Definitions
- the invention relates to a rolling bellows for sealing two rotating, mutually bendable and / or mutually axially displaceable rotating parts with a longitudinal and symmetrical axis A, comprising a first collar of smaller diameter for fixing on a first rotary part of smaller diameter, a second collar of larger diameter for fixing on a second rotary part of larger diameter, and extending in diameter from the smaller first collar to the larger second collar annular wall.
- Roll bellows of this type exist depending on the intended use of rubber elastomers or plastic thermoplastics or certain mixtures thereof. Depending on the material, they are produced by injection molding or blow molding.
- Well-known rolling bellows have in the state of manufacture a conical annular wall extending from the smaller first collar to the larger second collar, which is deflected back from the larger collar after demoulding such that the second larger collar is axially relatively close to the smaller first collar and radially outward the annular wall, which is thus partially radially double-walled. It forms a schbtorusförmiges structure showing a substantially C-shaped apex of curvature (apex) in the longitudinal half section, which is located axially from the first collar and second collar furthest away.
- annular wall in the state of manufacture on the non-clamped rolling bellows in the longitudinal half section has an S-shaped curve with an inner curvature next to the smaller first collar and an outer curvature next to the larger second collar.
- the rolling bellows described herewith already has a more favorable increased radius of curvature of the annular wall in the region of the apex of curvature in the statically installed state compared to rolling bellows according to the prior art.
- said S-shaped profile of the rolling bellows can be more or less stretched in the state of manufacture, ie the annular wall length in the axial direction can be adapted to the application. For given stress collectives, shortened annular wall lengths are possible in comparison with rolling bellows according to the prior art.
- a second solution is that the annular wall in the state of manufacture on the non-clamped rolling bellows in the longitudinal half section has a C-shaped course with an inner curvature between the smaller first collar and the larger second collar.
- the annular wall adjoins the smaller first collar on the non-clamped rolling bellows approximately axially parallel to the longitudinal axis A. Furthermore, it is preferably provided that the annular wall connects in the state of manufacture on the non-clamped rolling bellows in the longitudinal half section at an acute angle to the longitudinal axis A to the larger second collar.
- the smaller first collar is thickened inwardly relative to the annular wall.
- a contact of the annular wall with the smaller-diameter rotary part is avoided in bending of the rotating parts against each other.
- the smaller first collar has an outside annular groove for receiving a tension band.
- a longitudinal displacement of the first collar on the first rotation part can be prevented, whereby preferably also an annular groove can be provided on the outside on the first rotation part.
- the larger second collar is formed as a rounded bead.
- an annular connecting cap in which the second collar is crimped.
- Such a connection cap as a second rotation part or as a transition piece to the second rotation part has preferably starting from the second collar initially a cylindrical shape.
- the annular wall can partially create under the influence of centrifugal forces. This is taken into account in the intended favorable design of the radius of curvature of the annular wall under the influence of centrifugal forces.
- FIG. 1 shows a rolling bellows according to the invention in the state of manufacture in a first embodiment a) in a longitudinal section b) in perspektivischer.Ansicht;
- FIG. 2 shows the rolling bellows according to FIG. 1 in longitudinal section a) in the state of production b) in inverted mounted form without centrifugal force c) in inverted mounted form under the influence of centrifugal force;
- FIG. 3 shows a rolling bellows according to the invention in the state of manufacture in a second embodiment a) in a longitudinal section b) in a perspective view;
- Figure 4 shows the rolling bellows of Figure 3 in the longitudinal half-section a) in the state of manufacture b) in everted mounted form centrifugal force-free c) in inverted mounted form under centrifugal force influence.
- FIG. 1 There is shown a rolling bellows 10 according to the invention at the stage of manufacture after being formed from a mold.
- the rolling bellows is formed around a symmetrical to a longitudinal axis A.
- the rolling bellows are shown in its lowest-tension self-adjusting form.
- a first collar 11 with a smaller diameter and a second collar 12 with a larger diameter can be seen. Both are joined by a ring wall 13, widening in diameter from the first collar to the second collar, which is made in one piece with both.
- a thin-walled protective sleeve 14 whose smallest diameter is formed at its free end.
- the first collar 11 is provided for fixing on a first rotary part, in particular a drive shaft. He has a substantially inner cylindrical seat surface 15 and on the outside of an annular groove 16 in which a clamping band can be axially fixed. A bleeding
- the system inside the first collar 11 comprises two circumferential grooves 17, 18 offset from one another and an axially interposed circumferential groove 19 communicating with both. This ensures a continuous gas pressure exchange between the interior of the rolling bellows and the surroundings on the assembled rolling bellows.
- the protective sleeve 14 prevents an immediate penetration of dirt into the longitudinal groove 17th
- the second collar 12 is shown rounded substantially bead-shaped outside and is thus suitable to be crimped into an annular terminal cap.
- the state of manufacture shown here is not identical to the state of use of the rolling bellows. This will be explained with reference to FIG.
- the rolling bellows of Figure 1 is shown in longitudinal section, wherein the longitudinal axis A is also shown, but peripheral edges are omitted for simplicity of illustration.
- the annular wall 13 has a first portion 13 ⁇ , which in the longitudinal half-section approximately parallel to the axis A to the first collar 11 connects and has in the longitudinal half-section inside vault.
- a second section 13 2 which adjoins the second collar 12 approximately axially parallel to the longitudinal axis A in the longitudinal half section and has outer curvature in the longitudinal half section.
- the wall is thus in the longitudinal half section substantially S-shaped with a turning point between the two sections 13 ⁇ and 13 second
- the same rolling bellows is now shown for the first time in the mounted position in the stationary state.
- the longitudinal axis A is shown, in addition, a first pin-shaped rotary body 21 and a ringkappenför- miger second rotary body 22, of which only the rolling bellows facing contour is drawn.
- a strap 23 is mounted, which tightens the first collar 11 on the shaft shaft 21.
- the free end of the protective sleeve 14 rests on the shaft journal 11.
- the first collar 11 is seated in a circumferential groove 24 of the shaft journal 21.
- the rolling bellows is everted in the region of the annular wall 13, so that it is radially considered double and the second collar 12 axially relative close to the first collar 11 outside of the first portion 13 ⁇ of the annular wall comes to rest.
- the rolling bellows in this case assumes a curvature in the longitudinal half section, which is largely continuous in one sense, wherein a turning point of the curvature in the longitudinal half section, if present, has traveled close to the second collar 12.
- a spatial body of the rolling bellows now forms a half-torus, whose smallest radius of curvature is in longitudinal section in the region of the apex 20.
- the rolling bellows is shown in the installed state under the influence of centrifugal forces.
- the second section 13 2 in this case lies largely on the inside at the second rotary body 22.
- the smallest radius of curvature is still in the area of the apex 20 and has increased in a favorable manner compared to the shape shown in representation b).
- it is now larger than in the case of rolling bellows according to the prior art.
- FIG. 1 There is shown a rolling bellows 10 according to the invention at the stage of manufacture after being formed from a mold.
- the rolling bellows is formed around a symmetrical to a longitudinal axis A.
- the rolling bellows are shown in its lowest-tension self-adjusting form.
- a first collar 11 with a smaller diameter and a second collar 12 with a larger diameter can be seen on the rolling bellows. Both are joined by a ring wall 13, widening in diameter from the first collar to the second collar, which is made in one piece with both.
- At the first collar 11 is followed by a thin-walled protective sleeve 14, whose smallest diameter is formed at its free end.
- the first collar 11 is provided for fixing on a first rotary part, in particular a drive shaft. He has a substantially inner cylindrical seat surface 15 and on the outside of an annular groove 16 in which a clamping band can be axially fixed.
- a ventilation system in the interior of the first collar 11 comprises two circumferentially offset longitudinal grooves 17, 18 and an axially intermediate circumferential groove 19 communicating therewith. This ensures a constant gas pressure exchange between the interior of the rolling bellows and the surroundings on the mounted rolling bellows.
- the protective sleeve 14 prevents an immediate penetration of dirt into the longitudinal groove 17th
- the second collar 12 is shown rounded substantially bead-shaped outside and is thus suitable to be crimped into an annular terminal cap. As will be seen below, the state of manufacture shown here is not identical to the state of use of the rolling bellows. This will be explained with reference to FIG.
- the rolling bellows of Figure 3 is shown in longitudinal section, wherein the longitudinal axis A is also shown, but peripheral edges are omitted for simplicity of illustration.
- the annular wall 13 in the longitudinal half-section approximately parallel to the axis A to the first collar 11 connects and has in the longitudinal half-section inside vault.
- the annular wall 13 joins in the longitudinal half section at an acute angle to the longitudinal axis A to the second collar 12 at.
- the wall is thus in the longitudinal half section substantially C-shaped.
- the same rolling bellows is now shown for the first time in the mounted position in the stationary state.
- the longitudinal axis A is shown, in addition, a first pin-shaped rotary body 21 and a ringkappenför- miger second rotary body 22, of which only the rolling bellows facing contour is drawn.
- a strap 23 is mounted, which tightens the first collar 11 on the shaft shaft 21.
- the free end of the protective sleeve 14 rests on the shaft journal 11.
- the first collar 11 is seated in a circumferential groove 24 of the shaft journal 21.
- the rolling bellows is inverted in the region of the annular wall 13, so that it is radially considered double and the second collar 12 is axially relatively close to the first collar 11 and a second section thirteenth 2 outside the first section 13-] of the annular wall comes to rest.
- a spatial body of the rolling bellows now forms a deformed Halbtorus whose smallest radius of curvature is in longitudinal section in the region of the apex 20.
- the rolling bellows is shown in the installed state under the influence of centrifugal forces.
- the second section 13 2 in this case is partially against the metal cap 22.
