In high precision, many excellent characteristics such as high speed characteristics and high abrasion resistance, and ball-screw is various NC Machine Tools Transmission Systems
Key components and parts, improve transmission system sensitivity, in terms of play crucial effect.
2, the method synchronous using the synchronization accuracy and mechanical forced that improve servo motor, i.e., it is same using driving gear set
Mechanical structure is walked, is played from structure to the phase locked positive action of gear on slow-speed shaft, has been effectively eliminated to watching
Taking motor movement interference and power consumption level influences the back lash of maximum small (master) gear and intermediate gear (from), in turn
Between effective solution synchronous servo motor the problems such as movement interference, power loss.
3, double freedom parallel-connection structure, the existing movement of effective solution mechanism with single degree of freedom servo-pressing machine and power
The problem of loss.Mechanism application be Dual-Servo Motor parallel drive mode, effective solution synchronous servo motor and dynamic
The problems such as interference and power loss.It is antisymmetry formula slider-crank mechanism that the upper half of the linkage mechanism, which uses, and raising finishes
Structure rigidity and stability improve the mechanical life of press machine and the stability of press machine executive item power, torque output, and
With preferable control performance.
4, by connecting rod, foot lever and several push rods, multi-stage speed-reducing torsion increasing device is formed, the pressure of press machine is greatly improved
Power.
5, it is driven using Dual-Servo Motor, improves the overall power of press machine.
