Servo motor and feed screw connection structure

In CNC carving and milling machine tool feed system, servo motor and ball screw connection to ensure the transmission zero clearance, pulse instructions that are executed in this way can we accurately, without losing pulse deals & other; Out-of-step & throughout; 。 In CNC carving and milling machine tool, the X, Y and Z axis adopts straight association-like, namely through one-way diaphragm elastic keyless coupling, unite the servo motor and ball screw. For one-way diaphragm elastic coupling used when tight coupling, completely eliminate the running clearance, the motor shaft and screw are spline shaft, is conducive to the balance of high-speed rotation, elastic coupling loading and unloading is very convenient. Lead screw and the coupling of the servo motor can see in figure 1, figure 2.
