摘要： A head drum apparatus comprises: a lower drum; a stationary shaft pressed and fitted into a center hole of the lower drum; an upper drum rotatably coupled to the stationary shaft via at least one bearing; a boss fixed to the top portion of the stationary shaft by means of a set-screw; a motor rotor mounted to the top surface of the upper drum; a motor stator fixed to the boss, the motor stator being opposite to the motor rotor; and a ground device. The ground device includes an anchor member anchored to the upper surface of the boss and an elastic member fixed to the bottom surface of the anchor member. The elastic member extends downwardly through a bore in the boss, and a ground member is fixed to tile lower end of the elastic member. The ground member is in elastic contact with an outer race of an upper bearing. Accordingly, the assembly and the disassembly operations of the components of the ground device become simpler and easier, thereby increasing the productivity and enhancing the service operation efficiency thereof.
