The Advantage of Powder Metallurgy Process
1. Cost effective
The final products can be compacted with powder metallurgy method ,and no need or can shorten the processing of machine .It can save material greatly and reduce the production cost .
2. Complex shapes
Powder metallurgy allows to obtain complex shapes directly from the compacting tooling ,without any machining operation ,like teeth ,splines ,profiles ,frontal geometries etc.
3. High precision
Achievable tolerances in the perpendicular direction of compacting are typically IT 8-9 as sintered,improvable up to IT 5-7 after sizing .Additional machining operations can improve the precision .
4. Self-lubrication
The interconnected porosity of the material can be filled with oils ,obtaining then a self-lubricating bearing :the oil provides constant lubrication between bearing and shaft ,and the system does not need any additional external lubricant .
5. Green technology
The manufacturing process of sintered components is certified as ecological ,because the material waste is very low ,the product is recyclable ,and the energy efficiency is good because the material is not molten.

如何更換軸承
如果您想為特定應用選擇軸承，您應該了解一些基本知識。本文將概述滾珠軸承、角接觸軸承和滑動接觸軸承。您可以根據軸承的材料特性和預緊力，根據應用選擇合適的軸承。如果您不確定如何選擇軸承，可以嘗試進行一些實驗。下一步是了解 Z 軸，即軸承運動的軸線。
Z軸
更換 Z 軸軸承時，您需要了解以下幾點。首先，確保軸承安裝正確。然後，檢查每個軸承的張力和旋轉情況。為了確保兩個軸承的張力相同，您需要將 Z 軸核心零件彎曲到所需角度。這樣可以保持 Z 軸垂直於工作檯面。具體操作方法是：先將 Z 軸軸承從軸承座中取出，然後將其插入 Z 軸馬達安裝板。接下來，將帶有法蘭的軸承插入 Z 軸馬達安裝板，並用兩顆 M5x8mm 圓頭螺絲固定。
確保軸承座和 Z 軸聯軸器零件齊平且間距相等。這兩個部件之間的間距非常重要，因為間距過大會導致絲槓過緊。除了與尼龍鎖緊螺帽嚙合的螺絲外，其他螺絲都應該非常鬆脫。安裝軸承後，下一步是啟動 Z 軸。完成此步驟後，您就可以使用步進馬達來移動它了。
角接觸
滾珠軸承採用角接觸設計，導致軸承內外圈之間有一定角度。軸向負荷沿著軸承的同一方向傳遞，而徑向負荷則沿著曲線路徑傳遞，這會使內外圈在軸向上產生分離。為了最大限度地減少這種摩擦效應，角接觸軸承的內外圈設計成相同的接觸角。接觸角的選擇必須與軸向載重和徑向載重的相對比例相符。通常，較大的接觸角可以承受更高的軸向負荷，同時降低徑向負荷。
球軸承是最常見的角接觸軸承類型。角接觸球軸承應用廣泛，但主要用於工具機主軸。這類軸承適用於高速、高精度旋轉。其徑向承載能力與角接觸角成正比，因此接觸角越大，轉速越高。角接觸球軸承有單列和雙列兩種結構。
角接觸球軸承是承受軸向負荷和複雜形狀應用的理想選擇。這類軸承的內外圈均設有滾道，並沿軸向相互滑動。其軸向承載能力隨接觸角α的增大而提高。角接觸球軸承可承受高達其初始重量5倍的負荷！對於軸承新手，網上有很多相關資源可供參考。
儘管結構複雜，角接觸球軸承用途廣泛，可應用於多種領域。其獨特的角接觸特性使其能夠承受適中的徑向和軸向負荷。與其他一些軸承不同，角接觸球軸承可以串聯安裝以減少摩擦。此外，它們還具有預緊機構，可在軸承使用過程中消除過大的間隙。
角接觸球軸承採用不同的潤滑劑和保持架材質。角接觸球軸承的標準保持架如表1所示。有些保持架由機械加工合成樹脂製成，有些則由模壓聚醯胺製成。這些保持架材料的使用旨在進一步提高軸承的軸向承載能力。此外，角接觸球軸承能夠承受高速和徑向負荷。與徑向接觸球軸承相比，角接觸球軸承具有更高的靈活性。
滾珠軸承
滾珠軸承是由兩個獨立的內圈和外圈組成的圓形結構。較小的內圈安裝在軸上。內圈外徑上有一個溝槽，作為滾珠的運行軌道。內圈和外圈的表面都經過精密加工，具有極高的精度和公差。外圈是包含滾動體的圓形結構。這些滾動體可以採用多種形式。內圈和外圈通常由鋼或陶瓷製成。
氮化矽陶瓷球具有良好的耐腐蝕性和輕質特性，但比氧化鋁球更昂貴。它們還具有絕緣性和自潤滑性。氮化矽也適用於高溫環境。然而，這種材料的缺點是磨損快，容易開裂和破碎，軸承鋼和玻璃也是如此。它的耐熱性也比氧化鋁差，因此對於需要承受極高溫的應用，最好選擇氮化鋁或陶瓷球軸承。
另一種滾珠軸承是推力軸承。它採用特殊設計，可以承受軸向和徑向的力道。由於其滾道並排排列，因此也稱為雙向軸承。軸向滾珠軸承也採用並排設計，當負荷通過車輪傳遞時，會使用軸向滾珠。然而，它們的軸向支撐性能較差，在承受較大的徑向負荷時容易分離。
滾珠軸承的基本原理是減少摩擦。減少摩擦可以提高能量傳遞效率，減少磨損，並延長機器的使用壽命。隨著當今技術的進步，滾珠軸承的性能比以往任何時候都更加出色。從鐵、鋼到塑料，軸承所用材料的性能都得到了顯著提升。軸承還可以整合電磁場。因此，為您的機器選擇合適的軸承至關重要。
滾珠軸承的使用壽命取決於多種因素，包括運轉速度、潤滑和溫度。一個轉速為百萬轉/分的滾珠軸承可以承受100萬到500萬次的旋轉。只要其接觸面積盡可能小，它至少可以承受100萬次的旋轉。然而，滾珠軸承的平均壽命取決於其應用和運作條件。幸運的是，大多數軸承在出現疲勞跡象之前可以承受100萬次或更多次的旋轉。
滑動接觸軸承
滑動接觸軸承的基本原理是兩個表面相互接觸滑動。這種軸承最適用於表面由不同材料製成的情況。例如，鋼軸不應在青銅襯裡的孔中運行，反之亦然。相反，其中一種材料應該比另一種材料更硬，因為磨損會集中在較硬的區域。此外，磨粒往往會擠入較軟的表面，導致該部分磨損出溝槽。
滑動軸承摩擦係數低，常用於低速應用。與滾珠軸承和滾子軸承不同，滑動軸承需要在接觸面的兩側進行潤滑，以最大程度地減少磨損。滑動軸承通常由陶瓷、黃銅和聚合物製成。由於摩擦係數較低，其精度不如滾動軸承。
滑動軸承也稱為滑動軸承或套筒軸承。其兩個表面之間存在滑動運動，潤滑可以減少這種滑動。這種軸承常用於旋轉應用和導向機構。除了提供滑動作用外，滑動軸承還具有自潤滑性和高承載能力。它們通常分為兩種類型：滑動軸承和推力軸承。
滑動接觸式直線軸承系統由一個移動結構（稱為滑塊）和兩個元件滑動的表面組成。軸承和軸頸滑動的表面稱為導軌。軸承孔的幾何形狀複雜，通常在中心線上使用最小油膜厚度 h0。滑動接觸式軸承也可以安裝在軸承座內。
由於這些軸承具有多孔性，它們可以吸收15至30%的潤滑油。這種材料常用於汽車和工具機。許多非金屬材料也被用作軸承。例如橡膠，它具有優異的減震性和可嵌入性。雖然橡膠強度和導熱性較差，但它常用於深井泵和離心泵。這種材質具有很高的衝擊強度，但剛性不如鋼。
