国产的煤水車車輪輪箍,从近来装車使用的运轉情况看来,发現輪箍耐剝离性能尚不能滿足用戶要求。但由于煤水車輪箍直徑較小,而在运用中負荷却較大,不均勻,因此易产生疲劳剝离。近几年来,煤水車輪箍发生剝离情况愈来愈多,每年镟修量和換輪量亦大。所以有必要設法提高煤水車輪箍强度和硬度,以减少其在运用中产生剝离。
Domestic coal-water wheel wheel tires, loading operation from the recent use of the situation seems to find that the wheel tire resistance to peel performance is not yet able to meet user requirements. However, due to the smaller diameter coal wheel tires, while in use, but the load is large, uneven, so prone to fatigue stripping. In recent years, there has been more and more stripping of the wheel hub of coal water, and the amount of repairs and wheel changing is also large every year. Therefore, it is necessary to try to improve the strength and hardness of coal wheel rim to reduce its peel in use.
