【Abstract】 Based on the general planetary gear drive with small teeth difference, the improved design of X Y planetary gear drive for increasing speed was presented in the paper. The planetary gears are in translational motion in X Y plane and their rotations are limited. It was proved that this type of speed increaser has better bearing capacity, operating stability and speed increasing ability by kinetic analyses. The key problem of improved design of the speed increaser for the BORDA pump (river current powered pump) was solved satisfactorily.更多还原
