6.2.2 Timing Belt Replacement
The timing belt is used in the robot for the driver system of the J5 and J6 -axis. Although
the belt tension has been adjusted before the robot delivery, the timing belt will wear depending
on the working conditions. The belt tension might be lower than the standard after operating
for a long time. The timing belt should be periodically checked, maintained and replaced.
(The belt replacement of RA610-GB and RT610-GB are the same. The following figures only
show the belt replacement of RA610-GB.)

Timing Belt replacement period
When the maintenance time is up to (six month), check the belt tension. If the tension is
insufficient, adjust the belt tension. If the belt is excessively worn (wearing about half of the
tooth width), the belt tooth is cracked or the belt is broken, replace the belt, but you are required
to re-origin the points to correct the points.

Belt Tension
It is very important to keep proper belt tension. The belt tooth jumping will happen if the
belt tension is too loose. If the belt tension is too tight, it will cause damage to the motor or
bearing. Measuring methods of the belt by using fingers or tools are shown in Figure 6-2. The
sonic tension meter is used to measure the belt tension. The specifications and standard tension
of belt are shown in Table 6-4.

When replacing the belt, the robot system origin
may deviate. In this case, the position data must be
rechecked if the origin is offset. (Refer to section
4.1)

It is normal that the belt produces debris during
operation, but if it happens right after cleaning the
belt, it is recommended to replace the belt.
