    • A cam phaser (30, 130, 230) dynamically adjusts a rotational relationship of a camshaft (32) of an internal combustion engine with respect to an engine crankshaft operably connected with a phaser sprocket (42, 142, 242). The cam phaser (30, 130, 230) can include a planetary gear assembly having a ring gear (34, 134, 234) driven by the phaser sprocket (42, 142, 242), a planetary gear carrier (36, 136, 236) connected to the camshaft (32), a sun gear (38, 138, 238), and at least one rotatable planetary gear (40, 140, 240). The cam phaser (30, 130, 230) can include a sprocket housing (44, 144, 244) connected with the phaser sprocket (42, 142, 242) and operable for connection with the ring gear (34, 134, 234), a cover plate (46, 146, 246) secured to the carrier (36, 136, 236), and a adapter (48) connected between the sun gear (38, 138, 238) and an electric motor (47) for changing an angular position of the sun gear (38, 138, 238) and adjustably varying a cam phase position of the camshaft (32) relative to the crankshaft.
    • 凸轮相位器(30,130,230)相对于与移相链轮(42,142,242)可操作地连接的发动机曲轴动态调节内燃机的凸轮轴(32)的旋转关系。 凸轮相位器(30,130,230)可包括行星齿轮组件,该行星齿轮组件具有由相移器链轮(42,142,242)驱动的环形齿轮(34,134,234),行星齿轮架(36,136,236) )连接到凸轮轴(32),太阳齿轮(38,138,238)和至少一个可旋转的行星齿轮(40,41,240,240)。 凸轮相位器(30,130,230)可以包括与移相链轮(42,42,242)连接并且可操作以与环形齿轮(34,134,234)连接的链轮壳体(44,144,244), 固定到所述载体(36,136,236)的盖板(46,146,246)和连接在所述太阳齿轮(38,138,238)和电动机(47)之间的适配器(48),用于改变 太阳齿轮(38,138,238)的角度位置,并且相对于曲轴可调节地改变凸轮轴(32)的凸轮相位置。
