Method of manufacturing asymmetric gear, asymmetric gear, non-circular and asymmetric gear, gear mechanism, and barrel finishing machine

Abstract

An object of the present invention is to provide a practical gear and gear train which can be used in an actual gear drive system. Another object of the present invention is to provide a non-circular and asymmetrical gear which is practically used in view of durability, a gear train using that gear, and a barrel finishing machine using that gear. Non-circular and asymmetrical gear 10 has a plurality of tooth profiles 20, each of which comprises a substantially semicircular top curve line 16 and a substantially semicircular bottom curved line 18. A center point 22 of the top curved line 16 is on a pitch line 24, and a center point 26 of the bottom curved line 18 lies inside the pitch line 24.
