Abstract
The utility model discloses a split type gear which comprises a gear body, wherein an external gear and two internal gears are arranged on the gear body, grooves matched with the internal gears are arranged on the external gear, the internal gears are arranged in the grooves, the external gear is coaxially connected with the internal gears, the external gear is connected with the internal gears through screw rods, and a plurality of oil holes are arranged in the surfaces of the external gear and the internal gears. Through the way, the split type gear can improve the stability of the whole structure, avoid damaging the gears, realize a wide range of applications, reduce the production cost and prolong the service life.
Description
Technical field
The utility model relates to the gear product technical field, particularly relates to a kind of detachable gear wheel.
Background technique
Gear is widely used in as a kind of transmission part of maturation in the middle of the transmission system of various machinery, and its structural type of gear of adopting of people is generally integrated type at present, and it has easy processing, the characteristics that precision is high.But, in the time of integral gear can't being adopted, just need to adopt detachable gear wheel in the reason of some special transmission occasions because of the restriction and the transmission requirement of installing space.When current people adopt detachable gear wheel, because spatial limitation generally can't utilize the firm end face of gear wheel to carry out the moment of torsion transmission; And adopt through flat key and axle be connected to come transmitting torque, but because the mounting hole of gear cooperates the employing Spielpassung with the outer surface of transmission shaft, the existence of gear mounting hole does not contact or the little phenomenon of area of contact with the transmission shaft outer surface; And area of contact can not be controlled; So cause gear to be in " suspension " state basically, cause the integral rigidity of gear relatively poor, phenomenon that easy appearance " beating tooth ", rapid wear and flat key " roll key "; Even this has caused existing the restriction of structure or installing space; Also seldom adopt the situation of detachable gear wheel structure, and adopt other baroque design proposals to replace, make cost increase greatly.
The model utility content
The technical problem that the utility model mainly solves provides a kind of detachable gear wheel, can improve the integrally-built stability of detachable gear wheel, avoids gear to damage, and using scope is wide, reduces production costs, and increases the service life.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of detachable gear wheel is provided, comprises gear mass; Said gear mass is provided with external gear and two internal gears; Said external gear is provided with the groove that matches with internal gear, and said internal gear is arranged on inside grooves, and said external gear is connected with internal gear is coaxial; Said external gear is connected through screw rod with internal gear, and said external gear and internal gear surface are provided with a plurality of oilholes.
In preferred embodiment of the utility model, said oilhole is provided with filter screen.
In preferred embodiment of the utility model, said external gear and internal gear surface coverage have nickeling layer.
In preferred embodiment of the utility model, said internal gear thickness is less than the thickness of groove.
In preferred embodiment of the utility model, said groove cross section is circular.
The beneficial effect of the utility model is: the utility model detachable gear wheel overall structure is stable, and using scope is wide, becomes the product cost low, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model detachable gear wheel one preferred embodiment;
Fig. 2 is the left sectional view of detachable gear wheel shown in Figure 1;
The mark of each parts is following in the accompanying drawing: 1, external gear, 2, internal gear, 3, screw rod, 4, groove, 5, oilhole.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1 and Fig. 2, a kind of detachable gear wheel comprises gear mass; Said gear mass is provided with external gear 1 and two internal gears 2; Said external gear 1 is provided with the groove 4 that matches with internal gear 2, and said internal gear 2 is arranged on groove 4 inside, said external gear 1 and 2 coaxial connections of internal gear; Said external gear 1 is connected through screw rod 3 with internal gear 2, and said external gear 1 is provided with a plurality of oilholes 5 with internal gear 2 surfaces.
In addition, said oilhole 5 is provided with filter screen, and lubricant oil gets into through oilhole 5, and the oil duct through inside flows on the teeth groove of external gear 1 and internal gear 2, has lubricated teeth groove, has reduced heating and wearing and tearing, makes transmission more flexible.
In addition, said external gear 1 has nickeling layer with internal gear 2 surface coverage, and nickeling layer can be antirust, greatly protected gear.
In addition, said internal gear 2 thickness are less than the thickness of groove 4.
In addition, said groove 4 cross sections are circular.
The detachable gear wheel of the utility model is through being arranged on internal gear 2 in the groove 4 of external gear 1; Utilize screw rod 3 to regulate the position of internal gear 2; Can internal gear 2 be screwed out when needing to use, can internal gear 2 unloaded or be screwed in the groove 4 of external gear 1 in the time of need not using, easy to use.
Be different from existing technology, the utility model detachable gear wheel overall structure is stable, and using scope is wide, becomes the product cost low, long service life.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
