依靠曲軸的高速轉(zhuǎn)動,把氣缸體下部的潤滑油飛濺到小頭頂端的油孔內(nèi),以潤滑連桿小頭襯套與活塞銷之間的擺動運動副。 連桿的作用是把活塞和曲軸聯(lián)接起來,使活塞的往復(fù)直線運動變?yōu)榍幕剞D(zhuǎn)運動,以輸出動力。因此,連桿的加工精度將直接影響柴油機的性能,而工藝的選擇又是直接影響精度的主要因素。反映連桿精度的參數(shù)主要有 5 個:( 1)連桿大端中心面和小端中心面相對連桿桿身中心面的對稱度;( 2)連桿大、小頭孔中心距尺寸精度;( 3)連桿大、小頭孔平行度;( 4)連桿大、小頭 孔尺寸精度、形狀精度;( 5)連桿大頭螺栓孔與接合面的垂直度。 Automobile connecting rod machining process Connecting rod structure characteristic The connecting rod is one of the main driving parts of automobile engine , It in a diesel engine , pass on the piston top surface of expansive pressure to the crankshaft , And the crankshaft drive to bring the piston preses the airin the air cylinder . Connecting rod bearing dynamic lood of dramatic changes in the work . The connecting rod by a connecting rod and connecting rod cap of two parts . Connecting rod and coning rod cap on the big hole by bolts and muts and crankshaft mount
