It is equal, length diameter more than the bolt of the guide groove in axial direction.
Preferably, the quantity of the guide groove is three, and the quantity of the correspondence bolt is three.
Compared to existing technology, the beneficial effects of the utility model are：Running accuracy is high during gear drive, and device is steady
It is fixed.
Brief description of the drawings
Fig. 1 is the schematic diagram of the gear drive that the utility model one eliminates gap.
Fig. 2 is the exploded view of Double-gear in the gear drive in the elimination gap shown in Fig. 1.
Fig. 3 is the opposite side of the exploded view of Double-gear in the gear drive in the elimination gap shown in Fig. 2.
Specific embodiment
Below, with reference to accompanying drawing and specific embodiment, the utility model is described further：
Such as Fig. 1 to 3, a kind of gear drive for eliminating gear clearance, including individual gears 1 and Double-gear 2, individual gears 1
The number of teeth with Double-gear 2 is coincide, and the inner side of individual gears 1 is provided with sleeve 11, for fixed gear shaft.Double-gear 2 includes first gear
21 and second gear 22, first gear 21 is equal with the diameter and the number of teeth of second gear 22, and the inner side of second gear 22 is provided with gear
Axle sleeve 221, first gear 21 is enclosed within gear bush 221, and guide groove 211 is uniformly provided with first gear, and fixture 23 is passed through and led
Axially slidable be fixed in second gear 22 first gear 21 by groove 211, and first gear is uniformly provided with first gear 21
Groove 212, second gear 22 is provided with the second gear groove 222 corresponding with first gear groove 212, first gear groove
212 and second gear groove 222 opening it is relative form an accommodation space, be equipped with elastic component in the accommodation space.
When individual gears 1 are by being just changed into reversion, there are problems that gear back clearance, the effect of first gear 21 and second gear 22 in elastic component
The trend for rotating in an opposite direction is deposited under power, under the active force of first gear 21 and second gear 22, is eliminated in engagement process
Gear clearance.
In the present embodiment, the elastic component is to be provided with a locating part 25, the first tooth in spring 24, second gear groove 222
The one end for taking turns groove 212 is provided with the through hole being adapted with locating part 25, and spring 24 is limited in the accommodating sky by locating part 25
Between.Fixture includes bolt and nut, and guide groove 211 is in the width of radial direction and the equal diameters of bolt, length of the guide groove 211 in axial direction
Degree more than bolt diameter so that first gear 21 be fixed in second gear 22 and along second gear 22 radially slidably.
When gear is by being just changed into reversion, under the active force of spring 24, first gear 21 has with second gear 22 and turns round about
Dynamic trend, so as to eliminate the gear clearance present in Meshing Process of Spur Gear.Preferably, the quantity of guide groove 211 is three, right
Answer the quantity of bolt 23 for three, the size according to load determines the quantity of spring and the parameter of spring, makes whole device more
Stabilization.
Double-gear 2 is rotated under the control of external equipment, drives four individual gears 1 to rotate, between each two individual gears 1
Double-gear 2 is provided with, during gear is by being just changed into reversion, gap present in Meshing Process of Spur Gear is eliminated, makes angle of rotation
Degree is more accurate.
The gear drive in elimination gap described in the utility model sets Double-gear between individual gears, between Double-gear
There is rightabout active force, shell eliminates the gear clearance by being just changed into during reversion during gear drive, running accuracy is high,
Device stabilization.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
It is corresponding to change and deformation, and all these change and deformation should all belong to the protection of the utility model claim
Within the scope of.
