推力発生装置
Document Type and Number:
Japanese Patent JP7452322
Kind Code:
B2
Abstract:
To suppress deterioration in variable accuracy of pitch angles on the basis of rotational motion converted from linear motion.SOLUTION: A thrust generating device includes a first conversion part which converts rotational motion of a second motor for generating the rotational motion for changing pitch angles of a rotor to linear motion, and a second conversion part which converts the linear motion converted by the first conversion part to the rotational motion. The second conversion part includes a linear motion body which can linearly move in accordance with the linear motion converted by the first conversion part, a rack-and-pinion which converts the linear motion converted by the first conversion part to the rotational motion, a case which stores the linear motion body and the rack-and-pinion, and an energizing member which generates pressing force in a direction for pressing a rack of the rack-and-pinion against a pinion. The rack is supported by the linear motion body, and the pinion is supported by a support shaft side of the rotor.SELECTED DRAWING: Figure 12
