Why we need to order the turntable bearing?

The turntable bearing is widely used in machinery. Some turntable bearing parts used in this kind of construction machinery are also widely used in some places at the beginning, such as some earth moving machinery, some excavators, even some disintegrators, some graders and a large number of road rollers, It can even be used on dynamic compactors, roadheader and other machines.

What items are included in the routine inspection of turntable bearings?

1. Regularly check the flexibility of the rotation; if noise and impact are found, it should be stopped immediately for inspection, troubleshooting, and dismantling and inspection if necessary;

2. Regularly check whether the rotating ring gear is cracked or damaged, and whether the meshing tooth surface has occlusion, gnawing, tooth surface peeling, etc.;

3. Regularly check the integrity of the seal. If the sealing belt is found to be damaged, it should be replaced in time. If it is found to fall off, it should be reset in time.

What are the precautions for the detection of turntable bearing?

Due to the difference in the position of the dial indicator fixed by different people, the measurement value will change. Therefore, measuring and recording several times will ensure the accuracy of the data!

In addition, I remind the owners that the turntable bearing clearance also has a standard value. If the clearance is maintained at 0.5-3mm, it is normal. If it exceeds, it means that everyone needs to check whether it needs to be repaired or replaced!

What are the effects of the structural rigidity of the turntable bearing?

The turntable bearing is an important component that transmits various loads between the turntable and the chassis. Its rigidity is not large, and it mainly depends on the structural rigidity of the chassis and the turntable supporting it. Theoretically, the ideal structure of the turntable is a cylindrical shape with high rigidity, so that the load on the turntable can be evenly distributed, but it is impossible to achieve due to the height limitation of the whole machine. The finite element analysis results of the turntable show that the deformation of the base plate connected to the turntable and the turntable bearing is larger, and it is more serious under the condition of large eccentric load, which causes the load to concentrate on a small part of the rollers, thereby increasing the load of a single roller. In particular, the deformation of the turntable structure will change the contact between the rollers and the raceway, greatly reducing the contact length and causing a significant increase in contact stress. However, the calculation methods of contact stress and static capacity that are widely used at present are based on the premise that the turntable bearing is uniformly stressed and the effective contact length of the roller is 80% of the length of the roller. Obviously, this premise is not in line with the actual situation. This is another reason why the turntable bearing is prone to damage.
