Problems solved by technology

[0003] The power transmission of existing lathes is inseparable from the gears. Therefore, the life of the gears has a great impact on the normal operation of the lathe, and when the lathe is working, it will have a large impact on the surface of the gear due to wear and corrosion. Therefore, how to improve the wear resistance and corrosion resistance of gears is a technical problem that needs to be solved

Embodiment 1

[0021] A gear for a corrosion-resistant lathe, comprising the following steps:

[0022] (1) Preprocessing:

[0023] Soak the gear in the pretreatment solution for 40 minutes, then take it out, put the gear in isopropanol for 30 minutes, take it out, wash it with deionized water, and dry it to a constant weight, that is, Can;

[0024] (2) Modification treatment:

[0025] Put the above-mentioned treated gear into the ion nitriding furnace, and vacuum the air pressure in the ion nitriding furnace to 15Pa, pass argon gas into the ion nitriding furnace for ion bombardment, and wait until the temperature in the ion nitriding furnace When it reaches 370°C, stop the introduction of argon, keep it warm for 1.5 hours, and then inject nitrogen and hydrogen for low-pressure ion nitriding. Adjust the pressure of nitrogen and hydrogen to make the pressure in the ion nitriding furnace 210Pa. Process for 3 hours, then cool naturally to room temperature, then take it out;

Description

technical field [0001] The invention belongs to the technical field of lathe accessories, and in particular relates to a gear for a corrosion-resistant lathe. Background technique [0002] A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. Drills, reamers, reamers, taps, dies and knurling tools can also be used for corresponding processing on the lathe. [0003] The power transmission of the existing lathe is inseparable from the gears. Therefore, the life of the gears has a great impact on the normal operation of the lathe. When the lathe is working, it will cause a large damage to the surface of the gear due to wear and corrosion. Therefore, how to improve the wear resistance and corrosion resistance of gears is a technical problem that needs to be solved. Contents of the invention [0004] The object of the present invention is to provide a corrosion-resistant gear for lathes in view of the existing problems. [0005] The present ...
