Description
Summary:Polymer gears are replacing the metal gears in various applications due to some of their inherent properties. Polymer gears have lower inertia, less weight and operate much quieter in comparison to metal gears. In this work, glass fiber reinforced functionally graded material based High-Density Polyethylene (HDPE) gears is fabricated using injection molding machine for the investigation of transmission efficiency. Glass fiber filled HDPE materials in the punch are rotated at 1800 rpm for 2 min. for the gradation of the fibers. Homogeneous and neat HDPE gears are also fabricated for comparative study. Polymer gears are running at different speed (600, 800, 1000 and 1200 rpm) and torque (0.8, 1.2, 1.6 and 2 Nm) to investigate the transmission efficiency. Gears are operated for 1.2×105 cycles. The experiments are carried out using a power absorption type polymer gear test rig. It is concluded from this work that transmission efficiency of these polymer gears is significantly affected by torque. Speed has less significant effect on transmission efficiency of polymer gears.
