Helical gear calculations5/23/2023 ![]() Helical gears can mesh in one of two ways. ![]() Because of this, the contact line between the two teeth is not parallel to the axis, and the teeth gradually mesh, making the gear run smoothly. ![]() Helical gears are similar to spur gears the only difference is that the teeth are cut at an angle to the axis. The profile of the gear body is modeled by a mathematical model used to calculate the kinematics of the gear. In the helical gear, the bearing stiffness is 6.84 x 107 N/m, while the plate damping is 2,040 kg/m2s. The linear motion equation determines the axial excitation force in the rotational direction with a damping coefficient of 0.07. Helical gears have two essential characteristics: axial excitation force and circumferentially curved contact planes.
