The technical solution of the utility model is as follows：
A kind of internal gear, including gear, the inner surface of the gear are provided with teeth, the two neighboring teeth
Between be provided with teeth groove, be provided with the side wall of the gear at oil groove, the position of oil groove correspondence teeth groove and be equipped with one
Individual fuel feed hole, is equipped with three oil outlets in the teeth groove of correspondence oil-feed hole site, three oil outlets with it is corresponding
The fuel feed hole connection insertion of position；Pressing plate is embedded with the oil groove, in the pressing plate provided with six through holes.
Using above structure, it is designed with gear at the position of each teeth groove of correspondence in fuel feed hole, each teeth groove also
Provided with three oil outlets, fuel feed hole and three oil outlets all connect insertion, increase fuel-displaced area, increase the lubrication of teeth
Each teeth, in the case where rotating speed is not high, can also be realized the purpose of self-lubricating without centrifugal force, can accelerated to gear by area
Body cools, it is ensured that the stability of rotation of gear, extends service life；The pressing plate being embedded is easy to dismounting, retracts after pressing plate,
Cleaning treatment can be carried out to positions such as fuel feed hole, oil grooves, reduce use cost, load onto pressing plate when in use, moreover it is possible to hinder
Keep off impurity and block fuel feed hole, it is simple in construction, cost is reduced, service life is extended, it is applied widely.
For the ease of circulating for lubricating oil, while being easy to dismount pressing plate, preferably, the oil groove is interior narrow outer width
Ledge structure, the width of the pressing plate is adapted with the notch of oil groove, the pressing plate tight fit is embedded in oil groove, and pressing plate
Medial surface is abutted with the step surface of oil groove, and the lateral surface of pressing plate is flushed with the lateral surface of gear.
In order to increase fuel-displaced area, preferably, being inner small and outside big horn-like structure at the aperture of the oil outlet.
In order to reduce the influence of centrifugal force, increase lubrication area, preferably, the both sides of the teeth end of engagement are circle
Corner structure.
For the ease of being easy to the flowing to lubricating oil to be oriented to, preferably, provided with connection between six through holes
Groove, the link slot is located on the lateral surface of gear.
Beneficial effect：The utility model sets oil groove and fuel feed hole in gear, and sets in teeth groove oil outlet,
Oil groove also is covered with pressing plate, it is simple in construction, the lubrication area of teeth is increased, service life is improved, reduces cost, is applicable
Scope is wide.
Brief description of the drawings
Fig. 1 is the structural representation of gear.
Fig. 2 is the structural representation of pressing plate.
Fig. 3 is assembling structure schematic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Fig. 1, Fig. 2 and Fig. 3, the utility model is made up of gear 1 etc., the inner surface of the gear 1
Provided with teeth 11, the both sides of the end of engagement of teeth 11 are fillet structure, and teeth groove is provided between the two neighboring teeth 11,
Tight fit in oil groove 21, the oil groove 21 is provided with the side wall of the gear 1 and is embedded with pressing plate 3, the oil groove 21 is interior
The ledge structure of narrow outer width, the width of the pressing plate 3 is adapted with the notch of oil groove 21, and the medial surface and oil groove 21 of pressing plate 3
Step surface abut, the lateral surface of pressing plate 3 flushes with the lateral surface of gear 1.
A fuel feed hole 22 is equipped with the position of the correspondence of oil groove 21 teeth groove, described in correspondence fuel feed hole 22 position
Three oil outlets 23 are equipped with teeth groove, three oil outlets 23 are connected insertion with the fuel feed hole 22 of correspondence position；It is described
It is inner small and outside big horn-like structure at the aperture of oil outlet 23.
Provided with six through holes on the pressing plate 3, link slot 31, the link slot 31 are provided between six through holes
In on the lateral surface of gear 1.
Application method of the present utility model is as follows：
As shown in Fig. 1 to Fig. 3, fuel feed hole 22, each teeth groove are designed with the position of each teeth groove of correspondence in gear 1
Three oil outlets 23 are inside additionally provided with, fuel feed hole 22 and three oil outlets 23 all connect insertion, and the horn-like aperture of oil outlet 23 makes
Show that pasta product is increased, increase the lubrication area of teeth 11, the fillet structure of teeth position of engagement both sides can reduce lubrication
Oil flies the effect spilt under the action of the centrifugal force, improves the effect of teeth self-lubricating, in the case that rotating speed is not high, does not borrow
