Friction-disk transmission comprising a tiltable disk.

摘要

The invention relates to a friction-disk trans­mission with a first shaft (19) and a coaxial second shaft (23) which are rotatable about a common axis of rotation (Z), the first shaft (19) being coupled with a disk (1) which is tilted with respect to the axis of rotation (Z) and engages with friction a disk-shaped supporting member (11) secured to the second shaft (23) and rotatable about the axis of rotation (Z). The disk (1) is supported in an annular spring (3) and is tiltable about two axes (X,Y) which intersect each other perpendicularly and are located in a plane at right angles to the axis of rotation (Z). The tilting point (P) is located substantially at the point of intersection of the X-, Y- and Z-axes. The rota­tion of the disk (1) about the Z-axis is blocked by the annular spring (3). The friction-disk transmission can be used in apparatus requiring comparatively large transmission ratios, more particularly if a vacuum-tight separation is de­sired between the first and the second shaft.
