Abnormal noise
◼
Abnormal noise occurs after
changing grease
◼
Abnormal noise occurs when
the robot is put into operation after
long-time shutdown
◼
Abnormal noise occurs during
low speed operation
1.The manipulator has abnormal
noise at low operation speed
immediately after replacement or
upon restart after long-term
shutdown
1.Observe the operation of the
manipulator for 1-2 days. Usually
the abnormal noise will disappear
Shaking of
manipulator
◼
After cutting off the power of
the manipulator, shake some parts
of the manipulator by hand
◼
There is a gap in the joint
surfaces of the manipulator
1.The manipulator bolts are loose
2.It may be because some
connection
bolts
on
the
manipulator are loose due to
overload or collision, which causes
the shaking
Check whether the bolts in the
following parts of the axes are
loose, and if yes, tighten them at
an appropriate torque with a
torque wrench.
1.Motor fixing bolt
2.Reducer housing fixing bolt
3.Reducer output shaft fixing bolt
4.Base fixing bolt
5.Inter-arm fixing bolt
6.Housing fixing bolt
7.End actuator fixing bolt
◼
Cut off the power supply of the
manipulator, and after checking
that the screws are tightened,
shake the whole head of the
manipulator by hand.
1.It may be because the internal
gear of the manipulator is worn or
damaged due to overload,
collision, having a wide backlash
1.If you want to replace the
internal gear, please contact the
company
Motor overheating
◼
The
temperature
in
the
manipulator
installation
environment rises, and the motor
overheats
◼
The motor overheats after a
cover is installed on it
◼
The motor overheats after
changing the operation program
and load conditions of the
manipulator
Ambient temperature:
1.After the ambient temperature
rises or the motor cover is
installed, the heat dissipation of
the motor deteriorates, which
causes the motor to overheat
Load action:
It may be because the motor
current value exceed the rated
value due to the load and
operation program
1.Reduce
the
ambient
temperature, which can effectively
prevent the motor from being
overheated
2.Improve
the
ventilation
conditions around the motor, and
that is, the heat dissipation of the
motor, which can effectively
prevent the motor from being
overheated
3.When there is a heat source
around the motor, a radiation
shielding plate can be provided to
effectively prevent the motor from
being overheated
4.Through slowing down the
operation program and reducing
the load conditions, the average
motor current value will be
