The inner wall of 16 inner end of bearing holder (housing, cover) extends inwardly baffle ring and taper roll bearing 21 is against on the inside of baffle ring；Bearing cap 15 and one
The round nut 23 being threaded in interior tooth shaft 17, round nut 23 and taper roll bearing are equipped between taper roll bearing 21
It is equipped with locked spacer 24 and third axle sleeve 22 between 21, locked spacer 24 and third axle sleeve 22 are locked by round nut 23 so that circle
Taper roller bearing 21 is fixed in interior tooth shaft 17.
Bevel gear 18 is mounted on by key connection in interior tooth shaft 17, and ball bearing 19 is fixed on interior tooth shaft by end ring 20
17 inner end；The gear of 4 inner end of angular wheel shaft is engaged with the bevel gear 18 in interior tooth shaft 17；Second bearing covers 16 outer walls fluting,
Cover 14 be equipped with extend transversely through 14 endoporus side wall of cover be connected in the slot with second bearing set 16 be threadedly coupled it is tight
Gu screw 26.
In the present invention, adjusting nut (including the first adjusting nut 8 and second adjusting nut 25) and bearing holder (housing, cover) (including first
Bearing holder (housing, cover) 9 and second bearing set 16) between connected using fine thread, since thread pitch is small, adjusting nut rotates a circle umbrella
Gear shaft 4 or the axial movement distance of interior tooth shaft 17 are smaller, can play the work of fine tuning angular wheel shaft 4 or 17 axial distance of interior tooth shaft
With so as to intense adjustment bevel gear pair backlash；The helix angle smaller of fine thread, the more conducively self-locking of screw thread, can
Achieve the purpose that it is anti-loosening between adjusting nut and bearing holder (housing, cover), to prevent the axial float of angular wheel shaft 4 or interior tooth shaft 17；Carefully
The intensity of pitch thread also higher, static load ability is big, can bear angular wheel shaft 4 or power that when interior tooth shaft 17 moves axially is required.
Also, to ensure installation accuracy, that is, the endoporus of bearing holder (housing, cover) (including first axle bearing sleeve 9 and second bearing set 16) is installed
(including 14 vertical endoporus of 1 lateral bore of body and cover) cannot cross ambassador's bearing holder (housing, cover) between bearing holder (housing, cover) because of gap radial jump
It is dynamic, so that axis is beated therewith, influences the stationarity of bevel gear back lash and transmission；It can not make bearing because interference fit is excessive
Set moved axially or longitudinally can not be unable to reach the purpose of adjustment backlash；So 1 lateral bore of body or cover 14 are perpendicular
Using accurate transition cooperation between inward hole and bearing holder (housing, cover) outer wall, between the endoporus and bearing holder (housing, cover) that also can guarantee installation bearing holder (housing, cover)
There is higher centering precision, is conducive to the adjustment of backlash.
Meanwhile to ensure to prevent the movement of bearing holder (housing, cover) in the axial direction when adjusting bevel gear pair backlash, on the one hand
By the way of slotting on bearing holder (housing, cover), the inner hole wall of installation bearing holder (housing, cover) (9,16) is passed through to connect using trip bolt (10,26)
Bearing holder (housing, cover) and body 1 or cover 14 are fixed in bearing grooving；On the other hand use bolt, end cap 7 (or bearing cap 15) will
Nut is fixed on body 1 or cover 14.
Determined using a pair of symmetrically arranged taper roll bearing (2,21) on above-mentioned angular wheel shaft 4 or interior tooth shaft 17
Position, the other end are supported using cylinder roller bearing 13 or ball bearing 19.
Another aspect of the present invention additionally provides a kind of method of adjustment adjusting structure based on above-mentioned bevel gear pair backlash,
Including being located at the horizontal adjusting mechanism being connect with angular wheel shaft 4 in 1 lateral bore of body, and it is located in 14 vertical endoporus of cover
The vertical adjustment mechanism being connect with interior tooth shaft 17；Wherein when the backlash is excessive, adjusting vertical adjustment mechanism makes internal tooth
Axis 17 is moved up to reduce backlash；When the backlash is too small, adjusting horizontal adjusting mechanism makes angular wheel shaft 4 to body
It moves to increase backlash 1 lateral bore outer end.
Specifically, when the backlash is excessive, the second adjusting nut 25 is turned, passes through the second adjusting nut 25 and
Fine thread between two bearing holder (housing, cover)s 16 drives second bearing set 16 to be axially moveable；Since round nut 23 passes through locked spacer 24
It is waited with third axle sleeve 22 and taper roll bearing 21 is fixed in interior tooth shaft 17, and interior tooth shaft 17 and second bearing is made to cover between 16
It is relatively fixed connection, so the movement of second bearing set 16 just drives the movement of interior tooth shaft 17；The second adjusting nut 25 is turned, is made
Tooth shaft 17 moves up in obtaining, and achievees the purpose that reduce backlash；
When the backlash is too small, the first adjusting nut 8 is turned, passes through the first adjusting nut 8 and first axle bearing sleeve 9
Between fine thread drive first axle bearing sleeve 9 to be axially moveable；Since round nut 5 passes through locked spacer 6 and the second axle sleeve 3 etc.
Taper roll bearing 2 and cylinder roller bearing 13 are fixed on angular wheel shaft 4, and make angular wheel shaft 4 and first axle bearing sleeve 9 it
Between be relatively fixed connection, so the movement of first axle bearing sleeve 9 just drives the movement of angular wheel shaft 4, turn the first adjusting nut 8,
Keep angular wheel shaft 4 mobile to left end (outer end of 1 lateral bore of body), achievees the purpose that increase backlash.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
