Types Of Mechanical Power Transmission

There are diverse types of mechanical power transmission that you can use in various industries for efficient power supply. Below are the most famous:

Gear Drive

Gear drive transmission processes consist of two or more toothed wheels that are connected to work together for efficient transferring of mechanical power within a short distance while maintaining a steady velocity ratio. In addition, this transmission process is often put into consideration when there is a need for substantial power transmission.

Advantages	Disadvantages
Gear drive does not slip because it has high efficiency.	Gear drive requires regular lubrication.
There is solidness which guarantees a long life span.	The gears used to mesh requires an actual alignment.
They are the most suitable for high mechanical power transmission.	Gears do not have flexibility.
It’s compact, and it transmits motion in short spaces.	It is more expensive.

Belt Drive

Belt drive power transmission process is a way whereby powers are being transmitted by a consistent moving flexible belt. Furthermore, this means that there’s mechanical power transfer from one shaft to another through the flexible belt that runs over two pulleys. In conclusion, The pulleys rotate at the same or different speed for the rotary motion to be able to transmit power from the driving pulley to the driven pulley.

Advantages	Disadvantages
Affordable.	There’s a tendency of the belt slipping off the pulleys.
Absorbs shock and vibration.	The belts does not last
It does not need lubrication.	Short lifespan
Belt drive transmits power from long distances.	Limited speed range

Chain Drive

Chain drive makes use of chains to transfer mechanical power from one driving shaft to the other. In addition, the chain drive is made of a series of pin-jointed links that are covered by two or more sprockets. In conclusion, for the mechanical power to be transferred, there’s a need for mechanical force, and the chains have to wrap around the shaft sprocket.

Advantages	Disadvantages
Chain drive do not slip	They vibrate sometimes and are noisy.
One chain drive will power a variety of shafts at once.	Some require constant lubrication.
Torque can be transferred from long distances.	There is often a need for chain readjustment.
It’ll tolerate high driving force	They usually need enclosure.

Power Screws

Power screws help to convert rotary motion into a linear movement. In addition, they have nuts and screws that are mesh together for power transmission.

Advantages	Disadvantages
Power screws can lift heavy loads.	Poor efficiency
The operation is smooth and quiet.	High wear rate
There’s no need for too much maintenance.	Power screw is not recommended for high torque mechanical power demand
They are cheap and reliable.

Shaft Coupling

Shaft coupling is the type that connects two mechanical components i.e drive shaft and driven shaft in a motor for energy transmission to take place. In addition, the shafts are often intersecting but not parallel, and they are produced in varieties for the needs of every application to be met.

Advantages	Disadvantages
Low maintenance cost	The drive components can damage when some coupling loose over time.
Absorption of vibration and shock	It tolerates small angular misalignment.
It isolate heat	No mechanical fuse feature.
Shaft coupling withstand radial and axial misalignment

Advantages Of Mechanical Power Transmission

There is assurance of efficient power transmission.
The energy transmission process is versatile.
It is autonomous i.e it depends on itself to generate energy.
Easily accessible.
It speeds up the transmission process.
Mechanical power transmission affects the transmission process positively by reducing manual labor.

Elements Of Mechanical Power Transmission

Shaft: Transmits power and rotary motion from one place to another.

Coupling: It connectS the ends of two shafts for efficient transfering of angular rotation and torque.

Power Screw: Connects elements in the process of transmitting power in technological products.

Gear Trains: They’re‘ set of multiple gears that helps to transmit power.

Brakes And Clutches: They help the shaft to move at different speeds in a common axis of rotation.

Chains: Support the transmitted torque.

Why Is Mechanical Power Transmission Needed?

There are various reasons for the need of mechanical power transmission, some of which include:

For converting generated energy into useful form.
For changing speed and torque direction
For changing rotational energy to linear energy

Applications Of Mechanical Power Transmission

The applications of mechanical power transmission is important to successfully transmit power in different industries.

Automotive Industries	Mechanical power transmission in the automotive industry gives control over the speed, torque, and directional of the conveyed force.
Aerospace	It is used by aircraft and spacecraft to control gear and landing surface.
Renewable Energy	Turbo and hydropower systems utilize power transmission to convert rotational motion into electrical energy.
Rail Transportation	It can be use for propulsion and breaking down systems in trains and locomotives.

Conclusion

In conclusion, mechanical power transmission is important for efficient transmitting of energy without having to go through a lot of hurdles as it saves time and human effort.
