Design elements of rack and pinion

Design elements of rack and pinion

1. Determine the module according to the rack and pinion load

2. The number of teeth of the gear is initially determined according to the limitation of the rack and pinion structure, thereby determining the diameter of the gear

3. Refine the design of the installation of the rack and pinion

4. Consider whether a limit device should be installed at the extreme positions of the rack and pinion. If it is electric, a travel switch should be added, and if it is manual, a limit backing (also called a backing block) should be installed.

5. Consider rack and pinion lubrication

6. Consider whether the backlash between the gear and the rack needs to be pretended to be an adjustment device (generally not)

7. Consider the safety protection in the operation of the rack and pinion, mainly the safety protection of people
