Abstract
The utility model relates to the technical field of mechanical transmission parts, in particular to a gear with a positioning hole. The gear comprises a gear body, wherein a shaft hole is formed in the center of the gear body; a gear ring formed by a plurality of sawteeth is arranged at the outer edge of the gear body; an annular groove which is inwards concave is formed between the shaft hole and the gear ring; a plurality of positioning holes are uniformly distributed in the annular groove; anti-rust oil is coated on the surface of the gear body. The gear with the positioning hole is capable of reducing wear and effectively preventing rust, frosting and scratch, long in service life, more flexible in transmission, and good in using effect.
Description
Technical field
The utility model relates to mechanical transmission component technical field, especially a kind of 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 easily weares and teares, 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 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 gear with positioning hole, comprise gear mass, described gear mass center is provided with axis hole, described gear mass outer is provided with the gear ring that a plurality of sawtooth form, between described axis hole and gear ring, offer the annular groove caving inward, on described annular groove, be evenly distributed with a plurality of positioning holes, 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.
Further, described sawtooth and gear ring outer rim are 30 °～45 °.
The beneficial effects of the utility model are, the 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, prevents frosted and scratch, 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. axis hole, 3. sawtooth, 4. 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 gear with positioning hole as shown in Figure 1, comprise gear mass 1, gear mass 1 center is provided with axis hole 2, gear mass 1 outer is provided with the gear ring that a plurality of sawtooth 3 form, and offers the annular groove caving inward between axis hole 2 and gear ring, is evenly distributed with a plurality of positioning holes 4 on annular groove, 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.Sawtooth 3 is 30 °～45 ° with gear ring outer rim.
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.
