PURPOSE:To reproduce large shocking torque in a laboratory by providing an exciting device on a supporting part of one gear device, and imparting a static load to a supporting part of another gear device. CONSTITUTION:In an exciting device B, a bolt 19 is provided in the following manner: one end of the bolt 19 is attached to a position which is separated from the center of rotation of a disc 18 by a distance (y); while the other end is supported with an attaching part 5a of a gear case 5 through an elastic body 15; the other end of the bolt 19 is fixed to the attaching part 5a with a nut 14. The disc 18 is supported on a supporting stage 20 so that the disc 18 can be rotated. A pulley 21 is coaxially provided with the disc 18. A belt 24 is hooked on a pulley 23 which is attached to a power source 22 in a coaxial pattern and the pulley 21. When vibration having a displacement + or - (y) is imparted to the side of the attaching part 5a of the gear case 5, i.e. a small gear, a repeating load acts on the gear case 5. When a static load is made to act on one gear device under this state, the normal load and the vibrating load can be loaded on the gear case. |
