Harmonic reducer is a low-speed and high-torque transmission equipment. The small gear of the input shaft meshes with the large gear on the output shaft for harmonic transmission, so as to achieve the purpose of deceleration. However, for how to calculate the speed ratio of the harmonic reducer, Everyone knows less. How to calculate the speed ratio of a harmonic reducer Harmonic reducer reduction ratio calculation formula: Reduction ratio = motor output revolution ÷ harmonic reducer output revolution Harmonic reducer torque calculation formula: Torque=9550×motor power÷motor power input revolution×speed ratio×use efficiency The calculation formula of the gear ratio of the harmonic reducer: Gear Ratioⅰ = Number of teeth of large gear/number of teeth of small gear The number of teeth of the rigid wheel of the harmonic reducer is generally 2 teeth more than that of the flexible wheel. When the wave generator is installed in the inner circle of the flexible wheel, the flexible wheel is forced to continuously deform, so that the teeth of the two wheels are engaged, meshed, and meshed. In the process of exit and disengagement, the working status of each is constantly changed, resulting in the so-called staggered tooth motion, which realizes the motion transmission between the active wave generator and the flexspline, thereby achieving a large speed ratio.
