    • Apparatus and methods for assembling a piston assembly that comprises a piston comprising a head end flange and a crank end flange and a rod having a head end shoulder and a crank end shoulder. The head end shoulder of the rod contacts the head end flange of the piston and the crank end shoulder of the rod contacts the crank end flange of the piston. A nut engages the rod such that the head end flange of the piston is disposed between the nut and the head end shoulder of said rod. A collar engages the piston such that the crank end shoulder of the rod is disposed between the collar and the crank end flange of the piston.
    • 一种用于组装活塞组件的装置和方法,该活塞组件包括一个活塞,该活塞包括头端凸缘和曲柄端凸缘以及具有头端肩部和曲柄端肩部的杆。 杆的头端肩接触活塞的头端凸缘,杆的曲柄端肩接触活塞的曲柄端凸缘。 螺母接合杆,使得活塞的头端凸缘设置在螺母和所述杆的头端肩部之间。 套环接合活塞,使得杆的曲柄端肩部设置在套环和活塞的曲柄端凸缘之间。

    • In accordance with certain embodiments, a modular crankshaft features a connection system between modules that features opposed female receptacles. A pin having opposed beveled ends and hydraulic passages with it is inserted into the opposed receptacles. A pair of seals is disposed on the beveled ends and straddles a hydraulic fluid outlet. The crankshaft wall that defines each receptacle is designed to flex in response to applied hydraulic pressure between the seals on the tapered pin portion. A notch at the base of the receptacle in the crankshaft reduces stress concentration and enables the wall defining the crankshaft receptacle to come back when hydraulic pressure through the pin is removed. The opposed crankshaft receptacles are flanged to allow them to be pulled together over the pin. An interference fit results around the pin after the flanges are mated and the hydraulic pressure is removed.
    • 根据某些实施例,模块化曲轴具有在相对的插座之间的模块之间的连接系统。 具有相对的倾斜端部的销和其液压通道插入相对的插座中。 一对密封件设置在斜面上并横跨液压流体出口。 限定每个容器的曲轴壁被设计成响应于锥形销部分上的密封件之间施加的液压而弯曲。 曲轴底座底部的切口减少了应力集中,并且当通过销的液压被去除时,能够使限定曲轴接收器的壁返回。 相对的曲轴接收器是带凸缘的,以允许它们在销上拉到一起。 在法兰配合后,并且液压被去除时,在销周围产生过盈配合。
