经多年使用,我们发现C—11联结器有以下缺点: 1.由于封闭不好,润滑油流失严重,加之尘土飞扬,对润滑非常不利; 2.铸铁轴套与轴同时磨损,甚至铸铁套碎裂; 3.由于铸铁轮毂及套吸震能力差,导致联结器轴容易弯曲; 4.修复困难,损坏后配制新件,成本增加。为了解决上述问题,我们改制了一种新的轮毂,经使用性能良好(图1)。 After years of use, we found that the C-11 coupling has the following disadvantages: 1. Due to poor sealing, the loss of lubricating oil is serious, and dusty, very negative lubrication; 2. Cast iron sleeve and the shaft wear at the same time, Crack; 3. As the cast iron hub and sleeve shock absorption capacity is poor, resulting in coupling shaft easy to bend; 4. Repair difficulties, damaged after the preparation of new parts, the cost increases. In order to solve the above problems, we have adapted a new type of wheel hubs and used them well (Figure 1).
