PURPOSE: A rotor head device of a model helicopter is provided to keep a vibration amount generated in both sides of a spindle when a main wing rotates and equally generate vibration in up/down/left/right directions, thereby stabilizing the pitch of both sides of the main wing. CONSTITUTION: A rotor head device of a model helicopter includes a yoke device(10), a spindle(40), a spherical bearing(50), a bearing fixing cover(60), and a rubber packing(33). The yoke device includes a vertical yoke(20) and a horizontal yoke(30). A spindle is inserted into a through hole(31) of a horizontal yoke. A rotor grip with which a main wing is coupled is formed on both ends of the spindle. The bearing fixing cover is inserted into a connection hole of a horizontal yoke to support a spherical bearing from the inside of the horizontal yoke. The rubber packing is installed between both through holes and a spindle of the horizontal yoke. Vibration and an impact during rotation of the main wing are absorbed to prevent the vibration and an impact from being delivered to a rotation shaft. |
