with external contact flange

The invention relates to rolling bearings, in particular needle bearings, with a cylindrical bearing sleeve forming the outer race with two inwardly directed axial movement the niälzkörper limiting splash and one in the Check out one of these two flanges, which are arranged outwards Flange that serves as a stop for the bearing.

With such a design of the bearing sleeve, it is further proposed according to the invention that the vVälzkörper designed as needle rollers which are tapered at their ends Pührungszapfen run out, which overlapped by the lips and held captive, allow radial and axial play of the needle rollers.

The purpose of the invention is the known bearing sleeves of this Kind of improve. For this purpose it is proposed according to the invention that at the inner edges of the radially inward directed flanges axially inwardly projecting, sicn over the circumference of the planche extending lips are provided are. These lips give the bearing sleeve a more perfect finish and form together with the neighboring ones Splash and the ends of the outer jacket of the bearing sleeve on three sides closed ring pockets for the Lubricant without touching the shaft and on the one hand without, on the other hand, eliminating the small axial play of the Madel rolls.

Between the lips and the wave there is mainly an I.

good gap seal formed, which on the one hand the exit of the |

Lubricant and on the other hand the entry of dirt far-]

goxiu.

With this design of the roller bearing, the needle rollers are held securely against falling out inwards.

According to a further feature of the invention, the rolling elements are designed as needle rollers ima held and guided by a window cage, the end rings of which connecting the transverse webs are approximately in the pitch circle, while the end edges of the inwardly directed planes lie radially inside the end rings.

It is proposed in particular that the cage bars are cranked inwardly in two stages with respect to the side rings in a manner known per se and with the axially The outer parts guide the needle rollers, while the middle part holds the needle rollers against falling out inwards.

Finally, there is a combination of the above developments proposed, wherein the bearing sleeve with axially inwardly directed lips protruding from the flanges is provided and wherein the needle rollers through a window cage are held and led. Eei such a combination is provided according to the invention in particular that the Lips overlap the cage side rings axially. Here too, as in the embodiment claimed above, the needle rollers with tapered ends, taking care that the lips do not touch the shaft. It is also ensured that

In the vicinity of the flange 13, a radially outwardly directed contact flange 14, which with the flange 13 over an oppositely curved part 15 is connected.

From the radially inner ends of the flanges 12 and 13 are axially inwardly directed, extending over the circumference of the Flange extending lips 18 and 19 in front. These lips embrace the ends of the needle rollers 11, which in this embodiment in tapered guide - pins 16 and 17 merge. So the needles are through the overlapping lips held captive in the bearing sleeve.

In the embodiment shown in FIG. 2, the bearing sleeve of the roller bearing is opposite to that shown in FIG. 1 Embodiment unchanged. The corresponding parts are therefore also given the same reference numerals, with the addition of an additional index "a".

In contrast to the embodiment according to FIG. 1, however, the roller bearing according to FIG. 2 comprises a window cage 2o which, in a manner known to itself, is composed of axially parallel ones. _v uerstegp: i and these connecting end rings 24 and 25 consists.
