A shaft directly coupled to a power source is called

Explanation:

Line shaft:

• A shaft directly coupled to a power source is referred to as a Line Shaft. This type of shaft is used to transmit power from the primary source to various machine components or systems in mechanical operations. The term specifically denotes the direct connection between the power source and the shaft, ensuring efficient power transmission without intermediate mechanisms.
• The Line Shaft operates by being physically connected to the power source, such as an engine or motor. This connection allows the rotational motion generated by the power source to be directly transmitted to the shaft. The shaft then distributes this mechanical energy to other connected components, such as pulleys, gears, or belts, which perform specific tasks or operations. Its direct coupling eliminates the need for secondary power transmission systems, enhancing efficiency and minimizing energy losses.

Applications: Line Shafts are commonly used in industries that require direct and robust power transmission systems, such as:

• Textile manufacturing units for operating multiple machines simultaneously.
• Conveyor systems in material handling processes.
• Machining operations in workshops and factories.
• Power transmission setups in agricultural equipment.

Important InformationCounter Shaft

• A Counter Shaft is used as an intermediate shaft in power transmission systems. It typically connects the main power source to other shafts or components, allowing for speed or torque adjustments.

Jack Shaft:

• A Jack Shaft is another type of intermediate shaft used in power transmission systems. It often serves as a connecting shaft between two main shafts or between the power source and the final driven component. Similar to the Counter Shaft, its function involves intermediate transmission rather than direct coupling to the power source.

Flexible Shaft

• A Flexible Shaft is designed to transmit rotary motion between components that are not perfectly aligned or have relative motion between them. It is commonly used in applications requiring flexibility in power transmission, such as handheld tools or equipment.
