chain is subjected to tensile force as well as impact forces. Due to tensile forces there is increase in

length of chain which makes the chain ineffectual. Present study deals with static structural analysis

of the roller chain for particular application, selection of the suitable material to enhance corrosion

resistance, weight optimization by changing certain dimensions and experimental validation of the

FEA results obtained.

I. INTRODUCTION

As far as the Indian scenario is considered economic growth is dependent on

industrialization. Current picture states that 63% of development of industry is dependent on efficient

use of machinery. In case of industry there is continuous requirement of transportation of material

and this requirement is fulfilled by Conveyor system, Jib crane, Pallet jack, Automatic Guided

Vehicles etc. Taking example of sugar mills there is requirement of transportation of materials like

coal, bagasse, sugar etc. These materials are in granular form and it is necessary to develop a proper

transport system which is long lasting, having less maintenance, which can sustain heavy loading and

shocks in rusty and dusty environment. Chain conveyor has the advantage of high transmission

efficiency for short distance transportation of materials over belt conveyors. Adding to it chain

conveyor has disadvantage of deformation of chain link due to tension force and jerk. Frequent

maintenance and timely lubrication is required to avoid corrosion of roller chain. Basically Solid

Bearing Roller Chain is used in sugar industry for transportation of coal. Vital components of roller

chain are outer and inner link which is also called as strip. The other important components are

roller, pin and bushing. Constructional features of roller chain shows that inner and outer links are

connected to each other by using pin which is press fitted between holes located on link plates. Press

fit constrains a rotary motion of pin. Further pin and bush are assembled together with slip fit

between them. Bushing is basically applied with bending, shock as well as shearing loads which is

transmitted by inner and outer links to it. Bushing and roller are assembled using slip fit. Roller is

subjected to impact loading when tooth of sprocket comes in contact with roller

Simple roller chain drive consisting of two sprockets connected by tight chain spans is

investigated. A kinematic model of a two-sprocket roller chain drive with straight spans was

presented, along with a procedure for calculating the total chain wrapping length.

Analytical predictions were compared to multi body simulation results and demonstrated that

the total wrapping length of the chain generally varies periodically with the tooth frequency.

Static and dynamic simulations of a continuously variable transmission (CVT) chain and

pulley system are developed in the MATLAB environment to determine the effect of a power

transmissions chain with involute inter-element contact surfaces on polygonal action in CVT

systems.

The static models developed here have been used as a tool for design of the inter-element

contact surfaces. Results from the static models show that, with proper design, CVT chains with

involute inter-element contact surfaces display less static mid-span displacement, smaller angle of

incidence at impact

The problem of determining the intensity of the pulsative loads, or technically, the impulsive

forces, has been studied in this paper. Also it has been deduced that when a chain engages a sprocket,

the links of the chain form the sides of a polygon. This polygonal structure is identified to be the

cause of the impulsive loads on the chain drive which contribute to excessive noise, excessive

vibration, and premature chain fatigue failure.

Weight of transported material (P1):

= 591.11 kg

= 5798.789N

Selection of suitable chain

From design of chain it is clear that weight of transported material will be resisted by selected chain

so we have to multiply by FOS to weight of transported material. Here for general applications FOS

is taken as 8.

Hence, Breaking Load (FB)

FB= P1. k = 5798.789 x 8 = 46390.40 N

From Designer guide for chain, according to DIN 8167 (ISO 19877), MRC 80X 125 is selected.

Now as breaking load = 46390.40 N

Operating load = 2/3 (Breaking Load)….. [9]

=2/3 (46390.40)

= 31525.33 N……………………….. (ii)

As the numbers of sprockets are 13 out of them minimum 6 numbers of sprockets will be engaged

during motion of chain.

Hence, Load on each roller =

VII. 3D MODELLING OF ROLLER CHAIN

VIII. STATIC ANALYSIS OF EXISTING CHAIN LINK

By static analysis we can compute stresses, displacement, in a component in steady loading

condition. As previously said tension force is basically applied on roller when the conveyor starts

and sudden jerk is experienced by chain link. So it is necessary to analyze stresses generated in the

chain link. For existing chain the material is ASTM-A53M low carbon steel. For analysis of roller

chain link first static structural module is selected in ANSYS 16.0. Then 3D model of roller chain

link created in CATIA V5 is imported in ANSYS 16.0. In next step meshing is done to model by

using tetrahedral and hexahedral elements. In the next step boundary condition is applied to roller

chain link by fixing one end and force of 5254.2 N is applied on roller at other end. Chain link is

then analyzed for deformation and stresses generated in it. Following are the results obtained in

analysis of roller chain link.

Current FOS = Allowable stress/ Generated stress

= 209/32.358

= 6.4589………………………… (v)

As factor of safety is beyond 6 it is clear that existing roller chain link is beyond safe limit and there

is scope for material removal for weight reduction, change of material and dimensional changes.

IX. ANALYSIS OF ROLLER CHAIN FOR VARIOUS MATERIALS

It is clear that we need to replace the material of the chain to overcome the problem of

corrosion and to give the chain higher strength. Chemical analysis by optical emission spectrometry

showed that existing material for roller chain is having lesser percentage of elements like NI, Cr, Mo

than required as per ASTM standards[10]. This basically results into reduced hardness of component.

For this purpose we have selected following materials for roller chain for analysis.

1. 8620-I (chrome-nickel-moly) Alloy Steel

From above table it is clear that compared to A-53M (Low carbon steel) SS 60 (Low carbon)

Hot Dipped Galvanized Steel is having 15.50% less weight. Along with this galvanized steel has the

advantage of higher resistance to corrosion which is basic requirement for working of chain in rusty

and dusty environment. Galvanized steel has advantage of reliability, automatic protection to

damaged area by sacrificial protection, lowest long term cost. Here we can see rise in deformation,

von misses stress and frictional stress. But this rise in stress is under tolerable limit so we have

selected SS 60 (Mild steel) for roller chain for particular application.

X. OPTIMIZATION ON BASIS OF CHANGE IN THICKNESS OF OUTER STRIP

Since the current design of roller chain link is beyond safe limit there is scope for weight

reduction by changing dimensions of link. Up till now weight reduction by reducing diameter of

outer link, centrally located holes, and circumference of the link plate edge is tried. But results can be

better by reducing the thickness of the inner and outer link of the roller chain. Thickness of the link is

5mm. We will reduce thickness in step by step manner with decrement of 0.25mm and will carry out

FEA on the model.

6 4 0.014594 46.188 127.13 0.7966

From above table it is clear that there is reduction in weight of the link with reduction in

thickness. Though there is significant rise in deflection, von misses stress and frictional stress these

values are under tolerable limit. So we modified the design of roller chain by changing thickness of

inner and outer link from 5mm to 4mm with weight reduction by 9.15%.

XI. OPTIMIZATION ON BASIS OF CHANGE IN DIAMETER OF ROLLER CHAIN LINK

As we studies in previous section further weight reduction is possible in roller chain. Now the

parameter selected for further weight reduction is outer diameter of the roller of the roller chain. As

there is slip fit between roller and pin inner diameter of the roller is fixed. But outer diameter of the

roller can be reduced for weight reduction. Current outer diameter of roller is 30 mm. We are going

to reduce the diameter in step by step manner by decrement of 2.50mm up till 20mm.

5 20 0.033678 115.92 161.87 0.55

From above table it is clear that as outer diameter of roller of chain link is decreasing weight

is also decreasing. If we consider the initial condition for existing material and link plate thickness

5.00mm, weight was 0.87688 Kg and now for 4mm link thickness and 20mm outer diameter weight

is 0.55004Kg. So percentage reduction in weight is 37.27%. Though there is considerable rise in

deformation, stress and frictional stress but these values are below allowable limit.

Also for SS 60 Yield strength is 470Mpa. And for safe design FOS should be at least 2 [9].

Hence,

Allowable stress for SS 60 (Hot dipped galvanized) =

Yield Strength / Allowable FOS

= 470/2

= 235Mpa

Now Current FOS = Allowable stress / Current Stress

= 235/ 115.92 ……… (Table 12. 2)

= 2.027

As the current FOS is 2.027 > 2. Our design of roller chain is safe.

XII. EXPERIMENTAL TESTING

For validating the results obtained by finite element analysis we have used universal testing

machine (UTM). UTM can be used for tension as well as compression test. As in present case

tension force is acting on the link of roller chain we are going to use UTM for testing the specimen

by tension test.

Specification of the UTM used for experimentation is as follows.

XIII. CONCLUSIONS

From the FEA and Experimental analysis results we can conclude that optimal value of

thickness of outer link in 4mm and that of outer radius of roller is 20mm respectively. Though

weight reduction we obtained for a single link seems tiny but with collective effect for such number

of links is significant. Following specific conclusion can be drawn from results obtained.

1. Experimental testing is done on SS 60 Mild Steel (Newly designed) model of roller chain and

results were found close to FEA results.

2. Weight in the newly designed roller chain link is reduced by 37.27%.

3. Newly selected chain is having von-misses stresses 29.94 %, Frictional Stresses 29.78 % and

deflection 29.95 % greater but is within allowable range.

4. Finally selected model for roller chain is having 4.0 mm thick outer link plate with roller

diameter as 20 mm with SS 60 Mild steel material.
