Abstract
The utility model relates to the technical field of mechanical driving parts, in particular to an anti-rusting gear with positioning holes. The anti-rusting gear comprises a gear body. An annular gear ring formed by a plurality of trapezoidal saw teeth is arranged on the outer periphery of the gear body. A shaft hole is formed in the center of the gear body. Six arc-shaped notches which are uniformly distributed are formed inwards in the inner ring of the shaft hole. The plurality of positioning holes which are annularly distributed are formed between the shaft hole and the annular gear ring. The anti-rusting gear with the positioning holes, provided by the utility model, has the advantages that the wear can be reduced, the service life is long, the driving flexibility is higher, the goal of effective anti-rusting can be realized, and the using effect is good.
Description
Technical field
The utility model relates to mechanical transmission component technical field, especially a kind of antirust gear with positioning hole.
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 antirust gear with positioning hole that is difficult for getting rusty.
The utility model solves the technological scheme that its technical problem adopts: a kind of antirust gear with positioning hole, comprise gear mass, described gear mass outer is provided with the annular tooth ring that a plurality of trapezoidal sawtooth form, described gear mass central position offers axis hole, described axis hole inner ring inwardly offers six equally distributed arc-shaped notch, offers the positioning hole of a plurality of annular spread between described axis hole and annular tooth ring.
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, the antirust gear with positioning hole of the present utility model 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. trapezoidal sawtooth, 3. axis hole, 4. arc-shaped notch, 5. positioning hole.
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.
The antirust gear with positioning hole as shown in Figure 1, comprise gear mass 1, gear mass 1 outer is provided with the annular tooth ring that a plurality of trapezoidal sawtooth form, gear mass 1 central position offers axis hole 3, axis hole 3 inner rings inwardly offer six equally distributed arc-shaped notch 4, offer the positioning hole 5 of a plurality of annular spread between axis hole 3 and annular tooth ring.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.
