The invention provides a main propeller hub of an unmanned helicopter. The main propeller hub of the unmanned helicopter comprises a main shaft and a main propeller hub body, wherein the main propeller hub body comprises a mounting block connected with the main shaft, a mounting rod penetrating through the mounting block, and a propeller clamp fixedly connected with the mounting rod; a first through hole is formed in the mounting block, and the two ends of the first through hole are connected with damping devices; the damping device comprises a first arc-shaped plate, a second arc-shaped plate, an arc-shaped groove and a damping plate, wherein the second arc-shaped plate is matched with the first arc-shaped plate to form a complete circle, and the damping plate is connected with the arc-shaped groove in a sliding mode. The propeller hub has the beneficial effects that by arranging the main propeller hub body, the purpose of connecting the propeller blades can be achieved; through the arrangement of the damping device, the vibration force of the propeller clamp on the mounting block can be reduced or eliminated as much as possible when the main propeller hub body rotates; and through the arranged main shaft, the main propeller hub body can be supported, and the main propeller hub body is driven to rotate.
