The importance and applications of harmonic reducer gerabox
1.Brief of harmonic reducer gearbox
A harmonic reducer gearbox, also known as a harmonic drive, is a type of high-precision gearbox that uses elastic deformation to achieve a high reduction ratio in a compact design. It's characterized by its ability to provide high torque, high precision, and smooth motion with a compact structure. It achieves speed reduction and torque amplification through the deformation of a flexible gear (flex spline) within a rigid circular spline.
2.Working process of harmonic reducer gearbox
1.Deformation:The wave generator rotates, causing the flexspline to deform into an elliptical shape.
2.Meshing:The flexspline's teeth engage with the circular spline's teeth at the points where the ellipse is widest.
3.Relative Rotation:As the wave generator continues to rotate, the points of engagement between the flexspline and circular spline move around the circumference. Since the circular spline has more teeth than the flexspline, the flexspline rotates relative to the circular spline, resulting in a speed reduction.
4.Output:If the circular spline is fixed, the flexspline's rotation drives the output shaft, providing a high-reduction ratio.
3.Importance of hamonic reducer gearbox
1.The harmonic drive gear ratio is large. Single-stage harmonic gearing transmission speed ratio range from 70 to 320, in some devices, can reach 1000, and multi-stage transmission speed ratio up to 30,000 or more. It can be used not only for deceleration but also for speed-increasing occasions.
2.It has a high load-bearing capacity. This is because the number of teeth engaged at the same time in the harmonic gearing transmission, the number of teeth engaged at the same time in the double-wave transmission can reach more than 30% of the total number of teeth, and the flexible wheel is made of high-strength materials, and the teeth and teeth are in contact with each other.
3.High precision harmonic transmission. Because the number of teeth meshed at the same time in the harmonic gear transmission, the error is averaged out, so that multiple teeth meshing has a mutual compensation effect on the error, and the transmission accuracy is high. In the case of the same gear accuracy level, the transmission error is only about 1/4 of the ordinary cylindrical gear transmission.
4.Harmonic drive gearbox has high efficiency and smooth motion. Since the teeth of the flex wheel make uniform radial movement during transmission, the relative slip speed of the teeth is still extremely low even if the input speed is high. Therefore, the wear of wheel teeth is small and the efficiency is high (up to 69%~96%). And because of the meshing and meshing out, both sides of the gears are participating in the work, so no impact phenomenon, smooth movement.
5.The structure of the harmonic drive is simple, the number of parts is small, and it is easy to install. There are only three basic components, and the input and output shafts are coaxial, so the structure is simple and easy to install.
6.It is small in size and light in weight. Compared with a general reducer, the volume of the harmonic gear reducer can be reduced by 2/3 and the weight by 1/2 when the output torque is the same.
7.Harmonic gearing can transmit motion to confined space. Using the flexible characteristics of the flexible wheel, the wheel transmission is incomparable to other transmissions.
4.Main applications of harmonic reducer gearbox
1.Robotics:Harmonic drives are crucial for robotic arms, manipulators, and other robotic systems, enabling precise and smooth movements necessary for tasks like assembly, welding, and material handling.
2.Aerospace:The high power-to-weight ratio and reliability of harmonic drives make them suitable for satellite systems, space telescopes, and other aerospace applications.
3.Industrial Automation:In automated manufacturing processes, harmonic drives are used in CNC machines, packaging equipment, and other machinery requiring accurate and repeatable movements.
4.Medical Equipment:Harmonic drives are found in surgical robots, diagnostic equipment, and other medical devices where precision and reliability are paramount.
5.Precision Measurement Instruments:Their high accuracy and low backlash make them ideal for optical measuring instruments, coordinate measuring machines, and other precision testing and measurement devices.
6.Semiconductor Manufacturing:Harmonic drives are used in wafer handling robots, lithography equipment, and other semiconductor manufacturing processes where precise positioning and repeatability are critical.
7.Printing and Packaging:In printing presses and packaging machinery, harmonic drives ensure accurate registration, consistent speed control, and precise movements.
