Abstract: A bearing arrangement may be used to mount a worm shaft meshing with a worm wheel in a housing of an electromechanical power steering system. The bearing arrangement comprises a first rotary bearing, a second rotary bearing, and a pivoting ring. The first rotary bearing is configured to permit a pivoting movement of the worm shaft. The pivoting ring comprises a first pivoting ring component and a second pivoting ring component and is configured to act resiliently between the second rotary bearing and the housing. The second rotary bearing is at least partially arranged between the first pivoting ring component and the second pivoting ring component. The first pivoting ring component has two first points, with respect to which the first pivoting ring component is configured resiliently. The second pivoting ring component has two second points, with respect to which the second pivoting ring component is configured resiliently.

Abstract: An electromechanical power steering system may include an electric servomotor that has a motor shaft and drives a shaft that meshes with a helical gear. The shaft is disposed in a gearbox housing and rotatably mounted in a bearing assembly. A pretensioning installation, for adjusting engagement between the helical gear and the shaft, resiliently pretensions a movable bearing element of the bearing assembly relative to the gearbox housing. The gearbox housing has a housing portion having first and second contact faces, the normals of which do not intersect. The bearing assembly has a bearing support that forms the movable bearing element and has a lever arm having a free end that extends from a main body of the bearing support and on the gearbox housing lies against the second contact face. The main body has an eccentric cam that on the housing lies against the first contact face.

Abstract: An electromechanical steering system may include a reduction gearbox where a worm gear is mounted in first and second bearings rotatably about a longitudinal axis. Rolling elements are disposed between inner and outer rings of the bearings. The inner rings are rotationally fixed on a shaft driven by the worm gear. A spring element is disposed between the inner ring of the second bearing and the worm gear. The spring element has an at least partially annular main body that when installed extends coaxially with the longitudinal axis. Spring arms in a circumferential direction are spaced apart from the longitudinal axis emanating from an external circumferential side of the main body. A first spring arm has a first leg that points away from the longitudinal axis and a second leg on which a free end is disposed, with the second leg running at least partially parallel to the longitudinal axis.

Abstract: A machine for extracorporeal blood treatment including a housing for accommodating operational components of the machine for extracorporeal blood treatment and a light-emitting unit having no diffusion disk for displaying an operating and/or therapy condition of the machine according to the principle of ambient light. The light-emitting unit is arranged in a predetermined sequence and/or with predetermined shaping on at least one portion of the housing. The light-emitting unit is a flexible light conductor having at least one end-face light coupling surface at a first end and at least one end-face light output surface at a second end or alternatively a self-luminous flat and/or flexible OLED unit.
