Selecting the right gears for heavy-duty industrial applications requires careful consideration of multiple technical parameters. As a leading industrial gear manufacturer with 9+ years of global export experience, YIZHI MACHINERY break down the key decision-making factors to ensure optimal performance and longevity.

1. Load Capacity & Torque Requirements

Why it matters: Underestimating load demands is the first cause of premature gear failure.

• Key calculations: Bending strength (ISO 6336)
  Surface durability (ISO 6336-2)
  Shock load tolerance (for crushers/mixers)
• Our solution: Custom tooth profile optimization to distribute stress evenly.

2.Material Selection

Common industrial gear materials comparison:

3. Precision Class (ISO 1328)

Accuracy requirements by equipment type:

• Conveyor systems: ISO 8-9
• Packaging machines: ISO 6-7
• Robotic arms: ISO 4-5

4. Lubrication & Maintenance Needs

Modern lubrication options:

• Oil bath: Traditional method for large gearboxes
• Grease-packed: For enclosed systems with <500 rpm
• Dry Lubricant: Food-grade applications (USDA/FDA compliant)

5. Environmental Conditions

Specialized solutions for harsh environments:

• High-temperature (≤300°C): Tool steel gears with molybdenum disulfide coating
• Wet conditions: Stainless steel and corrosion-resistant tooth profile
• Explosive atmospheres: Spark-resistant bronze alloys (ATEX certified)
