Because the ball screw pair of inverse transmission efficiency is very high, reverse transmission can lock, so when it is in the vertical settlement must be equipped with brakes, other when stop running in order to prevent the servo motor, the moving parts due to gravity and the inverse transmission, also can prevent the accident caused by accidental factors.

for Z direction using one-way non-return CNC carving and milling machine tool bearing to prevent the feed screw inverse transmission schematic diagram of the brake mechanism. Z to the servo motors to drive the Z axis screw by the elastic coupling, the rise and fall of Z to the workbench. To prevent the workbench and the result of the weight of the spindle components are key components of the inverse transmission one-way non-return bearings and friction damping device ( By coupling sleeve, friction ring, disc spring, adjusting nut, etc) 。 One-way non-return bearing allows only one direction, while the other direction to stop. One-way non-return bearing inner ring and screw top fixed connection, the outer ring with key link set together. When the workbench rise, one-way non-return like plain bearing, bearing no non-return, servo motor drives the ball screw rotation and nut drive the workbench upward movement. When the servo motor stop running, Motor with brake) , workbench to decline due to gravity, nut has the inverse transmission, drive screw rotation at this point, the one-way non-return bearing inner ring and ball will drive bearing outer ring reverse rotation. For one-way non-return bearing outer ring by key and friction damping device together, outer ring by friction damping device produces friction torque braking, thereby preventing the inverse transmission. Prevent reverse friction torque transmission can be achieved by the size of the nut. The disadvantage of this structure is on the vertical downward transmission, must overcome this additional plus the friction torque.

by CNC engraving machine co. , LTD production of outer diameter with retaining the keyway one-way non-return bearing, simple and compact structure, can withstand the load is large, flexible rotation, after used on many sets of CNC carving and milling machine tool shows that its non-return reliability and non-return precision are better than ordinary overrunning clutch.
