更换轴承时,如果轴承拆装不当,会造成轴承及拆卸部件表面损伤,既增大劳动强度又造成材料浪费。为此,自制一套专用工具。该工具由支架、横梁、螺杆、螺母、垫片、拉板等组成。拆卸轴承时,先将拉板7倾斜着放入轴承内并拉紧,然后用扳手稳住螺杆4,旋动螺母5即可将轴承9拉出(见图1)。压装轴承时,将螺杆4端部换装一个带耳螺钉3,借助轴2端部螺纹孔固定,
When replacing the bearing, if the bearing is improperly disassembled, the surface of the bearing and the disassembled part will be damaged, which will not only increase the labor intensity but also cause the material to be wasted. To do this, make a special set of tools. The tool from the stent, beams, screws, nuts, gaskets, pull plate and other components. When disassembling the bearing, tilt the pull plate 7 into the bearing first and tighten it, then hold the screw 4 with a wrench and pull out the bearing 9 by turning the nut 5 (see Figure 1). When the bearing is press-fitted, the end of the screw 4 is replaced with an ear screw 3, and the end of the shaft 2 is fixed with a threaded hole,
