Abstract
The invention relates to a reinforced powder metallurgy gear which comprises a gear body, a tooth blade, a bearing hole and a bushing, wherein the tooth blade is arranged on the outermost side of the gear body, and the bearing hole is arranged in the center of the gear body. The invention has simple structure and high precision, reduces the production cost and improves the utilization rate of products.
Description
Technical Field
The invention belongs to the technical field of powder metallurgy gear manufacturing, and particularly relates to a reinforced powder metallurgy gear.
Background
Powder metallurgy gears are a highly new technology product with few chips and no chips. The powder metallurgy gear is difficult to be counted separately in the whole powder metallurgy part, but the proportion of the powder metallurgy gear in automobiles and motorcycles is far greater than that of the powder metallurgy part in other fields, by weight or by the number of the parts. Therefore, as can be seen from the increase in the proportion of the automobile and motorcycle in the entire powder metallurgy part, the powder metallurgy gear is in a rapid development position in the entire powder metallurgy part. If the gear is classified according to the characteristics of the parts, the gear belongs to structural parts, and the absolute weight of the structural parts in the whole iron-based parts is far larger than that of other types of parts, namely powder metallurgy parts.
However, the utilization rate of the single powder metallurgy gear on the market at present is not maximized, and the single powder metallurgy gear only can act on one position, so that the utilization rate is not high.
Disclosure of Invention
The invention aims to solve the defects and provides a reinforced powder metallurgy gear.
In order to overcome the defects in the background art, the technical scheme adopted by the invention for solving the technical problems is as follows: the gear comprises a gear body, a tooth blade, a bearing hole and a bushing, wherein the tooth blade is arranged on the outermost side of the gear body, and the bearing hole is formed in the center of the gear body.
In a preferred embodiment of the present invention, the number of the bushings is 9, 6 bushings in the outer ring and 3 bushings in the inner ring, so as to enhance the fixation.
The invention has the beneficial effects that: the invention has high utilization rate and high precision, reduces the production cost and ensures the working reliability.
Drawings
The invention is further illustrated with reference to the following figures and examples.
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.
As shown in figure 1, the reinforced powder metallurgy gear comprises a gear body 4, a tooth blade 1, a bearing hole 3 and a bushing 2, wherein the tooth blade 1 is arranged on the outermost side of the gear body 4, and the bearing hole 3 is arranged in the center of the gear body 4.
The working principle is as follows: when the gear is placed at a required position, the number of the bushings is more than that of the traditional powder metallurgy gear, so that the fixation of the gear is enhanced.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
Claims (2)
1. A reinforced powder metallurgy gear is characterized in that: the gear comprises a gear body, a tooth blade, a bearing hole and a bushing, wherein the tooth blade is arranged on the outermost side of the gear body, and the bearing hole is formed in the center of the gear body.
2. The reinforced powder metallurgy gear according to claim 1, wherein: the number of bushings is 9.
