초록
This paper presents a design procedure for a face gear and pinion used in a handpiece with a 160°ýcontra angle and 1:2 gear ratio. Based on the geometric theory of gearing, the tooth profile of the face gear andpinion is developed. To analyze the contact pressure, the gear profile should be determined before calculatingthe stress between the two gears. The concept of calculating the face gear profile is that it can be generated bythe coordinate transformation of the shaper profiles, which have involute curves, using a simulation method fromthe gear manufacturing process.
