RV Reducer Gear development history
1. 1926 German Lorenz Brown explains the principle of RV reducer
creatively.
2. In 1931, Lorenz Brown created the "Segule" Co., Ltd. in Munich,
Germany, and first started the manufacture and sale of cycloidal
speed reducers.
3. In 1939, Sumitomo Corporation of Japan and the "Secule" company
signed a technical cooperation agreement, and production and sales.
4. In 1944, the Japanese Teijin Seiki was established. This future
RV reducer overlord has achieved fruitful results in many
industries such as aircraft manufacturing, textile machinery and
machine tools.
5. From 1950 to 1960, the appearance of the cycloidal grinder
solved the problem of the low precision of the cycloidal tooth
shape, and the cycloidal transmission was further developed.
6. In 1956, Nabok Japan released the world's first automatic door,
which made its mark on the market.
7. Around 1980, the Japanese Teijin Seiki introduced the RV
transmission theory and began to apply it to the industrial robot
industry.
8. In 1986, the Japanese Teijin Seiki RV reducer was officially
mass - produced and succeeded.
9. In 2003, Teijin Seiki and Nabok merged to form Nabtesco and
achieved rapid development. Now it has become the leader of the RV
reducer industry, occupying more than 60% of the market, especially
in China. On heavy - duty industrial robots, its RV reducer market
share is as high as 90%.
In 2010, Nantong Zhenkang Welding Electromechanical Co., Ltd (our
cooperative partner) was developed for high - end industrial
applications (industrial robots) transmission core components RV
reducer 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.
RV Reducer Gear 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 Reducer Gear noise and lifttime
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.
