The invention relates to a helicopter rotor control universal joint which comprises a ball joint, a bearing outer ring, a bearing inner ring and a roller, the roller is mounted between the bearing outer ring and the bearing inner ring, and an inner spherical surface in sliding fit with an outer spherical surface of the ball joint is arranged on the bearing inner ring. The stress in different directions can be effectively converted into trace sliding friction, so that the damage of the strong stress to the structure is greatly reduced, the movement of a propeller in the flying process of an airplane is smoother, the resonance risk is reduced, and the structural safety is greatly improved.
本发明涉及一种直升机旋翼控制万向关节,包括球头关节、轴承外圈、轴承内圈以及滚柱,所述滚柱安装在所述轴承外圈与所述轴承内圈之间,所述轴承内圈上开设有与所述球头关节的外球面滑动配合的内球面。其能够有效的将不同方向的应力转为微量的滑动摩擦,从而大大降低了这些强应力对结构造成的损伤,能使飞机在飞行过程中螺旋桨的运动更加顺畅,并降低了共振风险,大大提升了结构安全性。
