繁體:曲柄銷/偏心軸頸
曲柄销或偏心轴颈是偏心轴或曲轴上偏离主旋转轴线的精密加工圆柱面。
曲柄销或偏心轴颈是偏心轴或曲轴上偏离主旋转轴线的精密加工圆柱面。该偏移产生偏心距,通过连杆或连接机构将连续旋转输入转换为受控的直线或摆动输出运动。在工业应用中,它是发动机、泵、压缩机及各种机械系统中旋转轴与往复部件之间的关键接口。 基于偏心运动原理,轴颈中心与轴旋转轴线之间的偏移距离(偏心距)形成曲柄机构。当轴旋转时,轴颈沿圆周路径运动,通过连接的连杆将旋转能量转换为直线位移。机械效益取决于偏心距半径和角位置。

While functionally similar, crankpins typically refer to components in multi-cylinder engines where they connect rods to crankshafts, while eccentric journals are single-offset features on shafts for creating reciprocating motion in various industrial machines.
Eccentricity is measured as the radial distance between the journal center and shaft rotational axis using coordinate measuring machines (CMM) or dial indicators. Control is maintained through precision machining, balancing, and strict tolerance adherence.
Regular lubrication, wear inspection, clearance checks, and balancing verification. High-cycle applications may require periodic re-machining or replacement due to fatigue and wear.
