油膜轴承作为一种典型轴承结构在各种外圆磨床上使用得很广。考虑到过去使用的油膜轴承,结构参数k=b/B—0.39不是最佳值[1][2]。为此我们根据k=0.41的最佳条件[2],提出了偏心夹具主要尺寸的计算公式(b——出口油到油膜支承中心线的弧长,B——油膜全弧长)。 油膜轴承轴瓦(图1)背 Oil film bearings as a typical bearing structure in a variety of cylindrical grinding machine used widely. Taking into account the oil film bearings used in the past, the structural parameter k = b / B-0.39 is not optimal [1] [2]. For this reason, according to the optimal condition of k = 0.41 [2], the calculation formula of the main dimensions of the eccentric jig (b - the arc length from the outlet oil to the oil film centerline and B - the full arc length of the oil film) is proposed.
