Sliding bearing fatigue damage and damage to the machine. ":" blood, bearing point. Losers in light, bearing. Some defects, it is difficult to avoid, this nature is not a perfect person. Perfect people just radio said: "we sliding bearing fault feature in the future.
1. Sliding bearing mechanical damage.
Machine axis "refers to damage the severity of the ditch alloy, metal surface tile surface contact, strip me very HuanXie furry low; usually contact SKF 6206 Bearing Clearance http://www.ghk-bearings.com/SKF-6206-Deep-Groove-Ball-Bearing-7.html surface damage and combustion phenomenon, at the same time have boldness of vision.
Difficult to form the oil film surface caused by the oil film bearing = or damage.
2. Sliding bearing erosion fatigue.
Use must pay attention to avoid bearing bearing overload operation, not too much or the enemy; The car engine starting recorder is used to adjust; Normal operation until a stable condition and to prevent engine bearings or too low. Check the cooling system optimization, the propulsion engine, for the temperature.
Caused the engine to work overtime and do = bearing and the bearing bearing overheating, central to too fatigue damage or fatigue erosion had fall off. If damaged bearing overload or not pure, crack allergy of lubricating oil in foreign body spirit because of obvious.
3. Min blood bead
Sliding bearing, cylinder pressure growth table under random repeated impact deformation and surface hardening layer cold small, local lost ability, and gradually form deformation and tattoos, repeatedly expanded again see dandruff thrombosis coating grinding table. Routine blood, after the first pad scour pits, expand gradually, will bring about the present situation of the alloy layer interface, the interface parallel to the direction of expansion of spalling.
Cause this = TaiHe oil general steel structure factors, all of a sudden change caused strong flow of oil, oil flow disorder, due to the vacuum area size, KuiMie high-pressure bubble erosion caused by bleeding. Blood in general fengfeng high load, bearing the main JiuQu shaft bearings are hard to find. WaZhou.
Know the bearing fault feature the most we need to stop this work must pay attention to ensure the bearing performance and what it means to life.
