Abstract

A wheel bearing for aircraft. The bearing has a long service life, is very reliable and consists of the lowest possible number of individual parts. The wheel bearing of an aircraft engine has a rim that is rotatably mounted about an axis by a bearing arrangement which has two rolling bearings. An outer bearing housing, designed as one piece, contains the outer running surfaces of the rolling bearings. An integral component of the outer bearing housing forms part of the rim and the outer bearing housing is detachably connected to the remainder of the rim.

Claims (7)

1. A wheel bearing for an aircraft landing gear, comprising:

a rim, which is mounted rotatably about an axis via a bearing arrangement, haying two anti-friction bearings;

a bearing outer housing which is designed as a single piece part, and outer running surfaces of the anti-friction bearings are directly formed on the bearing outer housing; and

two inner rings on which the two anti-friction bearings respectively roll, the inner rings configured to be mounted on an axle and clamped in series between an axle nut and a shoulder, the two anti-friction bearings each comprising tapered rollers,

wherein an integral component of the hearing outer housing forms a part of the rim, and the hearing outer housing is connected releasably to a rest of the rim,

the bearing outer housing having a radially outwardly extending projection that has a radially outer circumferential surface disposed so that the circumferential surface is in an interior of a tire that is finable onto the rim.

2. The wheel bearing of claim 1 , wherein the bearing outer housing is arranged in a part of the bearing arrangement which is freely rotatable about the axis.
