DESIGN AND DEVELOPMENT OF MGIRI MODIFIED NMC CHARKHA

Abstract

—Charkha is a small spinning device produces yarns from fibers, which can be used to make clothes. The demand for cotton fabrics in the modern world has increased the production of cotton fabrics, making them more readily available. To increase production, charkhas are operated on electricity or on a battery-operated system. There is no reliable electricity available in most of India's rural areas. Due to low population density, there is much expense associated with installing and maintaining transmission lines. As a result, some areas will lack access to reliable electricity. For the elimination of manual labour operation of charkha by using electricity is the simplest option. However, there are some issues, like the yarn produced by using electrically operated charkha does not meet the definition of khadi that is the reason the option of using electrically operated charkha is not taken significantly. A detailed study was carried out on the design and analysis of the MGIRI modified NMC charkha. The basic necessity of this study is to enhance income and reduce drudgery. Efforts have been made to modify the existing design in order to increase productivity and ease of use. In the design, the mode and means of motion transmission have been redesigned. Reduction in rotating elements (gears and pulleys), the addition of bearings, and reduction in the weight of the machine have been undertaken.
