A ring gear includes teeth ( 10 ) and tooth gaps ( 12 ), in which the teeth ( 10 ) can be brought vie tooth flanks ( 14 ) into engagement with a corresponding pinion. The tooth flanks ( 14 ), after a final engagement point ( 16 ) of the pinion, from the tooth head ( 18 ) toward the tooth base ( 20 ), compared to standard tooth flanks ( 22 ), are made to approximate a trochoid ( 24, 26 ), described by the pinion and projected into a normal section. |
