In cylindrical roller bearing early wear for many reasons, summed up in the following five aspects.
The unreasonable design of the structure including error calculation; structure design, size, accuracy of improper; EDAbearing bearing alloy materials, coating materials and bearing a backing material, improper selection of lubricating oil.
The production technology, processing quality defects in rolling is not high including EDAbearing bearing alloy casting, sintering, double sheet metal and plating plating process defects, the machining process backward, cause the microstructure, material bearing alloy cylindrical roller composition, properties and dimensional accuracy does not meet the design requirements.
The assembly process of bad including assembly backward technology, production management, no civilization is not strict; does not meet the assembly after the assembly precision requirements of the original design. Diesel engine before leaving the factory is not scientific, not appropriate, will lead to the early damage of bearing.
The use and poor maintenance includes specification is not perfect, maintenance system is not strict, manipulation of dereliction of duty, excessive overload, overspeed, or unexpected conditions and environment etc..
Failure of lubricating oil and implicated by other parts, filter selection or failure, the bearing or shaft neck excessive deformation, damage, vibration will cause the corresponding EDAbearing bearing damage.
Cylindrical roller bearing maintenance: for long time to maintain the performance of the original cylindrical roller bearings in good condition as far as possible, to maintenance, repair, in order to prevent accidents in already, ensure the operation of solid, consumption, economic progress.
Job specification are the best operating conditions of the corresponding mechanical, a regular stop. The content includes monitoring running state, add or change the smooth agent, periodic disassembly inspection. Maintenance of operational matters, a rotating cylindrical roller bearing sound, vibration, temperature, smooth agent status etc..
Maintenance of the bearing: EDAbearing bearing cleaning: remove bearing overhaul, the first recorded appearance of cylindrical roller bearing, confirm that the residual smoothing agent, after sampling checks with a smoothing agent, wash bearings. As a cleaning agent, general use gasoline, kerosene.
Remove cylindrical roller bearing cleaning, cleaning rough and fine cleaning, placed in a container, metal mesh on the bottom first, make the bearing does not directly contact the container dirt. Rough cleaning, if you rotate the bearings with dirt, can damage the cylindrical roller bearing rolling surface, should be noticed. In the crude oil washing, use brush put to grease, adhesive material, generally clean, to wash.
Sperm washing, cleaning of oil bearing is in while rotating, while carefully cleaning. In addition, cleaning the oil should always keep clean.
Maintenance of the bearing and discrimination: discrimination for cylindrical roller bearings can be removed to use, to check in the EDAbearing bearings washed clean after. Check the raceway surface, rolling surface, with the increase of the state, cage wear, bearing clearance and the irrelevant dimension precision landing of injury, abnormal. Non separation of small ball bearings, inner ring with one hand supporting degree, rotate the outer ring to confirm whether fluently.
