Description
本發明係關於一種軸承之壽命測試機，特別是一種利用襯套之軸承壽命測試機。The present invention relates to a bearing life testing machine, and more particularly to a bearing life testing machine using a bushing.
軸承(bearing)是機構元件中支撐旋轉軸很重要的零件，軸承的好壞直接影響機械性能，因此軸承的設計對於轉動機構的壽命與穩定性成了重要的關鍵。Bearing is a very important part of the mechanical component supporting the rotating shaft. The bearing quality directly affects the mechanical properties. Therefore, the design of the bearing becomes an important key to the life and stability of the rotating mechanism.
目前習用之軸承大致上可分為二種：滾珠軸承及油潤式軸承。該滾珠軸承內設置複數個滾珠以減少軸承內部與旋轉軸間之摩擦，且配合特殊潤滑油產生潤滑作用，可減少旋轉軸轉動時之摩擦力並使旋轉軸穩定，此類軸承雖有高負荷與高穩定性的優點，但轉速受到限制，在裝配上也會有精度上的問題，較難裝配，此外，還有震動的問題，並價格昂貴。在一些需要更高速運轉的機械元件，逐漸被該油潤式軸承所取代。At present, the conventional bearings can be roughly divided into two types: ball bearings and oil-lubricated bearings. The ball bearing is provided with a plurality of balls to reduce the friction between the inside of the bearing and the rotating shaft, and the lubricating oil is combined with the special lubricating oil to reduce the frictional force when the rotating shaft rotates and stabilize the rotating shaft. Although such bearings have high load With the advantages of high stability, but the speed is limited, there will be problems in accuracy in assembly, it is difficult to assemble, in addition, there are vibration problems, and it is expensive. In some mechanical components that require higher speed operation, they are gradually replaced by the oil-lubricated bearings.
該油潤式軸承分為動壓軸承及靜壓軸承。該動壓軸承係於軸承上方作一小孔將潤滑油注入，當旋轉軸轉動時帶動潤滑油使旋轉軸潤滑，有些設計甚至會在軸承內側刻畫溝紋使得旋轉軸旋轉時更加穩定。該靜壓軸承屬於比較高級的軸承，具有極高精度的特性，靜壓軸承在旋轉軸與軸承間形成的潤滑油膜或潤滑空氣薄膜比其他形式軸承厚，具有緩和旋轉軸與軸承面形狀誤差，發揮並實現平滑的運轉效果，將此運轉效果稱為潤滑薄膜的均化效果。The oil-lubricated bearing is divided into a dynamic pressure bearing and a hydrostatic bearing. The dynamic pressure bearing is made of a small hole above the bearing to inject the lubricating oil. When the rotating shaft rotates, the lubricating oil is driven to lubricate the rotating shaft. Some designs even describe the groove on the inner side of the bearing to make the rotating shaft rotate more stably. The hydrostatic bearing belongs to a relatively advanced bearing and has extremely high precision characteristics. The lubricating oil film or the lubricating air film formed between the rotating shaft and the bearing of the hydrostatic bearing is thicker than other types of bearings, and has the shape error of the rotating shaft and the bearing surface. The smooth running effect is exerted and achieved, and this operation effect is called the homogenization effect of the lubricating film.
然而由於現今之電子產品越來越輕薄短小，因此所配用之軸承之尺寸也日益減小。因而如何測試細小軸承之壽命便成為一項重要之課題。However, as today's electronic products are becoming lighter and thinner, the size of the bearings used is also decreasing. Therefore, how to test the life of a small bearing becomes an important issue.
因此，有必要提供一創新且具進步性之軸承之壽命測試機，以解決上述問題。Therefore, it is necessary to provide an innovative and progressive bearing life testing machine to solve the above problems.
本發明係提供一種軸承之壽命測試機，其包括一待測軸承、至少一支撐軸承、一固定鞍座、至少一襯套、一荷重及一中心轉軸。該待測軸承係緊配於該至少一支撐軸承內。該至少一支撐軸承係緊配該固定鞍座內。該至少一襯套位於該固定鞍座之側邊，該襯套具有一中心軸孔，該中心軸孔係與該待測軸承同軸心。該荷重係施加於該固定鞍座上。該中心轉軸係穿入該至少一襯套之中心軸孔及該待測軸承。藉此，該中心轉軸轉動後，當監測之一溫度超過一預設值時即判斷該待測軸承達到其壽命。The invention provides a life testing machine for a bearing, comprising a bearing to be tested, at least one supporting bearing, a fixing saddle, at least one bushing, a load and a central rotating shaft.

Next, referring to FIG. 2 , the oscillator 33 is disposed on the second sidewall 412 of the cavity 41 , and the air suction hose 23 is inserted into the air vent 4141 of the fourth sidewall 414 of the cavity 41 .
接著，將該中心轉軸34裝設於該轉軸連結器30上後，蓋上該箱體14之拉門13。Next, after the center shaft 34 is attached to the shaft coupling 30, the sliding door 13 of the box 14 is covered.
接著，啟動該電腦主機15及該氣液壓控制箱12。藉由啟動該第二伺服馬達27以帶動該滑座組35及該測試模組25向右移動，使得該中心轉軸34穿過該第一側壁411之第一貫穿孔4112，而穿入該襯套40之中心軸孔401及該待測軸承37。藉由啟動該抽氣泵浦20將該測試模組25內空氣抽出至1*10-3 Pa。接著，藉由啟動第一伺服馬達26，該第一伺服馬達26經由該皮帶輪組28帶動該轉軸連結器30及該中心轉軸34(該中心轉軸34之轉速最高可達15000rpm)。接著，藉由啟動該抽水泵浦22將水注入該荷重水箱19內(最大荷重約為3公斤)。最後，啟動該振盪器33用以提供一震動頻率。此時即可開始測試，並且記錄以下數據：該潤滑油溫度、該中心轉軸34之轉速、該荷重水箱19之荷重及該震動頻率。Next, the computer main unit 15 and the gas hydraulic control box 12 are activated. The lining is driven by the second servo motor 27 to move the slider set 35 and the test module 25 to the right, so that the central rotating shaft 34 passes through the first through hole 4112 of the first sidewall 411 and penetrates the lining. The central shaft hole 401 of the sleeve 40 and the bearing 37 to be tested. The air in the test module 25 is drawn to 1*10 -3 Pa by activating the pumping pump 20. Then, by activating the first servo motor 26, the first servo motor 26 drives the spindle coupling 30 and the center shaft 34 via the pulley set 28 (the center shaft 34 has a rotational speed of up to 15,000 rpm). Next, water is injected into the load water tank 19 by activating the pump 22 (maximum load is about 3 kg). Finally, the oscillator 33 is activated to provide a vibration frequency. At this point, the test can be started and the following data recorded: the temperature of the lubricating oil, the rotational speed of the central shaft 34, the load of the load water tank 19, and the vibration frequency.
在正常情況下，該中心轉軸34與該待測軸承37之內側壁及該襯套40之內側壁間具有適當間隙(約為數μm)，因此該中心轉軸34可以順利地轉動。然而，當該待測軸承37損壞時，該中心轉軸34會接觸到該待測軸承37之內側壁或該襯套40之內側壁，此時由於高速摩擦作用，該待測軸承37、該潤滑油及該襯套40之溫度會急速上升。因此，當該等溫度探針24所監測之潤滑油之溫度超過一預設值時即判斷該待測軸承37達到其壽命。Under normal circumstances, the center shaft 34 has a proper gap (about several μm) between the inner side wall of the bearing 37 to be tested and the inner side wall of the bushing 40, so that the center shaft 34 can be smoothly rotated. However, when the bearing 37 to be tested is damaged, the center shaft 34 will contact the inner side wall of the bearing 37 to be tested or the inner side wall of the bushing 40. At this time, the bearing to be tested 37, the lubrication due to high-speed friction. The temperature of the oil and the bushing 40 will rise rapidly. Therefore, when the temperature of the lubricating oil monitored by the temperature probes 24 exceeds a predetermined value, it is judged that the bearing 37 to be tested reaches its life.
在本實施例中，該溫度感測器及該等溫度探針24係用以感測該潤滑油之溫度。然而可以理解的是，該溫度感測器及該等溫度探針24也可以連接至該襯套40或該固定鞍座39，以感測該襯套40或該固定鞍座39之溫度，亦即所監測之溫度係為該襯套40或該固定鞍座39之溫度。In this embodiment, the temperature sensor and the temperature probes 24 are used to sense the temperature of the lubricating oil. However, it can be understood that the temperature sensor and the temperature probes 24 can also be connected to the bushing 40 or the fixed saddle 39 to sense the temperature of the bushing 40 or the fixed saddle 39. That is, the temperature monitored is the temperature of the bushing 40 or the fixed saddle 39.
本發明之該軸承之壽命測試機1之優點為構件簡單，整體造價低；而且如要測試不同之該待測軸承37的話，只要更換不同大小之襯套40及該支撐軸承38即可，其操作簡單，可減少測試成本。The life testing machine 1 of the bearing of the present invention has the advantages of simple components and low overall cost; and if different bearing 37 to be tested is to be tested, only the bushing 40 of different sizes and the supporting bearing 38 can be replaced. Simple to operate, reducing test costs.
