Abstract
The utility model discloses a front end sealing device for a clutch release bearing, which comprises an enclosure and a sealing ring fixed on the inner side of the end surface of the enclosure, wherein the sealing ring comprises a radial installation edge and a conical inner sealing lip and has U-shaped section, and the radial installation edge of the sealing ring is fixedly connected with the inner side of the end surface of the enclosure. The front end sealing device for the clutch release bearing is simple in structure and convenient to assemble, the sealing ring and the enclosure are fixedly connected into a whole, the enclosure only needs to be directly rolled on an outer ring of a bearing in assembling, and the enclosure is hard to loosen and fall off after rolling, simultaneously the installation steps of the sealing ring are saved; therefore, the assembling efficiency is high, the sealing ring is accurate in positioning; turning, twisting, deviating and other phenomena are uneasy to occur; the whole device is good in sealing effect, and the service life of the clutch release bearing is ensured.
Description
Technical field
The utility model relates to a kind of associated sealing arrangement for bearings, and especially a kind of clutch release bearing seal arrangement that is used for automobile hydraulic double clutch system belongs to technical field of bearings.
Background technique
Automobile clutch is between motor car engine and speed changer, and its main effect is the transmission of power of when the automobile conversion keeps off, cutting off between motor and speed changer, the impulsive load of speed change gear and prevent the transmission system overload when alleviating the conversion retaining.Hydraulic coupling is that transmission device adopts hydraulicdriven clutch system; Automobile double clutch is on the basis of original single clutch system, to increase a clutch system; Two systems are used alternatingly to reduce the automobile gear shift time, the transmission of power stagnation behavior when eliminating gearshift.Being installed on the automobile clutch transmission main shaft of clutch release bearing cut off motor car engine and got in touch with the power between speed changer and/or the power human transporting axle thereby move axially through it, accomplishes vehicle starting, stops and gearshift etc. is operated.In the hydraulic double clutch system, because assembly space is limited, require clutch release bearing compact structure, wear-resistant, favorable sealing property, to guarantee the working life of bearing.The inside and outside circle of existing hydraulic coupling release bearing adopts steel plate to be stamped to form more; Generally be provided with the seal groove of installation shaft brought forward end seal ring in the bearing outer ring end; Because bearing outer ring is originally as stamping part; Receive its wall thickness restriction seal groove groove depth generally more shallow, cause seal ring in packing, transportation or using process, to be prone to come off.For overcoming above-mentioned defective; Be employed in the structural type of clamping seal ring between bearing outer ring end face and the bearing outer cover, but this sealing configuration assembly process is loaded down with trivial details, and because seal ring is generally softer rubber material; Location difficulty during assembling; Seal ring turns over easily and turns round, crooked, cause the seal ring seal lip portion to be clamped between bearing outer ring periphery and the bearing outer cover inner headed face, and some seal ring positive and negative is difficult for differentiating; Dress is anti-easily during assembling, and these have all influenced the sealing effect and the working life of bearing greatly.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, easy to assembly, clutch release bearing forward end seal device that sealing effect is good.
The utility model is achieved through following technological scheme:
A kind of clutch release bearing forward end seal device; Comprise outer cover, be fixed on the inboard seal ring of outer cover end face; Said seal ring comprises radially installs sealing lip in limit, the taper, and the seal ring cross section takes the shape of the letter U, and said seal ring is radially installed the limit and is fixedly connected with the outer cover end face is inboard.
The purpose of the utility model can also further realize through following technical measures.
Aforesaid clutch release bearing forward end seal device, the outer arc face shape of the axial limit of wherein said outer cover and bearing outer ring is coincide.
Aforesaid clutch release bearing forward end seal device, the exterior edge face of wherein said seal ring is not higher than the end face of outer cover.
The utility model is simple in structure, and is easy to assembly, and seal ring and outer cover are fixedly connected into integral body; Only need during assembling the direct roll extrusion of outer cover is got final product on bearing outer ring, the outer arc face shape of the axial limit of outer cover and bearing outer ring is coincide after the roll extrusion, and outer cover is difficult for loose or dislocation; Saved the installation steps of seal ring simultaneously, efficiency of assembling is high, the seal ring accurate positioning; Difficult turning over such as turns round, crooked at phenomenon, and whole device sealing effect is good, has guaranteed the working life of clutch release bearing.
Advantage of the utility model and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain that these embodiments only provide with reference to accompanying drawing as an example.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the I portion enlarged view of Fig. 1;
Fig. 3 is that the utility model is installed in the structural representation on the clutch release bearing.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Like Fig. 1～shown in Figure 3; The utility model comprises outer cover 1, is fixed on the inboard seal ring 2 of outer cover 1 end face; Outer cover 1 is stamped to form by steel plate, and seal ring 2 is the rubber material, and seal ring 2 comprises radially installs sealing lip 22 in limit 21, the taper; Seal ring 2 cross sections take the shape of the letter U; It radially installs limit 21 and the inboard gummed of outer cover 1 end face, and the exterior edge face 23 of gummed back seal ring 2 is concordant with the end face of outer cover 1 or be lower than the end face of outer cover 1, and the axial limit 11 of outer cover 1 is identical with the outer arc face shape of bearing outer ring 3.
Be provided with gap a between the radially installation limit 21 of seal ring 2 and 11 inboards, outer cover 1 axial limit; Gap a can be less than the thickness b of bearing outer ring 3, and at this moment, seal ring 2 is clamped between bearing outer ring 3 end faces and the outer cover 1 end face inboard; Gap a also can be greater than the thickness b of bearing outer ring 3; This moment, bearing outer ring 3 end faces were resisted against on the outer cover 1 end face inboard, played better sealing effect, and are as shown in Figure 3.
During the release bearing assembling; Only need the 1 direct roll extrusion of the utility model outer cover is got final product on bearing outer ring 3; Because, having guaranteed outer cover 1 less than the maximum outside diameter of bearing outer ring 3, the mouth diameters of outer cover 1 is difficult for loose or dislocation from the bearing outer ring 3, good sealing effect after the roll extrusion.
Except that the foregoing description, the utility model can also have other mode of executions, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
