RV-80E Rv Reducer Gear Long Working Life, Same as Nabtesco Gearbox
RV-80E is widely used in welding positioners and on
turntables.
As the joint of industrial robots, the RV reducer is the most important basic component of the robot and the core component of the sport. This is a sophisticated power transmission mechanism.
The RV reducer is mainly composed of a cycloidal wheel, an
eccentric shaft and a pin gear shell. It has the characteristics of
compact structure, large transmission ratio, low vibration, low
noise and low energy consumption. The development trend of the
reducer for industrial robots is high - speed deceleration ratio,
small volume, high load capacity, high efficiency and long service
life.
The reducer has a great impact on the performance of industrial
robots, especially in the robots with high precision requirements,
which mainly provide three performances.
1. Increase the torque: The reducer can double the torque of the
motor output when the overall space of the robot arm is limited.
2. Increase the resolution: Effectively reduce the minimum
displacement that the load can move, and increase the resolution
accuracy.
3. Enhance the ability of the motor to withstand the load inertia:
The proper inertia ratio between the motor and the load enhances
the performance and stability of the system and minimizes power
loss.
RV precision reducer is widely used in the arm joints of industrial
robots to complete precise operating procedures. At the same time,
it also has the function of supporting the strength of the robot.
Its high rigidity and high reduction ratio are now widely used in
six - axis vertical joints. The first three axes of the robot. In
addition, in the use of automation equipment, the precision reducer
has the characteristics of high precision, high efficiency, high
rigidity, small size, light weight, large range of reduction ratio
and long service life. In addition to industrial robots, the
application fields can be used in precision transmissions such as
semiconductor production equipment, precision instruments, machine
tools, precision radar drive control equipment, and solar equipment
that require small space and large reduction ratio. RV reducers
have been widely used in heavy - duty and high - precision robots.
