Type Of Iko Bearing Used For Radiator

Type of Iko Bearing

In the bearing machinery industry, there are many type of Iko bearing

But there are few type of IKO bearing used on radiators: sleeve bearings, ball bearings, magnetic bearings, water wave bearings, magnetic core bearings, etc. Among them, magnetic bearing, water wave bearing, magnetic core bearing and Laifu bearing are also improved from the above two sleeve bearings and rolling bearings, and the working principle has not changed. At present, IKO bearings mainly used in ordinary air-cooled radiators include oil bearing and ball bearing.

Oil containing type of IKO bearing is a sleeve bearing with sliding friction.

Lubricating oil is used as lubricant and drag reducer. At the beginning of use, the working noise is low and the manufacturing cost is low. However, type of IKO bearing is seriously worn and its service life is much lower than that of ball bearing. Moreover, the IKO bearing has been used for a long time.

Due to the oil seal, the lubricating oil will gradually volatilize, and the dust will enter the type of  IKO bearing, which will cause problems such as reduced fan speed and increased noise. In serious cases, the fan eccentricity caused by IKO bearing wear will cause severe vibration. Affect the service life of the bearing.

The ball bearing changes the friction mode of type of Iko bearing

and adopts the rolling friction method. This method more effectively reduces the friction resistance of IKO bearing, effectively improves the service life of fan bearing, and therefore prolongs the service life of radiator. The disadvantage is that the manufacturing process is more complex, resulting in higher costs. These are probably the types of IKO bearing often used by radiators. When using them, we must choose suitable bearings, do a good job in maintenance, prolong service life and reduce production costs.

Several Characteristics And Characteristics Of Timken Bearing Are Analyzed

Several Characteristics And Characteristics Of Timken Bearing Are Analyzed

1. Types and characteristics of sliding Timken bearings

I type of sliding Timken bearing Or called radial sliding Timken bearing, 1. Sliding Timken bearing is divided into centripetal sliding Timken bearing according to the accepted load. Mainly accept radial load; Thrust sliding Timken bearing mainly accepts axial load.

2. Sliding Timken bearing is suitable for places with low speed, high precision, heavy load and structural requirements.

Compared with sliding Timken bearings, rolling Timken type of iko bearing are rolling friction. Its contact surface is small (ball Timken bearing is point contact and roller Timken bearing is line contact), with low friction coefficient, less heating, less wear and good precision persistence. It is suitable for operation at higher speed, but its bearing capacity is slightly poor and its vibration resistance is poor.

3. Centripetal sliding Timken imported bearing

There are two types of centripetal sliding Timken type of iko bearing: integral type and split type.

Angular contact ball bearing,

namely radial thrust ball type of iko bearing, can be loaded with more steel balls, its radial bearing capacity is greater than that of ordinary ball bearing, and can also bear large axial load or pure axial load at the same time. Its allowable working speed is similar to that of deep groove ball bearing and its support rigidity is stronger, but it requires accurate installation and is very sensitive to axis misalignment error,

Generally, it does not need to bear the radial load alone, but it must bring additional axial load while bearing the radial load. This kind of type of iko bearing has many variants and is widely used. It is often made into three series with 15 °, 25 ° and 40 ° contact angles. The larger the contact angle is, the higher its axial load capacity is. However, it is appropriate to use a small contact angle at high speed.

Most of these bearings are used in pairs for small-span rigid double support shafts or precision spindles. When in use, the clearance should be carefully adjusted. By changing the axial distance between the inner and outer rings of the type of iko bearing, the internal clearance of the bearing can be adjusted.

At the same time,

several sets of type of iko bearing can be installed in parallel and given a certain pre interference, which can improve the rigidity of the bearing system.

A single bearing of this type of iko bearing can only bear the axial load in one direction. At the same time, other bearings need to be configured to offset their additional axial forces. When installed in pairs, their additional axial forces offset each other, and they can bear the axial load of two forces upward, and have strong axial limit capacity in two directions,

Generally, two sets of bearings are installed in pairs, with their outer ring wide end face opposite (back-to-back) or narrow end face opposite (face-to-face), in which the rigidity of the back-to-back installation bearing system. In order to facilitate installation in pairs or groups, some bearing factories supply bearings in pairs, three sets in groups and four sets in groups.

In this way,

the processing consistency of the supplied type of iko bearings in the same batch is good, the load is borne more evenly during use, and the additional axial forces offset each other more thoroughly.

This type of iko bearing can be divided into two types: separated type and non separable type. The separated type bearing is used when the installation conditions are limited and the outer ring or inner ring is required to be removed from the whole set of bearings for separate installation.

Because the separated type angular contact ball bearing is widely used in magneto, it is also called magneto bearing. In this type of bearing, the locking port is on the inner ring, which can be adapted to higher speed.
