Industrial robots Bearing Research and Application
First, the development of industrial robots bearing
Industrial robots Industrial robots bearing as one of the key supporting parts in China is still a weak link. Existing bearings can not meet national standards and guidance of industrial robots bearing design, production and testing. In order to break this bottleneck, the company over the years, access to a lot of relevant information, to understand the internationally renowned manufacturer of industrial robots bearing related products and standards, through repeated trial process in a large number of experimental data obtained on the basis of the formation of their own corporate standards, bearing in robot design, process principles, inspection standards, technical standards and other aspects have gained a breakthrough, through the "introduction - imitation - digestion and absorption - innovation" course.
Currently, Wei Sige Luoyang Bearing Co., Ltd. has become the only professional production of industrial robots bearings.
So, what is the industrial robot bearing it Called industrial robots bearings, mainly include two categories of bearings for industrial robots, one thin section bearings, etc., and the other is a cross cylindrical roller bearings. Another harmonic reducer bearings, linear bearings, spherical plain bearings, etc., but mainly the first two bearings. Thin section bearings such as shown in Figure 1, it is a seven open series, five series consisting of thin-walled bearing seal family. Open series of three types: radial contact, angular contact type and point contact type.
Seal Series There are two types: radial contact-and four-point contact type. And other thin section bearings and plain bearings are different, this type of bearing cross-sectional dimensions in each series is designed to be a fixed value: namely 0.1875X0.1875 inches, 0.25X0.25 inches, 0.3125X0.3125 inches. 375X0.375 inches, 0.50XO. 50 inches, 0.75X0.75 inches and. OXl. 0 inches: In the same series cross-sectional dimension is constant, it does not change with diameter size increases, so called thin-section bearings, etc.. Using large bore, small cross-section of thin-walled bearings, you can use a large diameter hollow shaft instead of small diameter solid shaft, so as: air, light, water pipes, cables, etc. through the hollow shaft of space to offer, to make the design more simple.
Use of thin section bearings, you can save space, reduce weight and significantly reduce friction and provide good rotation accuracy. In weight of the host, can be downsized. Figure 2 is a cross bearing cylindrical roller bearings.
Its structure is characterized by: cylindrical roller bearing inner and outer Yuangun tract arranged perpendicularly intersecting each other. Single bearing can withstand the radial force, bi-axial force and overturning moment together. Bearing capacity, good rigidity, high precision turning, easy to install. Cross cylindrical roller bearing products structure: the overall type, outer-and inner separation separation type. For anti-pollution and anti-spill needs, you can install both sides of the bearing seals.
Both of these bearing its unique light structure and good performance, simplify design, save space, the robot joints and rotating unit, precision turntable and aerospace and other fields are widely used. To facilitate industrial robots bearing production series, we have designed a cross-section of industrial robots and other thin-walled bearing samples, light cross cylindrical roller bearing samples developed technical standards, and by experts, Quality and Technical Supervision for the record, to fill the domestic blank. The technical standards with international standards.
After years of research and development, the company now has three types of bearings such as thin-walled section 12 series products, companies were identified as high-tech enterprises, in 2005 by Luoyang Municipal Science and Technology Progress Award, 2006 by the National Science and Technology identified for the national Torch Program project undertaker, when the State Development Fund to support innovative SMEs, respectively, in 2004, in 2007 passed the radius Certification Center, China quality certification, ~ IS09001: 2000 quality management system certification.
Second, industrial bearings robot applications
Our company produces brands such as Wei Sige thin section bearing, cross roller bearings, the existing production capacity of 20,000 units / year, mainly exported to North America, Europe, South Korea, Singapore and Taiwan and other countries and regions, for a price , stable quality, fast delivery praised by users and praise, six years have not happened with the quality of questioning and return events. Bearing Inspection Center of the State, Wei Sige bearings and abroad the same type and size, same accuracy class bearings contrast, the overall level is very, some items better than imported bearings, fully able to meet user needs.
These bearings are mainly used in machinery exports of arms, semiconductor processing equipment, glass grinding machine, beverage filling machines, automatic cameras and other fields. Domestically, the company has increased in recent years, market development efforts, has for the CAS Shenyang Institute of Automation, Electronics Technology Group Corporation, Shijiazhuang 54, Harbin Institute of Technology, Shanghai University, aerospace five homes, Shanghai Hua Wei, Zhejiang Hengfengtai, Kunshan, China Constant and other research institutes, universities, enterprises are provided for research, such as import substitution cross section thin-walled bearings and cylindrical roller bearings, used in good condition, orders increased. May 2002, Shanghai Printing Co., Ltd. Huawei Li body imported from Japan a model TOKIC0700-146T dyeing robots, by the end of 2005, due to the robot using a set of lumbar Japan THKRB40035 bearing damage, downtime repairs. They order the Japanese side, was told to wait a long time, the price is expensive, and repair parts will be several years after discontinuation. They "Robot Technology and Application" magazine that Wei Sige bearing information, then to my company for help. In early 2006, the company for supporting the four sets of CRB40035/P5 class bearings (Figure 3), a replacement immediately resume normal use of the machine, the machine 24tJ ~ when continuous operation, has running in good condition, very satisfied users.
May 2007, we Kunshan Hua Heng Engineering Center Co., Ltd. developed welding robot provides three cross cylindrical roller bearings and two kinds of sealed thin wall bearing (Figure 4), when the assembly is named Kunshan, on the 1st of welding robot after debugging, smooth and reliable operation, CCTV evening news programs have done coverage. Currently, there are two welding robots have also been assembled, working with universities and research institutes to work together on improving the software part. Zhejiang Hengfengtai reducer company is a private enterprise, they wear gold Anshan Anshan Institute of synthesis and production of wear-resistant metal CORT precision reducer, mainly for robots, remote control devices, aerospace instrument devices and various requirements of high precision transmission The automatic control system. The product has received at the Geneva World Invention and New Technology, and China National Invention Exhibition Gold Award, is the world's most advanced precision mechanical transmission equipment, our company with such precision reducers for supporting thin-section bearings. Figure 5 is a company many times for the national key scientific research projects to provide high-precision, high reliability specialty thin-walled bearings.

Three, drip proposal
At present our company in the domestic market sales to total sales ratio less than 10%, we can see a huge market prospects China Robot. Japan since the 1970s, after the first global oil crisis, in order to improve the car industry's competitiveness in the international arena, with a 15-year period, so that Japan's industrial robots surpassed the United States as the world's production and application of industrial robots. " kingdom. " Korea in the late 1980s, took 10 years to form its own industrial robot system, now South Korea's automobile and electronics industries domestic robots large number of applications and have a full set of Korean auto welding robot production line into China. China from the 1980s, for continuous invested several hundred million dollars of funds, spent nearly 20 years, but so far not even one able to mass production with Chinese enterprises own intellectual property rights of industrial robots are not established, the gap is very large. We in the field of robotics industry development Why so slow Insight said: mainly due to the overly academic, there is no production capacity. We call a number of years "production, learning and research," the slogan of the combination just lip service, not put into action. Sitting pontificating, with little success. Flap National Conference made it clear that companies in technological innovation has played the main role should be, which is 20 years behind in exchange for a consideration of experiences and lessons learned.
It should be noted that the main business is not dominant, but can not go it alone. Our technological innovation system should be: this historic enterprise technological innovation of the project, it should be the backbone of that body; universities and research institutes are nerves and blood; national authorities of the brain and the soul, play a leading role guide research units work together, to work effectively, so as to form a strong overall vitality. Personally think that the state should seriously study and develop policies and take measures to solve the "repeated introduction, the introduction of" the chronic illness, out of the "introduction - backward - and the introduction - and then backward" this historical cycle, abandon the "introduction of wing, to the use of domestic equipment ashamed "misconceptions overcome in the" introduction - digestion - absorption - re-innovation "in the" self-enclosed, self-blockade, arrogant, "the drawbacks, advocates and even mandatory to give companies domestic innovative products provide a platform to give preferential treatment on taxes. For example, we can demand but some dependence on imported equipment, products, technology bidding held by the government-sponsored enterprises and efforts, research and technological forces. Such countries can gradually reduce the import of products.
In the future introduction, we dare, can not say: "I'll introduce this set will not import the second set, the second must be made in China!" This is a national self-reliance, self-reliance, self-confident spirit embodied I look forward to that day, looking forward to a group with independent intellectual property rights of Chinese enterprises to establish and develop industrial robots, industrial robots in the world, a place on the stage.
