TIMKEN Bearing Troubleshooting Method

    Each type of TIMKEN bearing design exists in a common removal process. Regarding the smaller bearings, there is a time that the driver can assist in the removal of the bearings. If the operation is not done properly, it can protect the bearing, shaft or shell, requiring noble training. As a result, heavy and light industrial bearings dedicated a small amount of profit injection. When a new or reformed bearing is absorbed, it is not packaged until the preparation device is in use. This is especially used in light industry, where the task environment is often stubborn, the load is heavy, and dirt and purification are rare areas.

 

    Heat lamps or other heating facilities can be used. Even wet or unprotected hands or large numbers of chemical gloves kept in contact can cause seal carving in a small sea area, which can cause bearing fatigue. Regarding the installation of close cooperation, or press, or has been locked in the center of the first degree shaft, there is no machine to remove the bearing puller, the inner ring of the bearing can be heated to aggravate the relocation. If the torch is once, it will change the function of the bearing steel and the bearing must be abandoned.

 

    The service life of any TIMKEN bearing is largely derived from its absorption for protection and maintenance. TIMKEN bearing storage has special anti-erosion coating bearings to choose from, but most of the bearings do not have anti-erosion materials. Bearing performance can incur noble downtime, facility protection and faults. This includes bearing storage, cleaning, cleaning, testing and installation. The idea of anti-conflict bearing applied to all.

 

    Bearings here are not subject to high humidity or sudden and violent measurement changes that can cause condensation in the sea. There is no tube bearing type, and the bearing must be particularly carelessly removed. There is no need to store indirectly on the lime ground, where condensed water can be collected and bearing.

    

    In order to achieve the functions of high facilities and operate reliably with minimum protection profits, accurate solutions must be followed. Bearings that are being resolved and stored must be taken carelessly to ensure that they will not rust or corrode.

 

    Assemble and reform TIMKEN bearings are shipped with a protective insulating layer, which are generally covered with paper or other packaging at one time, and are shipped in a suitcase or wooden box at one time. Always put bamboo paper or Xu, if not, in the roller and tapered roller bearing cup competition plastic sheet. The tea tray or the bearing TIMKEN bearing on the store shelf is the main component of the once secondary light industry facility.

 

    TIMKEN bearing rear axle drives an important part of wheel movement. The main compound in the work of TIMKEN bearings can withstand bending and torque while absorbing some impact loads. The overall carbon alloy hardened steel of the axle is hardened after induction heating, which is commonly used in quenching. The depth of the hardened layer is 4-6mm, and the hardness is 50~55HRC. The production of TIMKEN bearings found that TIMKEN bearings often burn out, which seriously affected the quality of induction hardening of TIMKEN bearings and parts produced. The test shows that the burned area of TIMKEN bearing is located in coil 225. In the vicinity of the construction site, expand the regularity of the fault characteristics on both sides.

    The axle sensor heating, in addition to heating the workpiece, is the main heat loss of the heat generated by the sensor in the three ways.

 

    (1) Heat radiates to the surroundings. The guiding magnet, the induction coil are placed on insulating paint and glass fiber cloth. This form of heat loss is small, the heating is even, and it has little effect on sensor burnout.

    (2) The heat of cooling water. This part of the heat dissipation cools the sensor, enabling the safe operation of induction heating. The study found that the intake of water at 0-180 degrees, low water temperature, indicating a good heat exchange cooling water, smooth water, no water temperature; more than 180. Because of the length of the flow path, the increase in water temperature and the increase in water temperature change the heat exchange, because the sensor can easily cause the temperature of a site (such as 225. About part) to rise, which is the main induction coil burning.

    (3) The heat transfer plate of the induction coil, the current density of part of the plate, the large cross section and the low water temperature, the area of ​​the heat transfer plate of the coil. The part of 0 to 90 degrees and 270 -360 degrees is far away from the nearby induction coil plate, which has good thermal conductivity; away from the plate, the thermal conductivity is poor. 90 to 270 pieces of induction coils make the larger induction coil temperature in this area easy to appear in this part Appears like burned coils. The heat flow of the induction coil is compared in different parts. The thermal induction loop in the area near 225 degrees, and has carried out the savings, so the area is prone to large differences between the induction coil burning phenomenon.
