Description
Technical field
The utility model relates to a kind of new gear.
Background technique
Gear is mechanical part common during people live, by intermeshing transmission, existing gear mainly comprises circular gear body, be provided with axis hole at gear body center, in the gabarit of gear body, be provided with gear ring, because the part between axis hole and gear ring is solid construction, therefore the weight of gear is larger, materials are also more, cost is higher, installing, comparatively inconvenience in transportation process, especially the gear of some large models, installation and transportation are required great effort especially, moreover, in forging process, also increased burden to forging equipment, and after long-term work is used, gear tends to damaged, as spot corrosion, gummed, wearing and tearing, broken teeth etc., at this time just needing to change the bad gear of point runs well to ensure machine, and traditional integral gear need to disassemble axle, again by gear shaft to dismounting, inevitably just a large amount of associated components need to be disassembled simultaneously, this dismounting and the process re-assemblying extremely bother, the replacing time is longer, simultaneously for the infringement and the replacing that reduce gear need one can slow down gear wear as far as possible, increases the structure of gear life.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of convenient disassembly, and assembling is simple, rational in infrastructure, and can reduce the damage of gear and alleviate the new gear of gear weight.
For addressing the above problem, the utility model adopts following technological scheme:
A kind of new gear, comprise external gear, middle gear and internal gear, described external gear, middle gear and internal gear set gradually from outside to inside, described external gear, on middle gear and internal gear across there being a draw-in groove outward, described draw-in groove both sides are provided with latch groove, be convenient to take out the card article in draw-in groove, described latch groove is positioned on middle gear, in described draw-in groove, hold card article, card article matches with draw-in groove and facilitates the dismounting of gear, one end of described card article is fixedly connected with the outside of internal gear, the other end is flexibly connected with the inner side of external gear, on described middle gear, have more than one openwork hole, openwork hole can alleviate gear weight, on described internal gear, also have more than one oilhole, oilhole can refuel and be lubricated, reduce gear loss.
As preferably, described openwork hole is provided with four, and weight loss effect is better.
As preferably, described four openwork holes, taking the axle center of middle gear as basic point is uniformly distributed on middle gear, on average arrange, and balance is strong.
As preferably, described oilhole is connected with oil duct, for oil transportation.
As preferably, described oilhole is provided with filter screen, for filtering.
The beneficial effects of the utility model are: owing to being provided with draw-in groove, can be by the card article simple and fast that holds in draw-in groove gear be separated, thus avoid a large amount of associated components to dismantle simultaneously, save the activity duration, owing to being provided with more than one openwork hole, can alleviate the weight of gear, and can not have influence on the running of gear, owing to being provided with more than one oilhole, can coordinate with corresponding oil duct and filter screen, carry out fueling operation, thereby slow down the wearing and tearing of gear, increase gear life.
Brief description of the drawings
Fig. 1 is the planimetric map of a kind of new gear of the utility model.
Embodiment
Consult shown in Fig. 1, a kind of new gear, comprise external gear 1, middle gear 2 and internal gear 3, described external gear 1, middle gear 2 and internal gear 3 set gradually from outside to inside, described external gear 1, on middle gear 2 and internal gear 3 across there being a draw-in groove 4 outward, draw-in groove 4 is specially a vertical bar shaped, described draw-in groove 4 both sides are provided with latch groove 5, it is one inverted trapezoidal that latch groove 5 is specially, described latch groove 5 is positioned on middle gear 2, in described draw-in groove 4, hold card article (not shown), card article is shaped as the vertical bar shape corresponding with draw-in groove 4, one end of described card article is fixedly connected with the outside of internal gear 3, the other end is flexibly connected with the inner side of external gear 1, on described middle gear 2, have more than one openwork hole 6, openwork hole 6 is circular setting, but also can be square other shapes such as grade, on described internal gear 3, also have more than one oilhole 7, oilhole 7 is uniformly distributed on internal gear 3.
Described openwork hole 6 is provided with four, also can according to circumstances adjust.
Described four openwork holes 6 are taking the axle center of middle gear 2 as basic point is uniformly distributed on middle gear 2, and physical arrangement is reasonable, can not exert an influence to gear running.
Described oilhole 7 is connected with oil duct (not shown), coordinates filter screen to carry out oiling operation.
Described oilhole 7 is provided with filter screen (not shown), coordinates oil duct to carry out oiling operation.
In use, corresponding lubricant oil is injected in oilhole 7 by oil duct and filter screen, operate, need to change if any gear, only finger nail need be snapped in to latch groove 5 card article is extracted out, and corresponding parts pull-out is dismantled.
The beneficial effects of the utility model are: owing to being provided with draw-in groove, can be by the card article simple and fast that holds in draw-in groove gear be separated, thus avoid a large amount of associated components to dismantle simultaneously, save the activity duration, owing to being provided with more than one openwork hole, can alleviate the weight of gear, and can not have influence on the running of gear, owing to being provided with more than one oilhole, can coordinate with corresponding oil duct and filter screen, carry out fueling operation, thereby slow down the wearing and tearing of gear, increase gear life.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement all should be encompassed in the new protection domain of this practicality and be as the criterion.
