Abstract
A method for forming an end-side toothing arrangement of a rolling bearing, in particular a wheel bearing. In a first method step, before the reshaping of an end piece of a hub, a die is axially arranged on the rolling hearing in a preassembled state and, in a second method step during the reshaping of the end piece and the shaping of the end-side toothing arrangement, the die radially delimits a radial recess of the rolling rivet collar as it forms. In addition, the die reduces or prevents radial widening of the inner ring.
Description
- The invention relates to a method for forming an end-side toothing arrangement from a rolling rivet collar of a rolling bearing, in particular a wheel bearing. The invention further relates to a rolling bearing, or wheel bearing, with a correspondingly molded-on end-side toothing arrangement.
- A method of this type is used in particular in the automotive field in the manufacture of wheel bearings.
- In the past, it has been found that a wheel bearing, but also other rolling bearings with a rolling rivet collar, can advantageously be connected to the driving element of the drive train via an end-side toothing arrangement in order to save installation space or to avoid problems of fitting a radial toothing arrangement.
- A method for reshaping an end piece of a wheel hub is known from US 20010046339 A1, the end piece being reshaped into a rolling rivet collar. While the rolling rivet collar is shaped by what is known as a rivet header, unnecessary widening of the inner ring is prevented in that the inner ring is radially supported from the outside inwards by a support.
- The end piece of a wheel hub may be axially and radially deformed by means of the rivet heading method. This involves the formation of teeth which are oriented in the axial direction and form a toothing arrangement circle around the axis of rotation. A method of this type and also a corresponding wheel bearing with a rolling rivet collar having teeth on the end side emerge from WO 2006105748 A1.
- The tooth depth of the end-side toothing arrangement is a crucial variable in the axial transmission of high torques. The greater the tooth depth is, the greater the maximum torque to be transmitted is. However, the limits of the rivet heading method become apparent when a large number of thin teeth having a large tooth depth have to be produced. On account of the wobbling motion of the rivet header, although a tooth well can be actively shaped, the tip of the tooth can be shaped only with difficulty, as the direction of material flow is opposed to the action of force and the rolling rivet collar to be shaped opposes enlargement of its surface area.
- Furthermore, it has in practice been found that the rivet heading method often leads to an unevenly shaped end-side toothing arrangement in which the engagement with the mating toothing arrangement does not always have a sufficiently precise fit for uniform torque transmission.
- The invention is based on the object of specifying a method for forming an end-side toothing arrangement and a rolling bearing with an end-side toothing arrangement, in which the aforementioned drawbacks are avoided.
- This object is achieved by a method having the features specified in claim 1.
- Furthermore, this object is achieved by a rolling bearing having the features specified in claim 6.
- The method according to the invention for forming an end-side toothing arrangement from a rolling rivet collar of a rolling bearing, in particular a wheel bearing, includes at least the following steps:
- a) In a first step, before the final reshaping of an end piece of the hub of the rolling bearing, for example after a shaping pretreatment of the end piece (what is known as flaring), or on the end piece, which has not been pretreated, a die is axially arranged on the rolling bearing in a preassembled state. The end piece may for example be the hollow cylindrical end of a wheel hub which the rivet header is intended to deform both axially and radially. The hub of the rolling bearing is the rotating part of the rolling bearing onto which the wheel flange is molded in the case of the wheel bearing.
- The term “preassembled state” means in this connection that the hub, the inner ring or rings, the outer ring or rings and also the rolling bodies are already arranged relative to one another in an operational manner and are ultimately to be united by cold reshaping of the rolling rivet collar to form a rolling bearing unit.
- b) In a second step during the reshaping of the end piece of the hub and the simultaneous shaping of the end-side toothing arrangement, the die delimits a radial expansion of the rolling rivet collar as it forms. In this case, the rolling bearing unit is pretensioned for axially securing the inner ring by the rolling rivet collar as it forms.
- The die is an instrument which is used in a template-like manner in the sense of a delimitation in order to restrict radial expansion during the cold reshaping. As a result, the material flow of the rolling rivet collar is diverted in an intensified manner in the axial direction during the cold reshaping. The shaping by the rivet header, the force exerted by which is opposed to the flow of material, is thus much more effective. The teeth of the end-side toothing arrangement can be shaped more precisely. Even shapes which cannot be achieved without a die, for example a greater axial tooth height, are possible.
- Advantageously, the die shapes an axial and/or radial outer face of the rolling rivet collar. In addition to the function of the radial delimitation by the die, the die can also be used for shaping the rolling rivet collar. This may for example be the case on the cylindrical outer face, or else in an axial outer face of the rolling rivet collar. It is thus possible to achieve very extensive design freedom and to use this freedom advantageously for a desired shape of the rolling rivet collar. The die and the rivet header can interact in such a way that the desired material flow occurs. The result becomes all the more dimensionally precise when the die and the rivet header can be used to control any possible spread of the loss of material and the deformation pressure acting on the rolling rivet collar as it forms is increased.
- Advantageously, an inner extension of the die shapes and delimits the radial outer face of the rolling rivet collar. If the inner extension is used as a delimiting element, it is beneficial to provide various inner extensions for various predefined shapes of the rolling rivet collar, wherein the inner extensions can be inserted into the die.
- Advantageously, a clamping ring radially supports the inner ring of the rolling bearing from the outside inwards during the reshaping (second step). A clamping ring of this type prevents the disadvantageous widening of the inner ring in the radial direction during the rivet heading.
- Advantageously, the clamping ring is fastened to the die or is integrally connected thereto. A one-piece embodiment also allows the radial supporting of the inner ring to be at the same time ensured in one operation, that is to say when arranging the die on the preassembled rolling bearing.
- The rolling bearing according to the invention, in particular a wheel bearing, with a rolling rivet collar with a molded-on end-side toothing arrangement, wherein the rolling rivet collar has been radially delimited and/or shaped on a radial outer face during the formation of the rolling rivet collar, displays a uniform toothing arrangement formation and can be used, owing to an optimized toothing arrangement depth, for transmission of a high torque.
- Advantageously, the outer face of the rolling rivet collar is shaped annularly, conically or in a similar manner during the rolling riveting process. The rolling rivet collar can then be shaped in an advantageous manner for the rolling bearing: for example, in such a way that the rolling rivet collar supports the sealing function of a sealing arrangement or forms a sealing gap with another component, for example a joint bell.
- Advantageously, the outer face of the rolling rivet collar has a circumferentially continuing, in particular repeating, embossment. This allows the rolling rivet collar to be used, for example, to attach information, for example for manufacturer information, serial numbers, specifications, or product labeling.
- Advantageously, the circumferentially continuing embossment is embodied as an encoder. This fulfills a component integration which is very efficient in terms of manufacture and leads to a stable transmitter wheel. Normally, encoders have to be used as a separate component requiring a separate manufacturing step. This step is now no longer necessary. In addition, the encoder cannot move axially away from the sensor of a rotational speed measuring device. This ensures a very reliable measurement of rotational speed.
- Advantageously, the outer face of the rolling rivet collar is provided at least in part as a seat for an encoder or a sealing element. The outer face may be configured in such a way that it is optimal for the component in question. This may for example be ensured in a force-transmitting manner by a substantially smooth outer face or else in a form-fitting manner by an outer face with elements engaging with the component in question.
- Further advantageous formations and preferred developments of the invention may be inferred from the description of the figures and/or the sub-claims.
- In the drawings:
-
FIG. 1 is a longitudinal section of a preassembled wheel bearing unit with the die before the rolling riveting process; and -
FIG. 2 is a longitudinal section of a preassembled wheel bearing unit with the die after the rolling riveting process. -
FIG. 1 is a longitudinal section of a third-generation preassembled wheel bearing unit with adie 5 before the rolling riveting process in a first step of the method for forming an end-side toothing arrangement. - The deformable,
cylindrical end piece 9 of thewheel hub 2 is to be cold reshaped in the pending rolling riveting process. For this purpose, thedie 5 is arranged on the preassembled wheel bearing unit in such a way that amolding face 8 of the inner extension 7 can be used for radially delimiting and shaping the rolling rivet collar. Themolding face 8 is cylindrical, allowing a likewise cylindrical shape to be imparted to the rolling rivet collar. However, themolding face 8 could also be configured conically for the purpose of better shaping. - The inner extension 7 is designed in one piece with the
die 5, so that the method can be kept easy to carry out. - Advantageously, the clamping ring 6 is also formed in one piece with the
die 5 and conically embodied on the radially inner side. The conicity establishes the radial supporting of theinner ring 4 in such a way that an increased axial pretensioning force (in the direction indicated by the arrow) also allows the radial supporting force to be regulated. - Advantageously, the outer ring 1 and the rolling bodies of the
rows 3 of rolling bodies are not included in the transmission of force, so that these parts cannot become damaged during the rolling riveting process. - Alternatively, the
molding face 8 can display all possible desired shapes which can be impressed on the rolling rivet collar. In addition, the radial run-out of the end-side toothing arrangement is improved on account of the centering of thedie 5 by means of theinner ring 4. -
FIG. 2 is a longitudinal section of a preassembled wheel bearing unit with thedie 5 after the rolling riveting process. - After the cold reshaping, the formation of the end-
side toothing arrangement 10 is completed. The radialouter face 11 of the rollingrivet collar 12 has assumed the cylindrical shape of the molding face 8 (denoted inFIG. 1 ). - The
die 5 can now be removed in the axial direction, as the rollingrivet collar 12 maintains the pretensioning of the rolling bodies via the bearing rings 1, 4 and thewheel hub 2. - In summary, the invention relates to a method for forming an end-side toothing arrangement of a rolling bearing, in particular a wheel bearing. The aim is to improve the uniformity of the end-side toothing arrangement and to allow a greater tooth depth. This is achieved by two method steps in that, in a first step before the reshaping of an end piece of a hub, a die is axially arranged on the rolling bearing in a preassembled state and, in a second step during the reshaping of the end piece and the shaping of the end-side toothing arrangement, the die radially delimits a radial expansion of the rolling rivet collar as it forms. In addition, the die reduces or prevents radial widening of the inner ring.
