Nabtesco RV Gear Reducer , Cyclo Speed Reducer 35.61 Reduction Gear Ratio

Product Specification

RV Gear Reducer RV-320C-35.61 to Repalce Nabtesco RV Series Robot Arm Gear Reducer

RV gear reducer description

The robot reducer generally uses a harmonic reducer and an RV reducer (ie, a cycloid reducer) .
RV reducer is the core transmission component of industrial robot. It has small size, light weight and high rigidity, is resistant to overload, and has the characteristics of rotating vibration and inertia. Therefore, the acceleration performance is good. It can be used smoothly on the robot to achieve smooth operation and accurate. The positional accuracy, which accounts for nearly half of the cost of the entire robot.

For 20 years, Nantong Zhenkang has been focusing on the development and production of the core components of precision robots, precision motors and precision reducers, from the beginning of the printing motor, to the later wire feeders and automated welding trolleys, to the current RV reducers. In 2010, it developed the RV reduction gear for industrial robot transmission core components and series AC servo motors, which have been put into mass production.

Zhenkang has the most comprehensive RV reducer comprehensive performance test platform, which can quickly and effectively measure RV reducer backlash accuracy, transmission accuracy, efficiency, noise, stiffness, vibration and other performance indicators. The RV reducers produced must pass the detection of the backlash accuracy, noise and stiffness, and the products that meet the enterprise standards can be shipped.

Features of RV gear reducer

1. Less than 1 arc - min Backlash.
2. Strong impact resistance.
3. Very compact with high torsional rigidity.
4. Component in - line version for greater design and space saving flexibility.
5. Large transmission ratio range.
6. High transmission efficiency.
7. Long working life, the gear reducer is operated at rated conditions with a life of > 6000 hours. It is not advisable to operate for longer than the rated speed or rated torque, otherwise the life will be reduced.
8. To ensure the accuracy and longevity of the gear unit, please replace the grease after every 2000 hours of operation.
9. The gear reducer is operated at rated speed with a noise of < 75 dB, the noise level is related to installation accuracy, lubrication, temperature, load and other factors.
