Belts are loops of flexible material used to mechanically link rotating shafts and transmit power between them. They work by looping over pulleys on two shafts, and can drive the pulleys in the same or opposite directions. Belts are a simple, economical way to transmit power between shafts without requiring parallel alignment and provide protection against overloads and shocks.

Literature Review on Simulation and Analysis of Timing Chain of an Automotive...IJERA Editor
The current trend in automotive industry is to achieve compact, efficient, reliable systems. Engine timing drives
used in engines are one of the most critical systems. Timing belts are subjected to excessive elongation and
wear, while timing gears contribute excess mass and inertia in the system. Hence timing chains are preferred
widely, in various high performance engines. Chain drives are easy to assemble and adjust, highly efficient,
durable, reliable, compact and capable of attaining a wide range of power and speed capacities. In spite of these
advantages their complex dynamic behaviour is not well researched. With the improvement of the speed and
load of the automotive engine, and silent chain technology, as silent chain has a compact structure, high
transmitting efficiency, high reliability and high wear resistance, its vibration and noise is low, and the silent
chain have the advantage of life-long maintenance-free, it significant overcomes the gear drive and belt drive
performance, therefore, the silent chain is increasingly widely used in automotive engine timing system. In this
present review dynamic analysis as well as analysis of automotive engines timing silent chain system are
studied

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.

1. 1. A belt is a looped strip of flexible material,
used to mechanically link two or more
rotating shafts.
2. They may be used as a source of motion,
to efficiently transmit power, or to track
relative movement. Belts are looped over
pulleys.
3. In a two pulley system, the belt can either
drive the pulleys in the same direction, or
the belt may be crossed, so that the
direction of the shafts is opposite.
2.
3.
4.
5.
6.
7.
8.
9. They are simple. They are economical.
Parallel shafts are not required.
Overload and jam protection are provided.
Noise and vibration are damped out. Machinery life
is prolonged because load fluctuations are
cushioned (shock-absorbed).
They are lubrication-free. They require only low
maintenance.
They are highly efficient (90–98%, usually 95%).
Some misalignment is tolerable.
They are very economical when shafts are
separated by large distances.
10. The angular-velocity ratio is not necessarily
constant or equal to the ratio of pulley diameters,
because of belt slip and stretch.
Heat buildup occurs. Speed is limited to usually
7000 feet per minute (35 meters per second).
Power transmission is limited to 370 kilowatts (500
horsepower).
Operating temperatures are usually restricted to –
31 to 185°F (–35 to 85°C).
Some adjustment of center distance or use of an
idler pulley is necessary for wear and stretch
compensation.
A means of disassembly must be provided to install
endless belts.
11. Chain drive is a way of transmitting mechanical
power from one place to another.
It is often used to convey power to the wheels of a
vehicle, particularly bicycles and motorcycles.
It is also used in a wide variety of machines besides
vehicles.
Most often, the power is conveyed by a roller chain,
known as the drive chain, passing over a sprocket
gear, with the teeth of the gear meshing with the
holes in the links of the chain.
The gear is turned, and this pulls the chain putting
mechanical force into the system..
12.
13. Following are the details of a crossed belt drive. Calculate the
length
of the belt?
Diameter of the driver : 200 mm
Diameter of the follower : 400 mm
Center distance of the drive : 2m
Speed of the driver : 400 rpm
Angle of contact : 197.3
Determine the length of the belt.
Solution:
D1 = 200 mm
D2= 400 mm
C = 2m
N1 = 400 rpm
Length of the belt = L =2C+ П / 2 (D1+ D2) + (D1+ D2) / 4C
= (2x2) + П / 2 (0.2+ 0.4) + (0.2+ 0.4) / 4x2
= 4.99 m
