Robots have always been called "the top jewel of the manufacturing crown". Today, robots have been widely used in various industries and engaged in various jobs.
This is due to countless engineers and scientists tirelessly creating, improving, and in some cases redefining robotics. "Precision reducer" is one of the most critical and core parts of the robot.
SZLD Harmonic Drive Technology Group was established in 1991. Since its establishment, it has been focusing on the development of precision transmission devices such as harmonic reducers. After years of hard work and independent research and development, SZLD has taken the lead in mastering the core technology and realized the harmonic reducer Completely independent production is of great significance to promoting the independent development of China's domestic robot industry. In August 2018, SZLD was listed on the Shanghai Stock Exchange.
On October 16, SZLD held a 2020 new product launch. Professor Ding Han, academician of the Chinese Academy of Sciences, Song Xiaogang, executive chairman of the China Robot Industry Alliance, and more than a dozen top industry experts, as well as nearly a hundred domestic and foreign SZLD customers, came to the scene and witnessed SZLD has entered a new stage.
Breaking the monopoly, DNG flexible bearing new product release
At the site SZLD also released three new products at the same time, namely DNG non-fatigue flexible bearings, "Tornado" series rotary actuators and edge management system, demonstrating strong continuous research and development capabilities.
Zhang Yuwen, deputy general manager of SZLD, first introduced the first new product-DNG non-fatigue flexible bearings to the audience. Zhang Yuwen emphasized that DNG flexible bearings came from customer needs. Initially, in order to meet the high speed and high response requirements of SCARA robots, they obtained inspiration and innovation breakthrough points from SCARA robots with fast speed, short acceleration and deceleration time, and overload requirements. After in-depth analysis After a lot of tests, Green Harmonic found that under the same load conditions, the SCARA robot harmonic reducer flexible bearing inner ring receives more impacts than other operating conditions, and the impact load is greater. Inner ring fatigue is its service life. Short board.
Therefore, in view of the mechanism and characteristics of the fatigue failure of the inner ring of the flexible bearing, SZLD adjusted the alloy element ratio of the bearing material through long-term exploration and research, and adopted a new heat treatment and strengthening process to manufacture the latest fatigue-free DNG flexible bearing. The DNG flexible bearings are more impact resistant and have a longer service life.
It is worth noting that, in order to verify the reliability of the product, SZLD has undergone a lot of tests and comparison experiments. By simulating the running state of the SCARA robot, the SZLD series reducer using DNG flexible bearings was compared with foreign competitors under the same nearly 3 times load and motor acceleration test conditions of 6000r/min. After thousands of hours, the flexible bearings were analyzed and compared. It was found that SZLD's DNG flexible bearings are significantly better than those of well-known foreign brands in harmonic reducer, regardless of surface fatigue, subsurface fatigue or near-surface fatigue.
Data and experimental results also prove that SZLD's latest DNG flexible bearing has undergone a large number of performance tests and bench tests. After over-speed, overload, and long-term operation, there are no fatigue cracks on the surface and subsurface of the inner ring of the bearing. It is a fatigue-free bearing. It shows the excellent impact resistance, fatigue-free and long life performance of DNG flexible bearings.
Powerful Cyclone series rotary actuator
Subsequently, Dr. Chu Jianhua, general manager of JSKX Intelligent Technology Company, a subsidiary of SZLD, also released the second innovation for intelligent equipment—the cyclone series rotary actuator.
The Cyclone series rotary actuator is the result of more than 3 years of polishing and exploration of new directions by dozens of R&D teams. It integrates a special high-performance harmonic reducer, low cogging torque and high power density frameless torque motor, etc. And special vibration and noise reduction design, successfully realized low vibration, low noise, low temperature rise and smooth control, the absolute positioning accuracy is up to 10 arc seconds, the rigidity is increased by 2 to 3 times than similar products, but it can achieve The output torque is from 10N·m to 1470N·m.
Not only that, with the optimized design of highly integrated mechatronics systems such as low-voltage and high-current bus-type servo drives, high-precision photoelectric encoders, ultra-thin electromagnetic brakes, and smart sensors, the Cyclone series rotary actuators also have fast response and long life. , Zero backlash, large aperture, high protection, maintenance-free, tolerance of extreme ambient temperature and many other advantages, successfully applied to semiconductors, medical equipment, laser processing, CNC machine tools, factory automation and many other fields.
