Design analysis of jar coupler of mixer grinder and producing its prototype using additive manufacturing

Abstract

Jar Coupler are power transmission components used to transfer power from one shaft to other. Polymer gears finds its applications in all the segments of mechanical power transmission system because of its high strength to weigh ratio. They are manufactured using injection molding process which are costly due to mold cost and are more time consuming process. Additive manufacturing technique can be implemented because of its compatibility to produce complex designs and for customized requirements. The literature review shows that 3D printing technology is useful for Product development for fast product delivery. Jar Coupler used in Bajaj Mixer Grinding machine is considered in this project work and additive manufacturing method is used to produce the product other than conventional method. This Jar Coupler is made of Polyethylene polymer material. 3D modelling is done using Solidworks 2015 software. Finite Element analysis software SOLIDWORKS Simulation is used to study the Strength. Jar Coupler is Manufactured by 3D printing FDM technique with PLA and Nylon filament. This method of manufacturing the Jar Coupler will results into product development in short time and at low cost. These types of Jar Coupler can be used in any power transmission system and can be manufactured with required load carrying capacity and complex designs. Jar Coupler manufactured using additive manufacturing methods will reduce the manufacturing time, easy to make customized parts instantly, low rate of wear and increase in life of Jar Coupler.
