In order to reduce the yarn hairiness, reduce the yarn breakage, extend the ring exchange cycle and reduce the production cost, the steel ring traveler is the key equipment for the winding part of the ring spinning frame. Trial steel bearing collar. We have carried out follow-up observation and testing on the spinning performance of the bearing steel ring, found that it has a long service life, stable operation and high cost performance. Now, it is gradually replacing the ordinary flat steel ring that has reached the service life with the bearing steel ring . The main wear forms of ring failure are sticking wear and fatigue wear. Due to the overall hardness of bearing steel ring reaching above HV800, its hardness is high, the wear is small, and both the anti-adhesion wear and fatigue wear performance are superior. We start from the beginning of every six months to conduct a random inspection of bearing steel ring, with a flash gun velocimeter to observe the operation of the situation and found that the smooth movement of the traveler, smooth orbit, very few fly-circle phenomenon, at the same time, The ring's surface is smooth, non-sticking and no sign of recession is found. The normal ring in the run-in period, especially after 10 months of operation, there wedge traveler phenomenon, the ring increased, the ring runner and the edge of the irregular wave pattern and punctate spalling, this phenomenon with the use of time and Further deterioration, often resulting in cotton yarn defects, seriously affecting the quality of yarn. Wide range of bearing steel collar applicability, different types of fibers and numbers can be used, the configuration of traveler is the same as ordinary flat steel collar. The ring surface is smooth, small deformation, roundness, flatness, parallelism and so are superior to ordinary flat steel ring, traveler orbit unobstructed, spinning tension stable, broken when the 1000-spindle, hairiness index can be controlled in the more Good level. Bearing steel ring and ordinary flat-necked spinning contrast Table 1. General life of flat-shaped steel ring is generally about 14 months, and every three months or so on the need to take off the machine grinding and maintenance, frequent replacement, each replacement of the new ring has a run-in period, during the run-in period tension is not spinning Stable, serious yarn hairs, broken ends, the value of labor-intensive car workers. Bearing steel ring after the car without maintenance, one-time continuous use of up to three years or more, without the next grinding machine, only parts of staff regular checks, in a relatively long period of time to maintain the stability of production and quality. Bearing steel collar wear resistance, long life, cost-effective. The price of bearing steel ring is only about 1.6 times that of ordinary flat steel collar, while the service life is about 3 times that of ordinary flat steel collar. The use of steel bearing steel ring is conducive to the stability of the quality of the spinning, while reducing equipment consumption, saving money for the enterprise, reducing production costs.
