In order to reach above purpose, this kind transverse-cutting-machine gear side-gap regulation mechanism provided by the invention, comprise: upper cutter shaft spindle nose, the upper slitter gear, transfer the gap gear, wherein, described upper slitter gear and accent gap gear are sheathed on the cutter shaft spindle nose successively, and fix by the end cap of upper cutter shaft spindle nose end face setting, fix by set bolt between described upper slitter gear and the accent gap gear, be provided with the wedge key that limits for side direction between described spindle nose and upper slitter gear and the accent gap gear, described wedge key is fixed on the cutter shaft spindle nose, and the side of described wedge key is the inclined-plane, is provided with voussoir between described inclined-plane and the accent gap gear, described voussoir is scalariform, and described voussoir outer end is provided with adjusting bolt.
Further, the set bolt between described upper slitter gear and the accent gap gear is 4;
Further, described end cap is fixed on the end face of upper cutter shaft spindle nose by 4 bolts;
Further, described wedge key comprises the first wedge key and the second wedge key, and described the first wedge key and the second wedge key be symmetrical being fixedly arranged on the spindle nose of cutter shaft up and down;
Further, described voussoir comprises the first voussoir, the second voussoir, the 3rd voussoir, the 4th voussoir, and described the first voussoir and the second voussoir are located at respectively the both sides of the first wedge key, and described the 3rd voussoir and the 4th voussoir are located at respectively the both sides of the second wedge key.
When adjusting gear backlash, at first unclamp the set bolt between upper slitter gear and the accent gap gear, and then unclamp the adjusting bolt of all voussoir outer ends, adjust as required again the adjusting bolt of two voussoirs at diagonal angle, such as the first voussoir and the 4th voussoir, perhaps the second voussoir and the 3rd voussoir, described voussoir are subject to after the extruding of adjusting bolt so that transfer gap gear and upper slitter gear to misplace, thereby reach the gap of eliminating with lower cutter tooth wheel, lock adjusting bolt at last and set bolt gets final product.
This kind gear backlash adjusting mechanism provided by the invention, as long as two wedge keys of processing and four voussoirs just can play the gap of eliminating with lower cutter tooth wheel, it is also convenient to adjust, and has reduced cost under the prerequisite that does not affect precision.
