Bevel Gear
Worm Gear
Bevel Gear having rolling friction.
Worm Gears having Sliding friction.
The efficiency of bevel gear is high.
The efficiency of worm gears is low.
Efficiency of bevel gears are constant irrespective of ratio and input speed.
Efficiency of worm depends on ratio and input speed
There is no self-locking in bevel.
Worm becomes self-lock when efficiency reduces below 50%.
It’s easy to rotate input shaft in bevel gear with rotating output shaft.
It’s not easy to rotate input shaft in worm gears with rotating output shaft because depend on ratio.
In bevel gear Input and output shafts are perpendicular and interesting.
In worm gears Input and output shafts are perpendicular and non-intersecting.
Bevel gear ratio not depended on a terminology of number of starts in bevel shafts.
Worm gears ratio depended on a terminology of number of starts in worm shafts.
Bevel can also be used for other than 90 degree transmission.
Worms is only for 90 degree transmission.
Bevel Gear are use for moderate speed reduction.
Worm Gears are use for high speed reduction.

Centrifugal Pump

Image
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
