通航船闸人字闸门的底枢,由固定于船闸底部的设有不锈钢蘑菇头底座、及固定于闸门门扇上的设有青铜轴瓦的顶盖组成。这种底枢工作不能令人满意的主要原因之一是,磨擦面均匀灌注润滑脂十分困难。若不满足这一要求,将会形成于磨擦区,从而致使磨擦面严重磨损。在人字闸门底枢新结构中,顶盖轴瓦采用钢结构,并在其上敷设氟塑料制成的厚约2mm的φ4KI5M5 3号薄膜耐磨。这种材料作为固体润滑脂,装在轴瓦的球形凹部。安装在底座上的蘑菇头,仍和以前一样,
The bottom pivot of the navigable lock Miter gate is composed of a stainless steel mushroom head base fixed on the bottom of the lock and a top cover provided with bronze bushings fixed on the gate leaf of the gate. One of the main reasons for this unsatisfactory bottoming job is that it is very difficult to evenly grease the friction surface. If you do not meet this requirement, will be formed in the friction zone, resulting in severe wear on the friction surface. In the Miter gate at the end of the new structure, the roof bearing steel structure, and on which the laying of fluorine plastic made of about 2mm φ4KI5M5 3 wear-resistant film. This material as a solid grease, mounted on the spherical concave spherical bearing. Mushroom head mounted on the base, still the same as before,
