一、建议轴承间隙规定在0.10毫米以下东方红—75中央传动螺旋锥齿轮,受载后产生很大的轴向力,需用圆锥滚子轴承来承受,并通过轴承盖和紧固螺钉作用到壳体上。变速箱二轴(以下简称二轴)前端安装有双排27709轴承,用来承受轴向力和径向力,后端有2712K圆柱滚子轴承;只承受径向力。后桥轴左、右分别安装有7612和7312圆锥滚子轴承,同时用来承受轴向力和径向力。圆锥滚子轴承在装配时,应该有适当的预紧度。这样,可以提高支承刚度,改善圆锥滚子承载性能;轮齿受载以后,轴向弹性变形
First, the proposed clearance of the provisions of 0.10 mm below the East Red-75 central drive spiral bevel gear, the load generated after a great axial force, the need to use tapered roller bearings to bear and through the bearing cap and fastening screws to the role of On the shell. Transmission shaft (hereinafter referred to as two-axis) front-mounted double row 27709 bearings used to bear the axial force and radial force, the rear 2712K cylindrical roller bearings; only radial forces. Axle left and right were fitted with 7612 and 7312 tapered roller bearings, at the same time used to withstand axial and radial forces. Tapered roller bearings in the assembly, there should be appropriate preload. In this way, the support stiffness can be increased and the bearing performance of the tapered roller can be improved; after the tooth is loaded, the axial elastic deformation
