Precision gear is a kind of mechanical part. The teeth on it transfer motion and power through continuous meshing. The application of precision gear in transmission has long appeared. With the development of productivity, people pay more and more attention to the stability of precision gear. What are the main steps of gear design?

1. The driving power is calculated according to the load and the motion state (speed, vertical motion or horizontal motion)

2. Preliminary estimation of gear module (if necessary, gear strength verification can be carried out. If the module selection is too small, it is necessary to re determine the gear module. The selection of gear module is generally checked according to experience or reference analogy);

3. Carry out preliminary structural design, determine the total transmission and determine the transmission series (several levels of transmission)

4. According to the total transmission ratio, calculate the sub transmission ratio of each stage

5. Carry out detailed transmission structure design (detailed design of each shafting) according to the needs of the system, which is generally carried out on the general assembly drawing;

6. In the structural design, if we find that the early parameter setting is unreasonable (including excessive gears, mutual interference, manufacturing and installation difficulties, etc.), we need to return to the above program in time and start again;

7. Draw the schematic diagram of key shaft system (generally heavy-duty shaft), draw the curve diagram and torque diagram of each shaft end, find out the dangerous parts and check the strength of the shaft;

8. Strength check of low-speed shaft gear;

9. When no problem is found, split the part drawing.

The above is an introduction to the steps in the process of precision gear design. If you need precision gears, you are welcome to consult IHF Hefa gear manufacturer.
