6.3.2. Reducer

6.3.2. Reducer

 

Vibration and abnormal sound will be occurred when a reducer 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].

 

n Diagnostics

 

①    Check if there is vibration and abnormal sound during operation and also whether there is abnormal heating with the reducer during operation.

②    To see whether there is diversion and wear with the reducer, check if any abnormality can be felt, by holding the first arm and rotate the robot while the S axis brake release switch in [On] state.

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

(In some cases, the reducer may be damaged due to the shock from contact)

 

n Resolution

 

Replace the reducer. 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].

 

n Diagnostics

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

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

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

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

(Damage may occur to the reducer due to the contacting impact)

 

n Resolution

 

①    Replace the reducer.

②    Replace the entire wrist section.

(The replacement of entire wrist should be a quick and reliable resolution as it takes time and necessary equipment for reducer replacement)
