Use of Gear Advantage of Teeth on Gear
Use of Gears- ● To reverse the direction of rotation ● To increase or decrease the speed of rotation ● To move rotational motion to a different axis ● To keep the rotation of…
Terminology of Spur Gear
● Pitch surface: The surface of the imaginary rolling cylinder (cone, etc.) that the toothed gear may be considered to replace. ● Pitch circle: A right section of the pitch surface. ● Addendum circle: A circle…
Gear Introduction
A gear also known as "gear wheel" is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part in order to transmit torque. Two or…
Efficiency of the engine
The efficiency of the engine depends to a large extent upon the following criteria: · Compression · Combustion Process · Air/Fuel Mixture · Mechanical Design · Lubrication 1) Compression The higher…
How to Produce More Engine Power
Car manufacturers are constantly playing with all of the following variables to make an engine more powerful and/or more fuel efficient. 1. Increase displacement - More displacement means more power because…
Engine Problems
Three fundamental things can happen: a bad fuel mix, lack of compression or lack of spark. Beyond that, thousands of minor things can create problems, but these are the "big…
Components of Automobile Engine
1) Camshaft: Camshaft is a type of rotating device or apparatus used in piston engines for propelling or operating poppet valves. Camshaft comprises of series of cams that regulates the…
Construction and Working of Differential Assembly
Torque is supplied from the engine, via the transmission, to a drive shaft (British term: 'propeller shaft', commonly and informally abbreviated to 'prop-shaft'), which runs to thefinal drive unit that contains the differential. A spiral bevel pinion gear…
Need of a Differential
Car wheels spin at different speeds, especially when turning. Each wheel travels a different distance through the turn, and that the inside wheels travel a shorter distance than the outside…
