Abstract: A turbine rotor for an exhaust gas turbine has a turbine rotor wheel made of a highly heat-resistant metal alloy and a rotor shaft made of steel. A rotor wheel hub and a rotor shaft end are connected to each other in a metallurgical bond by way of a solder connection. The rotor shaft end and/or the rotor wheel hub is formed with a central recess, which acts as a thermal choke. A closing plug is arranged in the respective recess, forming a closed cavity with the recess and closing off the recess toward the respective end face. The solder connection is formed between the end faces of the rotor wheel hub and the rotor shaft, between the closing plug and the rotor wheel hub, and between the closing plug and the rotor shaft.

Abstract: A resilient radial sliding bearing is intended for connecting parts, particularly motor vehicle parts which perform oscillatory movements relative to each other. The bearing comprises a resilient body of elastic material, having a slide surface which is provided with recesses for a lubricant and cooperates in rotary motion as well as, within limits, axially sliding motion, with an opposite surface of a sliding sleeve. A mounting for the bearing comprises a sleeve member having downturned edges which engages over the sliding sleeve and each end of the resilient body and limits the axial sliding movement of the resilient body to a defined clearance.

Abstract: A resilient bearing comprising a resilient body of an elastic material which is clamped between an outer sleeve and an inner sleeve and provided at both its frontal sides with cavities reaching inside up to the center of the bearing and being angularly offset relative to each other. In the zones of solid material, the resilient body is prestressed so that upon deflections in any direction, the parts are positively returned to their initial mutual position.
