1. Calculate the drive power based on the load and motion state (speed, whether it is vertical or horizontal motion).
2. Preliminary estimation of gear module (if necessary, gear strength verification will be performed later. If the module is found to be too small during the strength verification, the gear module must be re-determined. The selection of gear module is generally based on experience or by analogy, and a safety verification will be performed later.)
3. Conduct preliminary structural design to determine the overall transmission and the number of transmission stages (how many stages of transmission).
4. Distribute the gears according to the overall gear ratio and calculate the individual gear ratios for each stage.
5. Conduct detailed transmission structure design (detailed design of each shaft system) according to system requirements. Such design is usually done on the assembly drawing.
6. If unreasonable parameters are found in the initial design (including excessively large gears, mutual interference, manufacturing and installation difficulties, etc.), it is necessary to return to the above procedure and start over in a timely manner.
7. Draw a simplified diagram of the critical shaft system (usually the heavy-duty shaft; of course, it's best to draw one for each shaft system), and draw the bending moment and torque diagrams for each shaft end to identify the critical sections and perform shaft strength checks.
8. Strength check of low-speed shaft gears
9. After confirming safety, disassemble the parts diagram.
