Specific Tension Ratio of V-Belt Drive

Click For Summary
SUMMARY

In V-Belt Drives, the Tension Ratio should not exceed 5:1 when installing a new belt. The Tension Ratio is defined by the formula T1/T2 = μ*α*cosecβ, where T1 and T2 represent the tensions, μ is the Coefficient of Friction, α is the Angle of Wrap, and β is the Groove Angle of the V-Belt. While these variables are constant for a specific drive, the actual tensions depend on factors such as power transmission, RPM, and pulley diameter. Understanding these dynamics is crucial for maintaining optimal performance and preventing belt slippage.

In a V-Belt Drive, it is said that when a New Belt is installed, the Tension Ratio shouldn't exceed 5:1. But isn't this ratio beyond control and is defined by T1/T2 = μ*α*cosecβ where T1/T2=Tension Ratio, μ=Coefficient of Friction, α=Angle of Wrap, β=Groove Angle of V-Belt. All of these variable are constant for a particular drive so how can a specific Ratio be maintained?

Your formula gives the maximum value of T1/T2 when the belt starts to slip.

The actual values of T1 and T2 depend on the power being transmitted be the belt, the RPM, the diameter of the pulleys, etc.
