    Dynamic Performance Analysis of Non-metallic Spur Gear subjected to Variable Loads and Speeds

    By Dibakar Bandopadhya, Jagannath Sardar

    Abstract: The thrust for design and development of nonmetallic gear results in fabrication of inexpensive cement reinforced polypropylene based composite material spur gear. In this work, several experiments are conducted under variable loads and speeds and subsequently the resulting effect of heat emission on the performance of the gear is analyzed. A laboratory made gear test-rig is modified and suitably retrofitted; while pure polypropylene and 10 wt% cement reinforced spur gears …

    Investigation and Evaluation of Wear Characteristics of A Nonmetallic Spur Gear

    By Dibakar Bandopadhya, Jagannath Sardar

    Abstract: A thermoplastic composite material designed and developed for fabrication of nonmetallic composite spur gear. The composite is fabricated using Portland Pozzolanic Cement (PPC) as filler material into the polypropylene matrix followed by injection molding technique. However, geometrical structure of the developed product depends on the parameter like loading-unloading condition and temperature fluctuation that severely influence the material performance and shorten the product life. In the present work, the composite spur …

    A Stress Distribution Model along the Tooth Mating Surface of a Non-Metallic Spur Gear using the Hertz's

    By Jagannath Sardar, Dibakar Bandopadhya

    Abstract: A low cost cement reinforced polymeric composite material is designed and developed for fabrication of non-metallic automotive components such as gear. 10 wt% cement fillers are mixed up with pure polypropylene and injection-molding process is followed to fabricate the composite gear. Several experiments have been conducted to study the composite gear failure mechanism and resulting stress distribution along the tooth contact surface. For this, experimental data are used and Hertzian …
