Gear design steps

Gear design steps:

Determine the gear ratio according to the motion transmission chain;

According to the torque acting on the pinion, calculate the circumferential force Ft acting on the gear teeth (radial and axial forces are useful for calculating the strength and stiffness of the shaft);

Based on the minimum number of teeth without root-cutting, determine the number of teeth of the pinion of a reasonable gear;

Selection of gears Material and heat treatment;

Calculate the gear module by the design formula of bending fatigue strength of gear teeth;

Calculate the gear indexing circle diameter by the design formula of contact fatigue strength of gear teeth;

According to the calculations, determine the modulus of the gear and the indexing circle diameter and the width of the gear;

Determine the gear geometric parameters and dimensions (including the gear shifting parameters);

Determine the gear geometric parameters and dimensions (including gear shifting parameters);

From the tooth contact fatigue strength calibration formula and tooth contact fatigue strength calibration formula, calibration calculation of the gear, if necessary, also need to carry out the calculation of tooth resistance to gluing ability;

Gear structure design to determine the lubrication mode of the gear drive;

Completed.
