Description
Technical field
The utility model relates to mechanical parts technical field, has been specifically related to a kind of miniature gears.
Background technique
Miniature gears due to size less, generally can only be full of cooperation carry out installation fix, use thinner fixing rod to be worn together by miniature gears to carry when carrying, in whole handling process, due to miniature gears do not fix and collide to damage situation often occur, for this reason, solution is now that special box made of plastic is to carry miniature gears, this special box is placed respectively by each miniature gears, therefore this special box compares and takes up room, and access miniature gears trouble.
The oil hole of miniature gears is the through hole from the flank of tooth to axle center, although this through hole can make miniature gears obtain good lubrication, affect the intensity of miniature gears self, of long duration, the miniature gears on through hole side can produce tired impaired, causes miniature gears cracked time serious.
Model utility content
For solving the problems of the technologies described above, we have proposed a kind of miniature gears, its object: can not collide between miniature gears during carrying, lubricating oil filling is convenient, and does not affect the intensity of miniature gears self.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of miniature gears, the circular orientation circle comprising gear body He be made of plastics, is provided with mounting hole in the middle part of gear body, and mounting hole inwall is provided with keyway;
The side, side of described gear body is provided with the annular groove corresponding to circular orientation circle, and the opposite side side of described gear body is provided with square groove, and the side of square groove is connected with mounting hole by through hole;
The side, side of described circular orientation circle is provided with the locating column corresponding to square groove.
Preferably, the side, side of described circular orientation circle protrudes from the side, side of described gear body.
Pass through technique scheme, at the end of production, circular orientation circle is assigned in the annular groove of a miniature gears, locating column is assigned in the square groove of another miniature gears, thus miniature gears is one by one connected into an entirety, convenient in carrying, and can not collide between miniature gears during carrying; The opposite side side of gear body is provided with square groove, and the side of square groove is connected with mounting hole by through hole, and lubricating oil filling is convenient, and through hole is not from the flank of tooth to axle center, can't affect the intensity of gear body self.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the schematic front view of a kind of miniature gears disclosed in the utility model;
Fig. 2 is the generalized section in the A-A direction along Fig. 1.
Numeral and the corresponding part title represented by letter in figure:
1. gear body 11. mounting hole 12. keyway 13. annular groove 14. square groove 15. through hole 2. circular orientation circle 21. locating column.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with schematic diagram, embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of miniature gears, the circular orientation circle 2 comprising gear body 1 and be made of plastics, mounting hole 11 is provided with in the middle part of gear body 1, mounting hole 11 inwall is provided with keyway 12, this miniature gears is coordinated with axle by keyway 12, adds the rotation synchronism of this miniature gears.
The side, side of described gear body 1 is provided with the annular groove 13 corresponding to circular orientation circle 2, the opposite side side of described gear body 1 is provided with square groove 14, the side of square groove 14 is connected with mounting hole 11 by through hole 15, lubricating oil filling is convenient, and through hole 15 is not from the flank of tooth to axle center, the intensity of gear body self can't be affected, in addition this miniature gears is also provided with the plug corresponding to square groove 14, after square shaped groove 14 added lubricant oil, with plug, square groove 14 is blocked, lubricant oil in through hole 15 can be flowed out slowly, lubricant oil can lubricate for a long time, improve lubrication effect, avoid the waste of lubricant oil.
The side, side of circular orientation circle 2 is provided with the locating column 21 corresponding to square groove 14, at the end of production, circular orientation circle 2 is assigned in the annular groove 13 of a miniature gears, locating column 21 is assigned in the square groove 14 of another miniature gears, thus miniature gears is one by one connected into an entirety, convenient in carrying, and can not collide between miniature gears during carrying.
The side, side of described circular orientation circle 2 protrudes from the side, side of described gear body 1, collides when preventing carrying further between miniature gears.
Be exactly more than a kind of structural feature and action effect of miniature gears, its advantage: can not collide between miniature gears during carrying, lubricating oil filling is convenient, and does not affect the intensity of miniature gears self.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
