1. Belts and Pulleys

2. Why Belts and Pulleys Transmitting power (long distances) Conveyer belts May simplify the cost and design of the machine Increase machine life (damping vibrations) Vacuum your floor

3. Types of Belts

4. ..And More Belts

5. Transmits up to 5000kW of power Flat Belts

6. Round Belts

7. Construction of Belts

11. Design Guidelines For Timing Belts Friction and Creep Tension Member Tensile Strength Flexibility Tooth shear strength

12. Tension Member Tensile Strength Allowable tensile load on belt cross section. Don’t forget about start up and acceleration.

13. Flexibility and Fatigue Drive without contraflexureDrive with contraflexure

14. Tooth shear strength The more belt teeth in mesh attainable, the better the load is spread. The shear strength calculation is based on the smallest pulley in the configuration.

15. Actual Load Distribution

16. Pulleys

18. All types Pick a pulley to match your belt Many types of materials (common: Aluminum, Steel, Nylon) Consider load requirements
