Determination Method Of Timken Bearing Replacement

Timken Bearing Replacement

The specific judgment method of whether Timken bearing should be reported for repair, that is, Timken Bearing Replacement the specific judgment method of Timken bearing has been fully utilized and near damage is as follows:

1) Using Timken bearing working state monitoring instrument

It is a convenient and reliable method to judge the working state of Timken bearing and decide when to report for repair by using such instruments as Timken Bearing Replacement Ferrograph or SPM or i-id-1 Timken bearing working state monitoring instrument.

For example, when HD-1 instrument is used, when the pointer approaches the dangerous area from the warning Timken Bearing Replacement area, and the pointer does not return after taking measures to improve lubrication,

it can be determined that it is the problem of Timken bearing itself. At this time, the Timken bearing can be reported for repair before entering the dangerous area. How far away from Timken Bearing Replacement the dangerous area to start the repair can be adjusted by experience.

Using such an instrument, we can make full use of the working potential of Timken bearing, report Timken bearing for repair in time, and avoid Timken Bearing Replacement faults. It is and economical.

Determination Method Of Timken Bearing Replacement

2) Monitor with simple tools

In the absence of the above instruments, the operator can hold a round bar or wrench and other tools to collide with the machine shell close to the Timken bearing, shame his ears Timken Bearing Replacement on the tool and listen for the sound of the Timken shaft transmitted by the tool. Of course, it is also possible to refit the medical stethoscope.

The normal Timken shaft rotation sound should be uniform, stable and not harsh, while the abnormal Timken shaft rotation sound has a variety of intermittent, impact or harsh sounds. First, get used to the normal Timken shaft carrying sound, and then you Timken Bearing Replacement can grasp and judge the abnormal Timken shaft carrying sound.

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

When the large SKF Bearing

is installed into the disassembly sleeve, 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 Timken Bearing Replacement 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 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 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 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 the pressure of the oil pressure gauge in the pipeline, The thrust of SKF Bearing can be roughly judged.
