PROBLEM TO BE SOLVED: To provide a gear coupling that can reduce maintenance man-hours at the time of failure of a component.SOLUTION: A gear coupling 10 according to the present invention comprises: sleeves 12a and 12b in which internal gears 11a and 11b are formed on the inner periphery; and hubs 14a and 14b that are arranged inside the sleeves 12a and 12b and in which external gears 13a and 13b are formed on the outer periphery. The internal gears 11a and 11b are engaged with the external gears 13a and 13b. In the gear coupling 10, the strength of the hubs 14a and 14b is made lower than the strength of the sleeves 12a and 12b. |
