Abstract
A kind of high-precision built-up gear axis belongs to reduction box technical field, effective gear position, hobboing cutter arc position is included on gear shaft, it is characterised in that the hobboing cutter arc position position is equipped with bearing interstage sleeve, and bearing rib is equipped on bearing interstage sleeve and gear shaft；This patent utilizes hobboing cutter arc position installation bearing interstage sleeve structure bearing rib, gear shaft length can effectively be shortened, improve gear shaft run stability, so as to improve reduction box operating accuracy, shorten reduction box length, reduction material cost, the application field of reduction box is expanded, robot, high ferro station automatic ticket inspection wicket, logistics delivery machine sorting system etc. is can be widely applied to and requires reduction box precision height, small occasion.
Description
Technical field
The utility model belongs to reduction box technical field, and in particular to a kind of high-precision built-up gear axis.
Background technology
Conventional gear axis is generally machined with gear, bearing rib, and gear is substantially molded using Vehicle Processing, machine-shaping position packet
Effective gear position and hobboing cutter arc position are included, that is, certainly exists one section of Gear Processing between effective gear section and bearing rib and draws
The hobboing cutter arc position risen, for this section of hobboing cutter arc position generally in 15 ~ 20mm, existing makes the axial length of gear shaft need increase by one
The length of a hobboing cutter arc position, and the increase of gear shaft length can cause to operate instability increasing, reduce gear-box precision, simultaneously
Also gear-box axial length is caused to increase, material cost is both increased, and be restricted in terms of field is used because long, such as machine
The these requirements reduction box precision such as people, high ferro station automatic ticket inspection wicket, logistics delivery machine sorting system are high, small application field
Good application effect can not all be obtained.
Utility model content
The utility model is intended to provide a kind of high-precision built-up gear axis technical solution, efficiently uses the rolling of gear installation position
Knife arc position overcomes problems of the prior art to shorten gear shaft length.
A kind of high-precision built-up gear axis exists comprising effective gear position, hobboing cutter arc position, feature on gear shaft
Bearing interstage sleeve is equipped in the hobboing cutter arc position position, bearing rib is equipped on bearing interstage sleeve and gear shaft.
A kind of high-precision built-up gear axis, it is characterised in that the bearing interstage sleeve is socketed in hobboing cutter arc position
On, bearing interstage sleeve is interference fitted with hobboing cutter arc position.
A kind of high-precision built-up gear axis, it is characterised in that set on the gear shaft similary with bearing interstage sleeve
The baffle ring of height, bearing interstage sleeve contact cooperation with baffle ring and collectively form bearing rib.
A kind of above-mentioned high-precision built-up gear axis, it is novel, rational in infrastructure, bearing rib is installed using hobboing cutter arc position
Set structure bearing rib, can effectively shorten gear shaft length, improve gear shaft run stability, so as to improve reduction box work essence
Degree shortens reduction box length, reduces material cost, expands the application field of reduction box, can be widely applied to robot, high ferro
Stand automatic ticket inspection wicket, logistics delivery machine sorting system etc. requires that reduction box precision is high, small occasion.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
In figure：1- effective gears position, 2- hobboing cutters arc position, 3- bearings interstage sleeve, 4- bearing ribs, 5- baffle rings, 6- gear shafts.
Specific embodiment
In conjunction with Figure of description, specific embodiment of the present utility model is described in detail：
Fig. 1 show a kind of high-precision built-up gear axis, and effective gear position 1, hobboing cutter arc position 2, rolling are included on gear shaft 6
Socket setting bearing interstage sleeve 3 on knife arc position 2, on gear shaft 6 the adjacent setting of bearing interstage sleeve 3 and bearing interstage sleeve 3 with high gear,
Setting and the baffle ring 5 of 3 similary height of bearing interstage sleeve, bearing interstage sleeve 3 contact cooperation with baffle ring 5 and collectively form bearing on gear shaft 6
Gear 4.
In above-described embodiment, the thickness of bearing interstage sleeve 3 is usually no more than 2mm, and the width of bearing interstage sleeve 3 is generally less than bearing
The width of gear 4 when the width of bearing interstage sleeve 3 can meet the width of bearing rib 4, no longer needs to set baffle ring 5 on gear shaft 6,
A kind of this implementation special case of application as this programme, is also included in embodiment.
During using this programme, processing method is essentially：
1）Gear is processed according to the technique of full depth tooth wheel shaft, is processed in backgear axle 6 comprising effective gear position 1, hobboing cutter
Arc position 2, tip diameter D can suitably take plus tolerance；
2）Process bearing interstage sleeve 3, the outer diameter of bearing interstage sleeve 3 puts bearing rib 4 and grinds allowance, hole machined in bearing interstage sleeve 3
When internal diameter D1 take appropriate negative common difference；
3）Gear shaft 6 is interference fitted with bearing interstage sleeve 3, and bearing interstage sleeve 3 is socketed in hobboing cutter arc position 2；
4）Mill processing baffle ring 5 on gear shaft 6, mill is worked into outer diameter to bearing interstage sleeve 3 simultaneously and baffle ring 5 is consistent, baffle ring 5 and axis
It holds interstage sleeve 3 and collectively forms bearing rib 4.
Using above-described embodiment, using Gear Processing be molded present in the setting installation bearing of hobboing cutter arc position 2 interstage sleeve 3 use
In structure bearing rib 4, length about 15 ~ 20mm of hobboing cutter arc position 2, therefore it can effectively shorten gear shaft length, improve gear shaft
Run stability, so as to improve reduction box operating accuracy, shorten reduction box length, reduction material cost.
