Description

引擎之油潤構造Engine oily structure

本發明涉及一種機車引擎變速箱的結構,尤其是一種引擎之油潤構造。The invention relates to a structure of a locomotive engine gearbox, in particular to a fuel-tight structure of an engine.

目前現有技術的引擎變速箱之油潤構造,係設有箱體、齒輪組、供油口、儲油槽及吸油口;齒輪組設於箱體內,供油口設於齒輪組之心軸、而能以飛濺的方式持續供油至齒輪組進行潤滑;儲油槽設於箱體內部空間的底部並藉由油路將油運送至供油口;吸油口設於箱體並能將箱體內儲油槽蓄積的潤滑油運至供油口。At present, the oil-running structure of the prior art engine gearbox is provided with a box body, a gear set, a fuel supply port, an oil storage tank and an oil suction port; the gear set is arranged in the box body, and the oil supply port is arranged on the spindle of the gear set, and The oil can be continuously supplied to the gear set for lubrication by splashing; the oil storage tank is arranged at the bottom of the inner space of the tank and transports the oil to the oil supply port through the oil passage; the oil suction port is arranged in the tank body and can be used for the oil storage tank in the tank body The accumulated lubricant is transported to the fuel supply port.

現有技術的引擎變速箱之油潤構造,因為供油口設於齒輪組之心軸,所以當心軸轉動時,潤滑油能夠從供油口旋轉飛濺而出,並飛濺至引擎變速箱內的其他齒輪,達到潤滑齒輪組的目的。雖然能夠對齒輪組整體且大範圍地飛濺,但是飛濺的方式對齒輪的潤滑並不是很穩定,有時未飛賤到,即無油可供潤滑,因此,單以飛濺方式潤滑的油量不足,潤滑效果不佳,容易造成齒輪磨損。In the oil-straining structure of the prior art engine gearbox, since the oil supply port is provided on the spindle of the gear set, when the mandrel rotates, the lubricating oil can be spouted from the oil supply port and splashed to the other in the engine gearbox. Gears achieve the purpose of lubricating the gear set. Although the gear set can be splashed as a whole and in a wide range, the way of splashing is not very stable to the lubrication of the gear, and sometimes it is not flying, that is, no oil is available for lubrication. Therefore, the amount of oil that is lubricated by splash alone is insufficient. The lubrication effect is not good and it is easy to cause gear wear.

另有其他型式的引擎變速箱之油潤構造,請參考日本專利JP4035226及JP2008-144900號專利案,其係將齒輪組設於箱體靠近底部的位置,並讓齒輪組的齒浸潤於儲油槽的油內,雖然能夠直接對齒輪組潤滑,但其僅對單一齒輪直接潤滑,並無設置讓潤滑油飛濺的結構、讓潤滑油對齒輪組整體且大範圍地飛濺。而且,由於潤滑油有一定的黏稠度且齒輪組的齒浸潤於油的深度過深,所以儲油槽的油會導致齒輪旋轉時阻抗過大,油容易變熱且變質,實有改善的必要。For other types of engine gear transmissions, please refer to Japanese Patent No. JP4035226 and JP2008-144900. The gear set is placed near the bottom of the box, and the gears of the gear set are immersed in the oil reservoir. In the oil, although the gear set can be directly lubricated, it is directly lubricated only for a single gear, and there is no structure for splashing the lubricating oil, and the lubricating oil is splashed over the entire gear train. Moreover, since the lubricating oil has a certain viscosity and the teeth of the gear set are infiltrated into the depth of the oil too much, the oil in the oil reservoir causes the impedance to be excessive when the gear rotates, and the oil is easily heated and deteriorated, which is necessary for improvement.

為解決現有技術的引擎變速箱之油潤構造,有關於無法同時達到直接浸潤齒輪、以及讓潤滑油對齒輪組整體且大範圍地飛濺的不足與限制。本發明的目的在於提供一種引擎之油潤構造,其設置第一儲油槽及第二儲油槽,第一儲油槽的油運送至供油口而以飛濺或滴落的方式來潤滑齒輪組,亦或將油直接輸出第二儲油槽內,第二儲油槽內的油直接浸潤齒輪組,藉此達到同時直接浸潤齒輪組、以及讓潤滑油對齒輪組整體且大範圍地飛濺的目的。In order to solve the oil-oil structure of the prior art engine gearbox, there is a deficiency and limitation that the direct wetting gear cannot be simultaneously achieved, and the lubricating oil is splashed on the gear train as a whole and in a wide range. An object of the present invention is to provide a fuel-tight structure of an engine, which is provided with a first oil storage tank and a second oil storage tank, and the oil of the first oil storage tank is transported to the oil supply port to lubricate the gear set by splashing or dripping. Or the oil is directly outputted into the second oil storage tank, and the oil in the second oil storage tank directly infiltrates the gear set, thereby achieving the purpose of simultaneously directly wetting the gear set and allowing the lubricating oil to splash on the gear unit as a whole and in a wide range.

其中,本發明的該齒輪組20中的至少一個齒輪定義為浸潤齒輪(也就是浸潤齒輪包括一個以上的齒輪),浸潤齒輪的最下方的齒的齒峰低於第二儲油槽40的流通端42,而在本發明第一較佳實施例中的浸潤齒輪是為第二齒輪24。Wherein at least one gear of the gear set 20 of the present invention is defined as a wetting gear (that is, the wetting gear includes more than one gear), and the tooth peak of the lowermost tooth of the wetting gear is lower than the circulating end of the second oil reservoir 40 42. The wetting gear in the first preferred embodiment of the present invention is the second gear 24.

浸潤齒輪可以是第一齒輪22、第二齒輪24或第三齒輪26,本發明對於哪一個齒輪當作浸潤齒輪不作特定的限制,只要齒輪組20的至少一個齒輪浸潤於第二儲油槽40內即可。浸潤齒輪亦可以包括兩個齒輪,例如第一齒輪22及第二齒輪24皆浸潤於第二儲油槽40內,本發明亦不作限制。The wetting gear may be the first gear 22, the second gear 24 or the third gear 26. The present invention does not specifically limit which gear is used as the wetting gear, as long as at least one gear of the gear set 20 is infiltrated into the second oil reservoir 40. Just fine. The infiltration gear may also include two gears. For example, the first gear 22 and the second gear 24 are all infiltrated in the second oil reservoir 40, and the invention is not limited thereto.

另外,第二儲油槽40的流通端42不高於浸潤齒輪的齒輪軸,也就是說,當浸潤齒輪為第二齒輪24時,浸潤齒輪的齒輪軸此時為第二軸23;當浸潤齒輪為第一齒輪22時,浸潤齒輪的齒輪軸此時為第一軸21。In addition, the flow end 42 of the second oil storage tank 40 is not higher than the gear shaft of the wetting gear, that is, when the wetting gear is the second gear 24, the gear shaft of the wetting gear is now the second shaft 23; when the wetting gear When it is the first gear 22, the gear shaft of the wetting gear is now the first shaft 21.

該供油口50位於該齒輪組20的至少一個齒輪軸上,也就是該供油口50位於該齒輪組20的第一軸21或第二軸23或第三軸25,如圖5所示,較佳地,該供油口50位於該第三軸25;當第三軸25轉動時,從供油口50流出的潤滑油利用離心力而飛濺潤滑齒輪組20,或蓄積於該第二儲油槽40,其餘的潤滑油再回流至第一儲油槽32;該供油口50亦可位於該第一軸21或第二軸23也可以達到相同的功效,本發明對於供油口50的位置不作特定的限制。The oil supply port 50 is located on at least one gear shaft of the gear set 20, that is, the oil supply port 50 is located at the first shaft 21 or the second shaft 23 or the third shaft 25 of the gear set 20, as shown in FIG. Preferably, the oil supply port 50 is located on the third shaft 25; when the third shaft 25 rotates, the lubricating oil flowing out of the oil supply port 50 splashes and lubricates the gear set 20 by centrifugal force, or accumulates in the second storage The oil tank 40, the remaining lubricating oil is returned to the first oil storage tank 32; the oil supply port 50 can also be located at the first shaft 21 or the second shaft 23, and the same effect can be achieved. The position of the oil supply port 50 of the present invention. No specific restrictions are imposed.

如圖1及圖2所示,該油泵60包括一本體及一與該本體連接的油路,該油泵60經由該油路分別連通該第一儲油槽32及該供油口50。As shown in FIG. 1 and FIG. 2 , the oil pump 60 includes a body and an oil passage connected to the body. The oil pump 60 communicates with the first oil storage tank 32 and the oil supply port 50 via the oil passage.

如圖2、圖6及圖7所示,本發明的第一實施例於使用時(虛線箭頭代表油的流通路徑示意)係將潤滑油以飛濺的方式從供油口50持續供應於齒輪組20,使齒輪組20能夠持續被潤滑;而多餘的潤滑油則會蓄積於第一儲油槽32及第二儲油槽40,並於第一儲油槽32的潤滑油的液面形成一第一油面S1,於第二儲油槽40的潤滑油的液面形成一第二油面S2;其中,第二儲油槽40的內壁底面的高度高於第一油面S1。As shown in FIG. 2, FIG. 6, and FIG. 7, the first embodiment of the present invention, when used (the dotted arrow indicates the flow path of the oil), continuously supplies the lubricating oil from the oil supply port 50 to the gear set in a splash manner. 20, the gear set 20 can be continuously lubricated; and the excess lubricating oil is accumulated in the first oil storage tank 32 and the second oil storage tank 40, and a first oil is formed on the liquid surface of the lubricating oil of the first oil storage tank 32. The surface S1 forms a second oil level S2 on the liquid surface of the lubricating oil of the second oil storage tank 40. The height of the bottom surface of the inner wall of the second oil storage tank 40 is higher than the first oil level S1.

由於第二齒輪24大齒盤部241最下方的齒2411低於第二儲油槽40的流通端42,且由於第二儲油槽40的第二油面S2大約與第二儲油槽40的流通端42位於同一平面,因此,第二齒輪24最下方的齒2411會低於第二油面S2並浸潤於第二儲油槽40的潤滑油內。當第二齒輪24持續轉動時,能夠不斷地將第二儲油槽40的潤滑油帶上,並使潤滑油進一步均勻地飛濺至齒輪組20;進一步較佳地,如圖8所示,第二齒輪24大齒盤部241最下方的齒2411的齒峰24111與第二油面S2之間的距離L為第二齒輪24大齒盤部241的齒高H的0.5至2倍。較佳地,齒峰24111與第二油面S2之間的距離L為齒高H的1倍。由於第二齒輪24最下方的齒2411浸潤於油的深度變淺,所以第二齒輪24旋轉時受到油阻的阻抗小,油不易變質;且由於浸潤於油的深度淺,第二齒輪24旋轉時易於撥動油而使油飛濺,並且能夠達到雙重飛濺的效果。Since the lowermost tooth 2411 of the large gear portion 241 of the second gear 24 is lower than the flow end 42 of the second oil reservoir 40, and because the second oil level S2 of the second oil reservoir 40 is approximately the circulation end with the second oil reservoir 40 The 42 is located on the same plane. Therefore, the lowermost tooth 2411 of the second gear 24 is lower than the second oil level S2 and is infiltrated into the lubricating oil of the second oil reservoir 40. When the second gear 24 continues to rotate, the lubricating oil of the second oil storage tank 40 can be continuously brought on, and the lubricating oil is further uniformly splashed to the gear set 20; further preferably, as shown in FIG. The distance L between the tooth peak 24111 of the lowermost tooth 2411 of the gear 24 large toothed portion 241 and the second oil surface S2 is 0.5 to 2 times the tooth height H of the large gear portion 241 of the second gear 24 . Preferably, the distance L between the tooth peak 24111 and the second oil level S2 is 1 times the tooth height H. Since the lowermost tooth 2411 of the second gear 24 is wetted to the depth of the oil, the impedance of the second gear 24 is less affected by the oil resistance, the oil is not easily deteriorated, and the second gear 24 is rotated due to the shallow depth of the oil. It is easy to move the oil to splash the oil and achieve the double splash effect.

接下來,當第二儲油槽40的油蓄滿時,多餘的油經由流通端42流至第一儲油槽32。吸油口321位於第一儲油槽32的底部,藉由油泵60通過泵送依序經過左殼體11內部形成的油路、外蓋13內部形成的油路、第三軸25而送至供油口50、能將潤滑齒輪組20後的油運至第一儲油槽32。而油泵60連接吸油口321及供油口50,油泵60的作用在於將第一儲油槽32的油運送至供油口50,並再一次從供油口50飛濺而出,藉此形成一個循環。Next, when the oil of the second oil storage tank 40 is full, excess oil flows to the first oil storage tank 32 via the circulation end 42. The oil suction port 321 is located at the bottom of the first oil storage tank 32, and is pumped to the oil supply by the oil pump 60 through the oil passage formed inside the left casing 11, the oil passage formed inside the outer cover 13, and the third shaft 25. The port 50 can transport the oil after lubricating the gear set 20 to the first oil storage tank 32. The oil pump 60 is connected to the oil suction port 321 and the oil supply port 50. The oil pump 60 functions to transport the oil of the first oil storage tank 32 to the oil supply port 50, and once again splashes out from the oil supply port 50, thereby forming a cycle. .
