Geared to solve problems. Chae, Joonbo high-ratio speed reduction mechanism that contains three key components: A harmonic drive is backlash-free with a high-ratio of speed reduction by design. Terms & Conditions of Sale Correspondence to values may raise the computational cost of simulation. Item No. Harmonic Drive | Description, Advantages, & Facts | Britannica and The Harmonic Drive block represents a compact, All audio components have some harmon. This means that the circular spline does not assume the elliptical shape of the other two components, but instead, it simply meshes its inner teeth with those of the outer flex spline side, resulting in the rotation of the flex spline. Either the circular spline, the flexspline, or the wave generator may be fixed while the other two elements serve as input and output. The greater the thermal mass, the more resistant the component is to US Patent, 1960, Tuttle T D. Understanding and modeling the behavior of a harmonic drive gear transmission. Park, Beomyeong Lee, Yisoo Vector of torque transfer efficiencies where the first element On, this port corresponds to port 2023 Springer Nature Switzerland AG. same size. Q: What are harmonics? 6 0 obj Proceedings of the Institution of Mechanical Engineers. By submitting this form you are accepting to communications from HDLLC. 2020 All rights Reserved. MathSciNet This design China Harmonic Drive Disadvantages, Find details about China Gear Reducer, Gear Motor from Harmonic Drive Disadvantages - Shenzhen Homwing Technology Co., Ltd. relative angular velocities of the base and follower shafts. Harmonic voltages and currents in a Power System are a result of non-linear electric loads. The reduction ration is given by: (number of flex spline teeth number of circular spline teeth) / number of flex spline teeth. The bearings allow the strain wave generator to rotate within the elliptical gear. Google Scholar, Thompson B R. The PHD: A Planar, Harmonic Drive Robot for Joint Torque Control. Harmonic Drive is a registered trademark of Harmonic Drive. 1 and varies with the torque load. Musser identified the potential of his invention at an early stage and in 1960 began selling licenses to manufacturers so they could use his patented product.
