CS square worm screw lift form, size specifications, said the body is divided into: CS2.5 ~ CS500 total of 9, followed by the lifting force 2.5KN ~ 500KN. Transmission ratio N-type - General ratio; L-type - Slow ratio. Screw lift lubrication problems following analysis of the relationship between temperature and kinematic viscosity of the lubricant of the gear used, the N320 extreme pressure gear oil viscosity-temperature characteristics. Calculate the kinematic viscosity at 65 degrees, according to the empirical formula of the lubricant and temperature. By the formula t = 50 (50 / t) n was 65 = 50 (50/65) 3.1 = 180mm2 / S = 79.8mm2 / S = 80mm2 / S where the temperature t t kinematic viscosity of oil 50 degrees temperature of 50 degrees When the kinematic viscosity of oil to take the N320 in n 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 N320 extreme pressure Gear oil viscosity-temperature diagram, by opposing the use of shaft hoisting gear N320 intermediate pressure gear oil viscosity with temperature calculation and viscosity-temperature diagram, apparent, swl10 screw lift, when the temperature rises from 40 degrees to 65 degrees When, jwm005 screw lift, oil viscosity from 320mm2 / S down to 140mm2 / S, the viscosity decreases by 3180mm2 / S. This shows that as the temperature increases, the lubricating oil heat, Nantong screw lift, worm reducer its molecular heat motion increases, cohesion is reduced, so that a significant decrease in the viscosity of the lubricating oil, so that the lubricating properties of the lubricating oil is significantly reduced.
