Advantages of sliding bearing spindle
Sliding bearing spindles are widely used in high-speed, heavy load, high-precision machine tools and other fields due to their excellent materials, reliable fixing methods, and compact structure. The specific advantages are:
High transmission torque
Compared with rolling bearing spindles, sliding bearing spindles can bear larger radial loads and torques due to their higher proportion of complete contact surfaces, making them suitable for machine tools with larger transmission torques.
High precision
The manufacturing process of sliding bearing spindle requires high levels of dimensional accuracy, positional accuracy, and surface roughness. Therefore, during high-speed operation, it eliminates fit gaps, reduces vibration and noise, and ensures the accuracy and surface quality of workpiece processing.
Good stability
The sliding bearing spindle, due to its complete surface contact, reduces the changes in eccentric force or friction caused by ball damage or ball cage damage in rolling bearings, and improves its stability and reliability.
Disadvantages of sliding bearing spindle
Although sliding bearing spindles have many advantages, they also have their drawbacks, such as:
1. High friction loss
When the sliding bearing spindle is in motion, the friction between the surfaces will cause energy loss and generate heat. This will cause heating and wear of the friction surface. Although lubrication can reduce friction resistance and wear, it also increases the requirement for lubricating oil and requires regular replacement and maintenance.
2. Strict lubrication conditions
The sliding bearing spindle has a high requirement for lubricating oil, and poor lubrication can easily lead to spindle overheating and shortened lifespan. At the same time, during high-speed rotation, hydraulic oil or oil film pressure may fluctuate, causing electric discharge on the friction surface due to field strength. Therefore, the lubrication conditions of the sliding bearing spindle are more stringent.
3. High vibration and noise
Compared with rolling bearings, the main spindle of sliding bearings produces friction sound and machine tool vibration during high-speed rotation due to the complete contact between its surfaces, which affects machining accuracy and production efficiency.
In summary, the sliding bearing spindle has advantages such as large transmission torque, high accuracy, and good stability, but it also has disadvantages such as large friction loss and harsh lubrication conditions. In practical applications, it is necessary to choose and maintain according to specific needs.
