Detailed explanation-1: -Shafts. A mechanical shaft is a mechanical power transmission element that conveys power and rotational motion from one device to another.

Detailed explanation-2: -Power transmission device The power transmission apparatus is all components of the mechanical system which transmit energy to the part of the machine performing the work. These components include flywheels, pulleys, belts, connecting rods, couplings, cams, spindles, chains, cranks, and gears.

Detailed explanation-3: -transmission, in mechanical engineering, a device interposed between a source of power and a specific application for the purpose of adapting one to the other. Most mechanical transmissions function as rotary speed changers; the ratio of the output speed to the input speed may be constant (as in a gearbox) or variable.

Detailed explanation-4: -Mechanical power transmission involves using different types of systems to transfer energy from one component to another without changing its nature. When motion coming from a driving mechanical component is transferred to another without being changed, there is power transmission.

Detailed explanation-5: -5. Gear drives. Though a gear drive is used to transmit torque or power from one shaft to another, just like other drives, they are also often used to change the rotation direction or the movement angle. Additionally, gear drives are used to increase or decrease the torque and range of speed.
