The plunger harmonic transmissions and the principle of its operation is considered as the construction of a new kind of mechanisms for the transformation of movement. The problem of geometrical synthesis of a gear engagement of plunger harmonic transmission with circular working surface of the plunger and the traj ectory of its movement by a circumscribed arc of a fixed radius is formulated and solved. The theoretical solution is illustrated by a numerical example from the practice of design of a plunger transmission of an experimental reducer.
