Abstract
A kind of anti backlash gear, including gear and gear monolithic, the side of gear is equipped with annular groove, shaft shoulder set is socketed on the shaft shoulder of groove inner ring, shaft shoulder set upper outside edge is fixed with connecting plate, the center of gear monolithic is equipped with central axis, the end rotation connection of central axis and connecting plate, the gear teeth of gear monolithic and the interior friendship of the gear teeth outer rim of gear.The utility model structure is simple, and shaft shoulder set is socketed on the shaft shoulder, without excessively adjusting the magnitude of misalignment of gear Yu gear monolithic, reduces assembly time and difficulty, while achieving the purpose that noise reduction environmental protection again.
Description
Technical field
The utility model relates to field of gears more particularly to a kind of anti backlash gears.
Background technique
In conventional gears transmission, a pair of intermeshing gear, is to tightly engage in the working face flank of its tooth that is meshed
Without sideshake, and there is certain sideshake in the other side non-working surface of the tooth, different transmission gear structures have different flanks
Gap requirement, for this purpose, be all in the past strict control sideshake during manufacturing, nevertheless, still can't resolve the big problem of noise, and
Existing anti backlash gear is assembled by gear, monolithic gear, straight pin, pressure spring, shaft block ring etc., and there are volumes
Greatly, the technical problems such as assembly technology complexity, moreover, when processing gear, monolithic gear, process is also more complex, at
This height has that structure is complicated using cylindrical pressure spring come the magnitude of misalignment of adjustment gear ontology and monolithic gear, and poor reliability lacks
Point.
Summary of the invention
The utility model is to solve the above problems, provide that a kind of structure is simple, anti backlash gear easy to process.
Technical solution adopted in the utility model:
The side of a kind of anti backlash gear, including gear and gear monolithic, gear is equipped with annular groove, groove
Shaft shoulder set is socketed on the shaft shoulder of inner ring, shaft shoulder set upper outside edge is fixed with connecting plate, and the center of gear monolithic is equipped with central axis, in
It is handed in the rotation connection of the end of mandrel and connecting plate, the gear teeth of gear monolithic and the gear teeth outer rim of gear.
The rubber ring of rubber material is lined between the shaft shoulder set and the shaft shoulder, the inside and outside anchor ring of rubber ring is provided with anti-skid chequer.
One end that the central axis of the gear monolithic is connect with connecting plate is towards gear.
The utility model has the beneficial effects that the utility model structure is simple, shaft shoulder set is socketed on the shaft shoulder, does not have to excessive adjust
The magnitude of misalignment of whole gear and gear monolithic reduces assembly time and difficulty, while achieving the purpose that noise reduction environmental protection again.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein: 1- gear；2- gear monolithic；3- central axis；4- connecting plate；5- groove；6- shaft shoulder set；7- rubber
Ring；The 8- shaft shoulder.
Specific embodiment
The side of a kind of anti backlash gear, including gear 1 and gear monolithic 2, gear 1 is equipped with annular groove 5,
Shaft shoulder set 6 is socketed on the shaft shoulder 8 of 5 inner ring of groove, the shaft shoulder covers 6 upper outside edges and is fixed with connecting plate 4, and the center of gear monolithic 2 is set
There are central axis 3, the end rotation connection of central axis 3 and connecting plate 4, the gear teeth of gear monolithic 2 and the gear teeth outer rim of gear 1
Interior friendship.
The rubber ring 7 of rubber material is lined between the shaft shoulder set 6 and the shaft shoulder 8, the inside and outside anchor ring of rubber ring 7 is provided with anti-skidding
Line.
One end that the central axis 3 of the gear monolithic 2 is connect with connecting plate 4 is towards gear 1.
When work, when this anti backlash gear engages between gear pair be driven gear, when driving gear and this without sideshake tooth
When wheel engagement, gear monolithic 26 is socketed on the shaft shoulder 8 by shaft shoulder set, between be equipped with rubber ring 7 so that the attachment of gear monolithic 2
It is operated in gear 1, the active field of conjugate action of driving gear first is engaged with the working face of gear 1, with backgear list
2 non-working surface of piece is engaged with the non-field of conjugate action of driving gear, is driven to realize without sideshake.
One embodiment of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment should not be considered as limiting the scope of the present invention.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should still belong within the patent covering scope of the utility model.
