Characteristics of screw shaft in charcoal machine equipment
The spiral shaft of the charcoal machine is a very important part of the charcoal machine equipment. It is the key to making mechanism charcoal. The quality of the spiral shaft is related to the stable production of the whole charcoal machine equipment. Features can make the charcoal machine maintain a stable and good operating state.rn
The screw shaft of the charcoal machine must first have high strength. Due to the combined effects of compression, torsion and bending of the screw shaft when it is in operation, especially when the hard shaft such as material "ring knot" or metal jams the screw shaft, if the power cannot be cut off immediately, huge stress will be generated in the screw shaft. Therefore, it is required that the screw shaft should have high strength.rn
The spiral shaft of the charcoal machine also needs to have high wear resistance. The friction between the material and the surface of the spiral shaft during work, especially the head of the spiral shaft will cause great frictional resistance. It is required to have a strong ability to resist abrasive wear. This requires the improvement of material density and surface hardness. If the surface hardness reaches Vickers hardness, the wear resistance of the screw shaft will be greatly improved.rn
The spiral shaft of the charcoal machine also needs to have high heat resistance. When the spiral shaft is working, in order to make the loose materials condense and form, the temperature of the materials is often maintained between 140 degrees Celsius and 160 degrees Celsius. Therefore, when the screw shaft material is required to work at least 300 degrees Celsius, the mechanical properties are not changed, that is, high strength and high hardness are maintained.
