    • A cam pin system, includes a cam pin comprising a first cylindrical portion having a first length and a first diameter and a second cylindrical portion concentric with the first cylindrical portion and having a second diameter larger than the first diameter, the second cylindrical portion comprising a through-hole to accommodate the passage of a firing pin. The system includes an end plate detachably connected to the first cylindrical portion of the cam pin, a cylindrical bushing encircling the first cylindrical portion and having an outside diameter approximately equal to the second diameter and a bushing length approximately equal to the first length, and lubricant between the cylindrical bushing and the first cylindrical portion. The cam pin system is configured so that the cylindrical bushing can rotate freely about the first cylindrical portion.
    • 凸轮销系统包括凸轮销,凸轮销包括具有第一长度和第一直径的第一圆柱形部分和与第一圆柱形部分同心并且具有大于第一直径的第二直径的第二圆柱形部分,第二圆柱形部分包括 通孔以容纳撞针的通过。 该系统包括可拆卸地连接到凸轮销的第一圆柱形部分的端板,围绕第一圆柱形部分并且具有大致等于第二直径的外径和大致等于第一长度的衬套长度的圆柱形衬套,以及润滑剂 在圆柱形衬套和第一圆柱形部分之间。 凸轮销系统构造成使得圆柱形衬套能够围绕第一圆柱形部分自由旋转。
