Bearing steel steel collar effect

The main wear forms of the steel failure are adhesive wear and fatigue wear. As the overall hardness of the bearing steel is above HV800, the hardness is high and the wear is small, and it exhibits excellent performance in anti-sticking wear and fatigue wear. We from the beginning of the beginning of every six months on the bearing steel steel collar for a spot check, with the flash tachometer on the operation of the bead to observe and found that the wire ring running smoothly, running the track smooth, very few flying ring phenomenon, Steel collar surface smooth, no sticky material, also found no signs of decline. The general steel collar in the run-in period, especially after 10 months of operation, the phenomenon of wedge ring, fly ring increased, steel runway and the edge of the irregular wave pattern and point peeling, this phenomenon with the use of time to extend Further deterioration, often leading to cotton yarn yarn defects, seriously affecting the quality of yarn.
Bearing steel steel collar wide applicability, different types of fiber and the number can be used, the configuration of the bead ring and ordinary flat steel collar the same. The steel surface is smooth, the deformation is small, the roundness, the flatness, the parallelism and so on are superior to the ordinary flat steel collar, the running circle of the wire ring is smooth, the spinning tension is stable, the thousand head decapitations and the hairiness indexes can control Good level. Bearing steel collar and ordinary flat steel collar spinning comparison in Table 1.
Ordinary flat steel collar life is generally about 14 months, and every three months or so to be under the machine grinding maintenance, frequent replacement, each replacement of a new steel collar have a run-in period, in the run-in period of spinning tension is not Stable, yarn hairiness serious, broken more than the value of the work of labor intensity. Bearing steel steel collar after the car without maintenance, one-time continuous use up to three years or more, no need to polish the machine, only special staff regular checks, in a relatively long period of time to maintain production and quality stability.
Bearing steel collar wear resistance, long life, cost-effective. Bearing steel collar price is only about 1.6 times the ordinary flat steel collar, and the service life of ordinary flat steel collar about 3 times. The use of bearing steel is conducive to the stability of the quality of spinning, while reducing the consumption of equipment for enterprises to save money and reduce production costs.
