Through big data modeling, simulation optimization and performance verification, Han's Motion team realizes the optimal design of tooth profile, breaks through barriers of experience accumulation and correction in transmission design, and continuously improves and innovates in the parameter performance, product structure, processing technology, material and appearance of harmonic drive actuator. Through long-term technical experience, Han's cheap harmonic drive has improved in product accuracy, service life, stability, noise control and some other key technologies have reached the highest level in the world, and the technical indicators are in the forefront. At present, Han's harmonic drive has independently developed and produced 11 product series and more than 300 harmonic drive and newly upgraded to high torque series, which improves product accuracy and service life, reduces vibration and noise, with more stable and reliable performance. Our harmonic drive covers the intelligent manufacturing industry and are widely used in aerospace, communication equipment, robots, semiconductor processing equipment, medical equipment, testing and analysis equipment and other fields. Harmonic Gear Transmission Principle The harmonic gear drive was invented by an American inventor, C· W· Musser. user in 1955, It is a new type of transmission, which uses the elastic deformation of flexible components for motion or power transmission. It breaks through the mode of using the rigid component to realize mechanical drive, but with a flexible component instead, thus obtaining a series of special functions that other transmissions cannot reach. Its name comes from the deformation process of the intermediate flexible component, which is a symmetrical harmonic. Except that the former Soviet. Union called this kind of transmission"Wave Transmission" or "Flexible Gear Drive", other countries like America, England, Ger many, and Japan all called it "Harmonic Drive'. Harmonic Gear Deceleration Principle The principle of harmonic drive china transmission deceleration is to use the relative motion of the flexible gear, rigid gear, and wave generator (mainly the controllable elastic deformation of the flexible gear), to realize the motion and power transmission. The elliptical cam in the wave generator rotates in the flexible gear, causing the flexible gear to deform. When the flexible gear teeth and the rigid gear teeth at both ends of the long shaft of the elliptical cam in the wave generator enter the engagement, the flexible gear teeth at both ends of the short shaft are disengaged from the rigid gear teeth. For the teeth between the long shaft and the short shaft of the wave generator, the half meshing state that is gradually entering into the meshing along the different parts of the circumference of the flexible gear and the rigid gear, is called meshing and the half meshing state that is gradually disengaging is called engaging-out. The continuous rotation of the elliptical cam in the wave generator makes the flexible gear deform constantly, which causes the teeth at the flexible gear and rigid gear to shift between the states of engaging-in, meshing, engaging-out, and disengagement, thus realizing motion transmission from active wave generator to the flexible gear. The Composition Of The Harmonic Gear Assembly Rigid gear: A rigid internal gear, usually 2 teeth more than a flexible gear, usually fixed onto the case; Flexible gear: Thin-cup metal elastic part with gears on the outer ring of the opening part. It deforms with the rotation of the wave generator and is usually connected to the output shaft; Wave generator: Consisting of an elliptical cam and a flexible bearing, usually connected with an input shaft. The inner ring of the flexible bearing is fixed on the cam, and the outer ring can be elastically shaped into an ellipse through the ball bearing. Harmonic Drive Wiki With the rapid development of artificial intelligence, the artificial labor in many areas are now replaced by robots. Although the cost of robot is very high, it has created huge benefits for enterprises. Not only saves labor greatly, but also works efficiently. The wide use of industrial robots can not only improve the quality and capacity, but also be of great significance to ensure personal safety, improve the working environment, reduce labor intensity, improve labor productivity, save raw material consumption and reduce production costs. Planetary Gear Set In recent years, as long as we talk about industrial robots, they will connect to the harmonic reducers. The industrial robot industry chain can be divided into core parts, manufacturing, and system-integrated application. Among them, the core parts are the basis of robot development and cost up to 72% of the total cost of the robot. And the most important is the precision china harmonic reducer (mainly harmonic drive and RV Reducer) which cost accounts for 36%. Harmonic gear drive reducer is widely used in the field of industrial automation because of their small volume, light weight, large torque, compact installation, large transmission ratio, and high transmission accuracy. At present, with the rapid development of industrial automation, the demand for harmonic reducers has also increased a lot, and the supply continues to exceed the demand. Right Angle Gearbox Han's Motion is also one of the manufacturers engaged in the R & D and production of Harmonic Drive. At present, its products are at the forefront of China manufacturers. It has independently developed 12 product series and 300 + harmonic drives, which have been widely used in the automation industry. Over the past few years, this small but very important parts for the robot, account for about 30% of the total cost of the robot. The cost accounts for the highest proportion of all key parts. However, the development in China is not so smooth. The reducer is called "nail house" and "big trouble" in the development of domestic robots. Moreover, foreign brands almost occupy the high-end application field, and the development of domestic robots still has a long way to go.
