三峡工程连续梯级船闸，水头高，启闭频繁，且为多级船闸，彼此互相影响，因此，要求船闸反弧门轴承承载力大、耐磨性好、可靠性高。通过摩擦对比试验，测定了ＧＹ－５０ 与ＴＳ－７０ 两种固体自润滑轴承的摩擦系数、稳定磨损率。试验结果表明，ＴＳ－７０ 轴承摩擦系数小，耐磨性好，其使用寿命可满足在三峡工程中至少使用三年的设计要求。 Three Gorges Project continuous cascade lock, head high, opening and closing frequent, and multi-stage shiplock, mutual influence each other, therefore, required lock ship anti-arc door bearing capacity, good wear resistance, high reliability. By friction contrast test, the friction coefficient and the steady wear rate of two solid self-lubricating bearings GY-50 and TS-70 were measured. The test results show that, TS-70 bearing friction coefficient, wear resistance, and its service life to meet the Three Gorges Project at least three years of design requirements.
