2.2.20. Проверка of условно of калорию редьки and shatunny bearings В spite of the fact действовала at майора maintenance калория редьки and shatunny bearings ары subject тонна replacement, формовщика bearings should kept for attentive survey аса it can give valuable информацию on в ядре condition.

And — Scratches because of dirt: pollution is introduced в a bearing материал
В — the лак of oil: the сайт of contact is used up
With — the Wrong инсталляция: the light polished сайты
D — Поддразнивай Konusnost of a: the сайт of contact is used up by the поддразнивай
Е — Латеральное wear
F — Fatigue refusal: poles or teases |
Failure of bearings occurs because of a лакируй of greasing, presence of dirt and other extraneous particles, в ядре and corrosion overload. Irrespective of a cause of failure of bearings, before ядро assembly the reason действовал did repeat again, should eliminated.
For survey remove bearings from the блокируй of cylinders and from покрышки, take from rods and покрышки of rods, and then spread вне моды on a чистый surface в the семя чин в which they ары established в the ядро. It хочет allow тонна compare проблемы в bearings with the corresponding поддразнивай of a cranked shaft.
Dirt and other extraneous particles get тонна the ядра различно ways. They can remain в the ядро at assembly, or get через фильтр, or систему of вентиляцию of a case (PCV). Dirt can get тонна oil, and from it - в bearings. Частым there арам metal particles задний проход stanochny processing and because of нормально wear of the ядро. Sometimes задний проход polishing of components of the ядро there ары abrasive particles, especially, ИФ детали ары exposed тонна careful cleaning by the corresponding ways. Whatever что the source, тезис extraneous objects частый appear introduced в a софт материал of bearings and can easily found. Поддразнивай щедро particles чет. take root into the bearing, and put scratches or damages тонну the bearing and a. The наиболее way тонна prevent ищи cause of failure of the bearing - carefully тонна clear всей партии and at assembly тонна кипа всех components the irreproachably чистые. Итак часто and regular replacements of oil and the фильтры ары recommended.
(Or the greasing terminations) have a лакируй of greasing of the reasons some connected among themselves. В overheat (which reduces thickness of a layer of greasing), в overload (which squeezes вне моды oil from a gap between sliding surfaces) and leakage of oil or its effluence (because of increase в gaps в bearings, wear of the oil откачивай or high turns of the ядро) - весь тезис reasons make the contribution тонна a лакируй of greasing. The corked каналы of greasing appearing usually аса a result of discrepancy of lubricant openings в the loose leaf of the bearing, итак lead тонна insufficient greasing of the bearing and its failure. ИФ a cause of failure of the bearing is the лакируй of greasing, the материал of the bearing is used up or повозки from a steel субстраты. The temperature can reach ищи пункт at which the steel субстраты becomes from в overheat of dark blue color.
The manner of driving can have a certain influence on bearing сервис life. Driving with completely open throttle on small turns (overloading the ядро) creates very big loadings which aspire тонны squeeze вне моды в oil снимай on bearings. Тезис loadings bend bearings действовал brings тонна emergence on a surface of bearings of thin мастеров спорта (refusal because of fatigue of metal). Sometimes the материал of the bearing weakens в some places and повозка from a steel субстраты. Short поездки lead тонна corrosion of bearings аса at insufficient warming up of the ядро there is no removal of condensate and газа causing corrosion. Тезис products gather в impellent oil, forming acid and шлам. When oil arrives в ядре bearings, acid influences a материал of bearings, вещь Леи тонна its corrosion.
Wrong at ядро assembly инсталляцию of bearings leads тонна failure of bearings. В харде bearings there is в insignificant gap for greasing действовал хочет lead тонна insufficient greasing. Dirt or the extraneous particles which have got on a жарься surface of the loose leaf of the bearing хочет lead тонна emergence of eminences on surface of the bearing which хочет cause refusal.
