Abstract
The utility model relates to the technical field of mechanical transmission parts, in particular to a combined type engine gear. The combined type engine gear comprises a gear body of a hollow structure, an annular gear ring which is formed by arranging acuminate saw teeth and trapezoid saw teeth at intervals at the outer edge of the gear body, and an upper fan-shaped open hole, a lower fan-shaped open hole, a left fan-shaped open hole and a right fan-shaped open hole are symmetrically formed in the middle of the annular gear ring through a cross-shaped connecting frame. According to the combined type engine gear, through combination of the acuminate saw teeth and the trapezoid saw teeth, abrasion can be reduced, the service life is long, transmission is more flexible, rust can be effectively prevented and the use effect is good.
Description
Technical field
The utility model relates to mechanical transmission component technical field, especially a kind of combined engine gear.
Background technique
Gear is mechanical part common during people live, and by intermeshing transmission, existing gear mainly comprises circular gear body, at gear body center, is provided with axis hole, in the gabarit of gear body, is provided with gear ring.Common gear shape is more single, and easily wearing and tearing, and working life is short, can not meet many-sided demand, and get rusty easily.
Model utility content
The technical problems to be solved in the utility model is: for overcoming the problem of above-mentioned existence, provide a kind of long service life, the combined engine gear that is difficult for getting rusty.
The utility model solves the technological scheme that its technical problem adopts: a kind of combined engine gear, the gear mass that comprises hollow structure, described gear mass outer is provided with the annular tooth ring that adopts pointed sawtooth and trapezoidal sawtooth to form separately, in the middle of described annular tooth ring, by cross link press span, is divided into four equal symmetrical weld access holes up and down.
Further, described gear mass surface is coated with rust preventive oil, can not only play good rust-proof effect, also can keep certain greasy property, wear prevention and scratch simultaneously.
The beneficial effects of the utility model are, combined engine gear of the present utility model adopts pointed sawtooth and trapezoidal sawtooth to combine, and can reduce wearing and tearing, and the life-span is long, and transmission is more flexible, and can be effectively antirust, and using effect is good.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. gear masses in figure, 2. pointed sawtooth, 3. trapezoidal sawtooth, 4. cross link press span.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
Combined engine gear as shown in Figure 1, the gear mass 1 that comprises hollow structure, gear mass 1 outer is provided with the annular tooth ring that adopts pointed sawtooth 2 and trapezoidal sawtooth 3 to form separately, in the middle of annular tooth ring, by cross link press span 4, is divided into four equal symmetrical weld access holes up and down.Gear mass 1 surface is coated with rust preventive oil, can not only play good rust-proof effect, also can keep certain greasy property, wear prevention and scratch simultaneously.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this model utility technological thought, carry out various change and modification completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to claim scope.
