Abstract

Lubricating is one of the methods to prevent temperature rise and wear due to friction among gearbox components. The lubricant quality is an essential factor in ensuring lubricant functions optimally. Long-term use of the machine changes lubricant quality, which can be measured by viscosity parameters and Total Acid Number (TAN). This research aims to determine the effect of machine operating time on viscosity and TAN lubricant changes of milling machine gearbox heads (Headstock) used for educational purposes. The study used a quantitative research method in which data was collected using statistical data analysis tools and selecting a random sampling. Forty samples of Shell Tellus 46 lubricant were taken every 5 hours for 200 operation hours with an operating temperature of 27.5-44.4°C and 300 rpm speed. Viscosity testing uses Visgage and Fluidscan to check TAN. Data analysis using a simple linear regression analysis method with the statistical software Minitab 21.3. The results showed that operating time had a significant effect on: 1) a 95% change in viscosity value with 3.67 cSt (7.39%) decline or 0.018776 cSt per operation hour; 2) 99.34% change in TAN value with 0.27 mg KOH/g (16.56%) increase or 0.001297 mg KOH/g per operation hour.

Abstract

Lubricants are chemical substances that are generally in liquid form, which are used in frictional components. Its function is to reduce friction, reduce wear, reduce vibration, maintain the age of the tool or component and maintain temperature during operation. The purpose of this study was to determine the effect of a mixture of lubricants on TAN (Total Acid Number) and viscosity, and to determine the effect of time on TAN (Total Acid Number) and viscosity. It was carried out with 5 different concentrations of the mixture, namely 100:0, 80:20, 90:10, 95:5, 0:100 then the concentration of this mixture was tested on the headstock gearbox of a conventional lathe DoALL LT 13 for 21 hours at each concentration, then the test is carried out on the lubricant sample repeated 3 times every 1 hour. The viscosity test on lubricating oil samples was carried out at 40°C and the TAN (Total Acid Number) test was carried out at room temperature. This research was conducted using the ANOVA method and it was concluded that the analysis showed that mixing and time had a significant effect on TAN (Total Acid Number) and viscosity.
