Differential Gear In Mechanical Auromobiles

Working of Differential Gear:

The differential has three jobs:  


•To aim the engine power at the wheels


•To act as the final gear reduction in the vehicle, slowing the rotational speed of the transmission one final time before it hits the wheels


•To transmit the power to the wheels while allowing them to rotate at different speeds.

Drilling Introduction

Drilling is easily the most common machining process. One estimate is that 75% of all metal-cutting material removed comes from drilling operations.

Drilling involves the creation of holes that are right circular cylinders. This is accomplished most typically by using a twist drill, something most readers will have seen before. The figure below illustrates a cross section of a hole being cut by a common twist drill:





The chips must exit through the flutes to the outside of the tool. As can be seen in the figure, the cutting front is embedded within the workpiece, making cooling difficult. The cutting area can be flooded, coolant spray mist can be applied, or coolant can be delivered through the drill bit shaft. For an overview of the chip-formation process, see the Chip Formation Section.



The characteristics of drilling that set it apart from other powered metal cutting operations are:

    * The chips must exit out of the hole created by the cutting.
    * Chip exit can cause problems when chips are large and/or continuous.
    * The drill can wander upon entrance and for deep holes.
    * For deep holes in large workpieces, coolant may need to be delivered through the drill shaft to the cutting front.
    * Of the powered metal cutting processes, drilling on a drill press is the most likely to be performed by someone who is not a machinist.



A view of the metal-cutting area of a drill press is shown below. The workpiece is held in place by a C-clamp since cutting forces can be quite large. It is dangerous to hold a workpiece by hand during drilling since cutting forces can unpredictably get quite large and wrench the part away. Wood is often used underneath the part so that the drill bit can overshoot without damaging the table. The table also has holes for drill overshoot as well as weight reduction. A three-jaw chuck is used since three points determine a circle in two dimensions. Four-jaw chucks are rarely seen since offset of the bit is not necessary. The next section contains illustrations of drill bit chucks. To get an idea of the differing configurations of three and four-jaw chucks, please see the equivalent lathe chucks.

Mechanical engineering is the best engineering and it is also very interesting. Man plays with machines in this engineering

Mechanical Engineering is the Best Engineering
Mechanical engineering is an engineering discipline that applies the principles of physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems. It is the branch of engineering that involves the production and usage of heat and mechanical power for the design, production, and operation of machines and tools. It is one of the oldest and broadest engineering discipline.

The Field Requires A Solid Understanding Of Core Concepts Including Mechanics, Kinematics, Thermodynamics, Materials Science, And Structural Analysis. Mechanical Engineers Use These Core Principles Along With Tools Like Computer-Aided Engineering And Product Lifecycle Management To Design And Analyze Manufacturing Plants, Industrial Equipment And Machinery, Heating And Cooling Systems, Motor Vehicles, Aircraft, Watercraft, Robotics, Medical Devices And More.

Their are lots of institutes in the world for this engineering. Having 3years diploma of associate engineering and BSc mechanical engineering. You can specialize in any mechanical field after doing BSc mechanical engineering.

Wah Engineering College Projects Exhibition 2010

Introduction

At Wah Engineering College we believe in synergistic collaboration with the industry for achieving academic excellence. Our students develop a design & build project at the end of their studies in which they demonstrate their engineering skills to cater the industry needs. This year’s projects in discipline of Mechatronics, Mechanical and Electrical Engineering were displayed in an exhibition at WEC Hall on Thursday 26th August 2010.
This exhibition provided an excellent opportunity to industry managers for talent hunt as well as to look for new ideas for their products. So a job fair was also arranged at the venue of the exhibition.

HORIZONTAL STIRLING ENGINE IN MECHANICAL ENGINEERING


AIM:
The project i want to make in the final year of Mechanical Engineering....

NAME:
It is basically the horizontal stirling engine.
It is excellent engine.

WORKING:
It works on the compression and  expansion of the gas in the cylinder.

HOW WE WILL WORK:
First of all we will make a CAD program. And make sure that the size and location suits my mill and material.
Now we will make the different parts of he engine. And in the last we will assembled them.


THIS IS NOT SO SIMPLE AS I AM TALKING ABOUT IT!!!!!!


 


Two Stroke Diesel Engine

The Two-Stroke Cycle
Like the four-stroke engine, the two-stroke engine must go through the same four events: intake, compression, power, and exhaust. But a two-stroke engine requires only two strokes of the piston to complete one full cycle. Therefore, it requires only one rotation of the crankshaft to complete a cycle. This means several events must occur during each stroke for all four events to be completed in two strokes, as opposed to the four-stroke engine where each stroke basically contains one event.

In a two-stroke engine the camshaft is geared so that it rotates at the same speed as the crankshaft (1:1). The following section will describe a two-stroke, supercharged, diesel engine having intake ports and exhaust valves with a 3.5-inch bore and 4-inch stroke with a 16:1 compression ratio, as it passes through one complete cycle. We will start on the exhaust stroke. All the timing marks given are generic and will vary from engine to engine.
