Mechanical Power Transmission System। Advantage And Disadvantages Of Them।

Mechanical Power Transmission System.


This content is about Mechanical Power Transmission System Or Energy TransferAdvantage And Disadvantages Of Mechanical Power Transmission System Or Energy Transfer. The factory or industry requires driving power to run various machines. The various machine’s required motives have to be transferred from one place to another place. Or the power has to be increased or decreased or needs to torque converter. The process by which the power of a machine is transferred or decreased or increased is called a transmission system. Here we will discuss Mechanical Power Transmission Systems Mechanical Energy Transmission Systems Or torque converters. 

Mechanical power is usually transferred to the factory in the following ways. V-belt, Gear, and Coupling transmission systems are the most commonly used of the following methods. These are discussed. Such as

  • Friction Wheel,

  • Flat Belt,

  • Synchronized Belt,

  • V-Belt,

  • Round Belt, 

  • Chain,

  • Gear,

  • Coupling.



What Is A V-Belt?

V-Belt sits in the V group of Puli called Siv. The number of this group can range from one to 15 depending on the transfer of power. The v-belt is made with several layers of rubber. Rubber consists of cotton reinforcement cord, plastic, and sometimes thin steel along its v-belt neutral axis. The v-belt is prepared in different grades and dimensions without end.


The v-belt dimension is expressed as follows.

Largest Width  X  Height  X  Inner Length.


What Are The Advantages And Disadvantages Of A V-Belt Compared To Other Belts?

The advantages of the V-Belt among other mechanical power transmission belts are discussed below. The v-belt has more advantages than other comparative belts and is more used in industry for comparatively long life-timers. 


  • More power can be transferred through a V-Belt.

  • The slip of percentage is too low.

  • This drive is soundless and the vibration is low.

  • The V-Belt drive is very effective for nearby safety.

  • Less tension causes less friction on the bearings of the V-Belt drive.

  • The V-Belt never loosens or moves away from the pulley.


  • If any one of the accidents breaks, all the belts have to be replaced again.

  • V-Belt speed is lower than the flat belt.

  • It is difficult to open sideway the V-Belt as it sits in a group.

  • The V-Belt easily breaks overload.

The pulley speed of the drive needs to be measured occasionally while moving to get better mechanical power transmission through the V-Belt. This allows the slip of the belt to be measured. The sound of belts and puli must be observed at all times. Since loose will create unusual sounds. Occasionally belt vibrations need to be checked while running. The alignment of the belt and puli needs to be checked when stopping condition. Whether the driving and driven shaft parallels are ok can be seen in the off-state. 


What Is A Gear?

Gear transmission systems are used for the percentage of slip-free, powerful power transmission and high power transfer between nearby shafts. The following gear transmission systems are most commonly used in industries.

  • Spare Gear,

  • Helical Gear,

  • Herringbone Gear,

  • Bevel Gear,

  • Warm Gear,


What Is A Spare Gear?

Advantages And Disadvantages Of A Spare Gear.

A disc (gear wheel) consists of a number of teeth parallel to the axis or shaft along its circumference. The Spare Gear is the largest useable gear in mechanical power transmission systems or mechanical energy transmission systems.  


  • The spare gear is more effective than any other type of belt.

  • It is convenient to use A Spare Gear for low RPM.

  • Spar gear’s lifetime is longer and maintenance is much easier.


  • Spar gear is louder.

  • Too much noise is felt at high speeds and comparative jerking loads.

  • Run the gear in a lubricating oiled or lubricant-oiled container.

  • 1 out of 2 spare gears (usually pinion) is made of a non-metallic material such as synthetic, resin, or plastic).

  • Using helical gear.

What Is A Helical Gear?

Advantages And Disadvantages Of A Helical Gear.


Helical gears consist of teeth located angularly with the axis around the circumference of the wheel of the gear.


  • Noise is less than spare gear because a time multiple teeth work together.

  • Since the teeth of the helical gear are longer than the teeth of the spare gear, the teeth of the helical gear of the same thickness are stronger.

  • Helical gear is less vibrating than spare gear.


  • The helical gear always generates an axial force.

  • The result is thrust along the axial.

  • Additional thrust bearing or herringbone gear is required to withstand this axial force.


What Is A Herringbone Gear?

The herringbone gear is generated by combining the teeth of two sets of reverse helical gears on the same gear wheel. Since the two gears balance each other, the problem of helical gears does not exist in herringbone gears. Herringbone gears are commonly used to transfer large amounts of power.

Preventive Protection Measures In Moving Condition.

  • Regularly the vibration of the gearbox is measured.

  • You need to pay attention to the gearbox.

  • The temperature and vibration of the bearing should be monitored.

  • Need to monitor the temperature of the gearbox.

Preventive Protection Measures In Stop Condition.

  • Gear teeth need to be checked.

  • If any tooth decays or breaks, the gear should be changed.

  • The back of the gear should be measured to see if it is within that limit.



Since it is not possible to run a mill machine without Mechanical Power Transmission Systems Or Mechanical Energy Transmission Systems. So Mechanical Power Transmission Systems Or Mechanical Energy Transmission Systems need to be monitored routinely. You need to try to run the machine or factory properly. For this, you must check the machine letter in the form of a daily weekly, and monthly drawing routine. We have to take action accordingly.
