How To Increase the Efficiency of the Machine By Maintaining The Lubrication

When we are talking about how to increase machine efficiency with the help of proper lubrication, we should first understand machine efficiency. The efficiency of a machine indicates how well and how much input energy is converted to useful output energy or work. It is a major factor in the usefulness of a machine and is the fraction or percentage of the output divided by the input.

What causes the efficiency of a machine to be less than 100?

Friction affect the efficiency of a machine. When there is a relative motion between two objects, friction happens. Friction is the resistance to motion. And the best way to reduce friction is to use lubrication. Due to friction, machine efficiency reduces. Suppose you find a type of sliding surface that does not generate friction during relative motion; then there is a chance to get 100% efficiency. But these types of sliding surfaces are not available who do not generate friction during relative motion. Friction between two sliding surfaces, prevents machines from being 100% efficient.

How To Increase the Efficiency of the Machine?

Applying oil, grease, or any lubricant to machines reduces the friction between the moving parts and thereby increases the machine’s efficiency. The energy that is lost as heat due to friction is reduced.

What becomes of energy when efficiency is lowered in a machine?

Due to friction, the machine’s efficiency reduces and heat is generated. Heat is also a kind of energy. The heat dissipates into the environment, and it is a complete loss. That’s how heat energy generated by friction is lost when efficiency is lowered in a machine.

How can the efficiency of a simple machine be increased?

The efficiency of a simple machine can be increased in two ways.

  1. Using a lesser Coefficient of Friction metals for relative sliding motion into the machine.
  2. Usage of best lubricant, which reduces the friction at the optimum level.

1) Using a lesser Coefficient of Friction metals for relative sliding motion into the machine.

When we are talking about the lesser Coefficient of Friction metals, you should know more about the Coefficient of Friction. Here is the list of coefficient of friction for several combinations of materials in a dry and clean state:

  • Steel – PTFE – 0.04
  • Steel – Graphite – 0.1
  • Steel – Phosphor-bronze – 0.35
  • Steel – Cast iron – 0.4
  • Steel – Acrylic – 0.4 – 0.5
  • Steel – Copper – 0.53
  • Steel – Brass – 0.51
  • Steel – Tungsten carbide – 0.4 – 0.6
  • Steel – Aluminum – 0.61

For other pairs of materials:

  • Zinc – Cast iron – 0.85
  • Copper – Cast iron – 1.05
  • Copper – Glass – 0.68
  • Glass – metal – 0.5 – 0.7
  • Diamond – metal – 0.1 – 0.15
  • Wood – metal – 0.2 – 0.6

For material to same material:

  • Steel – 0.80
  • PTFE – 0.04
  • Glass – 0.94Aluminum – 1.35
  • Copper – 1.0
  • Iron – 1.0
  • Silver – 1.4
  • Zinc – 0.6
  • Glass – 0.9 – 1.0
  • Diamond – 0.1
  • Polystyrene – 0.5
  • Nylon – 0.15 – 0.25
  • Wood – 0.25 – 0.5
  • BAM (made of boron, aluminium and magnesium) – 0.02

2) Usage of best lubricant, which reduces the friction at the optimum level.

As we have already discussed, lubricant reduces the friction generated between two sliding surfaces. That is why we usually apply lubricants between the moving parts. Also, lubricant helps to reduce the heat generated due to friction and helps to increase the machine’s overall efficiency. Hence, the proper lubricant, like oil or grease, and the proper lubrication method can help increase a simple machine’s overall efficiency.

If any machinery or transmission needs periodic and regular lubrication what is the best method to give it?

Every running machinery or transmission in this world needs periodic and regular lubrication with proper lubricants to reduce friction and increase the machine’s overall working efficiency. If you want to know more about the best lubrication methods available, you can go through the detailed article on best lubrication methods. Normally there are two types of lubrication methods available.
1) Manual Lubrication Lubrication Method
2) Centralized Lubrication Method.

Is it right that better lubricants lead to better machine performance?

Yes. This is right that better lubricants lead to better machine performance. Not every lubricant is made for every application. When you dig deep into the lubrication and tribology industry, In that case, you will know thousands of lubricants are available as per the different application criteria and application requirements.

Before choosing the right lubricant for any application, one should check the four mentioned criteria.

1) Speed of the application
2) Ambience of the application, For example, Wet or dusty ambience.
3) Load of the application.
4) Temperature of the application or at the lubrication point.

What are the advantages of lubrication?

Lubricants play different vital roles when applied in an application, and below are the advantages of lubrication.

The most important purposes of lubricants are to:

  1. Reduce friction
  2. To prevent wear and tear
  3. Make sure the equipment is protected from corrosion
  4. Control the temperature (dissipate heat)
  5. The control of contamination (carries contaminants to a sump or filter)
  6. Transfer power (hydraulics)
  7. Provide a fluid seal
