6.3.2. Reduction Gear

Vibration and abnormal sound will be occurred when a reduction gear is damaged. In this case, it causes overload and abnormal deviation disturbing normal operation. Sometimes overheating may result. The robot may also become completely immovable, or a position offset error may occur.

[Main Axes (S, H, V)]

When turning [ON][OFF] the brake release switch of axis H and axis V, be sure to take necessary precautions to prevent the ARM from dropping, and then switch the brake release [ON][OFF]..

￿Diagnostics

①Check out any vibration, abnormal sound or overheating of the reduction gear when the robot is in operation.

②Check out any play and abrasion in the reduction gear. And check if any abnormality is felt by hand when shaking 1st ARM back and forth with the brake release switch of axis S [ON].

③Check if peripheral equipment has been contacted with the robot before the abnormality.

(Damage may occur to the reduction gear due to the contacting impact.)

￿Resolution

① Replace the reduction gear. A chain block is needed to lift and hang the robot ARM. Contact our service office for any difficulties.

[Wrist Axes (R2, B, R1)]

When turning [ON][OFF] the brake release switch, be sure to take necessary precautions to prevent the ARM from dropping, and then switch the brake release [ON][OFF].

￿Diagnostics

①Check out any vibration, abnormal sound, or overheating of the reduction gear when the robot is in operation.

②Check out any play in the reduction gear by shaking the End Effector (such as spot gun and hand devices, etc.) back and forth.

③Turn motors off , with the brake release switch [ON], and check that the axis can be rotated by hand. If not, the reduction gear is in bad condition.

④Check if peripheral equipment has been contacted with the robot before the abnormality.
