Strong Impact Resistance RV Gear Reducer RV-C Precision Cycloidal
Gear RV-200C -34.86
Accuracy 1μm RV gear reducer
The robot RV precision reducer, commonly known as "robot joint", is
the core transmission component of high - end automation equipment
represented by industrial robots. In the field of global industrial
robot core components, the Japanese reducer brand Nabtesco has long
occupied 60% to 80% of the international market share of precision
reducers for industrial robots.
Nantong Zhenkang is the first company in China to overcome the
technical difficulties of RV reducer and realize mass production.
It integrates independent design, processing and assembly.
1) Strong detection capability, high - precision Zeiss three -
coordinate, gear detector, bearing detector, profilometer, finish
meter, industrial computer. The current detection capability of
Zhenkang has reached the national professional testing room testing
2) Everyone knows that the precision of the parts is 2μm, and the
precision of the tooling cannot exceed 1/3 of 2μm. In order to
ensure the accuracy of the tooling, Zhenkang not only purchased the
thousand - level Xia Mier wire - cutting machine, Swiss grinding
machine, etc., but also modified the special machine tool and
independently developed and manufactured the bearing. At present,
the self - made bearing precision is stable at P4 level, and some
reach P2. level. High - precision machine tools are developed or
modified by themselves, achieving an accuracy requirement of 1μm.
3) Zhenkang's production workshop, each station is using a large
amount of dust - free paper. Every time the worker uses dust - free
paper, the parts and tooling are wiped clean before the clamping
process is performed to ensure each part of the reducer. All are μm
- class precision. Under this precision requirement, any dust and
iron filings that are invisible to the naked eye will affect the
accuracy of the parts and the whole machine.
4) In the testing room, a variety of testing equipment and parts
are arranged neatly, and each part or machine corresponds to at
least one test report.
Each part undergoes rigorous testing before entering the next
process, and each machine undergoes rigorous testing before it
leaves the factory.
It is not difficult to achieve a precision of 1μm. It is difficult
to achieve 1μm at any position of 360 degrees. Only precision,
stiffness, noise, backlash, transmission efficiency, temperature
rise... all meet the standard is a qualified reducer. ZKRV is such
a qualified RV reducer.
Features of RV gear reducer
- 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
- Large transmission ratio range.
- High transmission efficiency.
- 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.
To ensure the accuracy and longevity of the gear unit, please
replace the grease after every 2000 hours of operation.
- The gear unit is operated at rated speed with a noise of < 75
The noise level is related to installation accuracy, lubrication,
temperature, load and other factors.
