轮胎是最终承受农业机械全机重力的惟一部件,长久使用后可以反映出农业机械的有关工况,故可透过观察轮胎不同部位的磨损情况,判断出农业机械的有关机构是否存在故障。1.两肩磨痕轮胎两肩磨损较严重说明轮胎经常在低气压下工作。气压低可直接导致轮胎接地部分变宽、中部略向上拱起,从而造成胎冠两肩着地磨损;轮胎在变形时,胎体的温度会异常地升高,当农业机械的行驶速度过快或 Tires are the only components that will ultimately withstand the full weight of agricultural machinery. After long-term use, they can reflect the conditions of agricultural machinery. Therefore, we can observe the wear and tear of different parts of the tire to determine whether there are any faults in the agricultural machinery. 1. Shoulder wear marks more serious wear and tear on both sides of the tire Tire often work under low pressure. A low air pressure leads directly to a widening of the tire’s grounded area and a slight upward arching of the center, resulting in wear of the crown on both shoulders. When the tire is deformed, the temperature of the carcass rises abnormally. When the agricultural machinery runs too fast or
