Introduction:

The high quality manufacturing of the drum gear coupling includes the strength of the parent in the coupling transmission part and the fatigue strength of the coupling transmission part or the strength and fatigue strength of the parts and elastic components connected to the coupling transmission part. However, the surface treatment of the coupling transmission is also a problem that cannot be ignored, which relates to the surface corrosion of the whole coupling and affects the normal use and service life of the gear coupling.

The advantages and treatment methods of surface material of drum gear coupling:

For the metal surface treatment of the drum gear coupling transmission parts, it is generally necessary to add a layer of material on the metal surface of the coupling transmission parts to avoid contact with the air, its main advantages are: prevent rust, corrosion, beautiful surface. Usually the surface treatment is mainly the role of _, and the drum gear coupling surface treatment also includes the surface hardness of the following will give you a few points about the coupling transmission parts of the surface treatment method:

(1) Surface spray painting: is a relatively simple and widely used surface treatment, its cost is low, but the surface and rust prevention performance is poor, generally used in large gear coupling.

(2) blackening treatment: blackening treatment is a kind of surface treatment widely used in tooth coupling, mainly divided into heating blackening and room temperature blackening, which heating blackening ink color is better than room temperature black ink, room temperature blackening cost is higher. Heating blackening is cheap but ineffective. Normal temperature blackening principle _ is to use liquid medicine to turn the surface of iron and steel pieces into black, prevent rust, corrosion. Materials should be rigid and iron, alloy parts are not included.

(3) Surface high-frequency treatment (also known as induction quenching) : high frequency induction current is applied to quench the substrate surface through rapid heating and rapid cooling. Material: The gear coupling material is steel, especially medium carbon steel, alloy steel, casting and forging products. Quenching thickness should be 0.5 to 5㎜, the operation time is relatively short, the substrate deformation is relatively small. It is also widely used in gear couplings.

(4) nitriding treatment: is a kind of heat treatment process using nitrogen and conditioning treatment combined with effectively improve the overall surface strength of parts, its advantages are high surface strength, overall deformation _ small (0.01mm or so), often used for gear coupling surface strength and elastic write-off coupling strength of the overall improvement.

(5) Electroplating treatment: electroplating treatment principle and characteristics: as a Yin _ gear coupling placed in the plating tank and make the metal film through the direct current in the form of electrolytic deposition on the surface of the substrate. Material: This method is used for metal or plastic substrates. "Electroplating the substrate when the surface of a toothed coupling conducts electricity through a point-free solution", in many cases, some pinholes will be left. For decorative substrates, the surface diameter of the pinhole is less than 1 micron, for _ purpose or industrial substrates, the pinhole diameter is 1 to tens of microns. It is often used in demanding situations.

To sum up:
