![]() ![]() ![]() The pinion driving gear’s material and profile had been determined by designing due to the generated torque from the operator applied force. And the dimensions of the main parts like rack gear and spur gear and also the spring is determined by analyzing it to maximum bending, deflection and shear stress and loads produced on each of them. The dimensions of and materials of the vertical and horizontal frames or bars were determining by assumption of an operator medium height. These components are faced to different type of loads and forces like shear force, compressive and tensile loads. The machine has a number of different components such as vertical stand frame (bars), horizontal bars, and gear driving pinion gear inside the gear box that is used to drive the whole system to operate, attached to pulleys, shafts, drum and spring. Abstract Thresher machine is one of the agricultural machines that are used to separate the harvested grain from its stalk by hitting the stalk with rotary drum that have blade on it. ![]()
