Bucket Turbine Bearings

1.The common faults of bucket turbine bearings and their treatment measures are as follows:

1.There are noises and vibrations in the gear meshing, it should be stopped for maintenance, and the meshing state of the gears should be checked. You can use coloring powder to check the contact area of the tooth surface to confirm whether the meshing is normal.

2.If there is a sound inside the slewing bearing, you must add grease to multiple points and rotate in forward and reverse directions until the sound is reduced or disappeared.

3.The bucket turbine bearing eccentric load is serious, which can be corrected by adjusting the arm length and stowage of the bucket turbine.

4.The bucket turbine bearing has inner and outer ring clearance, and the rolling element of the large bucket turbine bearing is replaced by a professional maintenance team. The specification is 100*98.5mm.

5.Replace the sealing strip, the specification is 5*21mm

6.As the bucket turbine bearing for the power plant bucket turbine, the steel mill bucket turbine stacker and reclaimer slewing bearing, confirm the drawings and spare a set of large bucket turbine bearings for emergency needs

7.Common models of bucket wheel machines, 1797/2500G, 1797/2600; 1797/2635 and 1797/3230 series.

2.The acceptance inspection,maintenance and installation standards of bucket turbine bearings are mainly based on the following:

1. The acceptance data is subject to the drawing confirmation drawing.

2. The core data of detection include clearance, tooth jump and slewing bucket turbine bearing performance

3. The three main aspects of maintenance are tooth surface inspection, raceway inspection and rolling body inspection

4. The reference requirements for installing bucket wheel bucket turbine bearings are based on the installation technical requirements of the bucket turbine bearing, mainly for the installation base surface, bolt connection and rotating gear jump.

5. After the installation, replacement, maintenance and repair of the bucket wheel bucket turbine bearing, there is no abnormal noise, no vibration, no dead point, and no force settlement after the overhaul.

When replacing the large bucket turbine bearing bearing of the ladle and the bucket turbine bearing of the bucket wheel machine stacker and reclaimer, there is usually a problem of installation accuracy error.

For example, there is a situation where the mounting base is equipped with a drill, the fitting clearance of the mounting hole of the large bearing is too small, and the mounting base is deformed. displacement situation.

How to solve the problem of uneven installation of large bucket turbine bearings in a short time? The following are simple, practical and effective solutions.

1. Replace the next level mounting bolt specification. If M42 was originally used, M36 can be used for emergency, and M33 can be used instead of M36. The grade is not lower than 8.8 high-strength bolts.

2. Adjust the rotation direction of the bucket turbine bearing. Generally, if the deviation is not large, the bolts can be installed normally.

3. The aperture of individual mounting bases can be solved by reaming at a constant speed.

4. In extreme cases, the bucket turbine bearing should be reamed. Boring and milling machines can be used to expand the hole, and the mounting hole is generally expanded into an ellipse.

Regarding the design characteristics of the large bearing of the steel mill bucket turbine and the large bearing of the ladle, because of the special working conditions, at the beginning of the design, the large bearing is required to be able to withstand high load, high temperature, dust, safety, reliability and life.

Can exceed the design requirements of ordinary bearings. Technical details of slewing bearing, technical service of slewing bearing Yuan Gaogong, I5B–965B–OI9O.. Communication is efficient.

First of all, the design concept should emphasize heavy-duty bearings, so the inner and outer rings of the bearing should be strong and solid, the rolling elements should be large, the cage should be segmented or integral cage, and the material should be PA66 or steel cage.

Secondly, the choice of lubricating grease can use 2 lithium base grease, lubrication is extremely important. Multiple batches, multiple batches, to ensure lubrication from beginning to end.

Thirdly, lubrication protection, dust cover, and dust baffle can effectively prevent foreign objects from entering.

Finally, the material and hardness can be higher than the design manual, and the design cost is appropriately increased.
