Abstract:
This research focuses on the optimization of the performance parameters namely, surface temperature, wear rate, and
transmission efficiency of polymer gears. Three different polymers namely, acrylonitrile butadiene styrene, high-density
polyethylene, and polyoxymethylene are selected for manufacturing the gears. A total of 27 experiments are carried out
to test these gears at different torque and speed conditions. The torque values are taken as 0.8, 1.2, and 1.6 Nm,
whereas the speeds of 600, 900, and 1200 r/min are chosen for the study. The optimal setting of operating parameters
(gear material, speed, and torque) is obtained by using a hybrid multi-criteria decision-making approach that includes the
analytical hierarchy process and technique for order of preference by similarity to ideal solution. The optimal setting of
performance parameters is obtained with polyoxymethylene gear running at the torque and speed conditions of 0.8 Nm
and 900 r/min, respectively
