One-way clutch

The innovation relates to a one-way clutch with an adjacent roller bearing for supporting a shaft. One Such an arrangement is often combined into a structural unit and referred to as a mounted freewheel.

; a mounted freewheel is already known in which a sleeve on its inner surface both the KLIemmflachen for the overrunning clutch, as well as the Carrying tracks for the rolling bearings arranged next to it on both sides. The career of the eimm rolling bearing has it a smaller diameter than the raceway of the other rolling bearing, while the clamping surfaces for the overrunning clutch are on an intermediate diameter. This graduated diameter determines the length of use of rolling elements of different diameters for the two rows of rolling elements. This makes storage expensive.

The task of the innovation is therefore to create a structural unit for a © overrunning clutch with a roller bearing arranged next to it, in which standard components can be used to the greatest possible extent, for example standard overrunning clutches and standard rolling bearing cages fitted with rolling elements of common dimensions. This task will be renewed. :.?. ^ z ..: ~: 'c - I, "3t that the overrunning clutch has an economical gei ^ rt-gtc :. outer ring, which in turn is in a syanl: - £ ■ manufactured sleeve

is arranged, the bore of which is used as a raceway for the rolling elements of the rolling bearing arranged next to the overrunning clutch serves.

The freewheel bearing according to the innovation only requires a non-cutting sleeve as a special component. The rest Components can be series components. This will make warehousing considerably simplified and enables economical production.

An embodiment of the innovation provides that the non-cutting sleeve in the area of the rolling element tracks has a larger inner diameter than in the area in which the outer ring of the overrunning clutch is arranged. Because of the smaller diameter of the sleeve in the area of the outer ring of the overrunning clutch can when the When freewheeling, the raceway for the roller bearing arranged next to it is not damaged. If on both sides of the overrunning clutch Rolling bearings are to be arranged, so you can have the same diameter for the two rolling element raceways and thus enable the use of rolling elements of the same size. This is a particular advantage over the above-mentioned known overrunning clutch with storage, in which the raceways for the two rows of rolling elements have different diameters.

Two embodiments of the innovation are shown in the drawing and are described in more detail below. It demonstrate:

Figure 1 shows a mounted freewheel in a continuously smooth thin-walled sleeve,

FIG. 2 shows a mounted freewheel in a thin-walled sleeve, which in the area of the rolling element raceway has a Has a larger diameter than in the area in which the outer ring of the overrunning clutch is arranged is.

The arrangement of Figure 1 consists of a ^ reilai f coupling 1 and roller bearings 2 and 3 arranged next to it on both sides. The non-cutting outer ring 4 of the overrunning clutch is in the non-cutting sleeve 5 f

pressed in, the rims 6 and 7 are folded after the insertion of the two bearings and so the individual Combine elements into one unit.

In the arrangement of Figure 2, the thin-walled sleeve in its central area associated with the outer ring 9 of the overrunning clutch has a smaller diameter than in the area of the raceways of the two rolling bearings 10 and 11. The raceways for the two rows of rolling elements have the same diameter, so that Rolling elements of the same size can be used in both rows of rolling elements.

The innovation is by no means restricted to the illustrated embodiments of overrunning clutches and roller bearings. Rather, all known types of overrunning clutches and roller bearings can be used. It is also possible to provide only a single row of rolling elements if the application allows this.

Claims (2)

INDUSTRIEWERK SCHAEFFLER OHG HERZOGENAURACH at K1URNBERG G 1362 Pt-Gu / ha protection claims 1. Overrunning clutch with roller bearing arranged next to it "' for mounting a shaft, characterized in that the overrunning clutch has a non-cutting outer ring which is in turn arranged in a non-cutting sleeve, the bore of which serves as a raceway for the rolling elements of the rolling bearing arranged next to the overrunning clutch. 2. Overrunning clutch according to claim 1, characterized in that that the non-cutting sleeve has a larger inner diameter in the area of the rolling element raceways than in the area in which the outer ring of the overrunning clutch is arranged.
