6.3.1. Reducer

6.3.1. 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     Investigate whether abnormal heat generation occurs in the parts that have a vibration or abnormal noise, as well as the reducer part, during operation.

②     In order to check for any clearance or wear on the reducer, hold the first arm and rotate the robot while setting the S axis bake release switch to the [ON] state and check if any abnormality is felt in your hand.

③     Check if the robot is in contact with peripheral devices before any abnormality occurs (The reducer can be damaged by an impact 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 motors off, with the brake release switch [ON], and checks 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)
