,能穩定輸出動力,以及體積小、重量輕、成本低等優點,是為一種創新而又實用的技術。 In summary, the shell-type vertical planetary gear reducer provided by the present invention can prevent oil leakage and is used in a mixer for raw materials such as foods and medicines, and never leaks oil. It pollutes the raw materials. The outer casing of the present invention as a power output has a long distance between the upper and lower fulcrums and a high stability during rotation. The invention has the advantages of no oil leakage pollution, stable output power, small volume, light weight and low cost, and is an innovative and practical technology.
