This paper describes the manufacture of injection-molded plastic magnetic gears. The polarity of the right tooth face is different from that of the left tooth face in all teeth. Such gears mesh with either nonbacklash or noncontact gears. This paper describes the former. If practical the nonbacklash gears should be used in such applications as measurement meters and the joints of robots due to their accurate rotary transmission. This first paper was written primarily on the principle of plastic magnetic gears regarding the method of injection, molding-method of magnetization and measurement of flux density. It was possible to put the injection-molded plastic magnetic gears to practical use in this experiment.
