Abstract
A sleeve element is installed between two hollow gear shafts which are rotatably coupled relatively to each other by a bearing. The sleeve has a hollow cylindrical body which is received inside one of the shafts. The sleeve has a plurality of slots in one end thereof which permit lubricating oil to flow to the bearing. A plurality of spring elements project from the other end of the cylindrical body. The spring elements engage the one shaft and are biassed to urge the one end of the body against an end surface of the other shafts. The force of the spring elements is active at least during primary assembly of the shafts. At a particular temperature, such as the operating temperature of the shafts, the spring elements lose their force. Preferably, the spring elements and the cylindrical body are integrally formed of one part.
