    • A traction drive system for an articulated robotic arm. The traction drive system can include an input drive disk, a spider, an array of traction balls, a traction plate, an output drive shaft, a clamping device to load the traction balls, and an absolute rotation position sensor system. The rotation of the output drive shaft can be coupled to the rotation of the input drive disk while the traction balls are frictionally engaged to the drive disk surface and traction plate surface. The rotational connection can be decoupled when the traction balls are not frictionally engaged to the drive disk surface and traction plate surface. A rotational position sensor located in proximity to the traction drive can provide absolute rotational position feedback of the output drive shaft.
    • 用于铰接式机器臂的牵引驱动系统。 牵引驱动系统可以包括输入驱动盘,蜘蛛,牵引球的阵列,牵引板,输出驱动轴,用于装载牵引球的夹紧装置和绝对旋转位置传感器系统。 输出驱动轴的旋转可以与输入驱动盘的旋转耦合,同时牵引球摩擦地接合到驱动盘表面和牵引盘表面。 当牵引球没有摩擦地接合到驱动盘表面和牵引板表面时,旋转连接可以被去耦。 位于靠近牵引驱动器的旋转位置传感器可以提供输出驱动轴的绝对旋转位置反馈。
