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.

Overload release clutch for the transmission of rotary movement between

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.

Torque-limiting clutch

A drive mechanism for a rotary drum having a toothed ring which is disposed on the outer periphery thereof with a clearance in relation to the drum and which meshes with a drive pinion, the toothed ring is secured to a cylindrical support arranged concentrically to and with a clearance from the drum, and mutually spaced circumferential portions of the cylindrical support are respectively secured to the drum and to the toothed ring, the support being elastically flexible whereby the toothed ring is able to move radially of the drum with flexure of the support. The toothed ring is held in mesh with the drive pinion by guide and support elements which are disposed at the same radial distance from the drive pinion axis but which are angularly spaced about the axis and bear on an inner peripheral surface of the toothed ring.

Drive mechanism for rotary drum

A coupling apparatus where two coaxially held coupling halves are connected by a tensioning member provided with a predetermined breaking point. The tensioning member secured at one end to its associated coupling half, is radially and tangentially displaced with respect to the end of the tensioning member secured to the other coupling half. At the overload condition, one coupling half makes a complete rotation, after breaking, with respect to the other coupling half. A rotary escapement is provided as a holding structure so that when one element of the tensioning member swings, it does so out of the path of the other.
