    • The invention relates to an oscillatory driving device for a hand-held power tool (12a; 12b; 12c; 12d; 12e; 12f; 12g), comprising at least one input shaft (14a; 14b; 14c; 14d; 14e; 14f; 14g), at least one output shaft (16a; 16b; 16c; 16d; 16e; 16f; 16g), and at least one gearing unit (18a; 18b; 18c; 18d; 18e; 18f; 18g), which operatively connects the input shaft (14a; 14b; 14c; 14d; 14e; 14f; 14g) to the output shaft (16a; 16b; 16c; 16d; 16e; 16f; 16g) and which comprises at least one eccentric element (20a; 20b; 20c; 20d; 20e; 20f; 20g) for driving the output shaft (16a; 16b; 16c; 16d; 16e; 16f; 16g) in an oscillatory manner. According to the invention, the gearing unit (18a; 18b; 18c; 18d; 18e; 18f; 18g) comprises at least one further eccentric element (22a; 22b; 22c; 22d; 22e; 22f; 22g) for driving the output shaft (16a; 16b; 16c; 16d; 16e; 16f; 16g) in an oscillatory manner.
    • 本发明涉及用于手持式工具机(12a; 12b; 12c; 12d; 12e; 12f; 12g)的振动驱动装置,其包括至少一个输入轴(14a; 14b; 14c; 14d; 14e; 14f; 至少一个输出轴(16a; 16b; 16c; 16d; 16e; 16f; 16g);以及至少一个传动单元(18a; 18b; 18c; 18d; 18e; 18f; 18g),其可操作地连接 输入轴(14a; 14b; 14c; 14d; 14e; 14f; 14g)与输出轴(16a; 16b; 16c; 16d; 16e; 16f; 16g)连接并且包括至少一个偏心元件(20a; 20b; 20c ; 20d; 20e; 20f; 20g),用于以摆动方式驱动输出轴(16a; 16b; 16c; 16d; 16e; 16f; 16g)。 根据本发明,传动单元(18a; 18b; 18c; 18d; 18e; 18f; 18g)包括用于驱动输出轴的至少一个另外的偏心元件(22a; 22b; 22c; 22d; 22e; 22f; 22g) (16a; 16b; 16c; 16d; 16e; 16f; 16g)以振荡方式。
