Definitions
- the invention relates to an adapter ring which is intended for use in conjunction with rolling bearings.
- a variety of rings can be used in rolling bearings, such as circlips or sealing rings, which can also perform a different function depending on their arrangement.
- the adapter ring is not a rolling bearing ring made of bearing steel, such as a load-bearing inner or outer ring, but a ring having a secondary function.
- a usual sealing arrangement such as a cassette seal, is generally not intended to transmit axial forces as they occur during the pressing operation of the tapered roller bearing. This is due to the fact that most tapered roller bearings, which are manufactured in series, do not fall back on a Einpress perennialkeit of the bearing as a whole. Therefore, a conventional method, also described in EP 1 623 127 A1, in which the bearing rings disadvantageously have to be used separately and the bearing can not be preassembled, in particular pre-greased, can be used.
- the seal assembly is not sitting inside the outer ring but is usually used directly between the hub, usually a Gußradnabe, and Innering.
- the object of the invention is therefore to provide a cost-effective rolling bearing, in particular wheel bearing, which can be pressed in as a whole and does not have to dispense with a conventional cartridge seal.
- the object is achieved by a wheel bearing unit of the type mentioned above in that an adapter ring is used for the axial extension of the outer ring of the rolling bearing.
- the adapter ring can in this case be made of a cheaper compared to the bearing steel material, such as cold-formed sheet metal.
- the adapter ring has a hollow-cylindrical fastening piece which can be fastened to the outer ring and a hollow-cylindrical extension piece. piece for extension in the axial direction, wherein the extension piece is provided for receiving a seal assembly and / or forms the seal assembly (1 1) in part.
- the attachment piece and the extension piece can be made in one piece or even one-material.
- the attachment piece is intended to fix the adapter ring on the outer ring of the rolling bearing and the extension piece realizes the desired axial width, which is suitable for holding a seal assembly or for pressing.
- the hollow cylindrical extension piece facing away from the hollow cylindrical attachment piece, axial end on a radially inwardly directed extension.
- This extension can be provided to form a surface for the axial transmission of force, whereby force can be transmitted from the adapter ring to the outer ring during the press-fitting process, without affecting an element of the sealing arrangement.
- the said surface can also strike against a stop of the rolling bearing receiving component, in order to determine in this way the final axial position of the rolling bearing.
- an axial force must be transmitted, namely the counterforce, which is built up by the stop, which is arranged for example in a wheel hub.
- the extension itself can take different forms. For example, this may have a circumferentially continuous or interrupted ring shape. Alternatively, the extension can also be formed by one or more radially directed elements, such as a pin or a retaining claw.
- the decisive factor is that an axial surface is made available for the fastening piece in or away from the fastening piece.
- an inner axial surface of the radially inwardly directed extension is provided as a stop for the seal assembly.
- conventional sealing arrangements such as cassette gaskets, in the adapter ring and optimally positioned by the axial stop.
- the hollow cylindrical attachment piece is provided for pluggable connection with the outer ring.
- the attachment piece is glued to the outer ring or connected to this material fit.
- a pluggable connection can be made differently. It is conceivable, for example, a latching or snap connection, which goes back to a resiliently loadable part of the adapter ring, wherein this part can assume a closed position and an open position. This part can for example be a latching nose or snap hook, which can engage in a groove or recess according to the outer ring.
- the hollow cylindrical attachment piece with a cylindrical inner surface, which is provided for frictional engagement with the outer ring, in particular a press fit on the outer ring.
- the outer ring may have, in addition to an optionally already cylindrical outer surface, a further cylindrical outer surface which has a smaller radius with respect to the axis of rotation.
- An inner radius of the attachment piece can be designed such that in conjunction with the latter outer radius the outer ring a negative clearance is realized, which leads to a frictional connection over the two cylindrical surfaces when attaching the attachment piece.
- the outer ring is provided for fastening the attachment piece of the adapter ring.
- the participating in the frictional surfaces may also differ from the cylindrical shape and optionally formed conical.
- the hollow cylindrical attachment piece for at least partially, non-positive version of the outer ring is provided.
- the socket is completely in the radial direction and is realized by the hollow cylindrical attachment piece.
- a frictional connection realized only in places in the circumferential direction is possible in that the attachment piece has, for example, recesses in the axial directions, which facilitates, for example, the connection in the axial direction.
- a first outer radius of the outer ring and a second outer radius of the extension and / or attachment piece is substantially equal.
- a possible deviation of the radii does not necessarily have to lie within a production tolerance, but can be brought about by slight deviations of the nominal dimension and can amount to up to 4%, ideally 1%, based on the largest outer radius.
- the difference between the outer radii determines the extent to which the adapter ring is to be fastened within the rolling bearing receptacle.
- the outer radius of the adapter ring can be selected to be slightly smaller than the largest outer radius of the outer ring.
- the outer ring has an inner race for tapered rollers, balls, ball rollers or similar rolling elements, whereby the adapter ring for all so-called insert bearings that can be pressed in the whole, regardless of the rolling element used, can be used.
- This insert solution includes a holding element, which holds the inner ring 2 and the outer ring 1 axially to each other or axially fixed to each other, so that the camp can not fall apart during transport and can be pre-installed by the manufacturer.
- Fig. 1 is a single-row tapered roller bearing with a first outer ring attached to the adapter ring
- Fig. 2 is a single-row tapered roller bearing with a second outer ring attached to the adapter ring.
- FIG. 1 shows a single-row tapered roller bearing with a first adapter ring 17 fastened to the outer ring 1.
- the adapter ring 17 consists of a fastening piece 7, an extension piece 6, a radially extended extension 8 and is attached to the outer ring 1 in a force-fit manner.
- the outer ring 1 has been pressed together with the plugged adapter ring 17 in a cast wheel hub 3 of a commercial vehicle. Due to different inner radii of the wheel hub of the adapter ring 17 abuts axially with the outer surface of the radially inwardly directed extension 8 on the wheel hub 3. Together with the outer ring 1, the other components of the tapered roller bearing can be pressed in as a whole.
- the inner ring 2 is equally pressed onto an inner part, such as a journal 4.
- the seal assembly 9 is applied at any time with axial forces.
- the seal assembly 9 is formed in Fig. 1 with a single support plate and two attached thereto, radial sealing lips.
- this can be carried out in several parts, such as a cassette seal.
- the decisive factor is that no axial forces during the press-fitting process can impair the functioning of the sealing arrangement 9. It may happen that in the installation of conventional rolling bearing sealing lips slip off their corresponding sealing surfaces and are folded in the worst case, so that the required sealing effect does not occur. This is particularly problematic because the seal assembly after the pressing in the rule is not readily visible, or can not be checked for correct lip position.
- the adapter ring 17 acts in the radial direction as a seal assembly, because the interior of the tapered roller bearing is shielded.
- the recess 10 on the outer ring 1 has an axial annular surface and a cylindrical surface, wherein the cylindrical surface is provided for adhesion with the attachment piece 7.
- the axial annular surface of the recess 10 serves as a stop and for axial power transmission during the pressing process.
- a connection between the adapter ring 17 and the outer ring 1 can be ensured by a variety of connection options.
- various solutions by means of a positive connection or a combination are conceivable.
- a positive connection can be produced, for example, by elastic elements which have a nose shape or a hook shape and can assume both a closed position and an open position.
- Fig. 2 shows a single-row tapered roller bearing with a second attached to the outer ring 1 adapter ring 1 first Adapter ring 1 1 is attached by means of a recess 16 to its attachment piece 15 on the outer ring 1.
- the axial annular surface of the recess 10 of the outer ring 1 is used for axial force transmission, but the axial outer surface of the outer ring 1, which is arranged axially approximately at the end of the attachment piece 15 or at the beginning of the extension piece 12, wherein both pieces 15, 12th merge material into each other.
- the adapter ring 1 1 has a radially inwardly directed extension 13, which is continuous in the circumferential direction and with respect to a cylindrical surface of the inner ring 2 with an end piece 14 closes and thus forms an annular sealing gap between the inner ring 2 and the end piece 14 , As a result, the adapter ring 1 1 partially forms a seal arrangement, which may optionally also include radial or axial sealing lips.
- the tail is made for example of rubber or other elastic material, which is used as a sealing material on the sliding sealing contact on the inner ring 2.
- the invention relates to an adapter ring for rolling bearings, in particular wheel bearings, which is provided to relieve seal assemblies during the press-fitting process of the preassembled rolling bearing.
- the popular insert function of the bearing does not have to be waived, but at the same time expensive bearing steel can be saved, as the Outer ring of the bearing can be formed with a smaller width.
- the adapter ring on a provided for attachment to the outer ring hollow cylindrical attachment piece and a hollow cylindrical extension piece, wherein the extension piece is provided for receiving a seal assembly and / or forms the seal assembly in part.
