DESIGN AND ANALYSIS OF MODIFIED IDLER IN DRAG CHAIN CONVEYOR

The 20th century has been a period of rapid developments in manufacturing technology. Mass production has become the dominant manufacturing activity in the world. Mass production means single-product, large-lot-size production. The major problems in Mass production is a high quantity of products transfer from one place to another place Several effective methodologies have been developed for solving Mass production problems such as, conveyors, cranes, pumping System, trucks, and special purpose vehicles. The focus of this paper is redesigning the chain type conveyor and eliminates the errors. This paper work is mainly concentrated on modify the existing idler in the chain type conveyor and eliminate the failure of idlers due to various errors. Due to introducing anti frictional bearing by modified existing system of frictional type NiHard bearing bush, the following benefits are derived; increased life span of idler consequent to that then consumption of idlers will get reduced drastically. Breakdown of machining have been avoided due to failure of idlers. Maintenance is reduced, on account of consumption of idlers and its spares. Lesser power is needed due to reduced load to the conveyor drive motor because of introducing anti frictional bearing
