Cylindrical roller bearings lead to early wear and tear of many reasons, summed up in the following five aspects.
① unreasonable structure design including design calculation error; structural design, size, accuracy improper; TIMEKN bearing alloy materials, coating materials, and bearing the backing material, improper lubricant selection.
② the production process defects, processing quality is not high TIMEKN include sintered bearing alloy casting, rolling flawed double sheet metal plating and coating complex process, machining process backward, leading to cylindrical roller bearings alloy microstructure organization, composition, performance, and dimensional accuracy does not meet the design requirements.
③ poor assembly process including assembly process backward, uncivilized production management, not strict; the assembly does not meet the accuracy requirements of the original design after assembly. Diesel engine factory unscientific, inappropriate adjustments, and will lead to early damage to the bush.
④ use and poor maintenance practices include inadequate, lax maintenance system operator user negligence, excessive overloading, speeding and other man-made or accidental harsh working conditions and the environment.
⑤ implicated by the failure of other components of the lubricating oil, filter inappropriate choice or failure, or journal bearing excessive deformation, damage, vibration will cause TIMEKN corresponding bearing damage.
Cylindrical roller bearings enjoying: For as long as possible in order to maintain the good condition of the original cylindrical roller bearing performance shall take care of themselves, overhaul, in order to prevent accidents in already, to ensure reliable operation of the progressive consumption, economy.
Enjoying the best job specification corresponding machine operating condition, periodically stop. Including monitoring the operation state, the complement or substitute smoothing agents regularly demolition inspection. Operation maintenance matters, there is a cylindrical roll rotating sound, vibration, temperature, state of the roller bearing smoothing agents and the like.
Bearing maintenance: TIMEKN bearing cleaning: Removing the lower bearing overhaul, the first recorded appearance of cylindrical roller bearings, to confirm the remaining amount of smoothing agents, followed by sampling inspection of smoothing agents, wash bearings. As a cleaning agent, use ordinary gasoline, kerosene.
Removed to the cylindrical roller bearings cleaning, cleaning and fine cleaning sub-thick, were placed in the container, put the first metal net bottom, bearing no direct contact with the dirt container. Coarse cleaning, if the dirt with a rotating bearing, cylindrical roller bearings will damage the rolling surface and should be attention. In the crude oil washing, use a brush to smooth and eliminate grease, adhesive material, generally clean, into sperm washing.
Sperm washing is bearing while rotating in cleaning oil, while careful cleaning. In addition, cleaning the oil have always adhere to clean.
Bearing maintenance and discrimination: In order to determine the disassembled cylindrical roller bearings can be able to use to wash the clean bearing in SUNTHAI after inspection. Check the raceway, rolling surface, with the surface state, insist shelf wear condition, increasing the bearing clearance and dimensional accuracy has nothing to fall damage, abnormal. Non-leave type of small ball bearings, the inner ring with one hand to support the degree of rotation of the outer ring to confirm whether fluently.
