摘要： The present invention relates to a method of manufacturing a connecting rod assembly having a stepped small end. The method includes defining a small end (56) of a connecting rod assembly having a terminal end and defining a pin bore (64) extending therethrough. A pair of channels (66, 68) are formed on opposite sides of the small end (56), perpendicular to the pin bore (64) and a bushing (82) is subsequently installed into the pin bore (64). Where a connecting rod assembly does not include a bushing the method includes defining a small end having a pin bore and forming pair of channels on opposite sides of the small end. A contact surface is then defined within the pin bore to engage a piston pin and the small end is machined to provide a stepped configuration. The connecting rod assembly is then machined to reduce the width of the small end to provide a stepped configuration.

摘要翻译： 本发明涉及制造具有阶梯式小端的连杆组件的方法。 该方法包括限定具有终端并限定延伸穿过其中的销孔的连杆组件的小端。 一对通道形成在小端的相对侧上，垂直于销孔，并且衬套随后安装到销孔中。 在连杆组件不包括衬套的情况下，该方法包括限定具有销孔的小端并且在小端的相对侧上形成一对通道。 然后在销孔内限定接触表面以接合活塞销，并且小端被加工以提供阶梯式构造。 然后对连杆组件进行机加工以减小小端的宽度以提供阶梯式构造。
