Abstract
The utility model discloses a gear, which includes a gear body (1), wherein a plurality of through holes (2) are uniformly distributed in the circumferential direction on the end surface of the gear body (1); and foamed aluminum filler (3) is arranged every through hole (2). The gear can effectively reduce the noise generated during the gear rotation.
Description
Technical field
The utility model relates to a kind of mechanical parts, particularly a kind of gear.
Background technique
Gear is a kind of common mechanical transmission part, in transmission process, because result of various factor comprehensive action produces noise, vibrates.Eliminate noise, the normal method of using is optimized profile of tooth for optimizing the design of gears parameter; Or the improvement manufacturing process, improve the Gear Processing precision, reduce alignment error etc.; But it is big to improve difficulty, has increased design and manufacture cost greatly.In addition, the gear of market circulation at present is because requirement of strength mostly is cast iron materials, and weight is heavier, so the energy that transmission consumed is big.
The model utility content
Technical problem to be solved in the utility model is: provides a kind of and has the vibration and noise reducing function, and the relative lighter gear of weight.
The technical scheme in the invention for solving the above technical problem is: a kind of gear, comprise the gear body, and the end face upper edge of described gear body circumferentially is evenly equipped with a plurality of through holes, is equipped with the filled with foam aluminum thing in described each through hole.
Compared with prior art, advantage of the present utility model is: owing to circumferentially be laid with a plurality of through holes on gear face, and all be filled with the filled with foam aluminum thing in each through hole, this has just not only reduced weight, and when the gear rotation is subjected to vibrating, can effectively be absorbed by foamed aluminium material, thereby reduce noise and vibration, very favourable to the working life of improving gear.
As preferably, circumferentially be evenly equipped with four through holes on the end face of described gear body.
As preferably, described filled with foam aluminum thing interference fit is in described through hole.
Description of drawings
Fig. 1 is the perspective view of the utility model gear.
Shown in the figure: 1 gear body, 2 through holes, 3 filled with foam aluminum things.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As shown in drawings, a kind of gear comprises gear body 1, circumferentially is evenly equipped with a plurality of through holes 2 in the end face upper edge of gear body 1, is equipped with filled with foam aluminum thing 3 in described each through hole 2.
Circumferentially be evenly equipped with four through holes 2 on the end face of described gear body 1.
Described filled with foam aluminum thing 3 interference fit are in described through hole 2.
Claims (3)
1. a gear comprises gear body (1), it is characterized in that: circumferentially be evenly equipped with a plurality of through holes (2) in the end face upper edge of gear body (1), be equipped with filled with foam aluminum thing (3) in described each through hole (2).
2. gear according to claim 1 is characterized in that: circumferentially be evenly equipped with four through holes (2) on the end face of described gear body (1).
3. gear according to claim 1 is characterized in that: described filled with foam aluminum thing (3) interference fit is in described through hole (2).
