Types:-
There are two types of air bearing systems:-
Aerostatic.
Aerodynamic.
Mechanism AEROSTATIC :-
Externally pressurised: A separate external supply of air is fed
under pressure between the
two surfaces being kept apart....
Mechanism AERODYNAMIC:-
• Self generating: The supporting film is generated by the
relative motion of the two surfaces bei...
Benefits/Advantages:-
1. Greater Precision.
2. High Speed.
3. Increased Tool Life.
4. Improved Surface Finish.
5. Long Bea...
Disadvantages:-
• High geometric accuracy during
manufacturing.
• Clean and dry supply of pressured air.
• High prizing.
Applications:-
• Hover Craft-Transport.
Application:-
• Uplifting heavy weights-
We can lift up to 5 tons without efforts using
this technology.
Application & Scope:-
• Upcoming vehicles will use this technology.
Termination:-
• There will be no issue of lifting up much more
heavy loads in future if we use this
technology. Transporta...

Air Bearing

  1. 1. Welcome Presentation On Air Bearing By- Ketan Shete
  2. 2. Intent:- • Intro. • Types of bearings. • Mechanism. • Benefits/Advantages. • Disadvantages. • Applications & Scope. • Termination.
  3. 3. So What is Bearing…..? A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts.
  4. 4. Another Definition:- An air bearing is a non-contacting system where a gas film (typically air) acts as the lubricant that separates the two surfaces in relative motion.
  5. 5. Types:- There are two types of air bearing systems:- Aerostatic. Aerodynamic.
  6. 6. Mechanism AEROSTATIC :-
  7. 7. Externally pressurised: A separate external supply of air is fed under pressure between the two surfaces being kept apart. It is a continuous flow system where pressurised gas from the source flows through restrictors into the clearance between the bearing surfaces escaping to the atmosphere at the outside edges of the bearing.
  8. 8. Mechanism AERODYNAMIC:- • Self generating: The supporting film is generated by the relative motion of the two surfaces being kept apart. • An aerodynamic bearing can be of several types. The design characteristics differ greatly between journal and axial bearings and they can suffer problems of instability.
  9. 9. Benefits/Advantages:- 1. Greater Precision. 2. High Speed. 3. Increased Tool Life. 4. Improved Surface Finish. 5. Long Bearing Life. 6. Lack of Maintenance. 7. Low Thermal Growth. 8. Large Load Capacity. 9. Reduced Vibration
  10. 10. Disadvantages:- • High geometric accuracy during manufacturing. • Clean and dry supply of pressured air. • High prizing.
  11. 11. Applications:- • Hover Craft-Transport.
  12. 12. Application:- • Uplifting heavy weights- We can lift up to 5 tons without efforts using this technology.
  13. 13. Application & Scope:- • Upcoming vehicles will use this technology.
  14. 14. Termination:- • There will be no issue of lifting up much more heavy loads in future if we use this technology. Transportation will affect much more with this technology. Speed will speed & efficiency up at much extent of transport .
