Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of embodiment.It will be appreciated that, mentioned in following mode of execution of the present utility model " on ", D score, " left side ", " right side ", " front " and " reverse side " be all take the direction shown in each figure as benchmark, these words that are used for limiting direction are only used to be convenient to explanation, do not represent the restriction to the concrete technological scheme of the utility model.
The noise reduction insulation board of gear chamber housing of the present utility model is simple and reasonable, by the high damping working of plastics that adopts cast inblock to form, and coordinate with O RunddichtringO, be applied in engine gear case housing internal noise and concentrate place, thereby effectively reduce the vibration and noise of gear chamber housing and complete machine, the harmful effect that weak noise and vibration brings.
Detailed description by way of example but unrestriced mode has illustrated the disclosure, should be understood that the realization that can be combined by independent realization or with other aspects in various aspect of the present disclosure below.This specification clearly enables those skilled in the art to manufacture and uses us to believe for new and non-obvious improvement, describe some embodiments, alternative, modification, alternative and system applies, comprised the current best mode that is considered to carry out the model utility principle of describing in this specification.In the time describing element or feature and/or embodiment, be intended to expression titled with " one " " one " " be somebody's turn to do " and " described " and there are one or more in element or feature.Term " comprises " that " comprising " and " having " is intended to is comprising property, and also has extra element or feature beyond being illustrated in those specifically described elements or feature.
As shown in Figure 1, the noise reduction insulation board of this gear chamber housing is the working of plastics that cast inblock forms, its concrete structure comprises: top board 1 and along the bottom surface of this top board 1 to the buckle 2 of downward-extension, the bottom surface of top board 1, the external circumferential of buckle 2 offer seal groove 11, for placing seal ring.Concentrate the end face opening (consistent size that opening size combines with the noise reduction insulation board of this gear chamber housing) at place at gear chamber housing internal noise, seal ring is arranged in seal groove 11, then the noise reduction insulation board of this gear chamber housing is pressed into housing opening by buckle 2 tightly fastens.The noise reduction insulation board of this gear chamber housing is the working of plastics that cast inblock forms, and the overall weight of gear chamber housing is alleviated, and change its natural frequency, avoids motor resonant frequency, reduces noise, alleviates vibration.
As shown in Figures 2 and 3, top board 1 is circular plate, and end face adopts the waveform design of different radii, interferes with each other decay while making Acoustic Wave Propagation, makes the noise reduction insulation board noise reduction of this gear chamber housing obvious.Seal groove 11 is annular, and for placing O RunddichtringO 3, O RunddichtringO 3 adopts location, outer ring to prevent this gear chamber housing leakage of oil in order to sealing.This gear chamber noise reduction insulation board adopts O type circle outer ring location sealing; in the situation that there is certain pressure in inside; O type circle not only can produce seal ring with groove upper wall and lower wall; can also produce seal ring, the noise reduction insulation board of more effective sealing gear chamber housing under duplicate protection with the outer ring sidewall of seal groove.The bottom surface of top board 1 is laid with many stiffening ribs 12 along top board 1 radially outward radiation by central authorities, the end of stiffening rib 12 extends to the inner side surface of buckle 2, many stiffening rib 12 is circumferentially evenly laid along the bottom surface of top board 1, can improve the rigidity of the noise reduction insulation board of this gear chamber housing, avoid the noise reduction insulation board distortion of gear chamber housing and affect sealing, the stiffening rib 12 of the present embodiment is uniform eight.
As shown in Figure 4, buckle 2 is the annular buckle to downward-extension along the bottom surface of this top board 1, the end of buckle 2 has the buckle oblique angle 21 playing the guiding role, all sides of buckle 2 offer the multiple fractures 22 that run through inner and outer surface, multiple fractures 22 are consistent with the bearing of trend of buckle 2, and circumferentially uniform along buckle 2.In the time that the noise reduction insulation board of gear chamber housing is pressed into housing, due to the leading role at buckle oblique angle 21, naturally inwardly shrink with the buckle 2 of fracture 22, through after housing opening, the reset condition of rebounding, realizes the function of stuck housing.The noise reduction insulation board buckle structure of this gear chamber housing and the layout of stiffening rib make its rigidity moderate, easy for installation, and sealing is reliable again.The fracture 22 of the present embodiment is uniform eight.
As shown in Figure 5, when use, first concentrate the end face opening (consistent size that opening size combines with the noise reduction insulation board of this gear chamber housing) at place at gear chamber housing 4 internal noises, seal ring is arranged in seal groove 11, then the noise reduction insulation board of this gear chamber housing is pressed into housing opening by buckle 2 tightly fastens.After the application of this scheme, make housing weight saving, thereby and reduce to a certain extent complete machine weight and reduce oil consumption; In addition, the noise reduction insulation board of this gear chamber housing has changed the natural frequency of gear chamber housing, avoids motor resonant frequency, reduces noise, alleviates vibration, the NVH value of surveying by reality, and its sound quality is better.
To sum up, the noise reduction insulation board of this gear chamber housing is simple and reasonable, by the high damping working of plastics that adopts cast inblock to form, and coordinate with O RunddichtringO, be applied in engine gear case housing internal noise and concentrate place, thereby effectively reduce the vibration and noise of gear chamber housing and complete machine, the harmful effect that weak noise and vibration brings.
Finally it should be noted that: above embodiment is only in order to illustrate the utility model and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can modify or be equal to replacement the utility model; And all do not depart from technological scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in claim scope of the present utility model.
