This document presents information on a bushed pin type flexible coupling. It begins with an overview of couplings and their purpose in connecting shafts to transfer motion. It then discusses different types of couplings, including rigid and flexible couplings. The main focus is on the design of a bushed pin type flange coupling, including the dimensions and considerations for designing the hub, key, flange, and bolts. Advantages of this type of coupling include being torsionally stiff with good vibration damping, while limitations include sensitivity to chemicals and difficulty in balancing. References used in the presentation are also listed.
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.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

4 Advantages & Limitation Of Flange Coupling
5 Application Of Flange Coupling
6 References
3. COUPLING
Couplings are mechanical elements that ‘couples’
two drive elements (shafts) which enables motion
to be transferred from one element to another.
4. Types of Shafts Couplings
1. Rigid coupling 2. Flexible
coupling
1. Rigid coupling : It is used to connect two
shafts which are perfectly aligned.
types of rigid coupling are
a)Sleeve or muff coupling.
b)Clamp or split-muff coupling
5. 2.Flexible coupling : It is used to connect
two shafts having both lateral and angular
misalignment.
Types of flexible coupling are
a)Bushed pin type coupling,
b)Universal coupling,
c)Oldham coupling
7. Design of Unprotected type Flange
Coupling
The usual proportions for an protected type cast iron
flange couplings
d = diameter of the shaft or inner diameter of the hub
D= Outside diameter of hub D=2d
Length of hub, L= 1.5d
Pitch circle diameter of bolts, D1=3d
Outside diameter of flange,
D2= D1+ ( D1– D) = 2 D1– D= 4d
Thickness of flange tf =0.5d
Number of bolts =3, ford upto 40 mm
=4, for d upto 100 mm
=6, for d upto 180 mm
8. d =Diameter of shaft or inner diameter of hub,
τs =Allowable shear stress for shaft,
D=Outer diameter of hub,
tf =Thickness of flange
τc=Allowable shear stress for the flange material
d 1=Nominal or outside diameter of bolt,
D1 =Diameter of bolt circle,
n=Number of bolts,
τb= Allowable shear stress for bolt
σ cb,, =Allowable crushing stress for bolt
τk= Allowable shear stress for key material
σ ck= key material
9. 1. Design for hub
The hub is designed by considering it as a
hollow shaft,
transmitting the same torque (T ) as that of a
solid shaft
T= T = (π/16)×τc×(D4-d4)/D
The outer diameter of hub is usually taken as
twice the diameter of shaft.
The length of hub ( L ) = 1.5d
10. 2. Design for key
The material of key is usually the same as that
of shaft. The length of key is taken equal to the
length of hub
l=L
T = l× w×τ ×(d /2)
(Considering shearing of the key)
T = l × t/2 × σC × (d /2)
(Considering crushing of the key
11. 3. Design for flange
The flange at the junction of the hub is under
shear while transmitting the torque.
T =Circumference of hub × Thickness of flange
× Shear stress of flange × Radius of hub
T= π D × tf × τc × D/2
T= π × tf × τc × D2/2
The thickness of flange is usually taken as half
the diameter of shaft
12. 4. Design for bolts
Load on each bolt (F)=
(π/4) (d 1
2 ) (τb)
Total load on all the bolts (F) =
(π/4) (d 1
2 ) (τb)(n)
The bolts are subjected to shear stress due to
the torque transmitted
(T)= (π/4) (d 1
2 ) (τb)(n) (D1/2)
From this equation, the diameter of bolt
(d 1) may be obtained.
13. We know that area resisting crushing of all the
bolts = n× d 1 × tf × tp
crushing strength of all the bolts
= n× d 1 × tf × tp × σCb
∴Torque = n× d 1 × tf × tp × σCb × (D1/2)
From this equation, the induced crushing stress
in the bolts may be checked
14. Advantages and Limitations
Advantages
1.Torsionally stiff
2.No lubrication or maintenance
3.Good vibration damping and shock absorbing
qualities
4.Less expensive than metallic couplings
5.More misalignment allowable than most metallic
couplings
Limitations
1.Sensitive to chemicals and high temperatures
2.Usually not torsionally stiff enough for positive
displacement
3.Larger in outside diameter than metallic coupling
4.Difficult to balance as an assembly
