Abstract
The utility model provides an improved novel gear which comprises a main body. A gear, a cavity, an inner shaft and a shaft hole are arranged on the main body. A supporting strip is arranged in the cavity. Compared with the gear before improvement, the improved novel gear has the following characteristics: the production cost is greatly reduced; although the improved novel gear is light in weight, the supporting intensity is not lowered; therefore, the improved novel gear can replace the gear before improvement for mass production.
Description
Technical field
The utility model relates to a kind of gear, is specifically related to the gear that a kind of powder metallurgical technique is made.
Background technique
Gear and gear product thereof are the important foundation parts of mechanized equipment, and the main transmission part of most complete set of machines all is gear transmission.Gear transmission is a kind of mechanical transmission most widely used in the modern mechanical product.This is because it can guarantee constant velocity ratio, has advantages such as the transmission power scope is big, efficient is high, the life-span is long.Deficiency is cost of production height, manufacturing and the installation precision height of gear.
Gear is the intermeshing mechanical parts that tooth is arranged of energy, and its application in mechanical transmission and whole mechanical field is extremely extensive.And exactly can reduce production costs with the gear of powder metallurgical technique manufacturing, guarantee the morpheme of gear and the conformity of tolerance of size.With compare with the gear of manufacturings such as machining, punching press, extruding, precision casting such as diecasting, gray iron casting, forging rolling material, forging, powder metallurgical gear has a series of advantage, because the consideration on the various manufacturing factors, the application of powder metallurgical gear is subjected to some restrictions but simultaneously.
Though powder metallurgical gear is difficult to independent statistics in whole powdered metal parts, no matter be by quality or by number of spare parts, powder metallurgical gear shared ratio in automobile, motorcycle all is far longer than the powdered metal parts in the other field.Therefore, from the rising of automobile, motorcycle parts proportion whole powdered metal parts, as can be seen, powder metallurgical gear is in the status of develop rapidly in whole powder metallurgy metal parts.
Summary of the invention
The purpose of this utility model is to provide a kind of gear of powder metallurgical technique manufacturing, new gear after particularly a kind of the improvement, gear compared with before-improvement reduces production costs significantly, and is in light weight, and support strength does not reduce, and can replace improving front gear and produce in enormous quantities.
The technical solution of the utility model is, the new gear after a kind of the improvement comprises body, and described body is provided with gear, cavity, interior axle, axis hole, also is provided with supporting bar in the described cavity.
In preferred embodiment of the utility model, described body is the gear that powder metallurgical technique is made.
In preferred embodiment of the utility model, described supporting bar is six, also can for any bar number to reach required support strength.
In preferred embodiment of the utility model, on the described interior axle three axis holes are arranged, to reach the required balance degree.
In preferred embodiment of the utility model, described new gear is with to improve front gear size, thickness, the number of gears, teeth groove identical.
New gear after the improvement described in the utility model gear compared with before-improvement has following effect: reduces production costs significantly, and in light weight, and support strength does not reduce, and can replace improving front gear and produce in enormous quantities.
Description of drawings
Fig. 1 is the new gear structural drawing after the utility model improves;
Fig. 2 is the gear structure figure before the utility model improves.
Annex mark is as follows in the accompanying drawing: 1, body, 2, gear, 3, cavity, 4, interior axle, 5, axis hole, 6, supporting bar, 7, cavity, 8, interior axle, 9, axis hole.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby protection domain of the present utility model is made more explicit defining so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that.
Gear described in the utility model adopts the powder metallurgic method manufacturing, because the equipment of saving of labor, material-saving, manufacturing efficiency height, use is few, energy-conservation, the cost of production of gear significantly lowers, and its application in mechanical transmission and whole mechanical field is extremely extensive.
See also Fig. 1, Fig. 1 is the new gear structural drawing after the utility model improves, and comprises body 1, and described body 1 is provided with gear 2, cavity 3, interior axle 4, axis hole 5, also is provided with supporting bar 6 in the described cavity.Described supporting bar is six, also can for any bar number to reach required support strength; On the axle three axis holes 5 are arranged in described, to reach the required balance degree.
Fig. 2 is the gear structure figure before the utility model improves, and axis hole 9 is two, and the 3rd the new gear after cavity 7 and interior axle 8 improve is also different for what seal, and it is heavier to improve front gear weight comparatively speaking, and cost is also high.Described new gear reduces production costs significantly with to improve front gear size, thickness, the number of gears, teeth groove identical, and is in light weight, and support strength does not reduce, and can replace improving front gear and produce in enormous quantities.
The above; it only is embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
