Screw jack screw lubrication problems following analysis of the relationship between temperature and kinematic viscosity of the lubricant lift the gear used, the N320 extreme pressure gear oil viscosity-temperature characteristics. Kinematic viscosity is calculated based on the experience of 65 degrees with the temperature of the lubricating oil formula. By the formula t = 50 (50 / t) n have 65 = 50 (50/65) 3.1 = 180mm2 / S = 79.8mm2 / S = 80mm2 / S where t when the temperature t of the kinematic viscosity of the oil temperature of 50 degrees 50 n When the kinematic viscosity of oil to take the N320 in the index n = 3.1 to calculate the extreme pressure gear oils 40 = 320mm2 / S corresponding to 50 = 180mm2 / S40 = 140mm2 / S corresponding to 65 = 80mm2 / S according to the results shown in EP N320 gear oil viscosity-temperature diagram screw lift, shaft hoisting gear by opposing the use of N320 intermediate pressure gear oil viscosity changes with temperature and viscosity-temperature diagram calculation, apparent, when the temperature rises from 40 degrees to 65 degrees, oil viscosity from 320mm2 / S down to 140mm2 / S, the viscosity values ??lower 3180mm2 / S. This shows that as the temperature increases, heat lubricants, worm reducer increased thermal motion of the molecules, cohesion is reduced, making the viscosity of the lubricant decreased significantly swl35 screw lift, so that the lubricating properties of the lubricating oil is significantly reduced.
