From the perspective of the wear of the imported gears, the failure may be caused by the failure of the original machine when the disassembly and assembly process is performed. The seal is not good, and some hard particles (metal scraps, particles, etc.) are mixed or suspended. In the lubricant, in the relative motion of the tooth surface engagement, the tooth surface material is lost or misaligned, so that the gear gradually loses the involute profile, which is proved by the radial scratch on the gear teeth. . Moreover, since the installation accuracy is not handled properly during installation, the tooth surface contact accuracy is not good, and the gear is subjected to high-speed, heavy load and impact load of the Zibo dust collector for a long time. As time goes by, the tooth surface gradually appears. Fatigue pitting corrosion develops to reduce the working surface of the gear teeth and destroy the smoothness of the tooth surface. Under the above two factors, the hardened layer metal of the tooth surface is gradually peeled off by one layer, destroying the normal tooth surface. The shape produces sharp wear until the full teeth are polished.
From the perspective of the wear of domestic gears, there are many reasons. First, there are problems in surveying and mapping. Since the center distance between the gear pairs in foreign countries is non-standard, it is troublesome to determine the gear parameters during the surveying, and the parameter is not suitable directly affects the life of the gear. Secondly, there are problems in material selection and heat treatment. In the original design, 45# steel (or 40Cr) is used for high-frequency quenching, which is not suitable for the gear. The gear is the most stressed in the gearbox, and the rotation speed is the highest, while the diameter and volume are In theory, in theory, the high-speed and heavy-duty teeth during the meshing process, the temperature rise of the meshing zone is too high, so that the viscosity of the lubricating oil is lowered, thereby losing the lubricating effect, causing the tooth surfaces to directly contact, so that the parts are mutually bonded, so that After welding together, and then with the relative movement of the tooth surface, the bond point is plastically deformed and broken, resulting in failure of the glue. Therefore, whether the selected material has good anti-adhesive properties, whether the combination of large and small gear materials is appropriate, whether the hardness of the tooth surface and the depth of the hardened layer are appropriate, whether the surface of the tooth of the Zhangjiagang mill is decarburized, whether there is grain boundary oxidation, crystal image Many factors such as residual stress of the structure can affect the life of the gear. Furthermore, the machining accuracy of the gear is: the tooth direction error can cause the tooth direction to be eccentrically loaded, the circumferential section is deviated, the tooth shape error causes the contact in the tooth height direction, and the tooth surface roughness is liable to cause pitting or gluing failure. Finally, in terms of maintenance, regular inspections are not carried out, and abnormal conditions are not dealt with in a timely manner. If the lubricating oil is not replaced regularly, the failure of the gears can be accelerated.
3. Has a frequency stabilizer and high frequency shielding devices, the
high-frequency interference to a minimum.
4. Manually adjust the mould by the four corners horizontal adjustment, adjust
die easily.
5. Can be automatically completed secondary welding process, improve work
efficiency.
6. Stepless temperature heating system, make work more efficient.
