    • A reciprocating piston mechanism (1) comprises a crankcase (15) and a crankshaft (2) which has at least a crankpin (4). The crankshaft (2) is supported by the crankcase (15) and rotatable with respect thereto about a crankshaft axis (5). The mechanism further comprises at least a connecting rod (9) including a big end (8) and a small end (10), a piston (11) which is rotatably connected to the small end (10), and a crank member (6) which is rotatably mounted on the crankpin (4). The crank member (6) comprises at least a bearing portion (7) and has an outer circumferential wall which bears the big end (8) of the connecting rod (9) such that the connecting rod (9) is rotatably mounted on the bearing portion (7) of the crank member (6) via the big end (8). The crank member (6) is provided with a crank member gear (12). The crank member gear (12) is an external gear, which meshes with at least an intermediate gear (13). The intermediate gear (13) is an external gear, which also meshes with an auxiliary gear (14). The auxiliary gear (14) is an external gear, which is fixed to an auxiliary shaft (16) that extends concentrically through the crankshaft (2). The crankshaft (2) and the auxiliary shaft (16) are rotatable with respect to each other.
    • 往复式活塞机构(1)包括曲轴箱(15)和至少具有曲柄销(4)的曲轴(2)。 曲轴(2)由曲轴箱(15)支撑并且可相对于曲轴(5)绕曲轴旋转。 该机构还包括至少一个连杆(9),该连杆包括一个大端(8)和一个小端(10),一个可旋转地连接到小端(10)的活塞(11),以及一个曲柄件 ),其可旋转地安装在曲柄销(4)上。 所述曲柄部件(6)至少包括轴承部分(7)并且具有承载连杆(9)的大端部(8)的外周壁,使得连杆(9)可旋转地安装在轴承 (8)的曲柄部件(6)的部分(7)。 曲柄部件(6)设置有曲柄部件齿轮(12)。 曲柄部件齿轮(12)是至少与中间齿轮(13)啮合的外齿轮。 中间齿轮(13)是外齿轮,其也与辅助齿轮(14)啮合。 辅助齿轮14是外齿轮,其被固定到同心地延伸穿过曲轴2的辅助轴16。 曲轴(2)和副轴(16)可相对于彼此旋转。
