The rear axle final drive (1) transmits power at a 90 degree angle from the transmission and (2) reduces the engine speed to provide the transmission's top gear ratio. (3) Cars typically use a final drive ratio of around 4:1. Bevel, hypoid, and worm gears are commonly used in final drives to achieve the necessary functions.
Transmission System
The word ‘Transmission’ means the whole of the mechanism that transmits the power from the engine crankshaft to the rear wheels, providing the suitable variations of the engine torque at the road wheels, whenever required.

A clutch is a mechanism which enables the rotary motion of one shaft to be transmitted at will to the second shaft, whose axis is coincident with that of first. Clutch is located between the engine and gearbox. When the clutch is engaged, the power flows from the engine to the rear wheels through the transmission system and the vehicle moves when the clutch is disengaged, the power is not transmitted to the rear wheels and the vehicle stops, while the engine is still running.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.
2. Rear Axles Final-drive
The rear axles final drive
(i) Transmits the drive through a angle of 90degrees, and
(ii) Gears down the engine revolutions to provide a
‘direct top’ gearbox ratio.
(iii) In the case of cars a final drive ratio of approximately
4 : 1 is used.
(iv) Bevel or worn gears are employed to achieve the
various functions of the final drive.
3. TYPES OF FINAL DRIVES
1. Bevel Gears
– Straight Bevel.
– Spiral Bevel.
2. Hypoid Gear
3. Worm and Wheel Drive
4. Bevel Gears
• The geometry of a bevel gear
layout, which represents two
friction cones ‘A’ forming the
crown wheel and ‘B’ the pinion.
• For avoidance of slippage and
wear, the apex of the pinion must
coincide with the centre line of the
crown wheel.
• It is necessary to mount the gear in
the correct position so that angle
of the bevel is governed by the
gear ratio.
7. Backlash In Gears
• Backlash is most commonly created by cutting
the teeth deeper into the gears than the ideal
depth.
• Another way of introducing backlash is by
increasing the center distances between the
gears.
• Standard practice is to make allowance for half
the backlash in the tooth thickness of each gear.
8. Straight Bevel
• The tapered teeth, generated from the centre, are machined on the case-
hardened steel gears and then ground together to form a ‘mated pair’.
• The position of the crown wheel relative to the pinion determines the
direction of rotation of the axle shaft.
• For correct meshing and for setting the clearance between the teeth
(backlash), adjusters in the form of distance pieces, shims or screwed rings
are used.
• When backlash is too small, expansion results due to heat and wear is
caused by lack of lubrication.
• On the other hand excessive backlash produces slackness and noise.
• Each manufacturer recommends a suitable backlash, but it is generally in
the region of 0.15 mm for cars and 0.25 mm for heavy vehicles.
9.
10. Spiral Bevel
• Although the straight bevel is cheaper and
mechanically efficient, the meshing of the gears
causes an unwanted noise, which has been
reduced by introducing a helical form of tooth.
• Figure illustrates the construction of the gear, A
number of teeth are generated from the centre of
the crown wheel, and form a left-handed spiral in
the case of the pinion.
11.
12. Hypoid Gear
• This type of gear is the commonly used now a days.
• The pinion axis of this gear is offset to the centre line of the crown wheel.
• Although the gear can be placed above or below the centre, but in cars it is
always placed below to allow for a lower propeller shaft so that a reduction
in the tunnel height is possible.
• If the axis is lowered, the tooth pitch of the pinion increases, so that for a
given ratio, the pinion diameter can be larger (30 percent for normal offset).
• This enables the use of a stronger gear specifically on commercial vehicles.
13.
14. Worm and Wheel Drive
• Since this drive is expensive, it is rarely used nowadays as a
final drive on light vehicles, but is still used on heavy vehicles.
• However, this type of gear has a number of other applications
on motor vehicles.
• It can be employed to provide a very quiet and long-lasting
gear, but efficiency is less than the bevel (94 percent against 98
percent).
• This type of gear provides a large reduction in a small space.
