摘要: 
軸承是軸或者旋轉機械的重要支承,軸承損壞將造成機械無法運轉。損壞主要原因為軸承滾動體受力不平均或者是與保持器碰撞,導致保持器不穩定影響軸承整體運轉,所以了解保持器的穩定性以及滾柱受力是相當重要的一環。本文利用NU型單列滾柱軸承作為分析對象,並使用機構動態模擬分析軟體RecurDyn分析軸承之動態特性,探討藉由改變軸承內環轉速、外部徑向載荷、有、無徑向間隙對保持器運動與滾柱所造成影響。由分析結果可發現,內環轉速提升,會使保持器運動更穩定且滾柱接觸受力會增加;而改變三種外部徑向載荷,對保持器穩定性並沒有影響;無徑向間隙時保持器穩定性則會較有間隙時佳,但保持器轉速則無影響。

Bearing is an important support of axle or rotary machinery. The damage of bearing will cause the machinery unable to run. The main reason to cause damage of bearing is uneven force acting on the roller or roller colliding with the cage. It will cause the cage becoming unstable then influence the rotation of bearing. Therefore, it is very important to understand the stability of cage and force acting on roller.
The NU type single row cylindrical roller bearing is analyzed in this study by using the multi body simulation software “RecurDyn” to understand the dynamic characteristic of this bearing. The running condition of cage and roller are analyzed for different inner rotational speeds, radial loads, and with and without radial clearance. The results show that the cage will be more stable and the force acting on roller will be higher for higher inner rotational speed. However, changing the radial loads will not affect the stability of cage. The stability of cage for situation of no radial clearance is better than having radial clearance, but the rotational speed of cage remains the same.
