一、平衡臂轴套拆装工具东方红54/75拖拉机支重台车的平衡轴套,受载很大,使用中内圆逐步磨损。当大轴套与台车轴和小轴套与摆动轴的间隙超过一定尺寸,必须更换轴套。大小轴套外径均为静压配合(过盈量为0.34～0.55毫米)。运行中经常接触泥水,易锈蚀,拆装不方便且劳动强度大。为此,我们制作了简易工具如图1所示,用来拆装上述轴套,效果很好。 First, the balancing arm sleeve disassembly tool Dongfanghong 54/75 tractor balance trolley sleeve, a large load, the use of internal wear gradually. When the gap between the large shaft sleeve and the trolley shaft and the small shaft sleeve and the swing shaft exceeds a certain size, the shaft sleeve must be replaced. The size of the sleeve outer diameter is static pressure fit (interference amount of 0.34 ~ 0.55 mm). In the operation, mud and water are often touched, and it is easy to rust. It is inconvenient to disassemble and disassemble, and labor intensity is great. For this reason, we have made a simple tool as shown in Figure 1, which is used to disassemble and disassemble the above sleeves, and the effect is very good.
