In this paper

a kind of a positioning scheme for the incomplete gear intermittent structure is proposed and such problems as multiple transmission series

inaccurate positioning of position

influence of positioning accuracy by the machining and assembly accuracy and large space occupation of the mechanism are solved. The result has both novelty and practicability. The theoretical analysis and design of this positioning principle is firstly performed

then the test result of the sample is given. It is proved by the test result that the scheme has simple structure

small transmission series

small space occupation and can achieve the needed positioning accuracy after assembly

which can achieve accurate positioning of the electric operation of the three position disconnector and has been used widely in the projects.
