This lecture focuses on the mechanical structure characteristics of the feed system.
1, high transmission stiffness
The high transmission stiffness of the feed drive system mainly depends on the stiffness of the screw nut pair (linear motion) or the worm gear (rotary motion) and its supporting parts. Insufficient stiffness together with frictional resistance can cause the table to crawl and cause reverse dead zones, affecting transmission accuracy. Shortening the transmission chain, selecting the screw size, and pre-tightening the screw nut pair and supporting components are effective ways to improve the transmission stiffness.
2. High resonance
In order to improve the anti-vibration performance of the feed system, the mechanical components should have a high natural frequency and appropriate damping. Generally, the natural frequency of the mechanical transmission system should be 2 to 3 times higher than the natural frequency of the servo drive system.
3. Low friction
The feed transmission system requires smooth movement, accurate positioning and good quick response characteristics. It is necessary to reduce the frictional resistance of the moving parts and the difference between the dynamic and static friction coefficients. Ball screw nut pairs are commonly used in feed transmission systems.
4. Low inertia
Because the feed system often needs to start, stop, shift or reverse, if the inertia of the mechanical transmission is large, it will increase the load and degrade the dynamic performance of the system. Therefore, under the premise of meeting the strength and rigidity, the weight of the moving parts and the size of each transmission element should be reduced as much as possible so as to improve the ability of the transmission parts to respond quickly to commands.
5. No gap
Mechanical clearance is another major cause of the reverse dead zone of the feed system. Therefore, all links of the drive chain, including gear pairs, screw nut pairs, couplings and their supporting components, etc., should be eliminated. Structural measures.
