轮式工程机械变速器和后桥差速器内的轴承磨损严重及滚珠损坏时,需要更换新轴承。由于旧轴承外套残留在壳体内,镶嵌比较紧固,很难取出。为此自制了一种专用拆卸工具,使用起来非常方便。此拆卸工具的具体结构如附图所示。制作过程如下:(1)制作1个一端有端盖的圆柱形钢筒2,在钢筒端盖的中心钻1个直径略大于30mm的孔。 Wheels, mechanical transmission and rear axle differential bearing wear and ball serious damage, the need to replace the new bearings. As the old bearing coat remains in the shell, the mosaic is relatively tight, it is difficult to remove. For this purpose made a special removal tool, very easy to use. The specific structure of this removal tool as shown in the figure. The production process is as follows: (1) Make a cylindrical cylinder 2 with an end cap on one end and drill a hole slightly larger than 30mm in the center of the steel cylinder cap.
