The height of the tooth above the pitch line. Dedendum (hf): The depth of the tooth below the pitch line. 3. Force and Torque Analysis
To begin any calculation, you must define the basic parameters of the gear (pinion) and the flat gear (rack).
The diameter of the pitch circle on the pinion. Number of Teeth (z): The count of teeth on the pinion gear. 2. Core Calculation Formulas rack and pinion calculations pdf
The distance between corresponding points on adjacent teeth.
This is the clearance between mating teeth. For high-precision CNC machines, "zero-backlash" or split-pinion designs are often required. The height of the tooth above the pitch line
You need 300mm of travel per pinion rotation. Determine Pitch Diameter: Choose a Module: If you select Module 2, then Adjust to Whole Teeth: Round to 48. Your new becomes 96mm. Calculate Final Travel: per revolution.
Use the Lewis Formula to calculate the bending stress on the teeth to ensure the material (steel, nylon, brass) can handle the load. Force and Torque Analysis To begin any calculation,
The distance the rack moves per one full revolution of the pinion.
