Axle 4 external diameter is equal, and the inwall of the first axle bearing sleeve 9 the inner back-up ring that extends internally out enables cylinder roller bearing 13 to be against in back-up ring
Side；It is arranged with its external diameter spacer 12 equal with first axle bearing sleeve 9 internal diameter outside first axle sleeve 11；End cap 7 and a pair of taper roller
It is provided with the round nut 5 being threaded on angular wheel shaft 4 between bearing 2, be only provided between round nut 5 and taper roll bearing 2
Mobile gasket 6 and the second axle sleeve 3, lock locked spacer 6 and the second axle sleeve 3 by round nut 5 so that cylinder roller bearing 13 and circle
Taper roller bearing 2 is fixed on angular wheel shaft 4.
First axle bearing sleeve 9 outer wall is slotted, and body 1 is provided with and vertically runs through body 1 side wall to be connected in described groove with the
The threaded trip bolt 10 of one bearing holder (housing, cover) 9.
Described vertical guiding mechanism includes the second bearing set 16 being arranged in the vertical endoporus of cover 14, and cover 14 is vertically interior
It is interference fits between hole and second bearing set 16；Internal tooth axle 17 outer end portion in the vertical endoporus of cover 14 is arranged at
It is relatively fixed in two bearing holder (housing, cover)s 16 and with second bearing set 16 and couples, i.e. do not occur between second bearing set 16 and internal tooth axle 17
When relative movement and second bearing set 16 movement, internal tooth axle 17 also follows movement；It is threaded that second bearing covers 16 outer end side surfaces
There is the second adjusting nut 25, second bearing covers 16 outer end top surfaces and is provided with the second fixing threaded hole；The outside of the vertical endoporus of cover 14 sets
Put bearing cap 15, after bolt-through bearing cap 15 and the second adjusting nut 25, cover the second fixing threaded hole of 16 outer ends with second bearing
Threaded so that the second adjusting nut 25 to be fixed on cover 14.
Further, second bearing set 16 with internal tooth axle 17 be relatively fixed couple particular by：Internal tooth axle 17 and
It is provided with the symmetrically arranged taper roll bearing of a pair being sleeved on internal tooth axle 17 21, this taper roller axle between two bearing holder (housing, cover)s 16
Hold 21 external diameter and second bearing cover 16 internal diameters equal, the internal diameter of taper roll bearing 21 is equal with internal tooth axle 17 external diameter, second
The inwall of the bearing holder (housing, cover) 16 the inner back-up ring that extends internally out enables taper roll bearing 21 to be against inside back-up ring；Bearing cap 15 and one
To being provided with the round nut 23 being threaded on internal tooth axle 17, round nut 23 and taper roll bearing between taper roll bearing 21
Being provided with locked spacer 24 and the 3rd axle sleeve 22 between 21, locked spacer 24 and the 3rd axle sleeve 22 being locked by round nut 23 so that justifying
Taper roller bearing 21 is fixed on internal tooth axle 17.
Bevel gear 18 is arranged on internal tooth axle 17 by bonded, and ball bearing 19 is fixed on internal tooth axle by end ring 20
17 the inner；The gear of angular wheel shaft 4 the inner is engaged with the bevel gear 18 on internal tooth axle 17；Second bearing set 16 outer wall fluting,
Cover 14 be provided with extend transversely through cover 14 endoporus side wall be connected in described groove with second bearing set 16 threaded tight
Gu screw 26.
In the present invention, adjusting nut (including the first adjusting nut 8 and the second adjusting nut 25) and bearing holder (housing, cover) (include first
Bearing holder (housing, cover) 9 and second bearing set 16) between connected using fine thread, because thread pitch is little, adjusting nut rotates a circle umbrella
Gear shaft 4 or internal tooth axle 17 axial movement distance are less, can play the work of fine setting angular wheel shaft 4 or internal tooth axle 17 axial distance
With, thus can intense adjustment bevel gear pair backlash；The lead angle of fine thread is less, more conducively the self-locking of screw thread, can
Reach anti-loosening purpose between adjusting nut and bearing holder (housing, cover), thus preventing angular wheel shaft 4 or the axial float of internal tooth axle 17；Carefully
The intensity of pitch thread is also higher, and static load ability is big, can bear angular wheel shaft 4 or the power required when moving axially of internal tooth axle 17.
And, the endoporus of bearing holder (housing, cover) (including first axle bearing sleeve 9 and second bearing set 16) for ensureing installation accuracy, that is, is installed
(including body 1 lateral bore and the vertical endoporus of cover 14) can not cross ambassador's bearing holder (housing, cover) because of gap and bearing holder (housing, cover) between radially jump
Dynamic, so that axle is beated therewith, the stationarity of impact bevel gear back lash and transmission；Nor bearing is made because interference fit is excessive
Set cannot be moved axially or longitudinally it is impossible to reach the purpose of adjustment backlash；So, body 1 lateral bore or cover 14 erect
Using accurate interference fits between inward hole and bearing holder (housing, cover) outer wall, also can ensure between endoporus and the bearing holder (housing, cover) of installation bearing holder (housing, cover)
There is higher centering precision, beneficial to the adjustment of backlash.
Meanwhile, for ensureing, when adjusting bevel gear pair backlash, to prevent bearing holder (housing, cover) movement in the axial direction, on the one hand
By the way of slotting on bearing holder (housing, cover), the inner hole wall installing bearing holder (housing, cover) (9,16) is passed through to connect using trip bolt (10,26)
Will be fixing with body 1 or cover 14 for bearing holder (housing, cover) in bearing grooving；On the other hand using bolt, end cap 7 (or bearing cap 15) will
Nut is fixed on body 1 or cover 14.
A pair symmetrically arranged taper roll bearing (2,21) is adopted to carry out determining on above-mentioned angular wheel shaft 4 or internal tooth axle 17
Position, the other end is 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 be connected in body 1 lateral bore with angular wheel shaft 4, and it is located in the vertical endoporus of cover 14
The vertical guiding mechanism being connected with internal tooth axle 17；Wherein when described backlash is excessive, adjusting vertical guiding mechanism makes internal tooth
Move to reduce backlash on axle 17；When described backlash is too small, adjusting horizontal adjusting mechanism makes angular wheel shaft 4 to body
1 lateral bore outer end movement is to increase backlash.
Specifically, when described backlash is excessive, turn the second adjusting nut 25, by 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；Because round nut 23 passes through locked spacer 24
With the 3rd axle sleeve 22 grade, taper roll bearing 21 is fixed on internal tooth axle 17, and makes between internal tooth axle 17 and second bearing set 16
It is relatively fixed connection, so the movement of second bearing set 16 just drives the movement of internal tooth axle 17；Turn the second adjusting nut 25, make
Obtain and move on internal tooth axle 17, reach the purpose reducing backlash；
When described backlash is too small, turn the first adjusting nut 8, by the first adjusting nut 8 and first axle bearing sleeve 9
Between fine thread drive first axle bearing sleeve 9 be axially moveable；Because 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,
Make angular wheel shaft 4 mobile to left end (outer end of body 1 lateral bore), reach the purpose increasing backlash.
The above is only the preferred embodiment of the present invention it is noted that ordinary skill people for the art
