Each spool support is coupled to a respective motor by means of a drive coupling providing at least one fixed transmission ratio.
每个卷轴支撑装置由提供至少一个固定传输比的驱动耦合装置耦合到对应的电机；
The drive coupling is configured to engage a driven member, with the drive coupling defining a drive axis that is not coaxial with the bit axis.
驱动连接件被构造成接合从动元件，同时驱动连接件限定了与钻头轴线不同轴的驱动轴线。
Rotation of the driven member and associated drive coupling operates the drive train and results in rotation of the bit mount and associated router bit.
从动元件以及相关联的驱动连接件的旋转操作传动机构并导致钻头安装件以及相关联的刳刨机钻头的旋转。
Transmission : normally meshed helical gear drive, coupling sleeve shift and two lever operation. The transmission has five forward speeds and four backward speeds .
变速箱采用常啮斜齿轮传动，结合套换档、双杆机械操纵，前进五档、后退四档。
