Design elements of rack and pinion
1. Determine the module based on the gear and rack load.
2. Based on the limitations of the gear and rack structure, the number of teeth of the gear is initially determined, thereby determining the diameter of the gear.
3. Refine the design of gear and rack installation
4. Consider whether limit devices should be installed at the extreme positions of both ends of the gear and rack. If it is electric, a limit switch should be added; if it is manual, a limit stop (also called a stop block) should be installed.
5. Consider gear and rack lubrication
6. Consider whether a backlash adjustment device is needed between the gear and rack (generally not).
7. Consider safety precautions during gear and rack operation, primarily focusing on human safety.
