Figure 1
Table 11: Conveyor Belt Speed Factor
Belt Speed Calculation:
How to Calculate Belt Speed
1. Determine gearmotor RPM from tables 2-9.
2. Determine the pulley kit ratio. Count the number of teeth on the drive and driven pulleys following figure 1. Using table
10, look up pulley ratio based on pulley combinations.
3. Determine conveyor speed factor using table 11. Based on your conveyor type, select the appropriate factor.
4. Calculate belt speed:
Example: Belt Speed = Gearmotor RPM (tables 2-9) x Pulley Kit Ratio (table 10) x Conveyor Speed Factor (table 11)
2200 Series parallel shaft DC variable speed 20:1 gearmotor with 44 tooth sprocket on gearmotor (Drive) and 28 tooth
