DESIGN AND ANALYSIS OF SHAFT STRENGTH IN OIL DRAINING MACHINE

The oil draining machine is designed to facilitate industries, particularly household food industries. This machine aims to optimize the process of removing excess oil from food after cooking, thereby providing time efficiency compared to the manual method of letting the oil drain passively. This study focuses on designing, developing, and analyzing the shaft of the oil draining machine, as well as conducting a torsional load test to determine the values of von Mises stress, displacement, and safety factor. The operating principle of the oil draining machine is powered by a 2 HP (1.5 kW) electric motor that generates 1400 RPM. This electric motor drives two pulleys, which in turn rotate the shaft. As the shaft rotates, it spins the filtering mechanism, causing the food inside to rotate and allowing the remaining oil to separate from the food. The shaft is made of solid steel with a diameter of ∅19 mm, using AISI 1045 cold-drawn steel as the material. From the testing and analysis conducted on the shaft, the results show a von Mises stress value of 216.1 MPa, a maximum displacement of 18.549 mm, and the smallest safety factor value of 2.5. The analysis and design were carried out using SolidWorks software.
