Patent DE-3907933-A1 (DE)
Title: Positive shaft-hub connection
Inventor: MOSIG ERNST
IPC: F04D29/26
Filed: 1989-03-11
Abstract: A positive shaft-hub connection is specified, which is designed to be easy to mount and dismount. Attached to a driven part, which may for example consist of plastic, is a driver which may be produced as a flat-spring part, for example of spring steel. This driver is displaceable along a guide on the driven part perpendicularly to the axis of the driving and driven part into a connecting position in which the driving part is grasped. At least parts of the longitudinal guide can at least partly grip around the driver. For the release position, a stop is present on the driven part which limits the displacement movement of the driver to such an extent that the driver remains reliably on the driven part even in the release position.
