The second conical part (9) has an axially extending portion (9a), which terminates in a spring abutment (15, 16). A spiral spring (21) is placed around the extending portion, the other end of which engages against a radially directed leg portion (20, 24) of an angle ring (18, 25) which overlaps a radially extending stop (17, 22) formed on the outer conical part (9).

Abstract: A detent arrangement is disclosed for the coupling pin of an overload element, particularly in an overload clutch, wherein a coupling pin is in form-locking engagement with the oppositely disposed clutch half, with such engagement being released when there is an overload; at its rear end, the pin is provided with the detent arrangement. This detent arrangement surrounds the rear pin end with a spring arrangement which is partially supported at the housing that accommodates it and otherwise at a collar of the coupling pin, with one end of the spring arrangement being supported by means of a slide ring and a plurality of locking elements that extend toward a cone envelope face of the coupling pin and a contact face of the housing.

Abstract: To permit rapid axial relocation of cutter rollers or cutter wheels (2, 3; 11; 42; 78, 121) on supporting shafts (6, 7; 70, 71; 100), the cutter rollers are located on respective positioning or carrier rings (12, 41, 74, 75; 102, 120 130) surrounding the respective shafts, and are axially clamped in position by a rotatable operating ring (13, 22, 28, 40, 52, 88, 89; 107, 126, 138), rotatable about said positioning ring. The operating ring is rotatable, for example by being operator-accessible, at any circumferential position of the shaft, a hydraulically operated compression sleeve, or the like, so that the axial position of the cutter roller or wheel can be changed on the shaft regardless of the circumferential position of the shaft when it comes to rest after having cut a web into a ribbon, the width of which is to be changed.

Abstract: The invention relates to an apparatus for coupling a shaft or a hub by means of a radially resilient bush, which can be radially clamped to the shaft or hub by axially tightenable clamping elements by exposing the clamping elements to a radially operative spring assembly; the release of the coupling is effected by means of a hydraulically- or pneumatically-actuated cylinder and piston arrangement. The nucleus of the invention is that the spring assembly is accommodated in the cylinder chamber acted upon by the pressure fluid.

Abstract: To prevent torsion and bending forces from being applied to an operating ring disk system pressing together interdigited elements of a ring disk clutch, and to permit placement of ring disk portions close to each other for maximum engagement force being applied to the clutch, the ring disk system is formed of a plurality of parts (27, 34, 41 45) which are essentially sector-shaped, surround the clutch shaft, and are pivotable about a movable fulcrum (11, 20) which compresses the clutch disks (3, 5). The individually separate ring disk system parts or elements are in outer circumferential engagement to abut each other and to hold the parts in essentially clearance or play-free mutually engaged position, regardless of whether the rings disk system is flat or planar, or deflected into conical shape. Further, the parts are formed with an inner engagement arrangement to hold them in mutually aligned and supported radial position. The parts can, additionally, be held axially in position.

Abstract: An apparatus is proposed for releasably locking a bolt in the axial direction relative to a housing element surrounding it, in which the bolt has a circumferential groove tapering radially inward and a locking element inserted into this groove with a cross section adapted to that of the groove. The locking element protrudes radially beyond the cross section of the bolt and is in contact there on both sides with support surfaces, one of which is formed by the housing and the other of which is axially displacable under a compressive force load; at least one of these support surfaces is inclined, to provide a radially outwardly oriented reduction of the cross section formed between the support surfaces.

Abstract: The invention relates to a method and an apparatus for measuring the torque passed through a rotatable machine element, in which two parts connected to this machine element rotate relative to one another. This relative rotation is translated into an amplified axial movement, and the axial movement is measured as a standard for the transmitted torque.

Abstract: To provide a compact clutch, two clutch parts (1, 2; 44,54,55,73,74) are located in axially fixed position on respective driving and driven shafts. The clutch can be automatically disengaged upon transfer of excessive torque, by including bolt elements (16,61) which are positioned circumferentially around one of the clutch elements (2) and parallel to the axis of rotation (17,60) of the clutch, the bolt elements carrying directly, or engaging respectively tooth or tooth gap elements which are shiftable axially against a bias force, for example provided by a spring (22).

Abstract: An overload coupling having coaxially arranged coupling halves. At least one of the coupling halves is axially displaceable and is held by spring force in form-fitting engagement with the other, and the coupling halves have a face gear on their facing ends for effecting the form-fitting engagement. The flanks of the gear-tooth system that rest on one another during torque transmission generate an axial force component, which acts in the direction of disengagement, and a radial force component. The axially displaceable coupling half is embodied such that it is radially variable counter to a restoring force.

Abstract: To permit unloading and release of statically stored dynamic energy in a run of a loaded conveyor, e.g. a mining conveyor belt, the return stop mechanism or back-run safety mechanism is coupled to a fixed structure, such as a frame (50, 73, 89) through a releasable friction coupling which is formed by a two-part holding ring (48, 49; 71, 72; 87, 88) coupled to the frame, and having facing inwardly directed surfaces which can be clamped, by controlled friction force against facing surfaces of an outer operating ring (45, 64, 84) of a ratchet or other one-way clutch or drive to prevent back-run or a return stop for the conveyor. Upon controlled release of the frictional engagement, for example by counter-acting spring force or releasing a spring force, the friction surfaces are permitted to slip, thus permitting dissipation of stored energy in the conveyor, for example due to sudden stoppage upon malfunction or external interference, for example by rocks, boulders or the like.

Abstract: A retainer ring for a freewheel clutch comprises an annular disc and a plurality of sprag-guiding clips mounted on a radial face of the annular disc in a circumferential distribution about the disc axis.

Abstract: A device for rotating a reciprocating valve executing alternating opening and closing strokes has an overrunning clutch coupled to the valve stem; a control lever; a first articulation connecting the control lever to the overrunning clutch; and a second articulation supporting the control lever at a distance from the overrunning clutch. The control lever is arranged to impart to the overrunning clutch a torque derived from the reciprocating motion of the valve. The overrunning clutch transmits the torque to the stem for effecting rotation thereof about the stem axis solely during the closing strokes. The second articulation is situated at a predetermined fixed location selected such that a line connecting the articulations defines a first angle with the valve stem axis at the end of each closing stroke and a second angle at the end of each opening stroke. The first angle is acute and the second angle is at the most 90.degree. and is greater than the first angle.

Abstract: A combination of a sprag clutch and a deep-groove ball bearing has a cage ring made of two identical radial halves. Each cage ring half has circumferentially spaced first recesses each accommodating and pivotally supporting a spring-biased sprag; circumferentially spaced alternating pockets for captively holding a bearing ball; and second recesses each nestingly receiving a bearing ball. The number of pockets and the number of second recesses in each cage ring half each equals one half the number of bearing balls in the ball bearing. The two cage ring halves are staggered with respect to one another to the extent of one bearing ball pitch, so that with any pocket on either cage ring half there is axially aligned a second recess in the other cage ring half.
