Where should a V-belt primarily ride in the groove of the sheave?

The V-belt should primarily ride high in the groove of the sheave. This position is crucial for several reasons.

First, when the belt is positioned high, it is better aligned with the sheave, which helps in maximizing the effective contact surface area between the belt and the sheave's sides. This alignment is essential for optimal power transmission, reducing slippage and wear on both the belt and the sheave.

Secondly, riding high in the groove allows the belt to take advantage of its design, which is made to fit snugly against the sides of the sheave. This snug fit creates higher friction, leading to improved grip and efficiency as the belt drives the attached machinery or system.

Additionally, operating in this position helps maintain tension in the belt, which is important as loose belts can lead to decreased performance and increased wear and tear over time.

In summary, for effective operation, power transmission, and longevity of both the V-belt and the sheave, a high position within the groove is optimal.
