The disadvantage of current compliant pairs used in micro-displacement fields are that they produce micro-deformation rather than macro-scale deformation. In order to solve this problem, a new compliant revolute pair was proposed based on the theory of elastic deformation which can provide macro-scale deformation according to its own elastic deformation. The model of flexibility matrix was established, and rotation error was calculated with Matlab software and analyzed in Ansys. The results showed that the relative rotational stiffness error was 5.6% and relative rotation error was 3.4% according to the two methods. Finally, a test of the compliant revolute pair was carried out to justify the two above-mentioned results. It showed the flexibility analysis is reasonable.
