Analysis of Transmission Characteristic of Straight Bevel Gear and Zero Spiral Bevel Gear
Jixie chuandong, 2018 The finite element model of a pair of straight bevel gears is established,and the simulation is carried out by using the ANSYS/LS-DYNA software to verify the accuracy of the simulation method. Based on this,a pair of zero spiral bevel gears are created for comparative analysis.
