通常日本nsk軸承會(huì)出現(xiàn)粘滑振動(dòng)、表面幾何誤差引起的振動(dòng)、摩擦轉(zhuǎn)化導(dǎo)致的非線性振動(dòng)與自激振動(dòng)。零件的表面粗糙度對(duì)軸承噪聲有顯著影響。實(shí)際上日本nsk軸承零件的表面是粗糙表面,表面接觸模型和分析方法是研究軸承振動(dòng)的兩個(gè)關(guān)鍵。
(1)在表面凸峰處接觸振動(dòng)很小,而在表面凹陷處接觸振動(dòng)的振動(dòng)速度、加速度很大。
(2)轉(zhuǎn)速越高則振動(dòng)越大;在日本nsk軸承零件加工要求的表面粗糙度范圍內(nèi),表面粗糙度的對(duì)接觸振動(dòng)影響不大;接觸載荷越大,則在凹陷處的接觸振動(dòng)加速度變化越大。
