Definitions

• Cylindrical roller bearing or needle roller bearing executed.
• German Patent Application DE 19726726 A1 can be mentioned here. While the cited patent publication still shows an axial stop in the drive bearing, which avoids an axial sliding out of the cylindrical roller bearing, it was found that pushed out in modified versions with a smooth continuous cylindrical bore in the drive bearing for receiving the cylindrical roller bearing in rare cases this camp from the drive end plate can be. This pushing out is caused by acting between the drive shaft and the rolling friction when pushing out the drive shaft.
• the erf ⁇ ndungsdorfe launcher having the features of the main claim has the advantage that in the drive end shield further a cylindrical smooth, step-free bore for receiving the bearing can be provided and at the same time a sliding out of the bearing is reliably prevented from the drive bearing.
• a non-cutting production process can be used in the production of rolling bearings, which is much less expensive than the machining process on the drive end plate.
• Figure 3 is a fragmentary view of a rolling bearing according to a second embodiment.
• freely ejecting starter 10 for starting internal combustion engines in motor vehicles has a front drive bearing plate 11, in the bearing bore 12, a roller bearing 13 is used to receive a drive shaft 14.
• the drive shaft 14 enters at the front end
• the drive shaft 14 carries at the rear end of a freewheel 16 and a meshing mechanism 17 which is to be actuated via a push-in lever 18 by a starter relay 19.
• the drive shaft 14 is rotatably mounted with its Einspurmechanismus 17 on an output shaft 20 of the starting device and axially displaceable.
• a planetary gear 21 At the rear end of the drive shaft 20 sits a planetary gear 21, on the drive side, a sun gear 22 engages, which is arranged on the rotor shaft 23 of a starter motor 24.
• the planetary gear 21 is received in the housing 26 of the drive motor 24 via an elastic intermediate bearing 25.
• FIG 2 the front portion of the drive bearing plate 11 is shown in a cutaway longitudinal section.
• a roller bearing 13 designed as a roller bearing is inserted in the bearing bore 12.
• This rolling bearing 13 has an outer ring 30, via which the rolling bearing 13 is firmly seated in the drive bearing plate 11.
• This outer ring 30 has a collar 33, a Moving the roller bearing 13 from the drive end plate 11 prevented out.
• This collar 33 is formed in this exemplary embodiment as a circumferential bead.
• a starting device for internal combustion engines which has a drive bearing plate 11 and a drive shaft 14, wherein the drive shaft 14 in the
• Anti-disc bearing 11 is supported by a roller bearing 13 and the rolling bearing 13 allows a relative movement between the drive shaft 14 and the roller bearing 13. Incidentally, the relative movement is both in the drive shaft direction and in the circumferential direction.
• the rolling bearing 13 has an outer ring 30 which is stuck in the drive end plate 11. This outer ring 30 has a stop 33, which is a displacement of the
• the outer ring 30 has a cylindrical contour over which the rolling bearing 13 is fitted in the drive end plate 11.
• the stopper 33 is disposed at the axial end of the rolling bearing 13, which is directed toward the interior of the starting device 10.
• Stop 33 projects beyond the cylindrical contour of the outer ring 30 and is embodied here in one piece with the outer ring 30 and can also be referred to here as a collar 34 or bead.
• the collar 34 is not designed as a ring-like bead, as is the case in Figure 2. Instead, a plurality of projections 36 are provided on the circumference of the outer ring 30, which are preferably distributed uniformly on the circumference of the outer ring 30. For example, three projections 36 are distributed at an angular distance of 120 °.
• Figure 3 The illustrated in Figure 3
• Projection 36 is produced in that in the transition region from the cylindrical contour of the outer ring 30 to the axial collar 39 of the outer ring 30 in the axial direction a a stamp has deformed a part of this transition region such that the projection 36 is formed.
• the rolling bearing 13 is a cylindrical roller bearing, preferably a needle bearing, with a tinny outer ring 30, the projection 36 or collar 34 is integrally formed.
