Abstract
Description
一種軸承成型方法，尤指一種依照軸承局部所需之結構特性分以局部分段加壓燒結成型的軸承成型方法。
The invention relates to a bearing forming method, in particular to a bearing forming method which is formed by partial sectional pressure sintering in accordance with structural characteristics required for a part of a bearing.
軸承係為一種可提供馬達轉子心軸樞設其中，進而可減少風扇軸座磨損並延長風扇壽命的結構，在已知的軸承結構當中，有一種具有自潤效果的含油軸承，已普遍的裝設在小型馬達之軸套中供心軸樞設使用，而由於含油軸承是以粉末沖壓成型後經由燒結浸油而成，在含油軸承的本體中具有氣孔，可使浸入的潤滑油在心軸旋轉時能滲出提供潤滑作用，又，已知的含油軸承與軸套的組裝設置，是以外力將含油軸承迫入軸套內部，使含油軸承能緊密的結合在軸套內壁當中，而由於含油軸承在迫入時，會朝內徑方向縮徑變形，雖然，該變形尺寸很小，但是對於轉子心軸的樞設旋轉仍有不良影響，例如穿孔中心的偏差及歪斜會產生旋轉噪音，以及含油軸承內壁面變形，會造成心軸接觸時之強硬摩擦產生旋轉噪音，使馬達壽命減短。
另有習知業者以複數種材料粉末混合使用，但換材料僅為對整體性質之調整，對於實質物理性質想做到差異化，卻沒有幫助。
The bearing is a structure that can provide the motor rotor core shaft, which can reduce the wear of the fan shaft seat and prolong the life of the fan. Among the known bearing structures, there is a oil bearing with self-lubricating effect, which has been widely installed. It is set in the bushing of the small motor for the pivoting of the mandrel. Since the oil-impregnated bearing is formed by sintering and immersing oil after the powder is formed, the air bearing in the body of the oil-impregnated bearing can rotate the immersed lubricating oil in the mandrel. The oozing can provide lubrication. Moreover, the known assembly of the oil-impregnated bearing and the bushing is to force the oil-impregnated bearing into the inner part of the bushing by external force, so that the oil-impregnated bearing can be tightly integrated in the inner wall of the bushing, and because of the oily When the bearing is forced into, it will be deformed in the direction of the inner diameter. Although the deformation is small, it still has an adverse effect on the pivoting rotation of the rotor shaft. For example, the deviation and skew of the center of the perforation may generate rotational noise, and The deformation of the inner wall surface of the oil-impregnated bearing causes the hard friction during the contact of the mandrel to generate rotational noise, which shortens the life of the motor.
Others have used a mixture of powders of various materials, but the material change is only an adjustment to the overall properties, and it is not helpful to make a difference in the physical properties.
