Gear drives - The heart ๐Ÿ’– of  mechanical engineering 

Without me machines getting die ⚙
Yeah ✌ it's TRUE!!

Gear drives is very important thing for power transmission. Without Gear power transmission is compare less..

The history of gear is from the woods ๐Ÿ‘‡


There are many different types of gear are used in various engineering application some of them most commonly used are as shown below :

1) - Spur Gear
2) - Helical Gear
3) - Herringbone Gear
4) - Bevel Gear
5) - Worm & Worm Gear
6) - Rack & Pinion Gear
7) - Spiral Gear

Spur gear :-
Teeth of this gear is parallel to the shaft or axis of gear usually gear ratio is 1:1 to 6:1.
Every gear ratio is. . . . . .
 
     Number of teeth on driven gear               
    ........................................................
     Number of teeth on driver gear


It's simple in construction, easy to manufacture, low cost & excellent precision rating

But but but center distance is limited, noise at high speed & large amount of stress..

Application of spur is in the clock, automobile industry, house hold application like washing machine etc..
_____________________________________________

Helical & herringbone gear :-
It's very powerful in gear industry it's use for carrying heavy load in heavy machinery it's gear ratio is same as spur

Much more Inclined teeth indicates  Helical Gear.




Double helical gear is nothing but example of  herringbone gear it's useful for heavy machinery


This both is very smoother & quiter,less were & tere , continually output
But but but
It is very costly,  during work heat generation is more,  it's required thrust bearing
Application of these gear is for printing, food processing machinery, fertilizer Industry,  plastic industry etc...
_____________________________________________

Rack & pinion gear :-
                                        whenever someone says convert rotary motion to liner motion which device can be use!  It's rack and pinion gear
In this image long bar indicates rack and the other one is spur gear or pinion.

It's use in lathe,driling & planning machines it's also use for automobile industry..

Bevel & spiral gear :-
                                        A gear working another  at angle to it by means of bevel gear and some difference of teeth  Is spiral gear.

Bevel gear and spiral gear  Is nearly equal to same. Only difference between them is teeth. Bevel gear has teeth  Is straight  And spiral gear has teeth is inclines.
Teeth of bevel gear can be classified as  straight inclined or hypoid.

This bevel gear is also called spiral bevel gear or spiral gear 
This  gear used for automobile, industries for marine applications, railway track inspection machine, steel plants and printing press is etc..
This bevel gear is also called straight bevel gear

Worm & worm gear :-
                   Worm and worm gear is a quiet similar to rack and pinion gear.
Worm and worm gear contains two element which is worm screw and worm wheel worm wheel.
Which is a helical gear.
which rotating capacity is up to 360 degree.

The application of these gear is electronic motors, rolling mills, automobile industries, mining machines, elevator, etc...

This is realistic & Accurate Example of GEAR


Analyze this picture gear to gear it's very helpful to understand G-E-A-R
