The passive herringbone bear A is packed in by interference fit and flat key on output shaft；The passive herringbone bear B is logical
It crosses clearance fit and flat key is sleeved on output shaft；The compression spring is placed in eight unthreaded holes of the end faces passive herringbone bear B,
The pressing plate is sleeved on the compression spring on output shaft between briquetting nut, and the briquetting nut is screwed onto defeated by screw thread
At threaded shaft section on shaft, the holding screw is withstood on by screw thread on checknut block end face；The output shaft is logical
Bearing is crossed to be placed in the bearing hole of babinet.
Further, working machine solid shafting is fastened in the endoporus of output shaft by the locking plate by bolt.
Further, six unthreaded hole through-hole bolts of the output transparent cover are screwed onto at the hickey of babinet.
Further, four unthreaded holes of the protective cover are screwed onto by bolt at the hickey of output transparent cover.
Further, eight unthreaded holes of the babinet are screwed onto the hickey of working machine mounting plane by bolt
Place.
This reality advantageous effect of the invention：1, high-precision is solved（Angle or position）Gear drive application market demand；2、
It is not very high to Gear Processing required precision, easy to manufacture has saved manufacturing cost；3, equipment adjustment is convenient, and reliability is high, easily
In batch production.

Specific implementation mode
Technical scheme of the present invention is described in further detail with reference to the accompanying drawings of the specification.
With reference to attached drawing：
Herringbone bear of the present invention disappears gap shunting speed reducer, including planetary reducing motor 1, input flange 2, active double helical tooth
Wheel 3, input shaft 4, passive herringbone bear A 5, passive herringbone bear B 6, compression spring 7, pressing plate 8, briquetting nut 9, holding screw
902, checknut block 903, output shaft 10, bearing 11, babinet 12, output transparent cover 13, locking plate 14, protective cover 15.Described
Four unthreaded holes of output flange of planetary reducing motor 1 are screwed onto by bolt at the hickey of input flange 2, the input
Six unthreaded holes of flange 2 are screwed onto by bolt at the hickey of babinet 12, and the active herringbone bear 3 is matched by interference
Conjunction is packed on input shaft 4, and the input shaft 4 is placed on by bearing in the bearing hole of babinet 12.
The passive herringbone bear A 5 is packed in by interference fit and flat key on output shaft 10；Described is moving
Word gear B 6 is sleeved on by clearance fit and flat key on output shaft 10；The compression spring 7 is placed on passive herringbone bear B 6
In eight unthreaded holes of end face, the pressing plate 8 is sleeved between the compression spring 7 on output shaft 10 and briquetting nut 9, the pressure
Block nut 9 is screwed onto by screw thread at the threaded shaft section on output shaft 10, and the holding screw 902 is withstood on locking by screw thread
On 903 end face of threaded block；The output shaft 10 is placed on by bearing in the bearing hole of babinet 12.
Working machine solid shafting is fastened in the endoporus of output shaft 10 by the locking plate 14 by bolt.
Six unthreaded hole through-hole bolts of the output transparent cover 13 are screwed onto at the hickey of babinet 12.
Four unthreaded holes of the protective cover 15 are screwed onto by bolt at the hickey of output transparent cover 13.
Eight unthreaded holes of the babinet 12 are screwed onto by bolt at the hickey of working machine mounting plane.
The double helical tooth gap shunting speed reducer that disappears is driven using 1 associated mode of planetary reducing motor, and planetary reducing motor 1 is solid
Output shaft extend through flat key with input hollow shaft couple, by the active herringbone bear 3 on input shaft, respectively with both sides output shaft
Upper passive herringbone bear A＆B engagements, realize power dividing output；Dual output hollow shaft is by locking plate 14 again by planetary reduction gear electricity
The power dividing of machine 1 passes to two input shaft of working machine.
Double helical tooth disappears gap principle：There are phase requirements when passive herringbone bear A, B processing keyway.Passive herringbone bear A5 passes through
Interference fit and flat key are packed on output shaft, and flat key mainly plays phase bit, and torque is born mainly by interference volume；Passively
Herringbone bear B is sleeved on by clearance fit and flat key on output shaft, and flat key not only plays phase bit, still suffers from gear pair transmission
Torque.When speed reducer assembles, apply axial pre tightening force F to pressing plate by tightening briquetting nut, pressing plate is by compression spring again by axis
Passive herringbone bear B6 is passed to pretightning force F, passive herringbone bear B6 will produce axial shifting under the action of axial pre tightening force F
It is dynamic, while active herringbone bear 3 rotates minute angle on input shaft, keeps passive herringbone bear A＆B and active herringbone bear two-sided
Engagement, reaches elimination gear backlash.At work, compression spring can store gear thermal expansion to speed reducer and lubricating oil film generates jointly
Small axial displacement, and it is to compress checknut block end face by holding screw to realize that briquetting nut 9 is locking.By passive
Herringbone bear A＆B keeps two-sided with active herringbone bear 3 and engages, and realizes speed reducer without the forward and reverse transmission of hysterisis error.
The foregoing is merely the better embodiment of the present invention, protection scope of the present invention is not with the above embodiment
Limit, as long as those of ordinary skill in the art should all be included in power according to equivalent modification or variation made by disclosed content
In protection domain described in sharp claim.
