Bearing arrangement for rotatably supporting a planetary gear on a planet carrier

摘要

The invention relates to a bearing arrangement for the rotatable mounting of a planetary gear (4) on a planetary carrier (2), with two tapered roller bearings arranged at an axial distance from each other (8, 10). In order to increase the carrying capacity of the bearing arrangement, at least one radial bearing (12) is arranged in the space remaining between the tapered roller bearings (8, 10). The at least one radial bearing may be formed, for example, as a cylindrical roller bearing, needle roller bearings, ball bearings or plain bearings. In order to distribute the bearing capacity of the bearing assembly uniformly, it can be provided that the radial bearing arranged between the tapered roller bearings is adjustable with respect to the bearing clearance or a bearing preload.
