Between there are angular velocity differences, exist between wavers cylinder and wavers axis and relatively rotate, exist between wavers cylinder and axle sleeve opposite
Rotation, in relative rotational motion, since the half of ball is in the cambered surface location indentations of ball locating piece, ball it is another
Half in annular groove, and when ball is moved along annular groove, ball drives string by the cambered surface location indentations of ball locating piece
Inking roller cartridge is moved axially relative to wavers axis, to realize the circumferential movement and axial motion of wavers cylinder, knot simultaneously
Structure is simple, reduces difficulty of processing, and go here and there not generate between black gear and wavers axis and slide axially, and extends making for the black gear of string
Use the service life.In addition the length that the annular groove of axle sleeve projects in the horizontal plane determines the amplitude of wavers cylinder axial motion, so as to
The size of string quantity of motion is adjusted to replace different axle sleeves as needed.
As the preferred embodiment of the utility model, the axle sleeve is integrally formed with the wavers axis.
The utility model compared with prior art, has the following advantages that：
It is rotated by driving roller and drives wavers cylinder circumferential movement, pass through the transmission gone here and there between black gear and transmission gear
It drives wavers axis and axle sleeve thereon to synchronize and carries out circumferential movement, since there are angular speed between wavers cylinder and wavers axis
Exist between difference, wavers cylinder and wavers axis and axle sleeve thereon and relatively rotate, in relative rotational motion, due to ball
Half is in the cambered surface location indentations of ball locating piece, and the other half of ball is in annular groove, and ball is positioned by cambered surface
Recess portion drives wavers cylinder to be moved axially relative to wavers axis, to realize the circumferential movement and axis of wavers cylinder simultaneously
It is simple in structure to vibration, difficulty of processing is reduced, and go here and there not generate between black gear and wavers axis and slide axially, extends string
The service life of black gear.
Description of the drawings
