STUDY OF THE OPTIMUM DESIGN PARAMETERS OF CHAIN OF CHAIN CONVEYOR SYSTEM USING FEA

MECHANICAL ENGINEERING

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. Apart from that, other industries also use these chains frequently for process atomization. However, failure of this chain is challenging problem in these industries which causes huge losses to these industries and in turn economic growth of the state 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
