Although the bearing is metal, it will also be damaged. No matter what hard material it is, it will be damaged, but the degree of damage is different. We all know that the bearing is of good quality and made of good steel. Steel is a very solid material, but it will also be damaged.
The rotary table bearing runs in the machine every day, and it is easy to damage the bearing due to constant friction, so we should also prevent the damage of the bearing, We should maintain the bearing well and do not use the bearing indiscriminately, which will cause unnecessary losses to ourselves.What precautions should be taken to prevent Timken rotary table bearing configuration operation
Timken bearing is to ensure that it can produce excessive deformation during installation. It is also necessary to do from these aspects. There are many things to do for the bearing. Here are the effects of those aspects that need to be paid attention to.
What precautions should be taken to prevent Timken rotary table bearing configuration operation
The roundness of shaft and seat hole and the perpendicularity of retaining shoulder shall be required according to the corresponding accuracy of bearing.What precautions should be taken to prevent Timken rotary table bearing configuration operation
It is necessary to accurately calculate both the interference amount of the rotating ferrule and the appropriate amount of the fixed ferrule. The burning interference of rotating ferrule should also be small within the possible range. As long as the influence of thermal expansion under working temperature and centrifugal force under high speed are ensured, the creep or sliding of tight fitting surface will not be caused.
According to the working load and bearing size, the fixed ring selects a very small clearance fit or interference fit. Too loose or too tight is not conducive to maintaining the original accurate shape.What precautions should be taken to prevent Timken rotary table bearing configuration operation
If the bearing operates at high speed and the working temperature is high, special attention should be paid to the matching of the rotating ring not to be too loose to prevent eccentric vibration, and the matching of the fixed ring should not have clearance to prevent the ring from deforming and exciting vibration under load.What precautions should be taken to prevent Timken rotary table bearing configuration operation
The condition of small interference fit for the fixed ring is that both sides of the matching surface have high shape accuracy and small roughness, otherwise it will be difficult to install and more difficult to disassemble.
In addition, the influence of thermal elongation of the main shaft needs to be considered.What precautions should be taken to prevent Timken rotary table bearing configuration operation
for the main shaft with paired double angular contact ball bearings, the half load is light. If the fit interference is too large, the internal axial preload will be significantly too large, resulting in adverse effects.
The spindle with double row short cylindrical roller bearing and the spindle with rotary table bearing have relatively large load, so their fitting interference is also relatively large.What precautions should be taken to prevent Timken rotary table bearing configuration operation
From the perspective of rotation, Timken bearing should pay attention to the above situations in terms of configuration, but whether the temperature is stable or not should be considered.
The main aspect is how the rotary table bearing should cooperate with its device effect.What precautions should be taken to prevent Timken rotary table bearing configuration operat
