5.3.3 Inspection, maintenance and replacement of timing belt

This robot uses a timing belt for the drive conveyance system of the J5 axis. Compared to gears and chains, the

timing belt does not require lubrication and has a low noise. However, if the belt usage method and tension adjust

-

ment are inadequate, the life could drop and noise could be generated. Sufficient aging to remove the initial elon

-

gation of the belt, and adjustment of the belt tension have been carried out before shipment from the factory.

However, depending on the robot working conditions, elongation will occur gradually over a long time. The tension

must be confirmed during the periodic inspection. The timing belt must be replaced in the following cases.
In addition, it is serviceable if there is the sound wave type belt tension gauge in inspection and adjustment of the
timing belt. The recommendation gauge is shown below. Please prepare by customer. Refer to the

Timing belt tension"

for the tension adjustment value of the timing belt.

Maker:Gates Unitta Asia Company,
Type:U-505

(1) Timing belt replacement period

The timing belt life is greatly affected by the robot working conditions, so a set time cannot be given. However, if

the following symptoms occur, replace the belt.

1) When cracks from at the base or back of the belt teeth.
2) When the belt expands due to adherence of oil, etc.
3) When the belt teeth wear (to approx. half of the tooth width).
4) When the belt teeth jump due to belt teeth wear.
5) When the belt snaps.

Due to the manufacturing of the timing belt, initial wear will occur. Wear chips may
accumulate in the cover after approx. 300 Hr of operating the robot, but this is not a
fault. If the wear chips appear soon after wiping them off, replace the belt.

When the belt is replaced, the machine system origin may deviate. In this case, the
position data must be reviewed.
