Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
Be a specific embodiment of the present utility model as Figure 1-5, this is used for the detachable hobbing device of roller picker, comprise the roller bearing 2 being arranged on roller picker support two ends by bearing block 1, be connected to the split type gear hobbing 3 on roller bearing 2 in turn, also comprise the long fixed cover 8 and short fixed cover 9 that are separately positioned on roller bearing 2 two ends, be arranged on the separation sleeve 4 between adjacent split type gear hobbing 3, the stop device of fixed cover axially-movable is prevented respectively in the arranged outside of length fixed cover, the inner side of length fixed cover is laminated respectively with outside the end of split type gear hobbing 3, be laminated respectively with outside the end of split type gear hobbing 3 inside the two ends of described separation sleeve 4, described length fixed cover is interconnected by pin key with roller bearing 2 respectively,
Described split type gear hobbing 3 is made up of symmetrical roll left tooth and right gear hobbing, and left and right gear hobbing arranges the pin key hole 5 be connected with roller bearing 2 respectively, and described split type gear hobbing 3 is uniform depressed part 6 and lug boss 7 along excircle direction.
When needing to change the gear hobbing damaged, first dismantle the stop device of long fixed cover end, ensure the fixed cover on roller bearing, gear hobbing, separation sleeve can easily movement on roller bearing, during practical operation, only long fixed cover 8 is moved a segment distance toward the end direction of roller bearing 2, long fixed cover 8 is not required to disassemble from roller bearing 2, split type gear hobbing 3 and separation sleeve 4 end direction toward roller bearing 2 moves by axial direction then along roller bearing 2 successively one by one, till moving to the required gear hobbing changed, the pressing with the tip inside of its both sides separation sleeve 4 is departed from respectively by outside the end of left and right gear hobbing, by pin key hole 5 new left and right gear hobbing positioned with roller bearing 2 respectively and be connected and again carry out pressing by outside gear hobbing end, left and right with the tip inside of the separation sleeve 4 of both sides, and then along roller bearing 2, position recovering is carried out in remaining split type gear hobbing 3 and separation sleeve.More than describe and belong to the nearer situation of the gear hobbing distance fixed cover of replacing, if the gear hobbing damaged more closely only can dismantle short fixed cover end-stop devices apart from short fixed cover, described replacing options with describe above identical.
In this example, described stop device comprises the one group of middle round nut 10 with stop washer 13 being separately positioned near outside length fixed cover and being arranged on roller bearing 2, and stop washer and round nut all belong to standard component.
In this example, the detachable hobbing device horizontal positioned respectively of roller picker is used for described in overlapping at least two, the roller bearing axis of adjacent two covers is parallel to each other and the adjacent two split type gear hobbings 3 of overlapping on roller bearings 2 are crisscross arranged, form sieve aperture between split type gear hobbing 3 and separation sleeve 4, respectively sprocket wheel 11 is set in the end of the roller bearing 2 often overlapping this device.
In this example, described fixed sleeves 8 adopts split-type structural and is divided into left outside fixed cover and right outside fixed cover, and described left and right fixed sleeves is respectively arranged with the pin shaft hole be connected with roller bearing 2, and described left and right fixed sleeves arranges interconnective bolt hole 12 respectively.
Technique effect of the present utility model is:
1. owing to devising split type gear hobbing 3 and detachable apparatus, split type gear hobbing 3 and being interconnected between roller bearing 2 and separation sleeve 4 is removed by detachable apparatus, when changing, gear hobbing and separation sleeve are removed from roller bearing no longer one by one, Renewal process is time saving and energy saving.
2., owing to devising split type gear hobbing 3, when changing, part gear hobbing can be changed, gear hobbing entirety need not be changed, having saved use cost.
3. owing to devising split type gear hobbing 3 and detachable apparatus, when changing, because remaining gear hobbing and separation sleeve can not depart from gear hobbing all the time, therefore avoid all the other gear hobbings and separation sleeve reduction wrong, thus indirectly improve the result of use of this device, extend the service life of this device further, reduce further use cost.
4. owing to devising the symmetrical left and right two parts gear hobbing of split type gear hobbing 3, two parts gear hobbing highly versatile, simultaneously easy for removal and installation, rational in infrastructure and compact.
5. adopt split-type structural owing to devising fixed sleeves 8, split-type structural is convenient to dismounting more, is convenient to safeguard.
6., owing to devising one group of middle round nut 10 with stop washer 13, means of retention is simple and reliable, effectively prevent moving axially of fixed cover.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
