The role played by the wear nylon rod field. Nylon rod is used as an auxiliary material to use, we know that a lot of machinery and equipment or large production tools nylon rods will need to wear-resistant material, which gives the nylon rod broadens the area: one with in the manufacture of metal wear parts wear-resistant materials include steel, composite steel and cast iron. High manganese steel is a long history of anti-friction material nylon rod models, under harsh working conditions, not prone to plastic instability, and has a very good abrasion resistance. Second, only the impact load and unit pressure greater abrasive wear conditions, resulting in work hardening effect, it shows more than other materials with excellent wear resistance. Impact load is not too large for easy wear parts, the current low cost of more extensive selection of non-alloy steel (carbon steel) or in high-carbon steel, and to take certain measures to improve the wear resistance technology. Selection of hardened steel or composite steel production parts, in terms of performance wear and impact resistance, etc. have obvious advantages, can improve the service life, but costly. . The new nylon rod couplings are included. The new couplings originally applied at a higher speed wire rod mill, then gradually extended to the row-style mini-mill. The advantage of this coupling are: simple structure, easy handling, long life, smooth operation, allowing large dip 5-6 times faster than ordinary cylindrical rod pin coupling. Drum nylon rod nylon rod pin coupling parameters for speed and negative I changes, frequent starting speed higher (gross 20 m / s) of transmission. Especially for a strong shock and vibration loads of small and medium sized rolling mill main drive. Now I plant design and application of a drum-shaped nylon rod pin coupling described below. Certain gap to compensate for machine-foot columns and roll axial deviation and deviation caused by the tilt axis; the outer surface of the shaft of the drum-shaped surface, and coat the radial clearance of about 1 mm. Also nylon rods enterprises, in order to achieve axial positioning of the coupling in both ends of the central portion of the shaft is equipped with a spherical head, respectively, with the roll top tight end faces, one end of the spring head, can absorb axial impact and vibration during operation .
