"Mechanical Beauty" to explore the robot components-precision reducer behind the story!

The sophistication of the modern industrial robots is amazing, in particular, the smart 5-axis 6-axis robot, with so many joints, but also able to do the precise movement and instruction transmission, the various parts close together to complete the complex work, people can not help but wonder what their transmission system is-you make, The precision reducer used in the joints of global robots is almost always made in Japan: The Japanese say kneeling, few of the world's robots can stand ...

In sci-fi illustrations, the robot's joint handling is always the key. In the 70 's Japan illustrator empty Mountain beauty Robot (184th phase) and human in addition to skin, the biggest difference is that in the joint joints with a large screw, think of various not feasible.

In recent years, in some of the robots (phase 124th) of the real-person model PS, the apparent division and mechanical structure of the joints can be observed.

Speaking of joints, mainly refers to the most important industrial robot basic components, but also the core components of the movement: precision reducer. This is a precise power transmission mechanism, which utilizes the speed converter of the gear, reduces the number of revolutions of the motor to the desired number of rotation, and obtains a larger torque device, thus reducing the rotational speed and increasing the torque.

At present, the world can provide large-scale and reliable performance of precision reducer production enterprises are not much, the vast majority of the global market share is occupied by Japanese enterprises: Nabtesco RV reducer accounts for about 15% of 60%,harmonica harmonic reducer, as well as Sumitomo Heavy Industry (SUMITOMO, Proportion not found). Especially in the field of robotics, the proportion of applications is overwhelming. This issue is about the top two.

Nabtesco Precision Reducer

Nabtesco (Nabotsk) was founded in September 2003 and looks like a 00-post company. In fact it is by the Emperor Spermatogonial Machine (Teijin seiki,1944) and Nabock (nabco,1956 years of production of Japan's first automatic door) These two Japanese companies combine powerful merger. As a manufacturer of motion control systems and components, the two companies have mastered high-end core technology in their specific business areas, controlling a high market share, so Nabtesco Fu was the first in the same industry in Japan and the world. Most robot manufacturers around the world benefit from Nabtesco's patented RV reducer and bring success.

As the world's largest manufacturer of precision cycloid gear reducer, Nabtesco produces high-performance reducer, hollow shaft reducer, and single axle servo actuator and controller. Its production of precision equipment with high torque, high rigidity and high resistance to overload impact load capacity, with high precision and very low return clearance.

Nabtesco has a few small videos that visually visualize its products on a variety of industrial robots. Mechanical June grilled to one of the 6-axis robot to share with you.

Each joint needs to use a different reducer product

1944 Dili Spermatogonial Machine set up at the beginning of the aircraft industry to carry out business, 1947 into the textile machinery manufacturing sector, 1955 began to manufacture aircraft parts, 1959 expanded to machine tool manufacturing. Nabtesco RV Reducer, the predecessor is Dili spermatogonial machine mainstream products, the 70 's began as a mining equipment drive motor core components used. In the early 80, at the request of the world's major robot manufacturers, Dili Spermatogonial Machine improved RV reducer, making it more accurate and reliable, in line with the requirements of the robot manufacturing industry. After the patent of the precision cycloidal Wheel RV reducer was made, the mass production began in 1986, and the joint application of modern industrial robot was set up.

Nabtesco various Reducer

Technology Dismantling

The line can be conveniently passed through the hollow part of the reducer. This design not only has greater torque, compression ratio, close to 0 backlash, but also loads a larger set of internal angle support shafts that provide greater momentum and dispense with external support equipment. This leads to further savings in cost and simplifies the design of end users.

Application areas

Nabtesco is committed to becoming "the world's leading aerospace, land and marine equipment movement control systems and related components of the expert", their equipment can upgrade from the satellite, radar antennas, industrial robots, semiconductors and welding technology, such as industrial automation in the field of many applications of product capabilities.

Harmonic Drive reducer (harmonic drive)

The harmonic drive reducer (harmonic gear drive) is a gear transmission system which can control elastic deformation of flexible gears and engage with rigid gears and transmit movement and power from the beginning. The harmonic drive reducer was made by the American Clarence Walton Musser (1909~ 1998-06-08) in 1957 by the invention patent (US Patent number 2906143), in addition to The longevity inventor, who worked in the Pentagon for 15 years, has 250 major inventions in his life, such as military recoil rifles, aircraft catapults, underwater explosion test instruments, and so on.

Sounds like a big industry category, in fact Harmonic Drive is the trademark of Harmonic Drive BAE Inc. 1960 USM Company First Harmonic Drive reducer successfully put into use, later Hasegawa Gear Co., Ltd. (Hasegawa Gear Works, Ltd.) Obtained the production license of USM. October 1970, Hasegawa and USM each contributed 50%, in Tokyo, the establishment of Harmonic Drive Bae Inc., translated into Hamenaco. Eight a gua: Hasegawa when President name Tanigawa Gear car, mechanical June think this name is destined to do gear ...

Hamenaco is the leader of the overall movement control, its production of harmonicdrive harmonic reducer, with light weight small, no gear gap, high torque capacity and so on, is widely used in industrial robots, humanoid robots, semiconductor liquid crystal production devices, photovoltaic equipment, optical instruments, Precision machine tools and other cutting-edge fields.

January 1, 2006 Hamenaco and Nabtesco's U.S. subsidiary in Massachusetts established a joint venture harmonic Drive L.L.C.

Basic

In order to cover the harmonic reducer can not be achieved in the field of low deceleration ratio, the product also involves precision planetary gearbox-type harmonic reducer (Harmonic planetary). The unique deformation process of the inner ring can make the planetary gears more compact and eliminate the backlash, which has reached the precision-level transmission error.

Benign competition or herd

We've all heard a classic joke:

There was a Jew at the gas station, and the second point was to open the physical store, and very lucrative, the third Jew opened a car wash shop and very lucrative, the fourth person opened what other services, finally became more and more famous, and finally someone opened a big school there, someone opened a post office or something, finally there is very rich.

Changed the Chinese, the first man opened a gas station, the second on the side hurriedly opened a gas station, the third to see money and opened a gas station, finally, everyone to showmanship desperate price promotions, and finally most of the losses, drubbing and return, but also survive a big injury.

Similar cases we hear countless, internet innovation is the same, Peer-to-peer herd, the public to raise herd, someone to make a game to make a horse game, Ma Yun do taobao in full swing, immediately out of a pile of shopping malls, Ma Yun did the balance treasure out a pile of treasure ... Once each industry began to benefit, there must be a large number of people herd, soon the entire industry into the shuffle of the bloody scuffle.

And the Jewish way of thinking is cooperation and borrowing power, always rush to each other to drive the popularity and flow, complementary direction, in another field to create new opportunities.

With the rapid development of the economic transformation and the aging process of China's population, the development of the robot industry ushered in a stage of rapidly developing demand. According to robotics industry research expert ROB, 2013 China market sales of industrial robots nearly 37,000 units, accounting for about 1/5 of global sales, total sales surpassed Japan, ranked first in the world. China is expected to become the world's largest robotic market in 2016, with more than 150,000 units. Even Nabtesco plans to invest nearly 5 billion yen in a new factory in China, starting from 2016 to produce the core components of industrial robots, with plans to produce 100,000 units per year and 200,000 units in 2020.

The higher profits of robots induce an unprecedented upsurge of enthusiasm in the domestic manufacturing industry, and the competition is becoming fiercer.

Since the world's first two rival companies are cooperating, domestic enterprises and their herd head-on, leading to all-out vicious competition, as meditation, like the Japanese, efforts to find their own unique advantages and direction, specializing in a few points miles? From point breakthrough, benign competition, work together, the road is wider, go longer ha
