Correct Disassembly And Replacement Of Ina Bearing

Correct Disassembly 

1. Ina bearing cup removal

Remove the outer ring of the interference fit. Set several outer ring extrusion screws on the circumference of the shell in advance. Tighten the screws equally while removing. These screw holes are usually covered with blind plugs, tapered roller ina bearings and other separated ina bearings. Several cuts are set on the housing shoulder. Use cushion blocks, disassemble with a press, or knock gently.

2. Disassembly of cylindrical bore INA Bearing in INA Bearing

The inner ring can be easily removed by pressure machinery. At this time, pay attention to make the inner ring Correct Disassembly bear its pulling force. The inner ring of large ina bearing is disassembled by oil pressure method.

Oil pressure is applied through the oil hole arranged on the shaft to make it easy to pull out. The INA Bearing with large width is disassembled by the combination of oil pressure method and drawing fixture. The inner ring of Nu and NJ cylindrical roller ina bearings can be removed by induction heating. It is a method of drawing after heating part in a short time to expand the inner ring.

3. Disassembly of taper hole bearing in ina bearing disassembly of relatively small INA Bearing with tightening sleeve, support the inner ring with the stop fastened on the Correct Disassembly shaft, turn the nut back several times, and knock it with a hammer with a cushion block.

For large bearings, it is easier to disassemble them by oil pressure. Pressurize the oil in the oil hole on the taper hole shaft to expand the inner Correct Disassembly ring and disassemble the INA Bearing. In operation, INA Bearing may come out suddenly. It is better to use the nut as a stop.

The specific judgment method of whether ina bearing should be reported for repair

that is, the specific judgment Correct Disassembly method of near damage of INA Bearing has been fully utilized is as follows:

1) Use ina bearing working condition monitoring instrument, such as Correct Disassembly Ferrograph or SPM or i-id? Type 1 ina bearing working state monitoring instrument is a convenient and reliable method to judge the working state of INA Bearing and decide when ina bearing should be reported for repair. For example, when using HD?

For type 1 instrument, when the pointer approaches the dangerous area from the warning area, and the pointer does not return after taking measures to improve lubrication, it Correct Disassembly can be determined that it is the problem of INA Bearing itself. At this time, the ina bearing can be reported for repair before entering the dangerous area.

How far away from the dangerous area to start the repair can be Correct Disassembly adjusted by experience. Using such an instrument, we can make full use of the working potential of INA Bearing, report the INA Bearing for repair in time, and avoid faults. It is and economical.

2) Use simple tools to monitor. When the above instruments are not available, the operator can hold a Correct Disassembly round rod or wrench and other tools to collide with the machine shell close to the INA Bearing, shame his ears on the tool and monitor the ina shaft sound transmitted by the tool. Of course, it is also possible to refit the medical stethoscope.

The normal ina shaft running sound should be uniform, stable and non harsh, while the abnormal ina shaft running sound has a variety of intermittent, impact or harsh sounds. First, get used to the normal bearing running sound, and then you can grasp and judge the abnormal ina shaft running sound.

Then, through the accumulation of practical experience, you can further analyze what kind of abnormal sound corresponds to what kind of INA Bearing abnormal phenomenon. Ina bearings have many types of abnormal sounds, which are difficult to speak and mainly rely on experience.
