The … WebApr 2, 2014 · Frequency is defined as Hertz (Hz) [cycles / sec.]. For the gear meshing it can be calculated by number of teeth * rotational speed [rpm] / 60. Gear meshing frequency is a harmonic phenomenon and its harmonics can be found by multiplying fundamental meshing frequency by whole numbers (1, 2, 3…). 2 / 10
WebGear Forces. When the gear mesh transmits power, forces act on the gear teeth. As shown in Figure 12.1, if the Z-axis of the orthogonal 3-axes denotes the gear shaft, forces are defined as follows: The force that acts in the Y … WebMar 17, 2024 · The gear mesh frequency, or GMF, is calculated by multiplying the number of teeth on a gear by the shaft speed: GMF = (shaft speed) x (# of teeth) Because gearbox shafts are linked together by design, we can then relate input and output speeds based on the number of teeth using a second equation:
