Calculation Procedure
- 1
Enter pulley diameters and center distance.\n2. Select belt type (flat or V-belt).\n3. Review belt length, wrap angle, and tensions.\n4. Adjust center distance if wrap angle is too low.
Practical Engineering Application
In mechanical power transmission, accurate belt drive sizing prevents slip and premature wear.
✓ Design Checklist
- • Verify wrap angle >= 120 deg
- • Check belt velocity limits
⚠️ Common Pitfalls
- • Ignoring V-belt groove angle in tension ratio
