The clearance of machine tool bearing is an important factor affecting the accuracy and life of machine tool. This paper will introduce the concept and function of machine tool bearing clearance, as well as the methods and skills of clearance adjustment.
The concept and function of machine tool bearing clearance
The clearance of the machine tool bearing refers to the relative range of motion between the inner ring and the outer ring during the operation of the bearing. The size of the clearance directly affects the running accuracy, vibration and noise of the bearing. Reasonable clearance can ensure the normal operation of the bearing and improve the accuracy and life of the machine tool.
The method and skill of adjusting the bearing clearance of machine tool
Use the clearance adjustment tool
The clearance adjustment tool is a special tool for adjusting the bearing clearance, including a lever gauge, a dial gauge, a feeler, etc. When using the clearance adjustment tool, you need to choose the right tool according to the type and structure of the bearing, and follow the instructions for using the tool. Before adjustment, check and adjust the tool to ensure its accuracy and reliability.
Determine the effect of clearance adjustment
When adjusting the bearing clearance, it is necessary to determine the appropriate clearance value according to the actual situation and requirements of the machine tool. After the adjustment is complete, you need to use the corresponding detection tool to detect the clearance value to determine whether the adjustment effect meets the requirements. If it does not meet the requirements, it needs to be adjusted again.
Adjust the method again
If the initial adjustment does not meet the requirements, it needs to be adjusted again. When adjusting again, appropriate adjustment methods can be adopted according to the specific circumstances. For example, the bearing clearance can be adjusted by increasing or decreasing the bearing gasket and adjusting the bearing seat. During the adjustment process, care should be taken not to damage bearings and other components to ensure the normal operation of the machine tool.
Precautions for machine tool bearing clearance adjustment
Before adjusting the bearing clearance, it is necessary to conduct a comprehensive inspection of the machine tool to determine whether the clearance needs to be adjusted.
During the adjustment process, it is necessary to keep it clean and dry to avoid impurities such as dust and water entering the bearing interior.
During the adjustment process, follow the instructions for using the tool to avoid damage to bearings and other components caused by improper use.
After the adjustment is completed, it is necessary to test the machine tool to check whether the running condition and noise of the bearing meet the requirements.
The clearance adjustment of machine tool bearing is an important link to ensure the normal operation of machine tool. The accuracy and life of the machine can be improved by reasonable clearance adjustment. In actual operations, you need to select appropriate adjustment methods and tools according to the actual situation, and follow the precautions for adjustment. Only in this way can we ensure the normal operation of the machine tool and extend the service life.
