Skills of disassembling fag bearing of vibrating screen

Improper disassembly of the shale shaker fag bearing may cause internal damage to the fag bearing. Contaminants may enter fag bearings or errors may occur during reinstallation. Therefore, you must be very careful when disassembling the fag bearing of the shale shaker, and the shaft center must be properly supported, otherwise the disassembly force may damage the fag bearing of vibrating screen.

Peripheral disassembly fag bearing of vibrating screen

Remove the outer ring of the interference fit. Set several outer ring extrusion screws on the circumference of the shell in advance, tighten the screws equally while removing fag bearing of vibrating screen. These screw holes are usually covered with blind plugs, separable fag bearings of shale shaker tapered roller fag bearings, etc., set several notches on the shoulder of the shell, use cushion blocks, disassemble with a press, or gently knock to disassemble.

Disassembly of fag bearing of vibrating screen with cylindrical hole
  • The inner ring can be easily removed by pressure machinery. At this time, pay attention to let the inner ring bear its pulling force.
  • The inner ring of fag bearing of vibrating screen is disassembled by oil pressure method. Oil pressure is applied through the oil hole on the shaft to make it easy to pull. The wide fag bearing is disassembled by the combination of oil pressure method and drawing fixture.

  • Induction heating method can be used to disassemble the inner ring of fag bearing of Nu and NJ cylindrical roller vibrating screen. It is a method of drawing after heating the part in a short time to expand the inner ring.

Disassembly of tapered fag bearing of vibrating screen

Disassemble the relatively small fag bearing with tight set sleeve, support the inner ring with the stop block fastened on the shaft, turn the nut back several times, and then use the cushion block to knock it down with a hammer.fag bearing of vibrating screen

Structure and performance characteristics of fag bearing

Thrust angular contact ball bearing in fag bearing

The contact angle of thrust angular contact ball bearing is generally 60 °. The commonly used thrust angular contact ball bearing is generally a two-way thrust angular contact ball bearing, which is mainly used for the spindle of precision machine tools. It is generally used together with double row cylindrical roller bearings, and can bear two-way axial load. It has the advantages of high precision, good rigidity, low temperature rise, high speed, convenient assembly and disassembly, etc.

FAG-Deep groove ball bearing
  • Structurally, each ring of deep groove ball bearings has a continuous groove raceway with a cross-section of about one-third of the circumference of the equatorial circle of the ball. Deep groove ball bearings are mainly used to bear radial loads, but also can bear certain axial loads fag bearing of vibrating screen.
  • When the radial clearance of the bearing increases, it has the property of angular contact ball bearing and can bear the axial load alternating in two directions. Compared with other types of bearings with the same size fag bearing of vibrating screen, this type of bearing has small friction coefficient, high limit speed and high precision. It is the preferred bearing type for users to select. Deep groove ball bearing has simple structure and convenient use fag bearing of vibrating screen. It is a kind of fag bearing with large production volume and wide application range.

Structure and performance characteristics of fag bearing

Thrust tapered roller bearings in fag bearings

Because the rolling element in the thrust tapered roller bearing is a tapered roller, the rolling bus and the raceway bus of the washer meet at a point on the axis line of the bearing in structure, so the rolling surface can form pure rolling, and the limit speed is higher than the thrust cylindrical roller bearing. Features: thrust tapered roller bearing can bear one-way axial load. The type code of thrust tapered roller bearing is 90000.

Structure and performance characteristics of double row tapered roller bearings in fag bearings
  • There are many structures of double row tapered roller bearings, a large number of which are 35000 type. There is a double raceway outer ring and two inner rings. There is a spacer between the two inner rings. The clearance can be adjusted by changing the thickness of the spacer. This kind of bearing can bear both radial load and bidirectional axial load, which can limit the axial displacement of the shaft and housing within the range of axial clearance of the fag bearing of vibrating screen. Structural characteristics of tapered roller bearings.
  • The type code of tapered roller bearing is 30000, and the tapered roller bearing is a separate fag bearing of vibrating screen. Tapered roller bearings are mainly used to bear the combined radial and axial loads dominated by radial loads fag bearing of vibrating screen. Compared with angular contact ball bearings, the bearing capacity is large and the limit speed is low. Tapered roller bearing can bear axial load in one direction and limit axial displacement of shaft or housing in one direction.

Treatment of fag bearing temperature rise

  • Check whether the cooling water pressure, water flow and pipeline system are normal. If the water pressure is low, the filter may be blocked and cannot be handled in time, the machine can be shut down for treatment. When it is confirmed that it can work, it can be put into use.
  • Check the oil pressure of the governor. If the oil pressure is low, the cooling water hydraulic valve may be closed.
  • Check whether there is abnormal sound in fag bearing and whether the swing of fag bearing is abnormal.
  • Take an oil sample to observe whether the oil color changes, and conduct laboratory tests to see whether it deteriorates. If the deterioration is confirmed, stop the machine and replace the oil.
  • Check whether the oil level of the oil pointer is normal.
    If not, check whether the oil drain valve of the oil tank is tightly closed. If it has been closed tightly, it should be filled with oil. If it is the leakage of sealant gasket, it should be shut down for treatment.
