Abstract
A shaft-hub-connection has a shaft with an external face portion seating in a first bore portion (6) of the hub (3). A tensioning screw (19) is provided with a head which is supported on a support disk (11). The disk is non-movably held in an axial direction on the hub (3), in the tensioned condition where the threaded shank (22) sits in the threaded bore (18) of the shaft (14). A nut (23) is between the support disk (11) and the shaft (14). The nut (23) is on the threaded shaft (22). This nut (23) is non-movably retained on the shank. When actuating the tensioning screw (19) in a disconnecting direction the nut (23) abuts the support disk (11), so that the hub (3) and the shaft (14) move away from each other and become separated.
Claims14
The shaft-hub-connection comprising:
- a hub;
- a first front face and a second front face arranged parallel to the first front face on said hub;
- a first through bore in said hub extending between the first and second front faces and centered on a longitudinal axis, said first through bore having a first bore portion;
- a support disk having a second through bore, said support disk being non-movably positioned along the longitudinal axis of the hub at the end of the first bore portion close to the second front face;
- a shaft having an external face portion form fitted to the first bore portion of the hub, said shaft being centered on the longitudinal axis;
- a threaded bore in said shaft starting at a front face of the shaft and centered on the longitudinal axis;
- a tensioning screw having a head and a threaded shank, said tensioning screw being screwed into the threaded bore starting from the second front face of the hub through the second through bore of the support disk, and a nut non-rotatably retained on the threaded shank between the support disk and the front face of the shaft with a gap formed relative to the support disk;
- and
- wherein the first bore portion of the hub and the external face portion of the shaft received in the first bore portion, being formed such that, starting from a specific insertion depth of the shaft into the first bore portion, a frictional resistance acts to oppose tensioning of the external face portion and the first bore portion.
The shaft-hub-connection comprising:
- a hub;
- a first front face and a second front face arranged parallel to the first front face on said hub;
- a first through bore in said hub extending between the first and second front faces and centered on a longitudinal axis, said first through bore having a first bore portion;
- a support disk having a second through bore, said support disk being non-movably positioned along the longitudinal axis of the hub at the end of the first bore portion close to the second front face;
- a shaft having an external face portion form fitted to the first bore portion of the hub, said shaft being centered on the longitudinal axis;
- a threaded bore in said shaft starting at a front face of the shaft and centered on the longitudinal axis;
- a tensioning screw having a head and a threaded shank, said tensioning screw being screwed into the threaded bore starting from the second front face of the hub through the second through bore of the support disk, and a nut non-rotatably retained on the threaded shank between the support disk and the front face of the shaft with a gap formed relative to the support disk;
- and
- wherein the first bore portion of the hub and the external face portion of the shaft received in the first bore portion, being formed such that, starting from a specific insertion depth of the shaft into the first bore portion, resistance exist due to the shape of the external face portion and the first bore portion and/or a frictional resistance exist both of which act to oppose tensioning of the external face portion and the first bore portion.
