Description

Technical Field

[0001] The utility model relates to the technical field of thrust washer processing, in particular to two-stage thrust washer gas soft nitriding equipment. Background Art

[0002] A two-stage thrust washer is a sealing element used in automotive engine components. It is usually composed of two gaskets of different hardness or thickness stacked together to withstand thrust and reduce vibration when the engine is running.

[0003] During production, two-stage thrust washers are treated with gas nitriding to improve their surface hardness, wear resistance and corrosion resistance. However, existing gas nitriding equipment has no driving structure and cannot drive the workpiece to rotate, so that the gas can contact the workpiece surface evenly and quickly. Therefore, we propose a two-stage thrust washer gas nitriding equipment. Utility Model Content
