Rigid Construction RV Gear Reducer RV-27C-36.57, Same As Nabtesco Cycloidal

Our RV reduction gear reliability, have a long lifetime and precision, less than 1 arc - min backlash, very compact with high torsional rigidity, in - line version for greater design and space saving flexibility, integrated Angular bearings for large thrust & overhung moment capacity, high ratio availability up to 1/212, without increasing gearbox size, torque capacity up to 5X rated torque (E - stop), 100% continuous contact of the cycloidal pin & gear teeth design provides high shock load capacity and very low backlash since forces are distributed throughout the reducer, 2 - stage reduction structure reduces vibration due to the lower speed rotation of the two cycloidal gears, special input shaft design lowers inertia.
One of the most critical mechanical structures of industrial robots is the RV reduction gear, 38% for the RV reducer, at present, 75% of the precision reducers in the global robot industry are monopolized by Nabtesco and HarmonicDrive in Japan (commonly known as RV reducers and harmonic reducers in the industry), including the reducers of international mainstream robot manufacturers such as ABB, FANUC, and KUKA provided by the company. Nabtesco's RV reducers account for about 60%, and Harmonica's harmonic reducers account for about 15%.
In the past 20 years, we has been focusing on the development and production of robotic precision motors and precision reducers. In 2010, we developed RV gear reducers for industrial robot transmission core components and series AC servo motors, which have been put into mass production.

RV reduction gear noise and lifetime

1. 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.
2. 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.
To ensure the accuracy and longevity of the gear unit, please replace the grease after every 2000 hours of operation.
