The two sides of the wheel and the bearing sleeve are fixed and cooperated with the bearing. The self-propelled end bearing has high temperature; the oscillating value is high; the bearing åŒ upper cover is removed; the manual slow reverse fan is found; Azimuth bearing rollers; there is also a rollover condition in the non-load zone. In this way, it can be concluded that the bearing working gap changes too high and the device gap can be lacking. It is known that the internal clearance of the bearing is only 0. 04mm, and the transuranium has a partial pain of 0.08mm, because the left and right bearing spans are large; Or the bearing device's point of view error is difficult; therefore; large fans use a spherical roller bearing that can be actively adjusted, but when the internal clearance of the bearing is lacking. The internal rolling part of the bearing is restrained by the moving space; its active centering function is affected; the oscillation value will increase instead. The internal clearance of the bearing decreases with the increase of the cooperation tightness.

2, sweeping methods:
When disposing; retract the adapter sleeve; adjust the cooperation tightness between the shaft and the inner ring from the beginning; take the gap after replacing the bearing to take 0. 10mm. Start the fan from the end of the head device; the bearing oscillation value and working temperature are all normal.
The internal clearance of the bearing is too small or the manufacturing accuracy of the machine parts is unsatisfactory; both are the main reasons for the high working temperature of the extension bearing; for the convenience of the device, disassembly and protection of the fan equipment. Usually, the bearing housing bearing with the inner ring of the tapered sleeve bearing hole is usually used in the drawing; however, it is also easy to cause problems due to the negligence of the device program. Especially the proper clearance of the gap. The internal clearance of the bearing is too small. The working temperature rises rapidly: the inner ring cone of the bearing cooperates with the tightening sleeve too loosely; the bearing is easy to burn in the short term due to the loosening of the cooperation surface.
