PURPOSE: A gear coupling using a bevel gear is provided to minimize a shaft-angle error, shaft fluxion, and a parallel error by using a sphere involute bevel gear. CONSTITUTION: A gear coupling using a bevel gear comprises an inscribed hub(110), and a circumscribed hub(120). The inscribe hub has one side combined with a first rotary shaft, and an inscribe bevel gear(112) is formed along the circumference of the other side of the inscribe hub at an tilt. A circumscribe hub has one side combined with a second rotary shaft, and an circumscribe bevel gear(122) is formed along the circumference of the circumscribe hub at a tilt. The circumscribed hub is meshed with the inscribe bevel gear while forming backlash. The first rotary shaft and the second rotary shaft are formed to transfer the power in spite of the formation of a shaft-angle. The inscribed hub comprises a first pivot holder(130) pivotally combined by a first thrust bearing. The circumscribed hub comprises a second pivot holder(140) pivotally combined by a second thrust bearing.
