The importance of RV Reducer Gear for industrial robots
The power source of an industrial robot is generally an AC servo
motor. Because it is driven by a pulse signal, the servo motor
itself can achieve speed regulation.
Why do industrial robots also need a speed reducer?
Industrial robots usually perform repetitive actions to complete
the same process; in order to ensure that industrial robots can
reliably perform process tasks in production and ensure process
quality, the positioning accuracy and repeat positioning accuracy
of industrial robots are very high. Therefore, to improve and
ensure the accuracy of industrial robots requires the use of RV
reducers or harmonic reducers.
Another role of precision reducers in industrial robots is to
deliver more torque. When the load is large, it is not cost -
effective to increase the power of the servo motor. The output
torque can be increased by the reducer in a suitable speed range.
In addition, servo motors are prone to heat and low - frequency
vibrations at low frequencies, which is not conducive to ensuring
accurate and reliable operation for long - term and periodic
industrial robots.
The presence of a precision reducer allows the servo motor to
operate at a suitable speed and accurately reduce the speed to the
speed required by various parts of the industrial robot, increasing
the rigidity of the machine while outputting greater torque.
Compared with universal reducers, industrial robot joint reducers
require short drive chains, small size, high power, light weight
and easy control.
