In order to give full play to INA Bearing and maintain its due performance for a long time, regular maintenance (regular inspection) must be done. Through proper regular inspection, it is very important to find faults early and prevent accidents before they happen, which is very important to improve productivity and economy.
Key factors affecting the service life of roller bearings for many rotating Ina Roller Bearing machinery products, their service life mostly depends on the service life of key parts of the product. “Maintenance free” bearings are not one-way bearings that will never be damaged or fail,
but that will not be damaged within a certain period of time. Here, the Ina Roller Bearing designers calculated the service life of the bearing ina. The service life of the bearing is greater than or equal to the overhaul cycle of the mechanical product.
In this way, the bearing can be “maintenance free”. When the mechanical product is overhauled, it can be replaced with a new bearing without maintaining the used bearing.
When the ina bearing is disassembled for inspection, the appearance record shall be made by photography and other methods. In addition, confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearing.
a. The cleaning of bearings is divided into rough cleaning and fine cleaning, and a metal grid can be Ina Roller Bearing placed at the bottom of the container.
b. During rough cleaning, use a Ina Roller Bearing brush to remove grease or adhesion in the oil. At this time, if the bearing is rotated in oil, pay attention to the damage to the rolling surface due to foreign matters.
The commonly used cleaning agent is neutral water-free diesel oil or Ina Roller Bearing kerosene, and sometimes warm lye is used as needed. No matter what kind of cleaning agent you use, always filter it and keep it clean.
After cleaning, apply antirust oil or antirust grease on the roller bearing immediately.
2. Inspection and judgment
In order to judge whether the Ina Roller Bearing removed bearing can be reused, it is necessary to check its dimensional accuracy, rotation accuracy, internal clearance, mating surface, raceway surface, cage and sealing ring.
The inspection results can be judged by those who use inertial bearings or are proficient in bearings.
The judgment criteria vary according to mechanical properties, importance and inspection cycle. In case of the following damage, the Ina Roller Bearing roller bearing shall not be reused and must be replaced.
1) Fracture and defect of bearing parts.
2) Stripping of the rolling surface of the raceway surface.
During the operation of the mechanism, the part where the one-way bearing is installed is allowed to have a certain temperature. When touching the mechanism shell by hand, it should be normal to feel that it is not hot. Otherwise, it indicates that the temperature of ina bearing is too high.
The reasons for high bearing temperature include: the quality of lubricating oil does not meet the requirements or deteriorates, and Ina Roller Bearing the viscosity of lubricating oil is too high;
The mechanism assembly is too tight (insufficient clearance); Roller bearing assembly is too tight; The bearing race rotates on the shaft or in the shell; Excessive load; Broken bearing cage or rolling element, etc.
The vibration system composed of stiffness, flexibility, mass and damping determined by the structural design parameters of one-way bearing will produce vibration suitable for its mechanics under operating conditions.
Vibration caused by deviation in manufacturing and processing. The smaller the deviation is, the smaller the vibration is.
The roundness, waviness and surface roughness of the steel ball surface are the factors that have a great impact on the vibration of INA Bearing parts, followed by the shape error and surface roughness of the inner ring and outer ring channels, and then the cleanliness and lubricant quality of roller bearing.
Operating conditions, such as installation conditions, rotating speed, axial load direction, quantity, etc.
