The inner and outer rings of this bearing are separated, and the centering can be well obtained on the thrust side after assembly, while the centering effect of the auxiliary thrust is very poor, which is greatly affected by the technical level of the assembly workers. The larger the axial string amount, the worse the centering effect. The small string amount causes the bearing to overheat. In addition, the domestic thrust bearing has poor precision and the string amount will be large after running wear. However, there is no regulation on how long it will take to readjust the string quantity. If the axial string is too large, the axis is not well positioned. At the same time, the unit is a reciprocating machine, which will inevitably produce vibration. If the amplitude reaches a certain value, it may impact and break the teeth.

The coupling diaphragm is in a compressed state, and the axial thrust of the high-speed shaft of the reduction gearbox happens to be pushed to the coupling, so that the axial thrust is borne by the coupling diaphragm, and the thrust bearing bears very little, even No axial force, so the centering effect at the high-speed shaft coupling is poor. When the coupling is installed, it is allowed to have a different concentricity of 011mm, and this is the place where the vibration source of the reduction gearbox is generated. Judging from the damage of gears over the years, this is also proved by the removal of teeth on the side of the large gear compressor. Before the transformation, the coupling was hammered down with a hand hammer during overhaul, and the installation clearance was negative.
During the transformation of the reducer, we took into account the stock of spare parts, and worked hard on the retaining ring and bearing gland to ensure that the stock of spare parts can still be used. After the gear is removed, it should be analyzed. It should not simply find the cause of the problem, especially after the imported equipment spare parts mainly rely on domestic production at this stage, it may cause problems due to the quality of other spare parts. Therefore, it is very important and necessary for on-site maintenance personnel to correctly judge the cause of the fault and take corresponding measures.
