Description
Technical field
The present invention relates to gear transmission technology fields, more specifically, it relates to a kind of motor and its driving wheel installation knot
Structure.
Background technique
The operation of electric operator mainly drives capstan drive, the transmission of driving wheel and driven wheel by motor
Often there is certain gaps.It is larger in the drive gap of driving wheel and driven wheel but when electric motor starting or reversion
When, impact is generated, noise is issued；When driving wheel and driven wheel are gear, deposited between driving gear and the tooth of driven gear
In back lash, when electric motor starting or reversion, when the back lash of driving gear and driven gear is larger, punching is generated
It hits, issues noise, when gear backlash is smaller, gear engagement is easy to appear biting teeth phenomenon, damages the form of gear tooth.
Application No. is 2009101047381 patent documents to disclose a kind of noise-reduction gear combination, in the middle part of driven gear
Center is extended outward to form, equipment gear is cased in the center, is opened on the end face of the driven gear face equipment gear
There is annular groove, is inserted into positioning column on the end face of the equipment gear face driven gear, which is located in annular groove,
It is provided with limited post on the driven gear, which passes through annular groove and protrude into the limit hole opened on equipment gear end face
Interior, which is greater than the diameter of limited post, the limited post can the side-to-side movement in limited block, the annular groove is built-in
There is the annular flat spring with opening, which is against on positioning column and limited post respectively；Outside the center
Periphery and the opposite annular groove opened of equipment gear inner peripheral surface are provided with same circlip；The equipment gear face driven gear
End face be step surface that periphery is lower than middle part, end face in the middle part of the annular groove face equipment gear, the driven gear face
The end face periphery of equipment gear is higher than middle part and equipment gear step surface is adapted.The gear assembled structure is in annular flat spring
Under effect, the gap of driving gear and driven gear is eliminated, reduces the generation of noise, but the mechanism needs equipment gear
Cooperation, its structure is complicated and assembly it is comparatively laborious.
The patent document that application publication number is CN103671831A discloses a kind of eliminations and eliminates between wheel and rack engages
The identical gear of two moduluses is combined by torsional spring and is engaged with rack by the bidentate wheel construction of gap, the structure, two moulds
Referred to as driving gear connect in the identical gears of number with driving mechanism, another is referred to as driven gear, driving gear and from
Processing mounting holes on two opposite end faces of moving gear, the both ends of torsional spring are inserted into respectively in two mounting holes, make driving gear
The power of reverse rotation is generated when being engaged with rack with driven gear, between driving gear and driven gear.The structure can be effective
Elimination wheel and rack back lash, eliminate rack pinion in idle stroke.But the bidentate wheel construction is to gear
Fitness requirement between driven driven gear is relatively high, stringenter to the Sizing requirements of tooth and tooth socket, separately
Outside, there are the risks of mechanical gear latch for the mechanism.
Summary of the invention
In view of the deficienciess of the prior art, the invention reside in a kind of motor and its active wheel mounting structure is provided, it is excellent
Between gesture is that the active wheel mounting structure can eliminate the transmission between driving wheel and driven wheel in electric motor starting or reversion
