Definitions
- the present invention relates to a sealing bellows intended to ensure the sealing of a joint, of transmission connecting two shafts, of the type defined in the preamble of claim, 1.
- a sealing bellows intended to ensure the sealing of a joint, of transmission connecting two shafts, of the type defined in the preamble of claim, 1.
- Such a type of sealing bellows is frequently found disposed on two shafts, for example connected by a joint or a constant velocity joint, such as a tripod joint.
- These bellows are made of elastomer and have concentric or helical folds and confine the lubricant in which the joint or joint is immersed.
- the fixing of this type of bellows is carried out, in a known manner, by the tightening of fixing members on each of the heels of the bellows, thus tightening it firmly against each of the shafts or against a part integral with each shaft.
- These fixing members can be closed rings,. necklaces, in particular with ear, or any other appropriate element.
- the fixing members are closed rings crimped by necking
- a difficulty arises. Indeed, the operation of crimping a fixing ring on the bearing surface of the heel requires threading and positioning the ring on the heel, then constricting it to bring it by plastic deformation to its mounted state.
- the constriction of the fixing ring then consists of a first phase of deformation of this ring to bring its internal surface into simple contact with the bearing surface r of the heel, then of a second phase of deformation of the ring for make it penetrate into the heel by compressing the bearing surface.
- the first deformation phase does not contribute to the tightening between the heel and the corresponding shaft.
- this first phase involves a first level of plastic deformation of the fixing ring, thus increasing the risks of its deterioration and / or breakage during the second mounting phase, in particular if • this assembly is automated, or during subsequent stresses during operation.
- the object of the invention is to prevent the drawbacks mentioned above by proposing a bellows which guarantees an excellent seal and the mounting of which reduces the risk of error in positioning and premature deterioration of the fixing members.
- this object is achieved with a sealing bellows of the aforementioned type and comprising the characteristics of the characterizing part of claim 1.
- the bellows may comprise one or more of the characteristics of claims 2 to 4, taken in isolation or in any technically possible combination.
- the invention also relates to a transmission joint defined in claim 5.
- Other characteristics of the transmission joint according to the invention are described in claims 6 to 8.
- the invention also relates to a method of fixing a sealing bellows to form a transmission joint defined in claim 9. Other characteristics of the method according to the invention are described in claims 10 and 11.
- FIG. 2 is a cross-sectional view of the seal shown in Figure 1 along the line II-II;
- - Figures 3a, 3b and 3c are simplified longitudinal sectional views corresponding to the circled area III in the figure. 1;
- Figure 3a shows the end of the bellows according to the invention, the member. fixing and the female element of the seal before mounting;
- Figure 3b shows these elements positioned relative to each other before the fastening of the fixing member;
- FIG. 3c represents the final state of the end of the bellows tightened on the female element of the seal;
- - Figures 4a, 4b and 4c are similar views respectively
- FIG. 5 is a view similar to Figure 3b, but of a seal from the prior art.
- a transmission joint 1 according to the invention, connecting a first shaft 4 and a second shaft 6.
- the two shafts 4 and 6 are connected by a mechanical transmission member not shown in detail which requires a good lubrication, especially with grease.
- the confinement of this lubricant at the joint is ensured by the bellows 2, which is fixed at its small end on the shaft 4, integral with the male element 5 of the joint, and which is fixed at its large end on the periphery of a female element 7 of the seal, integral with the shaft 6.
- the bellows comprises a bellows body 10, consisting of an elastic membrane, of plastic material, with several folds of increasing diameter from the shaft 4. Each end of the bellows is in the form of a heel 11, 12.
- the internal surface of the heel 11, 12 is intended to be tightly sealed against the periphery of the associated member.
- the heel 11 is mounted in tight contact on the shaft 4 and the heel 12 on the element 7.
- the seal 1 is a tripod seal
- the male element 5 has three roller journals 8, angularly spaced 120 ° from each other.
- the female element 7 has housings 9, each intended to receive a roller 8.
- the outer profile, relative. at the axis of the shaft 6, the female element 7 is therefore three-lobed and made up of the succession of external profiles of these housings 9, as shown in FIG. 2.
- the internal profile of the heel 12 has a certain number of protrusions directed towards the interior of the joint so that it is complementary to the external profile of the female element 7 previously described.
- the heel 12 thus has a three-pronged internal profile, while its external surface has a circular section.
- FIG. 3a are shown the heel 12 of the bellows 2 according to the invention, a fixing member 22 and the end of the female element 7 furthest inside the joint.
- the heel 12 has a radially outer shoulder 16 which transitions between the bellows body 10 and the heel 12.
- the heel comprises, from the shoulder 16 and up to its end, a bearing surface 20 intended to receive the fixing member 22.
- the bearing surface 20 is substantially cylindrical and coaxial with the heel.
- the inner profile in longitudinal section of the heel 12 has several projections 21, substantially V-shaped and directed towards the inside of the joint. These projections 21 are intended to form sealing lines when the heel 12 is mounted tight against the associated element 7.
- the fixing member 22 is in the form of a closed ring, of steel or aluminum.
- the external surface of the female element 7 has an annular groove 23 located near the end of the element 7.
- the profile in longitudinal section of this cavity 23 is intended to cooperate with the projections 21 of the internal profile of the heel 12 to form the sealing lines mentioned above.
- the mounting of the bellows 2 consists first of all in positioning this bellows on the elements 4, 7 of the seal for which sealing is sought. Will only be described below the details of the mounting of the heel 12 on the female element 7 by way of example, it being understood that the mounting of the heel 11 on the shaft 4 is similar.
- the fastener 22 is then slipped onto the heel 12 with a slight radial clearance, and is positioned longitudinally so that it is brought vis-à-vis the bearing surface 20, as shown in Figure 3b, using the shoulder 16 as a positioning stop.
- the fastening member 22 is constricted in order to radially compress the bearing surface 20, thereby applying a clamping stress on the heel 12 on the associated element 7 and causing a neck to appear at the end of the heel 12.
- end 24 radially projecting.
- the mounted state of the heel 12 on the element 7 is shown in FIG. 3c.
- the tightening consists in the application of a uniform peripheral force on the external surface of the ring.
- the ring already practically in simple contact with the heel 12, then plastically deforms into a constriction and penetrates by crimping into the heel 12, crushing the bearing surface 20 and causing the end neck 24 to appear.
- Figure 5 shows a view identical to Figure 3b, but whose bellows 2 is according to the prior art.
- the heel 12 of the bellows 2 comprises the same elements as above, but it also comprises, in the free state, an end collar 28 situated at the end of the heel 12 and extending radially outwards.
- the mounting before tightening of such a bellows illustrated in FIG. 5 implies that the fastening member 22 is threaded on the heel by crossing the neck 28 with a slight radial clearance, before being positioned opposite. the support surface 20.
- the heel of the bellows according to the invention in the free state, does not have an end collar but an end surface in extension of the support surface 20, no prior deformation of the fixing member 22 is not necessary during assembly to bring it into contact with the bearing surface 20.
- the member 22 has at rest an internal diameter barely greater than the diameter of this surface 20.
- the joint 1 comprising a bellows according to the invention makes it possible to reduce the deformation value of the fixing member 22, that is to say the difference between the inside diameter of the fastening member 22 in the free state and that after tight assembly, with respect to seals of the same type pertaining to the prior art. The reliability and the reproducibility of the tightening of the heels are consequently improved.
- Figure 4a shows a second embodiment of the invention.
- the heel 12 of the bellows 2 according to this embodiment has the same elements as that relating to the first embodiment. shown in Figure 3a, namely a bearing surface 20 and a shoulder 16 radially outside.
- the bearing surface 20 also has a circular groove 26.
- FIG. 4b The mounting of the bellows 12 according to this second embodiment is illustrated in FIG. 4b. It is identical to that of the first embodiment.
- this groove 26 serves as a visual marker for longitudinal positioning of the fixing member 22 in the case where this groove 26 is located at a distance substantially equal to the length of the internal surface of the fixing member 22. Due to this positioning relative to the groove 26, a slight axial play may remain between the shoulder 16 and the fixing member 28 before tightening.
- the tightening of the fixing member 22 is illustrated in FIG. 4c and is described in the same terms as in the case of FIG. 3c.
- the tightening of the fixing member 22 shows an end neck 24 forming a stop, while partially or completely making the groove 26 disappear from the crushed support surface 20.
- the transmission joint 1 when the fixing member 22 is mounted tightly, the transmission joint 1 has a bellows fixed in sealed contact against each of the shafts or of parts integral with the shafts, with a projecting stop on each side of the fixing member.
- the profile in. transverse section of the external surface of the heel 12 is not limited to a circular profile, but may have protrusions directed towards the outside, in particular facing screw of the housings 9 of the female element 7, so that the tight heel has a substantially constant material thickness over its entire section.
- the ring 22 then has, at rest, a corresponding non-circular profile. The tightening pressure is thus distributed more evenly within the material of the heel.
- the closed ring can be replaced by an ear collar as the fixing member 22.
- the tightening then consists in applying a. pinching force at the base of the ear with which such a collar is conventionally provided, already practically in simple contact with the heel 12. Pinching the ear causes the inner diameter of the collar to decrease, which penetrates into the heel 12, showing the end collar 24.
