Definitions
- the invention relates to a double-sided loadable multi-row Schrägkugella ⁇ ger, which has a main bearing for supporting the main load with at least two Ku ⁇ gelkränzen, which is assigned to set an axial preload a preload bearing with at least one ball race with opposite pressure angle.
- FIG. 18 of this document shows the mounting of a bevel pinion shaft for a transfer case of a motor vehicle.
- the bearing is designed in three rows with a one-piece bearing outer ring and a two-part positional inner ring, the bearing inner rings having one or two shoulders. This makes it possible to easily mount the bearing by the bearing inner rings are pushed on both sides in the axial direction from outside to inside on the ball races.
- the one-piece bearing outer ring has raceway grooves in which the ball races are arranged.
- the Haupt ⁇ the forces of the bevel pinion shaft receiving main bearing is formed in two rows, while the associated preload bearing is single row.
- the adjustment of the bias voltage is such that the inner ring of the preload bearing is moved in the axial direction by an actuator on the main bearing.
- the two part bearings are arranged at an opposite pressure angle to one another, ie, the ball pressure lines of both bearings each extend obliquely from the inside to the outside.
- the disadvantage here is, on the one hand, that during storage the storage arrangement can disintegrate into its individual components. Since, however, as a rule the individual bearing components are assigned to one another, this can lead to problems if a large number of ball bearings is accommodated in a packaging unit. On the other hand, it is disadvantageous that these angular contact ball bearings are made solid and require a larger radial space due to their expansion.
- the expert is also known in this context that the machining of bearing rings is relatively complex and thus teu ⁇ er.
- the invention is therefore based on the object to develop a generic Wälzla- ger so that its cohesion is improved and that it can be easier to manufacture.
- this object is achieved by the characterizing part of claim 1 in conjunction with the preamble in that a bearing gerinnenring of two spaced apart by a gap partial rings is formed, the partial ring and a bearing outer ring of the main bearing depending on the ball races separating in the radial Direction opposite first shoulder and each have a at one outer and one inner end diametrically opposed second shoulder, wherein at least one of the bearing rings is made of a bearing steel by a non-cutting shaping process.
- This arrangement of the shoulders on the bearing rings of the main bearing ensures that this can not disintegrate in the axial direction.
- Another advantage lies in the non-cutting production of the bearing rings, since they can be manufactured substantially simpler in terms of their production. Taking into account the available installation space, the most varied variants of bearing rings can be produced without cutting, which can also be implemented in simple fashion. rather adaptable to the respective connection construction. Also, space is saved by their small radial expansion. It is also advantageous that weight can be saved due to the lower mass of the non-cutting bearing rings.
- the ball raceways of the main bearing have the same or a different diameter.
- the ball races of the preload bearing should have the same or a larger diameter than the ball raceways of the main bearing.
- the bearing balls of the preload bearing have a same or a smaller diameter than the bearing balls of the main bearing.
- the bearing outer ring should be integrally formed. A further variant of the invention is described in claim 6. Thereafter, the bearing outer ring should be formed in two pieces and be encompassed by a sleeve surrounding its circumferential surface.
- the outer ring is reinforced by a radial doubling, which is extended in the axial direction and forms an outer raceway for the preload bearing.
- the ball bearing is designed as a captive assembly, wherein at least one of the ball rings of the bearing inner ring and / or the bearing outer ring of Vorspan ⁇ mbislagers verlier ⁇ safely held by a running in the circumferential direction Schnier ⁇ is. From claim 9 it is apparent that the ball bearing is designed as a captive assembly, wherein at least one of the Kugel ⁇ wreaths of the bearing inner ring and / or the bearing outer ring of the main bearing is held captive by a running in the circumferential direction Schnapplace.
- the bearing rings are subjected to a heat treatment process for increasing the hardness.
- a through-hardening or a Case hardening of the bearing rings As an advantageous method, in particular the low-distortion laser hardening or induction hardening offer here.
- this ball bearing should be used for supporting a shaft in a change-speed gearbox for a motor vehicle or for supporting a bevel pinion shaft in a Achsverteilergetriebe.
- the ball raceways of the main bearing and / or the preload bearing are provided with a hard material coating.
- a hard material coating cause a high surface hardness and thus increase the wear resistance.
- the hard material layer also causes a reduction of the friction, whereby the friction conditions are almost constant over the entire service life of the layer.
- Suitable hard coatings are, for example, modified carbon layers (diamond-like carbon) or nitrides of titanium and niobium, which are distinguished by high hardness, high wear resistance and low-friction properties, in particular improving the emergency running properties of the bearing in the event of insufficient lubrication.
- Figures 1 to 10 show different embodiments of the invention Phyg in longitudinal section.
- the illustrated in Figure 1 and provided with the reference numeral 1 three-row angular contact ball bearings consists of the main bearing 2 and the Vorwoodsla ⁇ ger 3 together.
- Main bearing because it has to take the axial forces shown in the arrow direction, which are greater than in the reverse axial direction.
- Preload bearings because with the help of the bias the total angular contact ball bearing 1 is set.
- the bearing outer ring 4 is formed ein ⁇ part and is provided in the region of the main bearing 2 with the radially inwardly directed first shoulder 4.1, which separates the rows of balls 9, 10 voneinan ⁇ . To the left of this follows the second shoulder 4.2, which separates the rows of balls 10, 11 from each other.
- the bearing inner ring 5 is formed in two parts and consists of the partial ring 5.3, which is assigned to the main bearing 2 and the partial ring 5.4, which belongs to the preload bearing 3. Both partial rings 5.3, 5.4 are spaced apart in the axial direction by the gap s. The targeted preselection of the gap s ensures that after installation and axial clamping of the partial rings 5.3, 5.4, a bearing tolerance lying in the narrow tolerance range can be set, wherein the gap s can drop to a value of zero.
- the partial ring 5.3 has in its center the radially outwardly directed first shoulder 5.1, which faces the shoulder 4.1.
- the second shoulder 5.2 which separates the rows of balls 9, 10 from each other and the second shoulder 4.2 of the Lager ⁇ outer ring is diametrically opposite.
- the main bearing 2 and the preload bearing 3 have an opposite pressure angle, ie, they are set to each other in the O position, as indicated by the associated ball pressure lines.
- the angular contact ball bearing 1 is arranged in the housing 12 for supporting the shaft 13. The bearing preload is now set such that the Detail ⁇ ring 5.4 of the inner ring 5 is moved in the axial direction to the right.
- the figure further shows that such a bearing can be mounted in a simple manner. This takes place in such a way that the partial ring 5.3, which at the same time carries the row of balls 9, is inserted from right to left until its shoulder 5.1 comes into contact with the crown ring 10, which in turn is supported by the bearing outer ring 4.
- the preload bearing 3 is completed by pushing the partial ring 5.4 in the direction of the partial ring 5.3.
- the partial ring 5.3 is in the region of Kugel ⁇ wreath 10 with the Schnapplace 5.3.1 and in the ball ring 11 are the bearing outer ring 4 with the snap stage 4.3 and the partial ring 5.4 with the snap stage 5.4 .1 provided.
- the bearing arrangement shown in FIG. 2 differs from that in FIG. 1 only in that the raceways of the bearing balls 11 of the preload bearing 3 have a larger diameter than the raceways of the bearing balls 9, 10 of the main bearing 2. This is achieved in that the La geraus touchring 4 is provided following its shoulder 4.2 with a radial extension 4.4, which merges into the shoulder 4.5.
- the bearing arrangement shown in FIGS. 3 and 4 is distinguished by the fact that the bearing balls 11 of the preload bearing 3 have a smaller diameter than the bearing balls 9, 10 of the main bearing 2 and opposite ball raceways of larger diameter.
- Both bearing rings 4, 5 are formed as thin-walled produced without cutting, wherein according to Figure 4, the axial distance between the main bearing 2 and preload bearing 3 is magnö ⁇ ßert. Between the partial rings 5.3, 5.4, in turn, the gap s is arranged to set the bearing preload.
- the bearing assembly shown in Figures 5 and 6 is characterized in that the bearing outer ring 4 of the main bearing 2 is reinforced by a double 4.6, which extends over the entire raceway range of the bearing balls 9, 10. This doubling 4.6 is extended in the axial direction over the shoulder 4.5 and thus forms the raceway for the bearing balls 11 of the preload bearing 3.
- the bearing preload is adjusted via the gap s between the two partial rings 5.3, 5.4.
- bearing variants according to the invention are shown, in which the bearing outer ring 4 is formed in two pieces and is enclosed by a sleeve 14 comprising its circumferential surface.
- the preload bearing 3 is of double-row configuration, wherein the partial ring 5.4 is provided with the shoulder 5.4.3 arranged centrally and the shoulder 5.4.2 arranged on the left side thereof.
- the associated bearing outer ring 4.7 has the centrally arranged shoulder 4.7.1 and the right side arranged therefrom shoulder 4.7.2, which is the shoulder 5.4.2 diametrically opposite.
- Main bearing 2 and preload bearings 3 are spaced apart in the axial direction, with either the plastically deformable sleeve 15 or the spacer ring 16 being arranged between them.
- Both Hauptla ⁇ ger 2 and preload 3 are enclosed by the sleeve 14, which engages either at the right-hand outer end in the housing 12 or the bearing outer ring 4 engages behind on its end face.
- the gap s required for setting the bearing preload is determined in the upper part of the figure by the distance between the partial rings 5.3, 5.4, wherein after the preload has been reached, the gap between the sleeve 15 arranged radially is deformed radially outward. In the lower part of the picture, the gap s required for adjusting the pretensioning is present between the spacer ring 16 and the partial ring 5.3.
- both the main bearing 2 and the preload bearing 3 are provided with the same diameter and are surrounded by the sleeve 14, wherein the distance between the outer bearing rings 4 and 4.7 is set by an indentation 14.1 of the sleeve 14.
- the sub-rings 5.3, 5.4 are, as shown in the upper part of the picture, either almost to each other or, as shown in the lower part of the image, separated by the spacer ring 16, wherein the required for adjusting the bias gap s zwi ⁇ tween the two sub-rings 5.3, 5.4 or between partial ring 5.4 and spacer ring 16 is arranged.
- the bearing arrangement shown in FIG. 9 is distinguished from that shown in FIG. 8 in that the indentation 14. 1 is dispensed with in the case of the sleeve 14. As can be seen, the gap s between the partial rings 5.3, 5.4 and in the lower part of the picture between the partial ring 5.4 and the spacer ring 16 is formed in the upper part of the picture.
