During bearing installation, mechanical, heating or hydraulic methods can be selected according to its type and size. However, under Fag Tapered Roller Bearing no circumstances can the tapered roller bearing ring, cage, rolling element or seal be directly knocked.
The force exerted on fag bearing during installation must not be Fag Tapered Roller Bearing transmitted from one bearing ring to another through the rolling element, otherwise the raceway may be damaged.
First of all, there are two oil tank equipment, one for use and one for standby. They are switched regularly. The standby oil tank is cleaned, the oil is heated and precipitated, and the purified oil is separated from water.
2、 A degassing plate in the oil return area shall be set in the oil tank to reduce the impact of refueling; Magnetic grid device – adsorption of iron mechanical Fag Tapered Roller Bearing impurities in oil return area;
Floating oil suction port – oil suction at an appropriate position below the liquid level; Automatic drainage device or flooding alarm device – discharge the precipitated and separated water in time; Dynamic liquid level control – alarm or interlock for sudden large amount of oil leakage.
3、 The filtering accuracy of oil Fag Tapered Roller Bearing supply is high. Generally, the filtering accuracy is required to reach 10 ~ 20 μ M to ensure the cleanliness of oil products.
4、 The oil supply pressure shall be kept constant, and the working pressure control device of the lubrication system shall have high sensitivity and accuracy to avoid working pressure drop due to pressure change, resulting in insufficient oil supply of local lubrication system and wear and sintering of oil film fag bearing.
5、 The volume of the oil tank shall be 35 ~ 40 times of the displacement per minute of the oil pump, and some shall be even Fag Tapered Roller Bearing larger. Under the condition of high oil level operation, ensure that the oil stays in the oil tank for a long enough time.
6、 The pressure tank in the lubrication system must operate normally, control the reasonable oil filling flow value and liquid level in the tank, and play a part in buffering the pressure fluctuation of the system and the supply of emergency oil source.
7、 The oil supply temperature shall be controlled between 40 ± 2 ℃ to ensure the viscosity of the oil Fag Tapered Roller Bearing supply.
8、 The filter must exhaust the residual air in the filter cylinder before switching the tapered roller bearing.
For clearance fit tapered roller bearing rings, it is recommended to apply a thin layer of anti creep corrosion agent on the mating Fag Tapered Roller Bearing surface to prevent friction corrosion between the mating surfaces.
Correct installation is very Fag Tapered Roller Bearing important for the use of fag bearings. I hope you can use the correct installation method in the future.
Raceway sound of bearing and its control method raceway sound is a smooth and continuous sound generated by the rolling body rolling on the raceway surface when the Fag Tapered Roller Bearing shaft is running. It is a unique basic sound that will occur in all fag bearings.
The general sound of one-way bearing is the sound of raceway plus other sounds. The greater the rigidity of the bearing pedestal, the lower the sound pressure level of the raceway sound.
If the radial clearance is too small, the sound pressure level and dominant frequency of raceway sound will increase sharply with the decrease of radial clearance.
Fatigue failure of one-way bearing is a surface form of failure, which is mainly manifested in the initiation, propagation and fracture process of fatigue crack, and the long-term impact of load failure under alternation. Cracks are in two ways:
1. On the surface, this is the external load caused by the plastic deformation of the working surface and the periodic change of the contact stress of the strain hardened surface during the rolling contact process of fag bearing,
and finally the formation of the surface crack between the two from the developing inner surface, due to the lubricant and the open force of the working surface, Crack down on the wall and force the crack to move forward;
2. From the surface layer, under repeated pressure, the contact of the surface will initially produce cracks at a certain depth at the place where the surface is exposed, and from the angle along the surface direction to a certain depth,
from behind the surface of the contact surface, and beyond the surface, and finally form corrosion stripping, leaving a horse pit.
From the surface of one-way bearing, or from the cracks in the surface layer, these two objectives (carburization, quenching and other surface heat treatment of parts. If there is uneven hardness, organization, and non-uniform internal stress and other disadvantages,
the contact stress is generally affected by the opposite underground cracks. If the surface quality of parts is poor, there is a defect (oxidation, decarburization), Poor friction or lubrication, cracks from the surface.
The methods to control the sound of raceway are: select low-noise fag bearings, that is, bearings with small waviness, and carefully select the service conditions. Raceway noise often affects the noise of the whole machinery. Reducing raceway noise can reduce the noise of the whole machinery.
Rolling sound of one-way bearing and its control method rolling sound is the harsh metal friction sound that can occur in cylindrical roller bearings on all occasions. Most of it occurs in larger types of grease lubricated bearings,
which is more likely to occur in greases with degraded base oil performance, and almost does not occur in oil lubrication. In addition, it is easy to occur in winter. When bearing pure radial load, it is easy to occur in the case of large radial clearance, and it is easy to occur in a specific speed range with different models and sizes,
both continuously and intermittently. Special processing methods for the outer ring raceway can prevent the occurrence of rolling sound. If necessary, this kind of bearing can be selected,
or the radial clearance of fag bearing can be appropriately reduced, the lubricating grease with excellent performance can be used and the rigidity of parts matched with the bearing can be improved
