The present invention solves the problems of the technologies described above adopted technological scheme: a kind of gap adjusting method that disappears of gear drive, between input gear and output gear, anti-backlash mechanism is set, and input gear is divided into the first input gear and second input gear of coaxial setting, described anti-backlash mechanism comprises adjustment ring, adjustment plate and clearance elimination gear group, described adjustment ring is arranged on the first described input gear, described adjustment plate is arranged on the second described input gear, described adjustment ring is set in the outside of described adjustment plate, the first described input gear is connected with one end of driving gear set, described output gear is connected with the other end of driving gear set, first input gear, driving gear set and output gear form the first Transmitted chains, the second described input gear is connected with one end of clearance elimination gear group, described output gear is connected with the other end of clearance elimination gear group, second input gear, clearance elimination gear group and output gear form the second Transmitted chains, the velocity ratio of the first described Transmitted chains is identical with the velocity ratio of the second described Transmitted chains, described adjustment plate arranges at least one piece of spacing block set, the side of the spacing block set described in every block arranges first screw, described adjustment ring arranges first screw corresponding to the first described screw, the regulating method of the first described screw comprises the following steps:
1) first confirm that the free end of the first screw does not contact with spacing block set;
2) rotate adjustment first screw, make the free end of the first screw and a side contacts of spacing block set, continue adjustment first screw, adjustment plate and adjustment ring are produced relative rotation, until output gear remains static.
Preferably, the opposite side of the spacing block set described in every block arranges one for the second locking screw, described adjustment ring arranges second screw corresponding to the second described screw, and the first screw and the second screw are alternately distributed along the circumference of adjustment ring, the regulating method of the second described screw is: after rotation adjustment first screw makes output gear remain static, first confirm that the free end of the second screw does not contact with spacing block set, then adjustment second screw is rotated, its free end is contacted with the opposite side of spacing block set, continue adjustment second screw, until adjustment plate holds out against by the second screw.During gear drive work, vibrations are inevitable, and after Long-Time Service, the first screw can produce loosening, arranges and regulates the second screw, can play locking effect to the first screw.
Compared with prior art, the invention has the advantages that: the gap adjusting method that disappears of gear drive of the present invention is simple to operate, only need rotate adjustment first screw, drive gap can be eliminated, easy to operate, flexible, significantly can improve the transmission accuracy of gear drive.After gear drive Long-Time Service, if produce new drive gap because of the teeth portion wearing and tearing of gear, only said method need be adopted to re-start the gap that disappears, simple and convenient.

Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.
Example is set to the loading drive gear of three grades of transmissions, the present invention's gap adjusting method that disappears is adopted to eliminate drive gap between its coupling gear, the gap that specifically disappears adjusting method is: as shown in the figure, anti-backlash mechanism 4 is set between input gear 1 and output gear 3, and input gear 1 is divided into coaxial the first input gear 11 and the second input gear 12 arranged, this anti-backlash mechanism 4 comprises adjustment ring 5, adjustment plate 6 and clearance elimination gear group 7, clearance elimination gear group 7 is assemblied on transition axis 71, adjustment ring 5 is arranged on the first input gear 11, adjustment plate 6 is arranged on the second input gear 12, adjustment ring 5 is set in the outside of adjustment plate 6, driving gear set 2 is assemblied on transition axis 21, first input gear 11 is connected with one end of driving gear set 2, output gear 3 is connected with the other end of driving gear set 2, first input gear 11, driving gear set 2 and output gear 3 form the first Transmitted chains 13, second input gear 12 is connected with one end of clearance elimination gear group 7, output gear 3 is connected with the other end of clearance elimination gear group 7, second input gear 12, clearance elimination gear group 7 and output gear 3 form the second Transmitted chains 14, the velocity ratio of the first Transmitted chains 13 is identical with the velocity ratio of the second Transmitted chains 14, adjustment plate 6 arranges at least one piece of spacing block set 61, the side of every block spacing block set 61 arranges first screw 8, adjustment ring 5 arranges first screw 81 corresponding to the first screw 8, one is arranged for the second locking screw 9 at the opposite side of every block spacing block set 61, adjustment ring 5 arranges second screw 91 corresponding to the second screw 9, and the first screw 8 and the second screw 9 are alternately distributed along the circumference of adjustment ring 5, the regulating method of this first screw 8 comprises the following steps:
