Abstract
The invention discloses a novel low-noise gear which comprises a gear, a lubricating thin film and a noise absorbing layer. The gear comprises a gear body and gear teeth, multiple ventilating holes are arranged on the gear body, the noise absorbing layer comprises a first noise absorbing plate and a second noise absorbing plate, the lubricating thin film is arranged on the gear teeth, the first noise absorbing plate is arranged on the left side of the gear body, and the second noise absorbing plate is arranged on the right side of the gear body. By the above mode, the novel low-noise gear can absorb noise generated during working of the gear as much as possible.
Description
Technical field
The present invention relates to a kind of new gear, particularly related to a kind of low-noise gear.
Background technique
Gear is to have tooth can mesh continuously the mechanical component that transmits motion and power on wheel rim, is also can the intermeshing mechanical parts that tooth is arranged.
During the gear engagement, owing to inevitably existing tooth pitch, profile of tooth equal error, can produce mesh impact and the noise corresponding with gear mesh frequency occurs in operation process, due to relative sliding, frictional noise occur also between the flank of tooth, so people need to satisfy the gear of people's demand more.
Summary of the invention
The present invention is mainly the requirement for present market, and a kind of have diverse in function, low-noise gear that noise is little are provided.
To achieve these goals, the invention provides following technological scheme:
The invention provides a kind of low-noise gear, it comprises gear, composite lubricating film and absorbent treatment, described gear comprises gear body and the gear teeth, be provided with a plurality of vents on described gear body, described absorbent treatment comprises the first acoustic board and the second acoustic board, described composite lubricating film is arranged on the described gear teeth, and described the first acoustic board is arranged at the left side of described gear body, and described the second acoustic board is arranged at the right side of described gear body.
In a preferred embodiment of the present invention, described composite lubricating film is pasted on the described gear teeth.
In a preferred embodiment of the present invention, the spacing between adjacent two described vents is identical.
In a preferred embodiment of the present invention, the thickness of described the first acoustic board is greater than the thickness of described the second acoustic board.
The invention has the beneficial effects as follows: low-noise gear of the present invention can utilize described composite lubricating film and described absorbent treatment to absorb to greatest extent the noise that gear produces when work.
Description of drawings
Fig. 1 is the structural representation of low-noise gear one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, gear body, 2, the gear teeth, 3, vent, the 4, first acoustic board, 5, composite lubricating film.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made more explicit defining.
See also Fig. 1, Fig. 1 is the structural representation of low-noise gear one preferred embodiment of the present invention.
The invention provides a kind of low-noise gear, it comprises gear, composite lubricating film 6 and absorbent treatment, described gear comprises gear body 1 and the gear teeth 2, be provided with a plurality of vents 3 on described gear body 1, described absorbent treatment comprises the first acoustic board 4 and the second acoustic board (not sign), described composite lubricating film 6 is arranged on the described gear teeth 2, and described the first acoustic board 4 is arranged at the left side of described gear body 1, and described the second acoustic board is arranged at the right side of described gear body 1.
Described composite lubricating film 6 is pasted on the described gear teeth 1; described composite lubricating film 6 is by forming after lubricant agglomerates; can form with thin film on inner piece; he can protect gear to avoid the friction and wear impact; even can reduce wear and even corrode the gear teeth, can also rub to reduce gear noise by reduction.
Spacing between adjacent two described vents 3 is identical, and vent 3 can reduce the weight of gear self, can keep the original center of gravity of gear simultaneously, prevents centre-of gravity shift, thereby reduces the noise that gear produces.
The thickness of described the first acoustic board 4 is greater than the thickness of described the second acoustic board, the thickness of acoustic board has direct relation with the sound absorption frequency, increase along with material thickness, the sound absorption optimum frequency moves to the low frequency direction, 1 times of the every increase of thickness, the absorption maximum frequency moves an octave to the low frequency direction, and the thickness difference can absorb the noise of different frequency.
Low-noise gear of the present invention can utilize described composite lubricating film and described absorbent treatment to absorb to greatest extent the noise that gear produces when work.
The above is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
