Disassembly of the tapered bore rolling bearing 1. Disassemble the spherical roller bearing with the adapter sleeve. Use a metal rod to remove the inner ring of the bearing from the sleeve.
2, the self-aligning ball bearing with the adapter sleeve removed. Use the normal tubular to avoid bearing damage.
3. Disassemble the push-off sleeve 4 with a compression nut, and disassemble the bearing by means of a nut and an inference bolt to tighten the gasket next to the inner ring.
5. Disassemble the push-out sleeve with hydraulic nut. Support the outstanding push-out sleeve with thick-walled ring.
6. Disassemble the spherical roller bearing from the push-off sleeve by hydraulic method. Press the oil into the cooperation appearance; the push-off sleeve will pop up. The nut should be left on the shaft.
The bearing fixed by the push-off sleeve is disassembled with the compression nut. However, when the large bearing is disassembled, a large force is required; at this moment, the thrust bolt can be used in cooperation with the compression nut; and between the inner ring of the bearing and the bolt Take a washer.
The hydraulic nut is used to push the sleeve to disassemble the bearing; the process is simple; the economy is good. The hydraulic method is used to disassemble the large-scale bearing, which makes the disassembly very simple. Just press the oil to the cooperation appearance; the cooperation piece will be It is easily separated without the risk of external damage.
It is necessary to have oil grooves and oil holes on the conical shaft. The oil injector can meet the pressure.
It is necessary to pre-process the oil groove or oil hole on the large adapter sleeve or the withdrawal sleeve. The oil pressure required for disassembly is required by the oil pump.
The viscosity of the disassembled oil is 150mO/s at 20 ° C. Adding a rust remover to the oil can dissolve the cooperating corrosion.
For tapered bore bearings; simply press the oil into the cooperating surface. Because the tight cooperation will be loosened; therefore, the obstruction equipment like a nut is used to restrain the movement of the bearing.
