Application Overview
Purpose
- Operation
- There is a rack and gear set beneath the workpiece platform that allows it to advance faster as the cylinder pushes the gear forward.
Target workpiece
- Shape: block
- Material: tungsten
- Workpiece size: 50ｘ55ｘ90mm
Design Specifications
Operating Conditions or Design Requirements
- Cylinder advance stroke: 20mm
- Movable rack stroke: 50mm
- Outer dimensions: L244ｘW160ｘH102mm
Required Performance
- Load: 47N
Selection Criteria for Main Components
- Select wear resistant materials for the racks and pinion.
Design Evaluation
Verification of main components
- Confirmation of cylinder output
- Conditional Value
- When plant air pressure is 0.5MPa and cylinder inner diameter is 20mm,
Cylinder thrust (pushing side): 157N
Cylinder thrust (pulling side): 132N
Workpiece mass M₁ = 4.8kg, work table mass M₂ = 11.5N
Linear guide friction coefficientμ=0.005, gravitational acceleration g = 9.8m/s²
Cylinder stroke:st₁=20mm
Rack stroke: st₂=50mm - Work conservation law
- If we assume that the workload on the cylinder side and that on the rack side are the same,
Fc×st₁=F₁×st₂
Fc=F₁×st₂/st₁
Here, load applied by workpiece: F₁ is
F₁=(M₁＋M₂)×μ =(48+11.5)×0.005=0.30N
- Therefore, required cylinder thrust Fc is
-
- Conclusion
Other Design Consideration
- Select appropriate gear ratio to produce the desire additional speed.
