Embodiment 1～6

[0031] According to the parts by weight in Table 1, take the required amount of pour point depressant, antirust agent, antioxidant, demulsifier, antifoaming agent and add them to the base oil (viscosity grade is 32, 46, 68) respectively, Heat and stir at 70°C until completely uniform, then lower the temperature to 60°C, add extreme pressure antiwear agent, stir until completely uniform to obtain the special oil composition for gear hobbing machines. The type and amount of each component in the composition are specifically shown in Table 1.

[0032] Among them, T321 is a sulfurized olefin; T307 is a phosphorothioate double ester amine salt; Irgalube 353 is a phosphorothioate; T205 is a zinc dialkyl dithiophosphate derivative; T501 is 2,6-di-tert-butyl p-methyl T534 is alkylated diphenylamine; T746 is alkenyl succinate; T747A is alkenyl succinate half ester; Vx-1-248 is polymethacrylate; T803B is polyalphaolefin; T921 is acrylic acid Ester and ether copolymer.

Embodiment 7

[0034] For the extreme pressure and wear resistance (maximum non-seizing load PB) of the compositions in [Examples 1 to 6], compatibility with hydraulic systems of gear processing machine tools such as gear hobbing machines (viscosity index, pour point, copper sheet corrosion, Liquid phase corrosion, air release value, foam characteristics, anti-emulsification performance) were tested, and the test results are shown in Table 2.

Embodiment 5

[0035] Extreme pressure and anti-wear properties are one of the most important properties of special oils for gear hobbing machines. For each composition in [Examples 1-6], the maximum non-seize load PB index was tested. The larger the maximum non-jamming load PB value, the better the extreme pressure and anti-wear performance of the special oil for gear hobbing machines. [Examples 1-6] Among the extreme pressure and anti-wear properties of each composition, the maximum non-seizing load P B The values ​​are all greater than 588N, indicating that each composition can meet the special requirements of gear hobbing and other processing techniques. In comparison, the maximum non-jamming load PB value of each combination is as follows: [Example 5] > [Example 3] > [Example 2] = [Example 4] = [Example 6] > [Example 1】. Therefore, based on the above evaluation of the extreme pressure and anti-wear performance of special oil for gear hobbing machine, the maximum non-jamming load P B...

Abstract

The invention relates to special oil composition for a gear hobbing machine and an application of the special oil composition, and mainly solves the problems that hydraulic oil is polluted after leakoil enters a hydraulic system due to poor compatibility between oil for the gear hobbing machine and the hydraulic system of equipment and a tool is not protected ideally as a result of insufficient lubrication property of oil products in the prior art. The oil composition is prepared from the following components in parts by weight: a) 100 parts of mineral base oil, b) 0.1-10 parts of extreme-pressure anti-wear agent, c) 0.1-1.0 part of a pour point depressant, d) 0.01 to 0.5 parts of a rust inhibitor and e) 0.01 to 2.0 parts of an antioxidant; the extreme-pressure anti-wear agent is a mixture of at least one of sulfurized olefin, phenyl sulfide, sulfurized aliphatic acid ester or chlorinated paraffin and at least one of thiophosphoric acid diester amine salt, phosphate amine salt, phosphorothioate, zinc dialkyldithiophosphate salt or a derivative of the zinc dialkyldithiophosphate salt. With adoption of the technical scheme, the problems are better solved, and the extreme pressure anti-wear agent can be used in industrial production of the special oil composition for the gear hobbing machine.

Description

technical field [0001] The invention relates to a special oil composition for gear hobbing machines and its application. Background technique [0002] Gear hobbing machine is the most widely used machine tool in gear processing machine tools. On gear hobbing machine tools, hobs generally process spur gears, helical gears and herringbone cylindrical gears and worm gears according to the generation method. When this kind of machine tool uses a special hob, it can also process various special tooth-shaped workpieces such as splines and sprockets. [0003] During the working process, the hob directly contacts the metal workpiece with high load, and it runs overloaded for a long time, and the tool will be continuously worn and generate a lot of heat. In order to reduce tool wear, prolong tool life, and improve workpiece finish and work efficiency, higher requirements are put forward for the oil used for gear hobbing machines, such as the extreme pressure and anti-wear performanc...
