Anti-overturning swivel spherical hinge
The invention provides an anti-overturning swivel spherical hinge which comprises an upper spherical hinge body and a lower spherical hinge body, and the upper spherical hinge body and the lower spherical hinge body are assembled in a spherical surface rotating mode. The cross sections of the matched surfaces of the upper spherical hinge and the lower spherical hinge are omega-shaped, each matched surface comprises a spherical surface and an annular plane extending in the circumferential direction of the spherical surface, and a gap is formed between the annular plane of the upper spherical hinge and the annular plane of the lower spherical hinge. The matching surface of the upper spherical hinge and the lower spherical hinge is an omega-shaped kinematic pair, wherein the spherical surface realizes the horizontal rotation of the anti-overturning spherical hinge. The annular planes additionally extending from the peripheries of the spherical surface edges of the upper spherical hinge and the lower spherical hinge are utilized to form a plane moving kinematic pair structure, when the overturning angle generated by the swivel spherical hinge reaches a design value, the upper annular plane and the lower annular plane of the omega-shaped edge can generate local contact limiting and provide anti-overturning moment, and therefore the swivel T-shaped structure is stopped from continuously overturning; and the rotation process is kept stable.
本发明提供了一种抗倾覆转体球铰，包括上球铰和下球铰，上球铰和下球铰呈球面转动装配；上球铰与下球铰相互配合的面的横截面均为Ω形状，所述配合面包括球面和沿球面周向伸出的环形平面，上球铰的环形平面和下球铰的环形平面之间具有间隙。本发明上球铰和下球铰的配合面为Ω形状组成的运动副，其中的球面实现抗倾覆球铰的水平转动。利用上下球铰球面边缘圆周额外延伸设计成的环形平面，形成平面移动运动副结构，当转体球铰产生的倾覆转角达到设计值时，Ω形状的边缘的上下环形平面会产生局部接触限位，提供抗倾覆力矩，从而终止转体T构继续倾覆，使转体过程保持稳定。
