Abstract
In a method for firmly connecting a shaft to a rotor-housing part, the rotor-housing part is provided having a bearing flange and the shaft is provided having a recess, extending in the circumferential direction of the shaft, on an outer circumference of the shaft. The shaft is inserted into the bearing flange such that the recess and the bearing flange overlap one another. Material of the bearing flange is introduced into the recess. With the connection, created in this way, between the shaft and bearing flange, a high press-out force is achieved.
Claims11
A rotor-housing part, comprising:
- a bearing flange, and
- a shaft having a recess on an outer circumference of the shaft, the recess extending in a circumferential direction about a longitudinal axis of the shaft,
- wherein the shaft is inserted in the bearing flange, wherein material of the bearing flange engages in the recess such that the shaft is connected to the bearing flange, wherein a press-out force of the shaft in at least one press-out direction is at least 5 kN at a temperature of 23° C.
