Abstract

The mechanism consists of rotating joint, connecting bar possessing motion degree of freedom, central constraint pole, upper platform and lower platform. Revolving axis of the rotating joint is connected to the upper platform rigidly. One end of the central constraint pole is connected to the center of the lower platform rigidly, and the other end is connected to the upper platform through a ball pair. Two ends of two pieces of connecting bar possessing motion degree of freedom are connected to upper platform and lower platform through ball pairs, and distributed on a circle with a crossing point between the central constraint pole and platform being as circle center. The invention realizes interlocked rotations around three coordinate axes. Continuous turning can be realized in rolling degree of freedom, rotating range of other two-degree of rotational freedom is not large. The invented mechanism is utilized to application needed of high rigidity and small sectional area.
