The present invention relates to a shaft-hub connection having an attachment flange and a clamping element, particularly a clamping ring, attachable thereto, by means of which the shaft end assigned to the attachment flange may be friction-locked to the attachment flange, with an interposed bushing which receives a slip torque. The present invention is based on the object of refining a device of the type initially cited in such a way that the lifetime of the attached components in the drivetrain is increased. This object is achieved according to the present invention in that the bushing is designed in multiple parts in the axial direction.

Shaft-hub connection

A flexible all-steel shaft coupling includes two connecting flanges ( ) and an intermediate piece ( ) arranged between the connecting flanges, with a disk ring ( ) being arranged between each of the two connecting flanges and the intermediate piece; said disk ring being connected alternately to the respective connecting flange and the intermediate piece, by means of circumferentially-distributed studs ( ) and tension sleeves ( ), each comprising a radially protruding end stop, ( ), as well as spacer rings ( ) held on the tension sleeves, so that the connecting flanges are interconnected so as to be torsionally rigid but with angular movement and axial movement; with each of the studs ( ) connected to the connecting flanges being associated with only a single tension sleeve.

Flexible all-steel shaft coupling

The invention relates to a flexible shaft coupling whose two coupling halves, each comprising a connecting flange, are connected to one another by means of a lamella packet collar so as to rotate together but be axially and angularly movable relative to one another, wherein the lamella packet collar is comprised of several lamellas axially spaced by spacer elements and is fastened by means of circumferentially distributed fastening and clamping elements alternatingly to the two connecting flanges. For reducing or preventing noise which is caused by the bending movements of the lamellas as a result of the angular misalignment compensation, it is provided that the lamellas are connected with one another by an elastic material in a positive-locking manner in that the lamellas are embedded in the elastic material so that the elastic material is also arranged between the lamellas and at the outer sides of the lamella packet collar.

An all-steel clutch having at least one eccentric pack of spring plates which holds the clutch halves axially at a distance in the unloaded condition and is so inclined by an acute angle to the axial normal plane that a slight axial displacement of the clutch halves in relation to one another produces a comparatively large angular offsetting, thereby enabling angular displacements caused by loading to be compensated.

All-steel clutch with adjustable angle of rotation

The invention relates to an overload release clutch having: a hub 2 which is disposed on a shaft 1 and has two coupling halves 3,6 which are coupled with provision for axial disengagement in relation to one another by means of a positive connection 4,5 one clutch half 3 being disposed rotatably and axially secured on the hub 2 and the other clutch half 6 being disposed non-rotatably and axially displaceable thereon, the other clutch half 6 being urged towards the first-mentioned clutch half 3 by a spring arrangement having an adjustable axial force and a snap-over characteristic characterized in that the spring arrangement has a concentric resilient ring 8 which is so borne on the hub 2 by means of radially directed rigid bearing elements 10,21 inclined at an angle to the axial normal plane in the direction of the ring 8, that, when acted upon with an axial force directed towards the direction of inclination of the supporting elements 10, the ring 8 can be radially expanded.

A flexible all-steel shaft coupling with two connecting flanges which are connected by a laminated spring ring arranged between them. The laminated spring ring is arranged on clamping bolts by clamping bushes and is held at a distance from the flanges by spacer collars. A washer with a low-friction coating is arranged between the laminated spring ring and each of the spacer collars. The washers prevent the upper lamellae from wrapping as a result of the rotation of the spacer collars during the bracing of the laminated spring ring, this being the cause of premature breaking of the lamellae.

A flexible all-steel shaft coupling has two coupling halves each comprising a connecting flange and which are axially and angularly movable but antitorsionally connected to each other through a yieldable stapled lamella crown connected to the connecting flanges. Each connection of the stapled lamella crown with one of flanges consists of a bolt on which rests, in clamped position between spacer rings, the stapled lamella crown on a spring collet provided with a conical press seat. Due to its conical support on the bolt, the conical spring collet is radially expanded and transmits radial pretension into bores of the stapled lamella crown. Due to the tolerance-free support of the stapled lamella crown on the bolt, and due to radial pretension in the bores of the stapled lamella crown, the shaft coupling may be easily mounted without precision machning and without tolerance on the support seats, while expansions and ovalizations of the bores, which lead to ruptures due to notch corrosion are prevented.

The invention relates to a torque-limiting clutch. An engagement lock (2, 8, 9, 11, 12) and a friction clutch (6, 20-26) disengageable counter to the force of an axially acting spring are arranged in series in the force transmission path between the drive side (1) and the power take-off side (26) of the clutch. The engagement lock (2, 8, 9, 11, 12) is stressed by a second spring which, when the engagement lock has been disengaged, acts on a first portion of the adjustment travel only. Assigned to the locking device (9) of the engagement lock (2, 8, 9, 11, 12) is an ascending curve, the steepness of which is greater over the first portion of the adjustment travel than over the portion adjoining the latter. In this clutch, the limiting torque is determined solely by the second spring. Whereas the steepness of the first portion is chosen so that the engagement lock reacts after the limiting torque, the steepness of the second portion can be chosen, taking into account the two springs which are then activated simultaneously, so that the clutch can be disengaged easily and quickly.
