A sheave wheel is a grooved wheel or pulley designed to hold a belt, rope, or cable. It rotates on an axle or bearing, allowing the rope or cable to move smoothly with minimal friction and wear
. The groove in the wheel keeps the rope securely in place while it moves. The primary function of a sheave wheel is to change the direction of the force applied to the rope or cable, making it easier to lift or move heavy loads. By redirecting the rope, it can transmit mechanical power, lift loads, and reduce the effort needed to move objects
. When multiple sheaves are combined in a pulley system, they create mechanical advantage, further reducing the force required to lift heavy weights. Sheaves are widely used in cranes, elevators, and various lifting and power transmission systems to ensure smooth operation, reduce wear on cables, and improve safety and efficiency
. They also help in transmitting rotary motion between shafts when used with belts, allowing control over speed and torque
. In summary, a sheave wheel is a grooved rotating wheel that guides and supports a rope or cable, changes the direction of applied force, and facilitates lifting or power transmission with reduced friction and mechanical advantage
