Rolling Contact Bearing Vs Sliding Contact Bearing


Sliding Contact Bearing Vs Rolling Contact Bearing


Sliding Contact Bearing



1. High Starting friction due to metal to metal contact.
2. Difficult to achieve sub-micon positioning.
3. The life of sliding contact bearing is more.
4. Difficult to estimate rigidity.
5. Unsuitable for extremely low speed.
6. Good in taking shock load.
7. Required Continuous lubrication supply.
8. Suitable for high speed applications.
9. The relative motion between the contact surfaces is of sliding types.
10. Low running friction due to oil film separation the journal & bearing surfaces.
11. Suitable for high loads.
12. It take load only in one direction either radial or axial.
13. Sliding contact bearing have small radial dimension & large axial dimension for same load carrying capacity.
14. Sliding contact bearing required auxiliary equipments like pump, filter, sump, pipe lines etc. 
15. In sliding contact bearing as there is no metal to metal contact, the operation is almost noiseless.
16. High initial cost.
17. High maintenance cost.
18. Sliding contact bearing are not available in standard size hence replacement is also difficult.
19. The design & manufacturing of journal bearing & housing is critical.
20. Sliding contact bearing have poor positional accuracy.

Rolling Contact Bearing

Cylindrical Roller Bearing N216-E - Order here!, 74,45 €
1. Low starting friction.
2. Easy to achieve sub-micon positioning.
3. The life of Rolling contact bearing is less due to fluctuating load.
4. Easy to estimate rigidity.
5. Suitable for extremely low speed.
6. Poor in taking shock load due to poor damping & metal to metal contact. Its subjected to plastic deformation under shock load & fatigue load.
7. Not required Continuous lubrication supply.
8. Not suitable for high speed applications.
9. The relative motion between the contact surfaces is of rolling types.
10. High running friction due to metal to metal contact.
11. Suitable for small or medium loads.
12. It take Combined radial & axial loads.
13. Rolling contact bearing have large radial dimension & small axial dimension for same load carrying capacity.
14. Rolling contact bearing don't required auxiliary equipments like pump, filter, sump, pipe lines etc. 
15. In Rolling contact bearing as there is metal to metal contact, the operation is almost noisy.
16. Low initial cost.
17. Low maintenance cost.
18. Rolling contact bearing are available in standard size hence they selected from manufacturer's catalogue. The replacement of rolling contact bearing is easy.
19. The design & manufacturing of journal bearing & housing is not critical.
20. Rolling contact bearing have poor positional accuracy because inner race with respect to outer race is independent of operating parameters.

Centrifugal Pump

Centrifugal Pump "Centrifugal pump  is a hydraulic machine which converts mechanical energy into hydraulic energy (i.e. pressure energy) by the use of centrifugal force acting on the fluid. " A centrifugal pump is the simplest machine which is used in various industries as well as in many daily applications to transfer fluid from lower head to higher head.  Centrifugal pumps are mostly used in chemical industries for easily transfer viscous fluids.   Also, it is less expensive than other pumping devices. In short, it is an excellent machine with efficient working in variety of applications. History of Centrifugal Pump- 1475- Italian engineer Francesco di Giorgio Martini designated mud lifting machine as a centrifugal pump. 1687- Denis Papin developed the first true  centrifugal pump  which was one with straight vanes that was used for drainage.  1851- John Appold, who was a British inventor, developed the first curved vane  centrifugal pump

Vapour Compression Refrigeration System

Image
Vapour Compression Refrigeration System Vapour-compression refrigeration  or  vapor-compression refrigeration system  ( VCRS )  in which the  refrigerant  undergoes  phase changes , is one of the many  refrigeration cycles  and is the most widely used method for  air-conditioning  of buildings and automobiles. Vapor-compression uses a circulating liquid  refrigerant  as the medium which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere. History:- 1805- The American inventor  Oliver Evans  described a closed vapor-compression refrigeration cycle for the production of ice by ether under vacuum. 1834-   American Great Britain,  Jacob Perkins , built the first working vapor-compression refrigeration system in the world. 1842-  American physician,  John Gorrie  who built a working prototype, but it was a commercial failure. 1850- American engineer  Alexander Twining  took out a British patent for a vapor compress

TURBOFAN ENGINE

TURBOFAN ENGINE The turbofan engine is a combination of the turbo prop and the turbojet engines combining the advantages of both. The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the turbo portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the fan, a ducted fan that uses the mechanical energy from the gas turbine to accelerate air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components.  In the 1950s, Rolls-Royce introduced the first turbofan in the world, namely, RB.80 Conway. Classification 1. According to Fan Location (a) Forward Fan Turbofan Engine (b) AFT Fan Turbofan Engine 2. According to Spools (a) Single Spool Turbofan Engine (b) Double Spool Turbofan Engine (c) Triple Spool Turb
