Basic Installation Conditions And Daily Maintenance Points Of Ina Rolling Bearing

Ina Rolling Bearing

If foreign matters such as iron filings, burrs and dust enter the INA Bearing, the rolling bearing will produce noise and vibration during operation, and even damage the raceway and rolling element. Therefore, before installing the bearing, you must ensure that the installation surface and Ina Rolling Bearing installation environment are clean.

Lubrication has a very important impact on the operation and service life of ina bearings. Here we briefly introduce the general principles of selecting grease. Ina Rolling Bearing Lubricating grease is made of base oil, thickener and additives. The performance of different types and different brands of lubricating grease of the same type varies greatly, and the allowable rotation limit is different.

Pay attention to it when selecting. The performance of grease is mainly determined by the base oil. Ina Rolling Bearing Generally, the base oil with low viscosity is suitable for low temperature and high speed, and the base oil with high viscosity is suitable for high temperature and high load. The water resistance of thickener determines the water resistance of grease. In principle, greases of different brands cannot be mixed,

and even greases with the same thickener will have bad effects on each other due to different additives.

1) The installation space of rolling bearing can be accommodated in the bearing installation space. Because the rigidity and strength of the shaft are paid attention to in the design of shaft system, the shaft diameter, i.e. ina bearing inner diameter, is generally determined first. Ina Rolling Bearing However, there are many size series and types of rolling bearings, and the appropriate bearing type should be selected from them.

Basic Installation Conditions And Daily Maintenance Points Of Ina Rolling Bearing

2) Load the size, direction and nature of bearing load [the load capacity of the bearing is expressed by the basic rated load, and its value is contained in the bearing size table] the load of the rolling bearing is rich in changes, such as the size of the load, whether there is only radial load, whether the axial load is unidirectional or bidirectional, the degree of vibration or impact, etc. After considering these factors, choose the appropriate bearing type.

3) Bearing type whose speed can adapt to the mechanical speed [the limit value benchmark of bearing speed is expressed by the limit speed, and its value is contained in the bearing size table] Ina Rolling Bearing the limit speed of ina bearing is not only taken from the bearing type, but also limited to the bearing size, cage type, accuracy grade, load conditions and lubrication mode. Therefore, these factors must be considered in the selection.

4) The rotation accuracy is the type of bearing with the required rotation accuracy [the dimensional accuracy and rotation accuracy of the bearing have been standardized by Ina Rolling Bearing GB according to the bearing type] the machine tool spindle, gas turbine and control machine require high rotation accuracy, high speed and low friction respectively. At this time, rolling bearings with accuracy above level 5 should be used.

5) The bearing type whose rigidity can meet the rigidity required by the mechanical shaft system [when the bearing bears load, the contact part between the rolling element and the raceway will produce elastic deformation. “High rigidity” means that the deformation of this elastic deformation is small] Ina Rolling Bearing in the machine tool spindle and automobile final reducer, the rigidity of the bearing must be improved while improving the rigidity of the shaft.

The deformation of rolling bearing under load is smaller than that of ball bearing. Applying preload (negative clearance) to ina bearings can improve rigidity. Ina Rolling Bearing This method is suitable for angular contact ball bearings and tapered roller bearings.

6) Analysis of relative inclination of inner ring and outer ring factors causing relative inclination of bearing inner ring and outer ring (such as shaft deflection caused by load, poor accuracy of shaft and housing or installation error), and select ina bearing type that can adapt to this service condition. If the relative inclination between the inner ring and the outer ring is too large, the bearing will be damaged due to internal load. Therefore, the type of bearing that can withstand this inclination should be selected.

7) The installation and disassembly frequency and methods of regular inspection of installation and disassembly. When the installation and disassembly are frequent, it is more convenient to use Ina Rolling Bearing cylindrical roller bearing, needle roller bearing and tapered roller bearing with separable inner ring and outer ring.

Tapered hole self-aligning ball bearings and tapered hole self-aligning roller bearings can be easily assembled and disassembled by using fasteners or withdrawal sleeves.

The surface of rolling bearing is coated with antirust oil. You must carefully clean it with clean gasoline or kerosene, and then apply clean high-quality or high-speed and high-temperature lubricating grease before installation and use. Cleanliness has a great impact on ina bearing life and vibration noise. However, we would like to remind you that the fully enclosed bearing does not need cleaning and refueling.
