Abstract
The invention discloses a noise elimination vibration reduction gear which comprises a gear body, and further comprises an oil storage cavity, an elastic pressing piece and a foamed aluminium noise elimination layer, wherein teeth are arranged on the outer contour of the gear body; tooth grooves are formed between the adjacent teeth; a shaft hole is formed in the central position of the gear body; a keyway is formed in the inner wall of the shaft hole in the radial direction of the gear body; the oil storage cavity is formed inside the gear body; oil ducts are formed in the inner cavity wall of the oil storage cavity; the oil ducts are distributed on all the tooth grooves, and communicate with the upper surfaces of the tooth grooves; oil suction devices are arranged in the middle parts of the oil ducts; the elastic pressing piece is mounted around the inner wall of the shaft hole; and the foamed aluminium noise elimination layer is arranged on the inner wall of the oil storage cavity. According to the noise elimination vibration reduction gear, through the arranged elastic pressing piece, the oil ducts and the foamed aluminium noise elimination layer, when the gear runs, the elastic pressing piece reduces the friction of the shaft hole and a bearing, the oil ducts prevent the teeth from having dry friction, and the foamed aluminium noise elimination layer has a sound insulation effect.
Description
Technical field
The present invention relates to field of gears, particularly relate to a kind of sound deadening shock absorption gear.
Background technology
nullSince second industrial revolution，The application of machinery closely occupies whole manufacturing，Gear is then the important component part of operating between mechanical each parts，But gear on-stream generation noise is bigger，And in gear train，Difference according to mechanism，Noise can be divided into again acceleration noise and ring noise two kinds，On the one hand，When gear tooth engages，Make gear produce very big acceleration and surrounding medium disturbance can be caused due to impact，The acoustic radiation produced by this disturbance is called the acceleration noise of gear，On the other hand，Under gear dynamic engagement force effect，Each parts of system can produce vibration，The produced acoustic radiation of these vibrations is called ring noise，And gear is in that when bearing is installed，Owing to axis hole and bearing do not have the so accurate of reality when processing，Therefore there is gap between axle hole branch and bearing，Will be not accurate because of gear and bearing fit when pinion rotation，Noise and vibrations are produced when causing rotating.
Summary of the invention
The invention aims to overcome the deficiencies in the prior art, it is provided that a kind of sound deadening shock absorption gear.
The present invention is achieved through the following technical solutions:
A kind of sound deadening shock absorption gear, including gear, described gear outline is provided with teeth, it is provided with teeth groove between adjacent teeth, described gear center offers axis hole, keyway is offered on the inwall of axis hole and along the radial direction of gear, described sound deadening shock absorption gear also includes, oil storage cavity, elastic pressuring plate, foamed aluminium noise reduction layer, oil storage cavity is offered inside described gear, oil storage cavity internal chamber wall offers oil duct, and oil duct is distributed on each teeth groove, oil duct and teeth groove upper surface connect, and oil duct middle part is provided with Oil sucking device, in shaft hole inner wall surrounding, elastic pressuring plate is installed, the inwall of oil storage cavity is provided with foamed aluminium noise reduction layer.
Further, described Oil sucking device is that polypropylene is made, and size matches with oil duct diameter.
Further, described elastic pressuring plate adopts polyurethane material to make.
Further, described foamed aluminium noise reduction layer is bonded on the inwall of described oil storage cavity by adhesive, and its thickness is 5mm-10mm.
Compared with prior art, the invention has the beneficial effects as follows: present configuration is novel, reasonable in design, by arranging elastic pressuring plate and oil duct and filled and process aluminum noise reduction layer, when gear is in operation process, elastic pressuring plate can play the friction of axis hole and the bearing reducing gear, and oil duct then serves and prevents teeth from dry friction occur, and foamed aluminium noise reduction layer then serves the effect of sound insulation, thus reducing the effect of noise and damping, also extend the service life of gear.

Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated, it should be understood that, specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of sound deadening shock absorption gear that the present embodiment provides, including gear 3, described gear 3 outline is provided with teeth 1, is provided with teeth groove 2 between adjacent teeth 1, and described gear 3 center offers axis hole 5, keyway 4 is offered on the inwall of axis hole 5 and along the radial direction of gear 3, gear 3 surface is covered with nickel coating, it is possible to reduce situation about getting rusty occurs in long-time use procedure in gear, thus extending its service life.
Described sound deadening shock absorption gear also includes oil storage cavity 10, elastic pressuring plate 7, foamed aluminium noise reduction layer 6, oil storage cavity 10 is offered inside described gear 3, oil storage cavity 10 internal chamber wall offers oil duct 9, and oil duct 9 is distributed on each teeth groove 2, oil duct 9 and teeth groove 2 upper surface connect, and oil duct 7 middle part is provided with Oil sucking device 8, in axis hole 5 inwall surrounding, elastic pressuring plate 7 is installed, the inwall of oil storage cavity 10 is provided with foamed aluminium noise reduction layer 6.Make when gear is installed with bearing, elastic pressuring plate 7 can reduce the gap between its gear shaft holes 5 and bearing, and inside through hole 11, it is filled with foamed aluminium noise reduction layer, foamed aluminium noise reduction layer can play the effect of sound insulation and noise reduction, therefore gear noise in operation process be can reduce and gear shaft holes 5 and the vibrations of bearing generation alleviated, by offering oil duct 9 at gear, and in the middle of oil duct 9, Oil sucking device 8 is installed, Oil sucking device 8 is made for polypropylene, because polypropylene is oil absorption material, in gear operation process, polypropylene can absorb the lubricating oil in oil storage cavity 6, and flow in teeth groove 2 by oil duct 9, two gears thus can be made when engaging each other, do not have dry friction, cause teeth serious wear, serve the effect of protection teeth, extend the service life of gear.
In the present embodiment: described elastic pressuring plate 7 polyurethane material is made, and polyurethane material has the function of oil suction, it is possible to absorb the oil that gear shaft holes 5 is unnecessary with on bearing, reach the purpose of fuel-economizing.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within protection scope of the present invention.
