Bevel gears are used to transmit motion between two intersecting shafts at any angle. The design procedure involves selecting materials, tooth profiles, and module based on requirements and strength calculations. Bevel gears are then designed with the proper diameters, cone distance, and face width. Design is checked for surface and bending stresses. Bevel gears are commonly used in differentials and hand drills to change the direction of rotation. They allow transmission of power between non-parallel shafts but require precise mounting and bearings.

A helical gear has teeth in form of helix around the gear. Two such gears may be used to connect two parallel shafts in place of spur gears. The helixes may be right handed on one gear and left handed on the other. The pitch surfaces are cylindrical as in spur gearing, but the teeth instead of being parallel to the axis, wind around the cylinders helically like screw threads.

The various forces acts on the reciprocating parts of an engine.
The resultant of all the forces acting on the body of the engine due to inertia forces only is known as unbalanced force or shaking force.
Bevel gears are used to transmit motion between two intersecting axes shafts. The pitch surface of a bevel gear is a frustum of a cone. The teeth of the bevel gears may be straight or spiral.
Although the bevel gears are usually made for a shaft angle of 90°, they can be produced for almost any shaft angle.

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.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

2. Bevel Gears
• Bevel gears are used to transmit motion between two
intersecting axes shafts.
• The teeth of the bevel gears may be straight or spiral.
• Although the bevel gears are usually made for a shaft angle of
90 degree, they can be produced for almost any shaft angle.

8. APPLICATIONS OF BEVEL GEARS
• Bevel gears are used in differential drives, which can
transmit power to two axles spinning at different
speeds, such as those on a cornering automobile.
• Bevel gears are used as the main mechanism for a hand
drill. As the handle of the drill is turned in a vertical
direction, the bevel gears change the rotation of the
chuck to a horizontal rotation. The bevel gears in a
hand drill have the added advantage of increasing the
speed of rotation of the chuck and this makes it possible
to drill a range of materials.
9. Bevel Gears
Advantages
• This gear makes it possible
to change the operating
angle.
• Differing of the number of
teeth (effectively diameter)
on each wheel
allows mechanical
advantage to be changed.
Disadvantages
• One wheel of such gear is
designed to work with its
complementary wheel and
no other.
• Must be precisely mounted.
• The shafts bearings must be
capable of supporting
significant forces.
