    • A backlash reducer for a gear transmission system comprises a main gear and an auxiliary gear which form one of a driving gear and a driven gear in mesh therewith of the gear transmission system. The main gear is mounted on a rotary shaft for rotation therewith, and the auxiliary gear is mounted on the rotary shaft for rotation relative thereto. A backlash reducing mechanism is operable in response to a centrifugal force due to rotation of the rotary shaft for angularly moving the main and auxiliary gears relative to each other to reduce a backlash between the driving and driven gears. The backlash reducer may further comprise a mechanism for restraining the backlash reducing action of the backlash reducing mechanism. Alternatively, the backlash reducer may comprise a first mechanism operable in response to the centrifugal force to move the auxiliary gear axially thereof and a second mechanism for converting the axial movement of the auxiliary gear to circumferential movement thereof.
    • 用于齿轮传动系统的齿隙减速器包括主齿轮和辅助齿轮,所述主齿轮和辅助齿轮形成与齿轮传动系统啮合的驱动齿轮和从动齿轮中的一个。 主齿轮安装在旋转轴上以与其一起旋转,辅助齿轮安装在旋转轴上以相对于其旋转。 齿隙减小机构响应于由于旋转轴的旋转而产生的离心力而可操作,用于相对于彼此角主动地移动主齿轮和辅助齿轮,以减少驱动齿轮与从动齿轮之间的间隙。 齿隙减速器还可以包括用于抑制齿隙减速机构的齿隙减小作用的机构。 或者,齿隙减速器可以包括可响应于离心力而使辅助齿轮沿轴向运动的第一机构和用于将辅助齿轮的轴向运动转换成其周向运动的第二机构。
