Wheel bearing force: roller skating wheel bearing installation

Crack defects phenomenon: some gaps and cracks, measures: improve installation and usage; Prevent mix; If caused by metal, it must check other parts. Low friction coefficient, steel rolling body excessive rolling solid pollutants, due to plastic deformation, will be in the race and rolling elements have bump is formed on the edge of the indentation. Outer insulation bearing code VL insulation bearing inner ring code VL, overall dimensions and the basic technical features of insulation bearing with the insulation bearing the same, so you can swap. The choice of tolerance zone equivalent radial load P is divided into 'light', 'normal' and 'heavy' load several ways, such as its ties with dynamic load rating of bearing C for: light load P or less. Superfinishing with oil stone quality is bad, the installation position is not correct; , what is the bearing steel bearing steel is also called high carbon chrome steel, carbon content Wc about %, Wcr for chromium content. Bearings and shaft is too loose, The smaller the diameter of the shaft or set set not tighten) ； Rotates, the bearing clearance is too small, too tight, Set set of tighten too far) ； 。 In addition, in the gearbox design, planet carrier support bearing end bearing size is too small, to avoid as far as possible in the actual application analysis we found that even if meet the conditions of life, this kind of design can also lead to small bearing linear velocity is very low, more can't form the oil film. Connected to the building of various rooms such as evaporator, the evaporator in the sinusoidal tube heat exchange with the air, again through the blast air conditioning blowing air of the room. The vibration of the bearing & amp; emsp; & emsp; Bearing vibration is sensitive to bearing damage, such as peeling, indentation, rust, crack and wear will be reflected in the bearing vibration measurement, therefore, through the use of special bearing vibration tester ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency infer the abnormal situation. Threaded parts do ahead of time to protect, prevent the SDH material binding thread; Hall, after testing, if the motor is no problem, we can directly loading, in accordance with the SDH: harmonic proportion to material mixed uniformly; , invigorating the oil hole and oil discharge hole of the motor end cover when oil change must be clean, maintain channel unobstructed. Prevention measures: strictly to filter oil, sometimes, because of some foreign material mixed with contact surfaces between, also can cause serious wear and tear, and will cause serious scratches on the surface of the wear called abrasive wear. Solution: to replace bearing, lubricating oil contains some figure stern tube metal chips to run according to the crew's description of the above, can preliminary judgment stern bearing have been part of the burning fuse.
