Definitions
- the present invention relates to a sealing arrangement for a pedal crankshaft of an e-bike. Furthermore, the invention relates to a seal for this seal assembly. Finally, the invention relates to a pedal crank assembly, in particular for an e-bike or pedelec, which uses this seal arrangement.
- seals are used for sealing rolling bearings, in particular of rolling elements between two rotatable bearing rings.
- the seals are intended to protect the bearing from external environmental influences, such as dirt and water, thus ensuring correct operation and a long service life.
- a seal arrangement for a bearing is described.
- the bearing consists of a first and a relative to this rotatable second bearing ring, wherein on the first bearing ring, a circumferential seal is arranged and the second bearing ring has a sealing surface.
- the seal has at least two sealing lips, which bear sealingly against the sealing surface of the second bearing ring.
- a rolling bearing act on this different strong, differently oriented and temporally different forces. For example, in an e-bike, pedelec or in an electrically assisted bicycle, rotating forces occur due to the crank movement of the pedals.
- Rolling bearings on bicycle cranks have a small dimensioning, so that correspondingly small bearing seals are used, whose installation is difficult and whose sealing contact is in the pm range.
- a wrong installation of the bearing seal means a gap between seal and component can penetrate through the dirty water. This happens even if the sealing lip is not sealing.
- Ring seals are arranged to seal a space between a housing and the bearing ring on the outer bearing ring surface. Also the ring seal does not seal sufficiently. At the bearing surface of the ring seal corrosion is often detectable by penetrating dirty water. Greater ring seal diameters or expansions, which could increase the seal, can damage the seal or shift the position of the housing relative to the bearing race.
- the object is achieved by a sealing arrangement according to the appended claim 1, by a seal according to the independent claim 9 and by a pedal crank arrangement according to claim 10.
- the sealing arrangement comprises a rolling bearing consisting of an outer ring and an inner ring which can be rotated relative to the latter about a common axis, and rolling elements arranged between the two bearing rings for unrolling the two bearing rings. Furthermore, the sealing arrangement comprises a housing at least partially surrounding the outer ring, a sealing ring and an elastomer seal.
- the seal assembly serves to seal a space between the outer ring and the inner ring, and in addition the sealing of a space between the housing and the outer ring.
- the sealing ring is arranged in a groove of the outer ring. The groove is formed on the radially outer surface of the outer ring. The sealing ring rests against the housing.
- the second seal namely the elastomeric seal is arranged radially between the inner ring and the outer ring.
- the elastomer seal has a disk-shaped seal body. On the inner circumference of the sealing body, a sealing lip is formed, which bears sealingly against the inner ring. With its outer circumference, the elastomer seal is against rotation on the outer ring.
- On a side surface of the seal body at least two projections are formed circumferentially. The two projections extend axially and are sealingly and force-absorbing on the housing. The two projections have a supporting effect and ensure the contact of the sealing lip on the inner ring in order to prevent the penetration of For example, to prevent dirty water in the space between the housing and outer ring.
- the at least two protrusions are formed on the side surface of the seal body as two concentric circles.
- the elastomeric seal has three protrusions disposed on the side surface of the seal body as concentric circles. In an alternative embodiment, the elastomeric seal has five protrusions disposed on the side surface of the seal body as concentric circles.
- At least two sealing lips are formed on the inner periphery of the sealing body of the elastomeric seal, which bear sealingly against the inner ring.
- the at least two, in particular two, sealing lips are preferably formed at opposite angles.
- the at least two sealing lips are preferably designed such that they are angled in opposite directions, so that together they form a V.
- the sealing body preferably has an increase in volume on its outer circumference, which forms a clamping bead.
- the sealing body is preferably arranged non-rotatably on the outer ring.
- the sealing body is arranged non-rotatably by means of the clamping bead in a second groove of the outer ring.
- the sealing body of the elastomeric seal is preferably formed angled on the inner circumference and on the outer circumference.
- the inner circumference and the outer circumference of the sealing body are angled in the same axial direction.
- the inner circumference and the outer circumference of the sealing body are angled in the same axial direction opposite to the alignment of the projections of the sealing body, so that a force path from the projections adjacent to the housing along the sealing ment body to the inner circumference and outer circumference, in particular its sealing lip, forming, whereby the concern of the sealing lip is secured to the inner ring.
- the formation of the elastomeric seal with the two projections, which bear against the housing and form a force path through the sealing body towards at least one sealing lip, has proven to be advantageous since the lifting of the sealing lips is prevented. Another advantage is that existing distances between sealing lips, seal and bearing rings and housing are eliminated during assembly of the assembly. It is also particularly advantageous that the penetration of dirty water is prevented.
- the elastomeric seal in particular in the region of the sealing lips, one or more spring elements can be arranged, which support the sealing of the elastomeric seal and prevent the lifting of this.
- the elastomeric seal has a reinforcement that is at least partially surrounded by the elastomer and that serves to ensure the stability of the seal.
- the sealing ring serves to seal the space between the housing and the outer ring and to some extent also the damping mounting of the housing relative to the outer ring.
- the sealing ring is also made of an elastomer.
- the sealing ring is selected according to the height and the width of the groove in which it is arranged.
- the groove is preferably formed on the outer ring decentralized on the side surface circumferentially.
- the sealing ring corresponds in its basic form to a so-called O-ring.
- the sealing arrangement can be installed in a motor or drive of an electric bicycle, e-bike or pedelec.
- the inner ring arranged on a shaft of the e-bike engine and rotates with this, in particular on a pedal crankshaft of an e-bike, which is surrounded by at least two camps.
- the two bearing rings are pressed together with the rolling elements and the two seals on the shaft and are then surrounded by the housing of the motor.
- the bearings thus formed can be, for example, ball roller bearings or cylindrical roller bearings, depending on the rolling element type.
- the seal according to the invention corresponds to the previously described elastomer seal with all described embodiments.
- the seal is preferably used in the sealing arrangement described above.
