The present invention relates to a gear coupling using a bevel gear, and particularly, to a gear coupling for connecting and transmitting power between a first rotating shaft and a second rotating shaft through gear engagement, the gear coupling comprising: an internal hub having a cylindrical shape with one end coupled to the first rotating shaft, and an internal bevel gear formed at an angle in and along a circumference of the other end thereof; an external hub having a cylindrical shape with one end coupled to the second rotating shaft, and an external bevel gear formed angled outward around a circumference of the other end thereof and meshed with the internal bevel gear to form a backlash; a first pivot holder rotatably coupled inside the internal hub; and a second pivot holder rotatably coupled inside the external hub and coupled via a hinge to the first pivot holder, wherein power can be transmitted even when a shaft angle is formed between the first rotating shaft and the second rotating shaft, and power can be transmitted even with shaft lines which are offset when a pair of the gear couplings is used to form shaft angles, such that power density is superior to that of the prior art, and as locking does not occur, there is no bending moment and no deviation in velocity transfer, such that not only is vibration reduced, but the amount of tooth face slip is also minimal to thus extend the lifespan of gears, and as deposits are discharged from the tooth faces through centrifugal force, they do not become lodged between the teeth. |
