The dynamic and static pressure spindle is a special bearing structure, which is mainly characterized in the following aspects:
1、 Structural characteristics
Roller structure: The bearing structure components of the dynamic and static pressure spindle are mainly composed of an inner ring, an outer ring, and rollers. This structure can meet the requirements of high-speed rotation, high-precision positioning, and high reliability.
Dynamic and Static Pressure Oil Film Support: The dynamic and static pressure main shaft forms a static pressure bearing oil film by injecting constant pressure oil into the bearing. At the same time, the dynamic pressure effect is utilized to generate a dynamic pressure oil wedge when the main shaft rotates, jointly achieving support and rotation of the main shaft. This structure enables the dynamic and static pressure spindle to maintain stability and good rigidity during operation.
2、 Performance characteristics
Efficient transmission: The effective contact area of the rollers in the bearing structure of the dynamic and static spindle is large, which can reduce friction and improve transmission efficiency.
High precision positioning: The bearing structure components of the dynamic and static pressure spindle have high-precision positioning functions, which can meet the requirements of high-precision positioning and ensure the accurate positioning of various parts of the mechanical components.
High load-bearing capacity: The dynamic and static pressure main shaft is supported by an oil film, which can maintain a high load-bearing capacity at any shaft speed, suitable for heavy loads, heavy cutting and other occasions.
High rigidity: The dynamic and static pressure spindle can maintain stability during operation, with high rigidity, which can improve machining accuracy and surface smoothness.
Good stability: The dynamic and static pressure spindle adopts a wear-resistant design, and the rotation of the spindle is achieved through oil film support, reducing the occurrence of wear and failure, and having good stability.
3、 Applicable fields
The dynamic and static pressure spindle is widely used in high-precision, high-efficiency, heavy-duty, heavy cutting, wide grinding wheel, multi grinding wheel and other fields, especially in high-precision CNC grinding machines. In addition, it is also suitable for machining machine tool spindles such as centerless grinding and roll grinding, as well as high-precision components such as high-precision spindles, screws, turntables, and guide rails.
In summary, the dynamic and static pressure spindle has unique structural characteristics and excellent performance, and has broad application prospects in the field of mechanical processing.
