PURPOSE: A method for aligning the centers of bevel gears of an articulated robot is provided to measure the center lines of a pair of the bevel gears to set an accurate center point so that the bevel gears are engaged around the center lines and center point. CONSTITUTION: A method for aligning the centers of bevel gears of an articulated robot is as follows: A distance between the undersides of protrusions of a first jig and an outer housing(30) is measured, and a distance value of a center line of a first bevel gear(33) from the underside of the outer housing is set. A distance value of the center line of a fourth bevel gear(38) from a joined surface of protrusions of a second jig and an inner housing(31) is set. An intersecting point of the center lines of the first and fourth bevel gears is confirmed as a center point. A distance value of a center liner of a second bevel gear from the upper side of the outer housing is set. A distance value of the center line of a third bevel gear(37) from a joined surface of protrusions of a fourth jig and the outer housing is set. An intersecting point of the center lines of the second and third bevel gears is confirmed as a center point. A distance value of the center line of a fifth bevel gear(41) from a lateral side of the outer housing is set. A distance value of the center line of a sixth bevel gear(42) from the upper side of the outer housing is set as a center point. An intersecting point of the center lines of the fifth and sixth bevel gears is confirmed as a center point.
