Popis: | Much research has been conducted in the past to reduce the weight of the vehicle to increase the fuel economy. The main aim of this research work is to reduce the weight of the automotive transmission gear box by removing the material in the gears without causing failure to the gear box. A transmission gear box helps in transmitting the torque or power from the engine to the drive axle at different velocity ratios based on the gears engaged and number of teeth in the gears. This project deals with the reduction of weight of the transmission gear box by saving the material and also increasing the transmission efficiency through weight reduction. This is achieved by stress analyzing and fabricating the gear box by drilling holes on the gears in red hot condition. Different types of holes with varying size and shape is made in the gears and analysis is done both in the software and in the prototype. Results prove that circular holes with 2.25 mm diameter in a gears increases 7% power and torque transmission and substantial increase in material savings and fuel economy. |
