大棚卷帘机输出轴漏油是困扰用户多年的难题，通过分析漏油原因，认为是老式油封盖没有定位结构，油封与轴不同心，使得油封与轴压力不均匀，一边紧、一边松，松边漏油、紧边磨损大，减少了使用寿命。
The oil leakage of the output shaft of the canopy roller shutter is a problem that has puzzled the users for many years. By analyzing the causes of the oil leakage, it is believed that the old oil seal cover has no positioning structure, and the oil seal and the shaft are not concentric, which makes the pressure between the oil seal and the shaft uneven, tight and loose at the same time, loose edge oil leakage and tight edge wear are large, reducing the service life.
对油封盖结构进行改进，增加定位直口，并把油封改在外侧，方便油封更换，通过技术改进解决了输出轴漏油的老大难问题。
The structure of the oil seal cover is improved, the locating straight port is added, and the oil seal is changed on the outside to facilitate the replacement of the oil seal. The old and difficult problem of the oil leakage of the output shaft is solved through the technical improvement.
