A wind-powered propulsion rotor, inner tower and outer cylinder

Abstract

This utility model discloses a wind-powered booster rotor, an inner tower, and an outer cylinder, belonging to the technical field of wind-powered booster rotors. The wind-powered booster rotor includes an outer cylinder and an inner tower. The inner tower is fitted over the outer cylinder, supporting and driving the outer cylinder to rotate. A turntable is fixed inside the outer cylinder, and an upper support member is fixed on the inner tower. A first rolling element is provided between the turntable and the upper support member. This utility model achieves load distribution through multi-point contact by setting the upper support member with the first rolling element and the turntable with movable grooves between the outer cylinder and the inner tower, and reduces surface wear through rolling contact. In addition, several limiting mechanisms are provided between the outer cylinder and the inner tower, which restrict the relative sway between the two, ensuring rotational coaxiality and stability.
