目前,油膜轴承的设计计算中,都假设轴承的金属零件是刚性的。基于这个假设设计的油膜轴承,在一般条件下是与实际情况相当一致的,但是,当油膜压力高到一定程度后,与实际情况就有明显的差别了。CARL通过实验指出,在油膜压力高于140公斤/厘米~2(2000磅/英寸~2)后,轴承金属零件的弹性变形就不能忽略不计了。在轧机油膜轴承中,由于其负载大,油膜压力值大大超过140公斤/厘米~2,达1000公斤/厘米~2。其负载比压也超过140公斤/厘米~2,达170公斤/厘米~2以上。因此,轴承金属零
At present, the oil film bearing design calculations, assume that bearing metal parts are rigid. Oil film bearings based on this assumption, under normal conditions are quite consistent with the actual situation, but when the oil film pressure to a certain extent, with the actual situation there is a clear difference. CARL has shown through experiments that the elastic deformation of bearing metal parts can not be neglected after the oil film pressure exceeds 140 kg / cm 2 (2000 lb / in 2). In rolling mill oil film bearings, due to its large load, the oil film pressure value greatly exceeds 140 kg / cm ~ 2, up to 1000 kg / cm ~ 2. Its load than the pressure is also more than 140 kg / cm ~ 2, up to 170 kg / cm ~ 2 or more. Therefore, bearing metal zero
