Long Life >6000hrs RV Gearbox RV-27C-36.57, RV Hollowshaft
Cycloidal Gear Reducer
RV gearbox has small volume, large reduction ratio, low working
inertia, low noise, high torsional rigidity, high impact load
resistance (can withstand 5 times rated torque), high working
precision (backlash less than 1arcmin) and long service life. The
technical level is domestically leading and internationally
In 2010, we developed for high - end industrial applications
(industrial robots) transmission core components RV gearboxes and
series AC servo motors, and put into mass production, which has
been widely recognized in the market. In 2013, the output was more
than 200 units.
We has successfully developed RV gearboxes for robots under 300 kg,
with a total of 17 products.
E series RV-20E, RV-40E, RV-80E, RV-110E, RV-160E, RV-320E, RV-450E
C series RV-10C, RV-27C, RV-50C, RV-100C, RV-120C, RV-200C,
And RD series RD-20E, RD-50C.
ABB is also our customer, ABB has purchased the our RV-50C products
in batches for automated production lines, and has accumulated no
more than 15 months of performance problems.
RV gearbox features & applications
Less than 1 arc - min Backlash, strong impact resistance, very
compact with high torsional rigidity, component in - line version
for greater design and space saving flexibility, large transmission
ratio range, high transmission efficiency, long working life.
Application to high - end intelligent equipment industry such as
industrial robots, external shafts, precision machine tools,
radars, and medical devices.
RV gearbox noise and lifttime
1. The gear reducer is operated at rated speed with a noise of <
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.
