ABSTRACT:
A coupling bearing for rotors running above critical speed, in which the bearing encloses the rotor and is connected and disconnected depending on radial rotor movements. A gap is provided between the coupling bearing and the rotor, and this gap has a predetermined space width which is at least as large as the maximum amplitude of the rotor in the nominal operating range. A starting bushing permits brief sliding of contacting surfaces, and is made of a highly wear-resistant and self-lubricating material of low heat conductivity. The starting bushing, furthermore is ball bearing mounted. The coupling bearing is in the form of a ball bearing connected with a damping device, and the inner race of the ball bearing seats the starting bushing. The inner race and the balls of the bearing are made of material of low specific gravity, high heat conductivity and high temperature resistance. The inner and outer races of the ball bearing, moreover, are made of light-weight material containing a temperature-resistant lubricant, and the outer race of the ball bearing is contained in a damper body of high heat conductivity.
