Abstract
The utility model provides a vibration and noise reduction gear, belonging to the technical field of machinery. The utility model solves the problem that the vibration and noise reduction effect of the existing gear is poor. The vibration and noise reduction gear comprises a circular disc-shaped gear body and teeth arranged on the external circumference of the gear body. Annular grooves are arranged on the two side surfaces of the gear body. A damping piece I with vibration and noise reduction function and a damping piece II with vibration and noise reduction function are respectively arranged in the annular grooves. The damping piece I and the damping piece II are fixedly connected on the gear body. Since the annular grooves are arranged on the two sides of the vibration and noise reduction gear and the damping pieces are arranged in the annular grooves, the utility model has the advantages that the weight of the gear is reduced, the automobile load is reduced, the partial vibration energy of the gear can be absorbed, the transmission vibration and noise of the gear pair are reduced and the transmission in the gearbox is kept to be stable.

The NVH of speed changer is produced by vibrations such as the gear in the speed changer, axle, bearing, housings, and vibration that gear produces and impact are the emphasis of speed changer NVH research, also are difficult points.Vibration and noise that gear produces are result of various factor comprehensive action; The main method of control is to eliminate or weaken the power of enforcement that evokes gear noiose, to vibration, the noise that has produced insulate against sound, measures such as vibration isolation, shielding and elimination.
As China Patent No. is the patent of " ZL 200720185373.6 ", a kind of vibration and noise reducing gear is provided, be made up of gear mass, teeth, evenly divide on the wheel abdomen between tooth root and the fixed hole cylindrical and lay a plurality of through holes, interference fit is equipped with the foamed aluminium casting resin in the through hole.Though above-mentioned gear also can play the vibration and noise reducing effect, in use easily because of long-term vibration causes the foamed aluminium casting resin loosening, the effect of its noise reduction vibration damping is also not obvious for the gear of this structure.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of simple in structurely, can effectively reduce vibration, reduce the vibration and noise reducing gear of noise.
The purpose of this utility model can realize by following technical proposal: a kind of vibration and noise reducing gear, comprise discoid gear mass and be opened in teeth on the excircle of gear mass, it is characterized in that, the both sides of described gear mass are respectively equipped with the damping piece one and the damping piece two that can play the vibration and noise reducing effect, and described damping piece one and damping piece two are connected on the gear mass.
Vibration and noise reducing gear of the present utility model is in the form of annular discs, is used in the speed changer of automobile, and teeth are arranged on the excircle of gear mass.Damping piece one and damping piece two have absorbing, noise reduction effect, damping piece one and damping piece two are set, vibration that forms in the time of can reducing the meshed gears transmission and noise on the both sides of gear mass respectively.
In above-mentioned vibration and noise reducing gear, have annular groove on the bi-side of described gear mass, above-mentioned damping piece one and damping piece two are located at respectively in the annular groove of both sides.Both sides are provided with annular groove, have not only alleviated the weight of gear, and are easy to place damping piece one and damping piece two.
In above-mentioned vibration and noise reducing gear, have several through holes on the described gear mass, described through hole is connected with above-mentioned annular groove.This through hole is convenient to damping piece one and damping piece and gear mass and is connected.
In above-mentioned vibration and noise reducing gear, be provided with damping piece three in the described through hole, described damping piece three is connected with above-mentioned damping piece one and damping piece two.Damping piece three is set can play better vibration and noise reducing effect to gear, has reduced the fixedly device of damping piece one and damping piece two simultaneously.
In above-mentioned vibration and noise reducing gear, described damping piece three and above-mentioned damping piece one and damping piece two are connected as a single entity.This setting can be fixed on the gear mass three damping pieces reliably.
In above-mentioned vibration and noise reducing gear, described damping piece one, damping piece two and damping piece three are made by nonmetallic material.
In above-mentioned vibration and noise reducing gear, described damping piece one, damping piece two and damping piece three are formed by one or more material shots in butyl, acrylate, poly-sulphur, butyronitrile and silicone rubber, polyurethane, PVC or the epoxy resin.
Compared with prior art, vibration and noise reducing design of gears of the present utility model is reasonable, effect of vibration and noise reduction is obvious, not only reduced the swept area of gear vibration source, alleviated the weight of gear, reduce the automobile load, and can absorb the energy of a part of gear vibration, and reduce the vibrations and the noise of gear pair, make stable drive in the speed changer.
