Variable camber sliding bearing containing three oil wedges

[0021] Figures 3 and 4 show the structure and specific examples when the rotating shaft needs to be forward and reversed. In Figure 3, φ 0 Is the diameter of the shaft, φ 1 Is the outer diameter of the bearing bush, φ 2 Is the inner diameter of the bushing, R is the radius of curvature of the inner surface of the bush, and the arrow of n indicates the direction of rotation of the shaft. The bearing bush is divided into three parts at 120°, each part is 10° as a section, the inner surface of the bearing bush has a radius of curvature R in the first 60° range, and each section changes from the largest to the smallest in turn, and in the rear 60°. , Each section changes from the smallest to the largest in turn, and the gap between the shaft and the bearing bush also changes accordingly. The R value shown in Figure 3 and Figure 4 is the change of the first 60°, R 7 Is the radius of the bearing shell at the maximum clearance, R 1 Is the radius of the bearing shell at the minimum clearance
