The inner and outer rings of the bearing are separated, and the center of the thrust can be well centered after assembly, while the side thrust is very poor in centering effect, which is greatly affected by the technical level of the assembly workers. The larger the axial amount, the worse the centering effect is. The small amount of the string causes the bearing to overheat, and the precision of the domestically produced thrust bearing is poor. There is no regulation on how long it takes to re-adjust the amount of resources. If the axial string is too large, the axis is not well positioned. At the same time, the unit is vibrating in the reciprocating machine. When the amplitude reaches a certain value, it may impact the broken teeth.
The coupling diaphragm is under compression, and the axial thrust of the high-speed shaft of the reduction box happens to be pushed to the coupling, so that the axial thrust is received by the coupling diaphragm, and the thrust bearing is very small, even It does not withstand axial forces, so the centering effect at the high speed shaft coupling is extremely poor. When the coupling is installed, it is allowed to have a different center of 011mm. Here, the vibration source of the gearbox is generated. From the perspective of gear damage for many years, it has also been proved that the gears are dismantled on the side of the large gear compressor. Before the transformation, the couplings are hammered down by hand and the installation clearance is negative.
When the reducer is rebuilt, we consider the stock spare parts, and the size coordination is more on the retaining ring and the bearing gland to ensure that the spare parts can still be used. After the gear is dismantled, it should be analyzed comprehensively. It should not be used to find the cause of the problem. Especially at this stage, the imported equipment spare parts mainly rely on domestic production, which may cause problems due to the quality of other spare parts. Therefore, it is very important and necessary for the on-site maintenance personnel to correctly determine the cause of the failure and take corresponding measures.
Barbell bar a long bar which is used in barbell, one kind of exercise tools used in weight training, bodybuilding, weightlifting and powerlifting. The barbell bar length ranges from 1200mm to 2400mm. The barbell bar diameter ranges from 25mm to 50mm. The barbell bar can be used for both competitive sports such as powerlifting, Olympic weight lifting, CrossFit. and other exercises such as bicep curl, bench press, overhead press, deadlift, and squat etc.
Among the various barbell bars, 20kg barbell bar is the most popular and standard barbell bars.
