    • A compact capstan includes a drum, a coupled hub, a passage extending through the drum and hub, and a shaft extending through the drum and hub. The shaft engages the passage such that the shaft can transmit a torsional force to the drum and the hub which are free to move along the length of the shaft. The drum includes a spiral groove to receive a cable loop wound around the drum. The hub has a thread with substantially the same pitch as the spiral groove to engage a threaded support such that the hub and the drum move laterally along their length relative to the threaded support as the hub and the drum are rotated. The shaft has a length that is substantially greater than the passage such that the shaft extends beyond both ends of the passage.
    • 紧凑型绞盘包括鼓,联接轮毂,延伸穿过滚筒和轮毂的通道以及延伸穿过滚筒和轮毂的轴。 轴与通道接合,使得轴可以向滚筒和轮毂传递扭转力,该扭转力可随着轴的长度而自由移动。 滚筒包括螺旋槽,用于接收缠绕在滚筒上的电缆环。 轮毂具有与螺旋槽基本上相同的螺距的螺纹,以与螺纹支撑件接合,使得当毂和滚筒旋转时,轮毂和滚筒相对于螺纹支撑件沿其长度方向横向移动。 轴具有基本上大于通道的长度,使得轴延伸超过通道的两端。
