Yantai Bearing, Yantai...Slewable Bearing - ! / , -First, disassembly of the bearing periphery
< / , -: - ! / , -Disassemble the outer ring of the interference fit, and install it in the outer shell in advance Set several screws on the circumference of the outer ring to squeeze the screw, and tighten the screw evenly on one side. While disassembling. These screw holes are usually covered with blind plugs, separable bearings such as tapered roller bearings, and several cuts are set on the housing shoulders. At this time, gaskets are used, and then they are disassembled with a press or slowly disassembled by tapping them.
< / , -: - ! / , -Second, disassembly of cylindrical bore bearings
< / , -: - ! / , -When disassembling the inner ring, you can actually use a press to disassemble it It's easiest to pull it out. At this time, attention should be paid to allowing the inner ring to withstand its pulling force. The inner ring of large automobile bearings is disassembled using the hydraulic method. Oil pressure is applied through the oil hole provided on the shaft to make it easy to pull out. For large-width bearings, the hydraulic method and the drawing fixture are used together for disassembly. Induction heating can be used to disassemble the inner ring of type and type cylindrical roller bearings. This is a method of heating a local area in a short period of time to expand the inner ring and then drawing it.
< / , -: - ! / , -Third, disassembly of tapered bore bearings
< / , -: - ! / , -When disassembling small bearings with adapter sleeves, it is necessary Tighten the supporting inner ring on the bearing, then turn the nut back several times, and use a spacer or hammer to knock it out.
