Abstract
The utility model relates to a timing gear pulley of a powder metallurgy engine camshaft used for an automobile, which comprises a gear pulley body, wherein an installation hole, a bearing hole, a weight reduction hole and peripheral outer teeth are arranged on the gear pulley body. The utility model is characterized in that a groove is arranged on the upper surface of the gear pulley body near the tooth ring of the outer teeth, signal iron is welded in the groove through sintering welding, and the signal iron and the gear pulley body form an integral structure. Thereby, the method for adding the signal iron through the sintering welding has the advantages of simple operation, high production efficiency and good consistency of products, the working procedure of manual welding is avoided, the processing process is reduced, the dynamic balance of the products is improved, and the stability is higher.
Description
Technical field
The utility model belongs to powder metallurgical technology, particularly relates to a kind of automobile powder metallurgy engine cam timing toothed belt wheel.
Background technique
At present, existing automobile is generally a toothed belt wheel with powder metallurgy engine cam timing toothed belt wheel, in order to send the signal of toothed belt wheel transmission situation, fixedly mounts a signal iron usually before use on the cingulum wheel body.Because processing conditions restriction, that existing signal iron can produce in use is insecure, measure problems such as inaccurate.Because the existing inconsistency that causes by artificial installation signal iron also can have influence on toothed belt wheel dynamically balanced instability in operation process, and then influence the quality of manufacturing efficiency and motor.
Summary of the invention
The utility model provides a kind of a kind of automobile powder metallurgy engine cam timing toothed belt wheel firm in structure, that improve the quality of products for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of automobile powder metallurgy engine cam timing toothed belt wheel, comprise the cingulum wheel body, on the cingulum wheel body, have the external tooth of mounting hole, bearing hole, lightening hole, periphery, it is characterized in that: the toothed ring gear place is provided with a groove outside described cingulum wheel body upper surface is approaching, by signal iron of sintering weldering welding, signal iron and cingulum wheel body become one structure in groove.
Advantage and the good effect that the utlity model has are: because the utility model is adopting technique scheme, the toothed ring gear place is provided with a groove outside described cingulum wheel body upper surface is approaching, by signal iron of sintering weldering welding, signal iron and cingulum wheel body are structure as a whole in groove.So the method that adopts sintering weldering increase signal iron is simple to operate, manufacturing efficiency is high, and consistency of product is good, has saved the operation of manual welding, has reduced course of working, and the dynamic balancing that improves product is more stable.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A-A sectional view among Fig. 1;
Fig. 3 is the utility model perspective view.
Among the figure: 1, toothed belt wheel main body; 1-1, groove; 2, mounting hole; 3, bearing hole, 4, lightening hole; 5, external tooth; 6, signal iron.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Embodiment:
See also Fig. 1 to Fig. 3, a kind of automobile powder metallurgy engine cam timing toothed belt wheel, comprise cingulum wheel body 1, on cingulum wheel body 1, have the external tooth 5 of mounting hole 2, bearing hole 3, lightening hole 4, periphery, it is characterized in that: the toothed ring gear place is provided with a groove 1-1 outside described cingulum wheel body upper surface is approaching, by signal iron 6 of sintering weldering welding, signal iron 6 becomes one structure with cingulum wheel body 1 in groove.So the method that adopts sintering weldering increase signal iron is simple to operate, manufacturing efficiency is high, and consistency of product is good, has saved the operation of manual welding, has reduced course of working, and the dynamic balancing that improves product is more stable.
