Carbon steel Black phosphated Normal straight profile precision worm.
Description
Generally, a worm and a shaft are made into one body, which is called a worm shaft. The structure of the worm gear can be divided into three forms.
①Integral type: used for cast iron and bronze worm wheels with small diameters.
②Press-fit type of gear ring: the hub is cast iron or cast steel, and the rim is bronze.
③ Bolt connection type: the wheel flange and the hub adopt reamed holes and are connected by bolts. This structure is convenient for assembly and disassembly.
Advantages of the black phosphating process
1. The process is easy to control, stable in quality and low in cost.
2. The phosphating film has uniform crystals, compactness, good corrosion resistance, uniform dark black appearance, and good decoration.
3. For different materials and heat treatment methods, the color consistency is good, and the product quality is stable.
4. Low phosphating temperature, short time and high production efficiency.
5. Non-toxic substances are discharged during the production process, which is conducive to the treatment of the three wastes.
6. The black phosphate film has excellent anti-friction properties (that is, reducing the friction coefficient and reducing friction resistance), wear resistance, good insulation, heat absorption and heat resistance.
