Step 1
Motion requirement
- Travel, speed and acceleration
- Continuous and peak linear force
- Duty and direction changes
- Accuracy, repeatability and holding load
Step 2
Rack drawing
- Module/DP, pressure angle and spur/helical hand
- Body size, material, hardness and finish
- Mounting holes, datum and straightness
- Segment joints and pitch matching
- Dust, mud, fertilizer, wash and lubricant
Step 3
Installation and inspection
- Pinion support, mesh adjustment and guarding
- Tooth thickness, pitch and cumulative pitch
- Mounting datum and joint matching
- Backlash along full travel
