Abstract: In a bearing for the rotor of a rotary device, preferably a spinning turbine, the bearing being composed of an oil-lubricated slide bearing bush and a journal pin connected to the rotor and mounted to the bush for rotation relative thereto, the bush presenting a cylindrical surface providing support for the pin in the radial direction, and elements for yieldingly mounting the bush, there is further provided a bearing mounted to rotate with the rotor and having an axial end face forming, with an axial end face of the bush, an axial slide bearing for the rotor, the axial bearing receiving a supply of lubricating oil during rotation of the device, and a structure defining a narrow annular gap in the vicinity of, and spaced radially outwardly from, the axial slide bearing to provide a constricted region adjacent the axial bearing at which lubricating oil ejected from the axial bearing accumulates.

Abstract: In an open end spinning unit having a stationary frame member and a spinning rotor rotatably supported by the frame member, and in which, during operation of the unit, a flow of gas occurs from the yarn removal opening and fiber inlet opening of the unit to a gas extraction opening thereof, the gas traversing a path surrounding the rotor, a gas flow controlling structure is disposed around the rotor to define a narrow gap with the exterior surface of a portion of the rotor, so that the space adjacent the remainder of the rotor is in communication with the gas flow path only via the narrow gap.
