          洛陽磐龍軸承有限公司---薄壁軸承  Thin wall bearing

          產品介紹

             洛陽磐龍軸承有限公司---薄壁軸承  Thin wall bearing

             薄壁軸承的主要用途   步進電機、醫療器械、辦公器械、檢測儀器、減速機變速裝置、機器人、機械手臂、光學映像器械、旋轉編碼器、**等廣泛領域。

             薄壁套圈軸承精度高、非常安靜以及承載能力很強。這些球軸承有三種設計,并且極端的小、橫截面大多為正方形。在這些系列中,即使是更大的軸直徑和軸承孔,橫截面也保持不變。這些軸承因此稱為等截面。正是這個特性將標準ISO系列中的薄壁套圈軸承與傳統的軸承區別開來。 因此,可以選擇更大的橫截面并使用承載能力更強的軸承而不必改變軸直徑。薄壁套圈軸承可以設計成極度輕而需要很小空間的軸承。

          深溝球軸承、四點接觸球軸承、角接觸球軸承、薄壁套圈軸承可以是深溝球軸承(C)、四點接觸軸承(X) 、角接觸球軸承 (E)。在不同的系列中都提供以上各種設計。系列則取決于橫截面的大小。球與系列匹配。 深溝球軸承可以支持雙向的軸向負載以及徑向負載。 四點接觸軸承可以支持雙向的軸向負載以及徑向負載;因此它們與雙列角接觸球軸承的運行方式相同。 角接觸球軸承可以匹配**數量的球并且其接觸角度為30°。它們支持的徑向負載比深溝球軸承或四點接觸軸承更高,并可以支持源于同一方向的軸向負載。針對特殊需求,角接觸球軸承也可以作為匹配軸承提供。因此,這些組合的剛性和承載能力比單軸承產品要高出很多。

          軸承潤滑的目的

              滾動密封裝置對薄壁軸承的作用軸承的潤滑目的是減少軸承內部摩擦及磨損,防止燒粘、其潤滑效用如下,

          減少摩擦及磨損在構成軸承的套圈、滾動體及保持器的相互接觸部分,防止金屬接觸,減少摩擦、磨損。延長疲勞壽命的滾動疲勞壽命,在旋轉中,滾動接觸面潤滑良好,則延長。相反地,油粘度低,潤滑油膜厚度不好,則縮短。排出摩擦熱、冷卻循環給油法等可以用油排出由摩擦發生的熱,或由外部傳來的熱,冷卻。防止軸承過熱,防止潤滑油自身老化。其他也有防止異物侵入軸承內部,或防止生銹、腐蝕之效果。

              軸承的潤滑方法,分為脂潤滑和油潤滑。為了使軸承很好地發揮機能,首先,要選擇適合使用條件、使用目的的潤滑方法。若只考慮潤滑,油潤滑的潤滑性占優勢。但是,脂潤滑有可以簡化軸承周圍結構的特長,將脂潤滑和油潤滑的利弊比較。             

          保養步驟

          1、先拆下輪子,記得將螺絲收好,掉了就麻煩。

          2、取下軸承,有的輪子的core很緊,軸承很難拆下來,就用六角板手(就是拆螺絲的那一個)用力的給它挖下來,放心,軸承是很不容易壞的!

          3、先用牙刷將培林表面的臟東西刷掉,你不做這步也行,沒差!

          4、有的軸承的側蓋是可拆的,有的則不行,先判斷你是培林是否可拆。怎幺判斷咧?別急!如果在軸承側蓋的邊緣,有一個C形     的環的,就是可拆的,沒有的,就是不可拆的,不過也有例外!

          5、如果是可拆的,就很簡單啦!用一字的精密起子,在C環的缺口,將C環撬起來,再將側蓋取下來,只要拆一邊就好了喔!C環和側蓋要收好,等一下洗完你“可能”想把它們裝回去!

          6、如果是不可拆的,就比較麻煩啦!要用破壞式的方法。 用精密起子伸入側蓋的縫,用力把側蓋撬起來,不要懷疑,就是這樣,不過這側蓋就裝不回去了!嗯,丟掉吧!記得,只要拆一邊就好了,拆兩邊就毀了!

          7、把所有的軸承的一邊側蓋都拆下來,就可以開始洗啰!倒去漬油到碗內,把軸承丟下去攪一攪就可以了。

          安裝和維修程序


          一、軸承安裝和拆卸要謹慎

            不同種類、不同尺寸的薄壁深溝球軸承,其安裝方法和工具也是不盡相同的,其中有機械或者液壓的。這里主要是講解一些通用的基本的一些安裝方法和注意事項。

            不要在滾珠上使勁安裝,這樣會導致滾珠和接觸面局部超載,導致軸承過早的失效。

            第二、不要用堅硬的工具,比如錘子、起子之類的敲打軸承的表面,這樣會讓軸承的外環斷裂或者脆裂。

            二、軸承的清潔

            清潔的使用環境對于軸承是非常重要的。薄壁深溝球軸承環轉動面和滾動元件的表面粗糙精度大概是1/10 μm,這樣光滑的滾珠表面如果受污,其影響是很嚴重的。滾動面之間的潤滑層通常為0.2~1 μm,大于潤滑劑粒徑的顆粒型雜質會受到滾動元件的過度碾壓而在調心滾子軸承鋼中產生局部壓力,最終會導致性材料疲勞。除了這一點,外界環境中的灰塵顆粒大小可達10 μm,也會對調心滾子軸承造成損壞。正因為這樣,干凈整潔的工作環境對于軸承是多么的重要啊。

            三、軸承的工藝檢測

            在使用過程中通過熱干起來感應軸承的工作溫度,如果發現溫度超過規定的限制的話會自動報警,來防止燃軸情況的發生。用高溫經常表示軸承已處于異常情況。高溫也有害于軸承的潤滑劑。有時薄壁深溝球軸承過熱可歸諸于軸承的潤滑劑。若軸承在超過125℃的溫度長期連轉會降低軸承壽命。引起高溫軸承的原因包括:可能是軸承潤滑不足潤滑劑不合格,里面含有雜質,負載過大的時候也可能是軸承內部的間隙不夠油封產生了摩擦      

           

          密封裝置對薄壁軸承的作用

                 在軸承兩端面都有安裝相應的密封裝置,但是很多人并不知道密封裝置有什么作用?下面我們一起來了解一下密封裝置對薄壁軸承有什么作用。

          1、保持軸承內部的潤滑脂(油)在使用中不會流失,保證軸承處于潤滑狀態;

          2、保護軸承外界的塵?;蛴泻怏w不會進入軸承內腔,以防對軸承造成損傷。

          密封圈的密封結構是多種多樣的,因此密封效果也是不同的。密封圈與轉軸之間有間隙的,稱非接觸式密封,間隙越小,密封效果越好,但允許軸的轉速越??;相反則反之。密封圈與轉軸之間無間隙的,稱接觸式密封,密封圈接觸唇的接觸面積越大,密封效果越好,但允許軸的轉速越小,相反則反之。密封技術主要研究內容,就是研究開發應用于不同工況下的相應密封裝置,以及該密封圈材料與相應潤滑脂的共融性等。

          Luoyang Panlong Bearing Co. Ltd. - thin wall bearing

          Thin wall bearings are the main purpose of the stepper motor, medical equipment, office equipment, testing equipment, gear transmission, robotics, robot arm, optical image equipment, rotary encoder, military and other fields.

          High precision thin ring bearing, very quiet and strong bearing ability. These ball bearings have three designs, and are extremely small, the cross section is mostly square. In these series, the cross section is also kept constant even though the larger shaft diameter and bearing bore. These bearings are therefore called uniform. It is this feature will be the standard ISO series

          The difference between the bearing and the traditional open thin-walled bearing rings. Therefore, we can choose a larger cross section and use more bearing capacity of the bearing without changing the shaft diameter. Thin section bearings can be designed into the extreme light and bearing a very small space.

          Deep groove ball bearing, four point contact ball bearing, angular contact ball bearings

          Thin section bearings can be deep groove ball bearings (C), four point contact ball bearings (X), angular contact ball bearings (E). All kinds of designs are available in different series. The series is determined by the size of the cross section. Ball and series matching. Deep groove ball bearing can support axial load and radial load bidirectional. The four point contact bearing can support both the axial load and the radial load, so they are the same as the double row angular contact ball bearing. Angular contact ball bearings can match the optimal number of balls and the contact angle is 30 degrees. They support radial load is much higher than that of deep groove ball bearing or four point contact ball bearing, and can support the source in the same direction of the axial load. For special needs, angular contact ball bearings can also be used as matching bearings. Therefore, the rigidity and bearing capacity of these combinations are higher than those of single bearing products.

          Purpose of bearing lubrication

          Rolling sealing device for the role of thin walled bearings bearing lubrication is to reduce the internal friction and wear and tear, to prevent the burn, the lubrication is as follows,

          Reduce friction and wear in the bearing rings, rolling bodies and the holder of the interaction, to prevent metal to metal contact, reducing friction, wear and tear. To prolong the fatigue life of the rolling fatigue life, in the rotation, rolling contact surface lubrication is good, then extended. On the contrary, the oil viscosity is low, and the oil film thickness is not good, then the. Discharge of heat, cooling water, etc., can be used for oil discharge by the friction heat, or by the external heat, cooling. To prevent the bearing from overheating, to prevent the lubricating oil itself aging. Other also prevent foreign body into the bearing internal, or prevent the effect of rust, corrosion.

          Bearing lubrication method, divided into grease and oil lubrication. In order to make the bearing a good function, first of all, we should choose the suitable conditions, the use of the purpose of lubrication method. If only considering the lubrication, the lubrication oil lubrication of the advantages. However, the grease lubrication has the advantages of simplifying the structure of the bearing, and comparing the advantages and disadvantages of grease and oil lubrication. Maintenance procedure

          1, first remove the wheel, remember to put the screws on, out of trouble.

          2, take the bearing, some of the wheels of the core is very tight, the bearing is difficult to remove, with the six corner plate hand (that is, the screw is the one) to dig down hard, rest assured that the bearing is not easy to bad!

          3, first use a toothbrush to brush off the bearing surface dirt, you do not do this step, not bad!

          4, some bearing side cover is detachable, some are not, you are to judge whether Palin. How to judge? Don't worry! If the edge of the cover on the side of the bearing, a C-shaped ring is removable, no is not detachable, but there are exceptions.

          5, if it is detachable, is very simple! With a precision screwdriver, the gap in the C ring, C ring pry up, and then the side cover off, as long as the split side is good oh! C ring and side cover to close, and so on, and so you may want to put them back!

          6, if it is not detachable, more trouble! To use the destructive method. Precision screwdriver inserted into the cover side seam, forced the side cover pry up, no doubt, is such, but the side cover will not hold back the! Well, throw it away! Remember, as long as the demolition side is good, and the demolition on both sides destroyed!

          7, the side all bearing cover are removed, you can start washing! Pour the oil into the bowl, and the bearing can be thrown down.

          Installation and maintenance procedures

          One, bearing installation and removal must be cautious

          Different kinds and different sizes of the thin-walled deep groove ball bearings, the installation methods and tools is not the same, including mechanical or hydraulic. Here mainly to explain some of the basic of some of the basic installation methods and precautions.

          Do not install on the ball hard, this will lead to the ball and the contact surface overload, resulting in premature failure of bearings.

          Second, do not use hard tools, such as hammer, screwdriver, like the beat the bearing surface, this will let the outer bearing ring fracture or brittle fracture.

          Two, bearing the clean

          Clean use of the environment for bearings is very important. Thin-walled deep groove ball bearing ring plane of rotation and rolling rough surface accuracy of the element is about 1 / 10 m, so smooth ball surface if contaminated, its influence is very serious. Rolling surface between the lubricating layer usually is 0.2 ~ m greater than lubricant particle size type impurities will be subject to excessive rolling rolling element and produce local pressure in the spherical roller bearing steel, will eventually lead to material fatigue. In addition to this, the external environment of dust particle size is 10 m, it will cause damage to the spherical roller bearing. Just because of this, clean and clean working environment for the bearing is how important ah.

          Three, bearing process detection

          The operating temperature of the bearing is used in the process of heating, and if the temperature exceeds the specified limit, it will automatically alarm, to prevent the occurrence of the burning shaft. High temperature often said that the bearing has been abnormal. High temperature is also harmful to the bearing lubricant. Sometimes the thin-walled deep groove ball bearing overheating can be attributed to the bearing lubricant. If the bearing in the temperature of more than 125 degrees for a long time even transfer to reduce bearing life. Caused by high temperature bearing of the reasons include: may be the lubrication of bearing lubrication is not qualified, which contains impurities, the load is too large may also be bearing internal clearance is not enough oil seal produced friction

          The effect of sealing device on thin wall bearing

          In the bearing two end face have to install the corresponding sealing device, but a lot of people do not know what role? Here we come together to understand how the sealing device for thin walled bearing.

          1, to maintain the internal lubrication grease (oil) in the use of the will not lose, to ensure that the bearings in the lubrication state;

          2, the protection of bearing outside dust or harmful gas will not enter the bearing chamber, in case of damage to bearing.

          Seal ring seal structure is a variety of, so the effect is different. There is a gap between the sealing ring and the shaft, said non contact seal, the smaller the gap, the better the sealing effect, but the smaller the speed of the shaft. Seal ring with the gap between the shaft, said contact seal, sealing ring contact area of the contact area, the better the sealing effect, but the smaller the speed of the shaft, the opposite is the opposite. The main research content of the sealing technology is the research and development of the corresponding sealing device for different working conditions, as well as the sealing ring material and the corresponding lubricating grease.
