Reducer of drive of electric machinery of working principle communication rotates tub wheel, circumferential curve chamfer passes tub wheel all cloth drives the arm that change a knife to rotate in 6 gyro wheel on axis of drive of the arm that change a knife, in the meantime, linkage of chamfer of cam of tub wheel end panel dials fork, around shift pull rod, make change axis of drive of knife arm edge (spline axis) around is mobile, the structure sees figure below. 2.

Typical breakdown handles a 1 process that change a knife in, the arm that change a knife not movement, electric machinery rotates from beginning to end, coder numerical value is changeless. Breakdown reason is reducer safety clutch skids, although electric machinery rotates, but reducer take-off is not rotational. Ravel reducer, adjust clutch attrition flat spring force or change attrition piece. Exemple deflection of null of the 2 arms that change a knife, when null, coder numerical value is true, but the arm that change a knife is absent actually null and not stable. Breakdown reason is reducer safety clutch did not remove safety to protect action, the key of transmission part coupling that brings about tub wheel of the drive inside the orgnaization to rotate is cut, or axis of drive of the arm that change a knife becomes loose (awl covers locking) , although coder transmission shaft rotates reach the designated position, but tub wheel did not reach the designated position and null is not stable. Disassemble the orgnaization that change a knife, change to be cut to bolt, or when all be in null with the arm that change a knife in tub wheel, locking changes axis of knife arm drive. 3.

Reshipment measure and note (1) affirmatory null gyro wheel. If have null number, criterion null gyro wheel is gyro wheel of correspondence of mark of null of end panel of axis of drive of the arm that change a knife. If the label is unidentified,do not have a label, need to rotate 6 gyro wheel respectively to horizontal position, cover on the arm that change a knife, the gyro wheel that makes the arm that change a knife is in null is null gyro wheel namely. (2) gyro wheel of null of axis of drive of the arm that change a knife and correspondence of interval of tub wheel null are installed. (3) had held the arm that change a knife, the hand uses dish of electric machinery, observe whether movements of the arm that change a knife is normal, it is normal to be like, new demarcate changes knife arm null and make its are in null interval roughly mid. (4) add gear oil to the middle of casing of the orgnaization that change a knife, try machine. CNC Milling
