Abstract
The invention discloses a cast gear which comprises a gear body and a gear ring. The gear body and the gear ring are of an integrated structure. The gear ring comprises a plurality of gear teeth. A shaft hole is formed in the center of the gear body. At least three key grooves are formed in the shaft hole portion of the gear body, and the depth of the gear body is identical to the depth of the gear ring. According to the mode, the three key grooves are formed in the cast gear so that after one key groove is damaged, another key groove can be used.
Description
Technical field
The present invention relates to gear technique field, particularly relate to a kind of cast gear.
Background technique
Along with the development of each machinery industry of China, gear industry has obtained development fast as mechanical basic part industry, and industry size constantly expands, and has become industry largest in Chinese mechanical basic part.Gear is the intermeshing mechanical parts that have tooth of energy, is mainly used in transmission system.On existing gear, only have a keyway, be used for being connected with axle, after damaging appears in this keyway, even small damage also can affect the overall operation of system, the gear that just need to more renew.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of cast gear, has three keyways, after damaging appears in a keyway, can use other keyway.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of cast gear is provided, comprise: gear body and gear ring, described gear body and gear ring are integral type structure, described gear ring comprises a plurality of teeth, the center of described gear body is provided with axis hole, and the axis hole place of described gear body is provided with at least three keyways, and described gear body is identical with the thickness of described gear ring.
In a preferred embodiment of the present invention, the axis hole place of described gear body is provided with four keyways.
In a preferred embodiment of the present invention, described four keyways evenly arrange along the cylindrical of axis hole.
In a preferred embodiment of the present invention, on the outer surface of described gear ring, be provided with wearing layer.
The invention has the beneficial effects as follows: cast gear of the present invention, there are three keyways, after damaging appears in a keyway, can use other keyway.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:
Fig. 1 is the structural representation of cast gear one preferred embodiment of the present invention.
In accompanying drawing, the mark of each parts is as follows: 1, gear body, 2, gear ring, 3, axis hole, 4, keyway.
Embodiment
Below the technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Embodiment based in the present invention, those of ordinary skills, not making all other embodiments that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of cast gear, comprise: gear body 1 and gear ring 2, described gear body 1 and gear ring 2 are integral type structure, described gear ring 2 comprises a plurality of teeth, the center of described gear body 1 is provided with axis hole 3, axis hole 3 places of described gear body 1 are provided with at least three keyways 4, when damage appears in one of them keyway 4, can use other keyway.
Described gear body 1 is identical with the thickness of described gear ring 2.
Preferably, axis hole 3 places of described gear body 1 are provided with four keyways 4.
Described four keyways 4 evenly arrange along the cylindrical of axis hole 3.
On the outer surface of described gear ring 2, be provided with wearing layer, preferred, described wearing layer adopts AIN wearing layer.
Cast gear of the present invention, has three keyways, after damaging appears in a keyway, can use other keyway.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
