Unlike a cylindrical gear, crossing of two gear shafts occurs in a bevel gear, so its tooth bearing changes sensitively with assembly error, shaft angle error and deviation of apex, and the tooth end contact is easily caused. To prevent the tooth and contact, crowning of a tooth flank is performed by means of a coniflex gear. The practicality of a crowning gears is well recognized and they has been used in many industrial applications. It is important for strength design to know the load distribution on a line of contact and the tooth root stress of the bevel gear where crowning was performed. In this paper, the load distribution and the tooth root stress distribution of coniflex gears are calculated. These calculated values were compared with measured values, and validity of this calculation method was examined.
