Description

滑动轴承
本发明涉及一种用于轧机的轧辊轴颈的滑动轴承，它包括一个金属制的轴承套和一个安置在该轴承套中的具有锑和铜的锡基滑动轴承合金。
这种轴承多年来是例如作为油膜轴承进行生产的。但是所用的滑动轴承合金比较软，因此它在负荷的作用下容易流动。这种流动使轴承的形状稳定性受到损害，很快就需要用新轴承或者用修理后的轴承更换所用的轴承。此外滑动轴承合金的抗压强度较小。
在公知的滑动轴承合金中也有加入镉的，由此能够提高抗压强度。但是由于含镉的合金有毒，因此尽管它具有提高抗压强度的优点，现在也不使用了。因此还是要应用公知的滑动轴承合金。
文献EP0717121B1中公开了一种滑动轴承合金，它通过添加银和锌而具有较高的顶锻屈服极限和较好的冲击弯曲疲劳强度等优点。这种新合金主要用在涡轮机、压缩机、活塞机和膨胀机中。其优点在于滑动轴承的金属中没有添加有毒的合金成分。但是，这种合金还不能马上用于轧辊轴颈，因为根据该现有技术，合金成分的波动幅度还很大，因此还不能以所希望的方式实现要求的小的流动性和大的抗压强度。
本发明的任务是对一种公知的滑动轴承和一种制造滑动轴承的方法进行改进，使得滑动轴承具有最小的流动倾向和高的抗压强度，由此获得卓越的形状稳定性，从而使轴承具有长的使用寿命。
为此提出了用于轧机的轧辊轴颈的滑动轴承，包括一个由金属制的轴承套和一个安置在该轴承套中的具有锑和铜的锡基滑动轴承合金，其特征在于，滑动轴承合金是由6.8至7.2重量百分比的锑，6.3至6.7重量百分比的铜，0.5至0.7重量百分比的锌，0.05至0.15重量百分比的银和作为剩余成分的锡构成的。
在使用这种滑动轴承合金后，形状稳定性得到大大的改善，抗压强度得到提高。
在制造滑动轴承时，初始层厚为4至7毫米的滑动轴承合金通过离心铸造加工到已被预热的轴承套的内壁上。在完成了离心铸造后以至少每秒0.5度摄氏温度的速度对轴承套进行冷却。
而在此之前，为了获得1.25毫米的最终层厚，8至12毫米的初始层厚是必需的。现在通过减小初始层厚，一方面将大大减少所用的合金材料，从而可以降低轴承的制造成本，另一方面也使要冷却的合金材料大大减少。由此使冷却时间更短，从而获得更理想的结构转变，对轴承材料的形状稳定性和抗压强度起到有利的作用。
此外，在加工滑动轴承时，将初始层厚切削加工到最终层厚时要切削掉的材料很少，从而缩短了加工过程。需要处理掉的切屑产生得较少，加工设备的使用时间较短，因此所受的加工负荷较低。
由于轴承具有极小的流动性和较高的抗压强度，使得轴承在工作中不会容易地和很快地受到磨损，从而有较长的使用寿命。轴承不必经常地进行整修或用新轴承更换。即使在整修时也能使用本发明所述的合金，从而使修理后的轴承也具有小的流动性和高的抗压强度这些优点。
下面对照附图对本发明进行详细说明。附图中示出了一个轴承套1，在轴承套1中加工了一层滑动轴承合金2，该滑动轴承合金2由(按重量百分比计)7％的锑、6.5％的铜、0.6％的锌、0.1％的银和剩余的锡构成，并且是从4至7毫米的初始层厚切削加工成0.5至1.2毫米的最终层厚。
