How To Disassemble Ina Bearing Scientifically

Disassemble Ina Bearing Scientifically

The disassembly of ina bearing is a regular maintenance, which is carried out when ina bearing is replaced. After disassembly, if you continue to use or need to check the state of INA Bearing, the disassembly shall be carried out with the same care as during installation. Pay attention not to damage the parts of INA Bearing, especially the disassembly of interference fit INA Bearing, which is difficult to operate.

It is also very important to design and make disassembly tools according to needs. During disassembly, the disassembly method and sequence shall be studied according to the drawings, and the matching Disassemble Ina Bearing Scientifically conditions of INA Bearing shall be investigated, so as to ensure the safe disassembly operation.

For the removal of the outer ring and the outer ring with interference fit, several outer ring extrusion screws Disassemble Ina Bearing Scientifically are set on the circumference of the shell in advance, and the screws are tightened equally while being removed.

These screw holes are usually covered with blind plugs, tapered roller bearings and other separated Disassemble Ina Bearing Scientifically ina bearings. Several cuts are set on the cover shoulder of the shell. Use cushion blocks, disassemble with a press, or knock gently.

The inner ring can be easily removed by a press. At this time, pay attention to make the inner ring bear its pulling force. In addition, most of the pulling fixtures shown are also used. No matter what kind of fixture, it must be firmly clamped on the side of the inner ring. Therefore, it is necessary to consider the size of the shaft shoulder, or study the processing of the upper groove at the shoulder in order to use the drawing fixture.

How To Disassemble Ina Bearing Scientifically

The inner ring of large ina bearing is disassembled by oil pressure method.

Oil pressure is applied through the oil hole set in ina bearing to make it easy to pull out. The INA Bearing with large width is disassembled by the Disassemble Ina Bearing Scientifically combination of oil pressure method and drawing fixture.

The inner ring of Nu and NJ cylindrical roller bearings can be disassembled by induction heating method. It is a Disassemble Ina Bearing Scientifically method of drawing after heating part in a short time to expand the inner ring. Induction heating is also used when a large number of ina bearing inner rings need to be installed.

When the large SKF Bearing is installed into the disassembly sleeve, Disassemble Ina Bearing Scientifically it can not only greatly save labor, but also is especially suitable for occasions where the position is limited and large hook wrench cannot be used. The specific operations are as follows: place the hardened gasket s at the end of the disassembly sleeve, gently tighten the nut m,

and then evenly tighten the hardened bolts K evenly distributed along the circumference until the required clearance reduction is obtained. Since the disassembly sleeve is self-locking by the friction of its conical surface, it will not loosen even if the compression device is removed. In this way, the compression nut M can be safely removed and replaced with a fixed nut to compress the disassembly sleeve.

During installation, a very thin layer of lubricating oil must be coated on the mating surface of the return sleeve to reduce friction and facilitate installation. However, be careful not to apply thick oil, otherwise the disassembly sleeve will lose its self-locking ability. When the compression screw and nut are removed to replace the fixed nut, the disassembly sleeve will loosen and deviate from the set position, resulting in installation error.

In addition, in the working process, the lubricant will gradually be squeezed out or escape from the fitting gap, resulting in the loosening of the original interference fit of SKF Bearing. When the installed SKF Bearing is removed and then installed on the journal, the nut cannot be screwed to the original position as it is, because the original fit of the SKF Bearing System has become loose after a long time of work,

which is due to the gradual loosening of the thread, the permanent deformation of the fitting surface due to pressure, and certain wear due to friction. In this case, the radial Disassemble Ina Bearing Scientifically clearance reduction, axial thrust or expansion must be re measured during installation.

For large bearings, SKF is more convenient for disassembly and installation.

For all standard disassembly sleeves and threaded shaft ends, the SKF Bearing can also be installed on the conical journal with piston hydraulic Disassemble Ina Bearing Scientifically nut, or the disassembly sleeve can be pressed into the predetermined position of the cylindrical journal. The composition and working principle of the piston hydraulic nut are as follows:

with the help of the manual oil pump, the pressure oil pressure is fed into the oil cylinder (nut) through the high-pressure hose, the oil cylinder is fixed on the threaded shaft end with its Disassemble Ina Bearing Scientifically internal thread, the extended end of the piston is pushed on the end face of the inner ring of the SKF Bearing,

the pressure oil drives the piston to push the SKF Bearing forward along the conical journal, and according to Disassemble Ina Bearing Scientifically the pressure of the oil pressure gauge in the pipeline, The thrust of SKF Bearing can be roughly judged.
