Description
Technical field
The present invention relates to a kind of by claim 1 sealing housing cover as described in the preamble.
Background technique
By the known a kind of sealing housing cover of DE19928647C1 with the through hole that is used for axle to be sealed.Described sealing housing cover is used for the seal casinghousing opening, for example the crankcase of motor vehicle engine.Described sealing housing cover comprises the sealing flange of being made by metal or plastics, is integrated with the supporting mass of being made by metallic material in described sealing flange, and wherein said sealing flange is admitted and is used for the Sealing of seal casinghousing and admits bent axle.Simmer ring by dynamic seal (packing) is realized the sealing to bent axle, and realizes being the sealing of the crankcase of multi-part type in case of necessity by static seal.Two Sealings all are fixed on the sealing flange.
The sealing housing cover that only is made of plastics is because static state and the dynamic force between less housing can only be admitted and transmit to the lower intensity of material.In via regions, for sealing flange is fixed on the housing, because the impacting force that fastener occurs must be by the embedded piece of reinforcer-for example-be guided through sealing flange.
The sealing housing cover that only is made of metal is heavier than the sealing housing cover that is made of plastics, and the fixedly complexity of seal element.For the supporting mass that is become by the sheet metal stamping-out, the utilization ratio of material is low.
Sealing housing cover with the metal support of being surrounded by plastics is complicated on making, because must at first make supporting mass, with plastics described supporting mass is surrounded injection in ensuing treatment step.Supporting mass and plastics interconnect non-dismountablely in the sealing housing cover of making.
Summary of the invention
The objective of the invention is, improve the sealing housing cover of the described type of beginning like this, thereby can before being about to assembling, select the material of sealing housing cover, and the manufacturing of the single parts of sealing housing cover can be carried out independently of each other for the application corresponding occasion.
Utilize the feature of claim 1 to realize described purpose by the present invention.Dependent claims relates to preferred form of implementation.
In order to realize described purpose, imagine a kind of through-hole envelope closing cap that is used for axle to be sealed that has, it comprises the reinforcement flange of being made by metallic material of independent manufacturing and the sealing flange of making separately of being made by polymer material that has at least one Sealing, wherein during normal use, described reinforcement flange and sealing flange force closure and/or shape is sealed and/or material interconnects sealedly.
The reinforcement flange that is made of metal is by the bolt of fastener-for example-be connected with housing or housing member.Sealing flange accepts to act on the power that housings close covers.On sealing flange, be fixed with static sealing element that is used for seal casinghousing and the dynamic sealing element that is used for seal shaft.In another form of implementation, the static sealing element is installed in to be strengthened on the flange, and dynamic sealing element is fixed on the sealing flange.Sealing flange can be made by light metal, because sealing flange does not transmit power.Strengthen flange and sealing flange and interconnect, wherein the assembling of sealing flange and reinforcement flange can directly be carried out before assembling.Can adopt various sealing flange and the reinforcement flanges of optimizing at the application corresponding occasion thus, wherein for example can select to have the reinforcement flange of the expansion coefficient identical like this with the expansion coefficient of housing.Strengthening flange and sealing flange can be separated from each other after use again, can simplify the recycling of sealing housing cover thus.
Strengthening flange preferably can be made by aluminium or another kind of light metal.Reinforcement flange made of aluminum has less weight when having bigger intensity.Reinforcement flange made of aluminum can the pressing force casting technique be made, and also only has less process step even this makes under complex-shaped situation, and needs less manufacture cost thus.
In a form of implementation, the sealing flange of sealing housing cover can be made by polyamide (PA).Polyamide abrasion-proof decreases and shock resistance.
In another form of implementation, sealing flange can be made by polyphenylene sulfide (PPS).Polyphenylene sulfide has high strength and high chemical resistance, particularly also has high resistance for mineral and synthetic oiling agent.
In another form of implementation, sealing flange can be made by polyphthalamide (PPA).Polyphthalamide is a kind of heat resistant plastice, and this makes sealing housing cover to be used under the high temperature.
In a favourable form of implementation, sealing flange is connected with the reinforcement flange by at least one clamping locking part and/or locking locking part.These two kinds of sealed forms make can easily assemble connection and not take connection with being destroyed apart.
Sealing preferably can form by the sealing gasket of being made by polymer material (Dichtmanschette).Described sealing gasket is guaranteed with respect to axle to be sealed sealing housing cover to be sealed dynamically.Sealing gasket just has big supporting surface under the less situation of pressure force on axle to be sealed.Less by fricative thermal force thus.
Sealing gasket preferably can be made by a kind of PTFE compound/composite (Compound).Sealing gasket has resistance with respect to the medium of majority sealing usefulness thus.The PTFE material has good heat resistance, good sliding properties and extraordinary self-lubricating property in addition.The sealing gasket of being made by PTFE almost is not have wearing and tearing.
Sealing gasket preferably can have at least one in its side towards axle and be used for feeding back the feedback groove of sealing with medium along the direction in space to be sealed.Can improve the dynamic airtightness of seal ring by feeding back groove, wherein, however sealing gasket still always obtains lubricated fully.Oiling agent is formed with medium by sealing, and brings in constant renewal in by the feedback effect.
In a favourable form of implementation, Sealing comprises a sealing gasket and a seal lip that is arranged on the sealing gasket front towards surrounding environment.The seal lip that is arranged on the front prevents to enter into sealing gasket from the dirt particle of surrounding environment.Seal lip for example can be become by nonwoven fabric or felt.
Sealing flange is preferred to have a static seal of being made by polymer material in an axial side towards housing at least.Described static seal is guaranteed with respect to housing sealing housing cover to be sealed.
In a favourable form of implementation, the sealed and/or shape of described static seal and sealing flange material interconnects sealedly.By described static seal and the sealed form of implementation of sealing flange shape, two parts can immovably interconnect.Can improve the intensity of connection by bonding described two parts.But also can adopt the sealing material of self-sustaining/self-blocking.
In a form of implementation, sealing gasket can be along the direction prebuckling of surrounding environment.The feasible fitting tight ring simply of this layout, and needn't use assembly apparatus.
In another form of implementation, sealing gasket can be along the direction prebuckling in space to be sealed.This assembly direction allows to have along the high side medium pressure of situation of the trend of the direction of surrounding environment than sealing gasket.
In a favourable form of implementation, can be in sealing housing cover an integrated sensor device.Described sensor device makes rotating speed that can measurement axis, the stationarity and the corner of running, and wherein owing to be integrated in the sealing housing cover, the structure space of requirement is less, and proximity detector easily.
In a form of implementation, sensor is not pulled down from sealing housing cover with can being destroyed.Thus can be specially emat sensor more, perhaps after dismounting, can continue to use sensor.
In a favourable form of implementation, when finish working life, can take apart and strengthen being connected of flange and sealing flange, and two flanges can utilize and/or handle dividually again.Can avoid complicated processing thus to the connection material.
