    • A vibratory power unit (10, 210) having small gasoline engine (12) coupled by a drive shaft (15) extending through a semi-rigid shaft case (16, 18, 20) to an eccentric (75) rotating with the aid of sealed bearings (74, 78) within a vibrator case (14, 514) is disclosed. The semi-rigid shaft case includes a first rigid shaft case portion (16) and a second rigid shaft case portion (20) coupled together by an isolator (18, 518, 618). A coupling (90, 790) is provided for removably coupling the vibratory power unit (10, 210) to concrete finishing tools (11, 211). The coupling includes a split ball (92) configured to be received on the vibrator case (14, 514) and a slit ring (110) configured to compress the split ball (92) onto the vibrator case (14, 514). A radio controlled throttle controller (300, 400, 500) is provided for remotely controlling the speed of engine (12). Radio controlled throttle controller (300, 400) scavenges electrical power from the magneto circuitry of the engine (12).
    • 具有小型汽油发动机(12)的振动动力单元(10,210),所述小型汽油发动机(12)由延伸穿过半刚性轴壳(16,18,20)的驱动轴(15)联接到借助于 公开了在振动器壳体(14,514)内的密封轴承(74,78)。 半刚性轴壳体包括由隔离器(18,518,618)联接在一起的第一刚性轴壳体部分(16)和第二刚性轴壳体部分(20)。 提供联接器(90,790),用于将振动动力单元(10,210)可拆卸地联接到混凝土精加工工具(11,211)。 联接器包括构造成接收在振动器壳体(14,514)上的分离球(92)和构造成将分离球(92)压缩到振动器壳体(14,514)上的狭缝环。 提供无线电控制节流控制器(300,400,500)以远程控制发动机(12)的速度。 无线电控制节流控制器(300,400)清除来自发动机(12)的磁电路的电力。
