Abstract

Super wear-resistant cast nylon pulley and its processing method. The present invention relates to a polymer material-nylon 6, and also relates to a method for processing the pulley from this material. The technical solution of the invention is: the weight ratio of caprolactam, accelerator and curing agent in the material is 1000:1.2-1.6:3-4. The present invention has the following characteristics: 1. Small density, light weight, small inertia and stable operation; 2. Excellent mechanical properties, high strength, high rigidity, good toughness, creep resistance, impact resistance, high shape stability, and can Steel pulleys are completely interchangeable. 3. Good wear resistance and self-lubricating performance. 4. Oil resistance, corrosion resistance, no rust, 5. Good shock absorption performance, no noise.

Description

technical field

[0001] The present invention relates to a polymer material-nylon 6, and also relates to a method for processing the pulley from this material. Background technique

[0002] Traditional pulleys mostly use cast iron or steel, which have poor wear resistance and are heavy. During work, they are easy to damage the steel wire rope. When they rub against the steel wire rope, a lot of heat will be generated, which will reduce the service life of the supporting parts. Contents of the invention

[0003] Aiming at the above problems, the present invention provides a cast nylon pulley made of polymer material—nylon 6 and a processing method thereof.

[0004] The technical solution of the invention is: the weight ratio of caprolactam, accelerator and curing agent in the material is 1000:1.2-1.6:3-4.

[0005] The accelerator is sodium metal, sodium alkoxide, sodium hydroxide or sodium carbonate.

[0006] The curing agent is acetyl caprolactam.

[0007] The curing age...
