Description
Technical field
The utility model technology belongs to the design field of finish forge product, particularly relates to a kind of welding and changes finish forge product structure.
Background technique
At present in gear application, component part is very common.This component part is generally all designed to press-fit welding pattern.In actual production, the process engineering of welding again after using this to press-fit, has a lot of actual problem and defect.As after press-fiting, block position precision is bad, easy at weld slag inclusion (shot and dirt) etc. after welding, the total member assembly quality of the impact that these problems are serious, even serious also may cause sealing-off, causes the usability of product and life-span to be subject to serious impact.In addition, due to be builtup member separately the independent manufacturing carry out assembly welding again, also add management difficulty to the manufacturing.Therefore, carry out redesign to the original project organization of assembly to be necessary.
For above technical problem, therefore need to make improvements.
Model utility content
For above-mentioned situation, for overcoming the defect of prior art, the purpose of this utility model is to provide a kind of processing technique adopting overall finish forge shaping, by originally forging driven tooth respectively and in conjunction with tooth, the technique press-fiting, weld is carried out again after teeth portion to be processed, change now directly finish forge assembly whole gear into, then the welding of design of processing assembly gear being carried out to teeth portion changes finish forge product structure.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of welding changes finish forge product knot
Structure, comprises gear 1, is located at driven tooth 2 in gear 1 and in conjunction with tooth 3; The cross section of described gear 1 is step-like, and this driven tooth 2 is positioned at first step 7 place of gear 1; This is positioned at second step 8 place of gear 1 in conjunction with tooth 3; The external diameter of described driven tooth 2 is greater than the external diameter in conjunction with tooth 3; Gear 1, driven tooth 2 and one-body molded in conjunction with tooth 3.
As a kind of preferred version of the present utility model, the middle part of described gear 1 forms mounting hole 4, the width of this mounting hole 4 and the width of gear 1 in the same size; Described mounting hole 4 forms installation step 6 with the right side of gear 1, and this installation step 6 is parallel with the described end face in conjunction with tooth 3.
As a kind of preferred version of the present utility model, the left side of described gear 1 is provided with multiple annular groove 5; This annular groove 5 is one-body molded with gear 1.
As a kind of preferred version of the present utility model, described annular groove 5 is 1/5 of whole gear 1 width Lz at the cup depth Lw of gear 1.
As a kind of preferred version of the present utility model, described driven tooth 2 and be made up of magnalium in conjunction with tooth 3.
The beneficial effects of the utility model: adopt said structure, have simple and reasonable, the product after finish forge processing no longer needs assembly welding, thus avoids the unfavorable factor because assembly welding brings thoroughly; Assembly complete machine installation effect is promoted significantly; Make at product in manufacturing process, significantly reduce complexity and the life cycle of the product of production management, improve the quality of product significantly, thus significantly reduce the cost of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Reference character: gear 1, driven tooth 2, in conjunction with tooth 3, mounting hole 4, annular groove 5, installation step 6, first step 7, first step 8.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is elaborated.
One welding as shown in Figure 1 changes finish forge product structure, comprises gear 1, is located at driven tooth 2 in gear 1 and in conjunction with tooth 3; The cross section of described gear 1 is step-like, and this driven tooth 2 is positioned at first step 7 place of gear 1; This is positioned at second step 8 place of gear 1 in conjunction with tooth 3; The external diameter of described driven tooth 2 is greater than the external diameter in conjunction with tooth 3; Gear 1, driven tooth 2 and one-body molded in conjunction with tooth 3.
Direct finish forge assembly whole gear, then to the driven tooth 2 of assembly gear and the design carrying out the processing of teeth portion in conjunction with tooth 3.Because the product after finish forge processing no longer needs assembly welding, thus avoids the unfavorable factor because assembly welding brings thoroughly; The precision of product is overally improved, and intensity increases, and assembly complete machine installation effect is promoted significantly.
The middle part of described gear 1 forms mounting hole 4, the width of this mounting hole 4 and the width of gear 1 in the same size; Described mounting hole 4 forms installation step 6 with the right side of gear 1, and this installation step 6 is parallel with the described end face in conjunction with tooth 3, makes gear in running, can be more steady, assembles convenient.
This left side stating gear 1 is provided with multiple annular groove 5; This annular groove 5 is one-body molded with gear 1; Annular groove 5 is 1/5 of whole gear 1 width Lz at the cup depth Lw of gear 1; The setting of this structure, not only increases surface abrasion resistance effect, and can reduce consumptive material, reduces the raw materials consumption of gear, also just reduces cost.
This driven tooth 2 and be made up of magnalium in conjunction with tooth 3, is made up of the magnalium after heat treatment process process with aluminum-magnesium alloy gear, has higher intensity.
In course of working, the first entirety of direct precision forging gear body 1, then to the driven tooth 2 be located in gear 1 and the design carrying out the processing of teeth portion in conjunction with tooth 3; Such finish forge accuracy of gear is out overally improved, and complete machine installation effect is promoted significantly, and intensity increases, can as power shift gear, be used on the gearbox of passenger car, and on the gear of the not high transmission campaign of required precision, be applicable to promote the use.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
Although more employ reference character gear 1 in figure herein, driven tooth 2, in conjunction with tooth 3, mounting hole 4, annular groove 5, installation step 6, first step 7, term such as first step 8 grade, does not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
