When the locomotive is running on the line; once the bearing is out of order; it will cause the entire train to be inoperable; especially the passenger train will have a serious impact; the negative impact will be greater; therefore, the prevention and reduction of the locomotive bearing problems; the safe transportation of the locomotive appears It is very important to be able to detect the bearing with danger before the bearing is loaded; ensuring the qualified bearing fittings on the car is the main point of this paper. The severe damage of the bearing is often not caused by a single cause; Analyze the cause of bearing problems.
First, the bearing's abnormal wear bearing is used for too long; beyond the service life of the bearing, it simply forms the fatigue of the raw material; coupled with the fierce impact effect, the raw material is deformed; the roller and raceway surface are peeled off and the piece is rolled; Then the formation of smoothness and increased oscillation.
It is very important to protect the oil supply of the locomotive bearing; in particular, the excessive oil supply to the bearing can ensure the bearing has an outstanding smoothing effect; the lack of oil and excessive oiling are also very simple to form a bearing problem; the oil is added less and the bearing is simply formed poorly. Fever; more additions are also simple to form mixing and overheating; once the oil and other impurities and water fall into the oil; it will affect the normal clearance and establish the necessary oil film.
When the bearing is used for a period of time; the inner ring of the bearing, the rolling element, the cage, the outer ring, the raceway, etc. must have certain defects and scars; the smoothness of the bearing is formed; the heat of the bearing is incurred; the heat for a long time;
.1) Accelerate the fatigue of raw materials; reduce hardness.
.2) Dilution of bearing smooth oil.
Second, the impact of the device on the bearing bearing inner ring and the shaft cooperation gap interference does not match; it is also very simple to form bearing problems; large interference; very simple formation of the bearing inner ring due to excessive tensile stress and crack; interference Over. From the heart of Fiji.
When assembling the bearing, do not follow the process requirements; use the copper hammer to impact the bearing; form the deformation of the cage; the traction motor bearing inner and outer ring device is incorrect or other reasons cause the axial traverse amount to disappear; forming the bearing shaft is squeezed.
Bearing assembly cooperation gap cooperation is not appropriate; also simple to form bearing problems; small clearance is very simple to form roller and raceway conflict heat; followed by rising temperature; bearing inner ring, roll body, cage, outer ring, end cover The temperature is not the same; therefore, the amount of expansion is also slightly different; it also forms a further reduction of the cooperative gap; the heat of the bearing is added.
