Abstract
The invention relates to the technical field of a gear, in particular to a noise reduction gear. The noise reduction gear comprises an integrally cast gear body; the gear body is provided with a circle of outer teeth; the outer teeth are formed by gear grinding; each outer tooth is of a ring arc inclined shape and is at an included angle of 30 to 40 degrees with the arc surface; and the outer surface of the gear body 1 is subjected to copper plating processing. According to the invention, the tooth shape, the tooth direction and the direction of a tool mark on the tooth surface are researched, gear shaving replaces gear grinding and surface processing is carried out, so that noise generated in the operating process of a gear pair is reduced; and the noise reduction gear has a simple structure and obvious effects.
Description
Technical field
The present invention relates to the gear technique field, especially a kind of Noise-reducing gear.
Background technique
Along with growing auto manufacturing technology, the requirement of car noise is very high, and domestic like product is all to adopt roll flute to guarantee precision, but still can't meet its requirement fully, and manufacturing efficiency is lower.
Summary of the invention
In order to overcome the deficiency of existing technology, the invention provides a kind of Noise-reducing gear.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Noise-reducing gear, comprise the gear body of integrally casting, and the gear body has a circle external tooth, and described external tooth forms through roll flute, and external tooth is skewed, becomes 30-40 degree angle with cambered surface.
According to another embodiment of the invention, further comprise that described this external surface of gear carries out copper plating treatment.
The invention has the beneficial effects as follows, by the research to tooth-formation of gear teeth directional and flank of tooth tool marks direction, with shaving, replace roll flute, by surface treatment, the noise while turning round to reduce gear pair, simple in structure, successful.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is plan view of the present invention;
Fig. 2 is side view of the present invention;
Fig. 3 is another embodiment's plan view;
Fig. 4 is another embodiment's side view;
In figure 1, the gear body, 2, external tooth, 11, the gear shaft part, 12, external tooth two.
Embodiment
As shown in Figure 1 and Figure 2, be structural representation of the present invention, a kind of Noise-reducing gear, comprise the gear body 1 of integrally casting, and gear body 1 has a circle external tooth 2, and described external tooth 2 forms through roll flute, and external tooth 2 is skewed, becomes 30-40 degree angle with cambered surface.The present invention replaces roll flute with shaving, obtains the most rational flank of tooth tool marks, improves the break-in efficiency between gear.In addition, the profile of tooth teeth directional is carried out to reasonable correction of the flank shape, under the prerequisite that does not reduce flank of tooth wear resistance, the area of contact of the flank of tooth while reducing gear operation, and guarantee that flank of tooth contact is at position the most reasonably.During the gear engagement, effectively reduced the noise sent in the operation process.
Described gear body 1 outer surface outer surface carries out copper plating treatment.Copper plating treatment is carried out in flank of tooth surface, improve the roughness of the flank of tooth, the frictional force while moving to reduce gear.During the gear engagement, effectively reduced the noise sent in the operation process.
As shown in Figure 3, Figure 4, another embodiment, the Noise-reducing gear axial workpiece, inside is axle shape projection, outside similar to Noise-reducing gear, has noise reduction effect.
The present invention studies by the profile modifying parameters to the tooth-formation of gear teeth directional, and replaces roll flute with shaving, obtains the tool marks direction of the rational flank of tooth, then the flank of tooth is carried out to surface treatment, by above all measures, and the noise while reducing to greatest extent the gear pair running.
Claims (2)
