详细说明:本专利叙述转炉耳轴的自由轴承,它具有以下特征:可以适应耳轴由于荷重和倾动等而产生的挠曲变形,并且可以防止杂物或灰尘进入轴承内部。而这些特征对于承受1000吨以上荷重的、并经常受到高温和灰尘影响的转炉轴承则是很重要的。图1中,1转炉,2托圈,3、4耳轴,M_1及 M_2为自由轴承5和固定轴承6的中心线与耳轴3、4的中心线7的交点,当耳轴受热产生挠曲变形时,其变形偏移的中心线为 Description: This patent describes the converter trunnion free bearing, which has the following characteristics: It can adapt to the trunnion due to load and tilt and other deflection and deformation, and can prevent debris or dust inside the bearing. These features are important for converter bearings that withstand more than 1,000 tons and are often exposed to high temperatures and dust. In Fig. 1, 1 converter, 2 circles, 3, 4 trunnions, M_1 and M_2 are the intersection of the center line of the free bearing 5 and the fixed bearing 6 with the centerline 7 of the trunnion 3, 4, When the curve is deformed, the centerline of the deformation offset is
